Question
It's been raining here for 12 days straight, and our metal roof seems to be leaking in a few spots. The roof is old, but I guess these metal roofs can last forever if properly cared for. There are no glaring rust problems, but a few spots with some faint discoloring through the last coat of paint. I should have worked on it this summer, but now I'm stuck waiting for a break in the weather before winter hits to get up there and paint the roof. If anyone has advice for painting the roof, or answers to any of these questions, I would be very appreciative.

1) What are all of the steps to painting the roof? (I've read about a pressure washer...is there other equipment I should be looking into renting?)
2) What are some tips for making the job as safe as possible?
3) What kind of paint specifically should I be looking for?
4) How long should I allow for the paint to dry before the next rain/snowfall?

Thanks for your quick response. I think I see that the rain should stop for a few days this weekend...Maybe I can climb up there then.

Answer
Good Morning M.G.
The Shower-Proof "WB" would work in all areas but preperation will be the key. The entire roof must be cleaned maticulusly by washing with TSP (Tri-sodium Phasphate) and by powerwashing with a 3500 psi powerwasher.  You will need to remove as much of the old coating as you can with the powerwasher and by scraping because it is the old layer of tar and paint that has the most chance of failing. Shower-Proof "WB" will adhere to old paint and asphalt. (When cleaned well).  Once the roof is prepared, you may spot all rusted areas with Calbar 10-520 rust inhibitive primer, and then top coat with the Showr-Proof. If you would like to add life to the job, as well as a gloss surface, you may add the Shower-Proof Clearcoat.  Please feel free to contact us with any additional questions.
Thank You

Question

Comments: I am about to paint a galvanized sheet metal ceiling in a temple.  (not a roof) it is 25 X 60 feet in size.  I need to strip the paint that is currently peeling off the ceiling and then clean the ceiling and prime it and paint it.  It is a big job, so any recomendations on products and procedures would be greatly appreciated.  the temple is about 90 years old and the metal ceiling is directly attached to the wood beams and lath in the attic.  There are areas that the metal is buckled and needs to be srewed into the beams as well.  Thank you.
 
 

Answer

Hello Robert
You didn't mention what surface sheen you wanted to have when you were done. I'll assume that you would want a low sheen white for your ceiling. I suggest one coat or our 10-530 white phenolic primer, topcoated with two coats of # 88 Acrylic Latex Low_Sheen paint. This combination, when applied correctly, will give many years of life to your galvanize ceiling. Please let me know if we can help in any way.

Question

Comments: We have a galvanized aluminum building that we are going to
pressure wash and then it needs to be primered and painted.  The primer
needs to cover where the pressure washer has pealed off the old paint but
left some of the paint still on the building.  We want the surface to be
smooth when the paint is applied.  Any suggestions will be appreciated.

Answer

Good Morning
You can certainly prime inside the areas where the paint has been blown off but unless you take all the paint off, there will always be a profile where the two surfaces meet. The best thing that you can do is to apply our low sheen siding paint instead of the Semi-gloss siding paint.  The low sheen will not enhance the irregular paint surfaces and go a long way to masking the irregularities. We will send you a brochure of the low sheen siding paint as well as the primer that you can use on the rusted  or unpainted areas.
Thank you

Question
I was reading the the brochures and was wondering what is the different from the metal siding paint and the WB showerproof paint?  Can one apply the metal siding paint on a metal roof??? Thanks. candice
Answer

Your question is a great one and one that we get asked all the time. I cannot emphasize enough that there are great differences between a vertical siding paint and metal roof paint.



  • Calbar Metal Building Paint represents the best technology in high performance, water based, 100%  acrylic paints, formulated and developed specifically for use on exterior metal siding panels.  It has tenacious adhesion, and dries quickly for a long lasting decorative and protective finish. Calbar Metal Building Paint resists peeling, fading and blistering, and exhibits exceptional film durability and color fastness. This product is low odor, mold and mildew resistant, and coats most surfaces without a primer.

  • Showerproof "WB" is a metal roof paint unlike any other that we are aware of. Calbar Metal Roof Paint has been manufactured continuously for more than 85 years. The ingredients we use are essential for the success of any roof paint.
    I’ll explain. Your metal roof structure is a surface that endures more harsh treatment than any other surface in your home. During the summer, your metal roof could reach temperatures of 180 degrees or more. Most paints are not equipped to handle the constant heating and cooling that a metal roof will endure. When we manufacture our roof paint, we include ingredients that guard against color fade, salt and chemical spray, thermal shock, thermal buildup, rust, chalky surfaces, expansion and contraction, ultra violet rays, and a host of other events that will affect the performance of your roof and its protection. Do not allow someone to tell you that all metal paints are alike, as far as we know; there is none like Showerproof "WB".

Comments: I am very interested in your product.  We have a tin roof on our
house that needs astetic help as the nails have rusted and streaked the
tin roof. It works well just not attractive. Can your product help???
Where can it be purchased?  Is there anyone in New Mexico that handles
your product?? Or in Southern Colorado?? Thank you. candice
Answer

Hello Candice
Yes we can help! You didn't mention it but I assume that you roof has a factory applied finish, but even if you have a galvanize finish, the cause of the rust, and the solution for its remedy are the same. When the roof was installed, the roof panels were coated with a weather resistant factory finish, and if they could have been installed without fasteners, the factory finish would have been protected for years. The problem comes when any part of the original finish is punctured or sliced through; the cut exposes raw metal that will rust easily. Often times a roof will only be rusty where the overlapping seams have been cut for installation. Eventually, if left untreated, the entire finish will deteriorate resulting in the need to reroof your house or barn. The other thing that you did not mention is how old your roof is. At some point, the rubber grommets that are under the nail head will begin to deteriorate, (ultraviolet rays are especially fierce in the area where you live) and they will require a treatment. You may want to treat them now before you apply the finish coat of paint thereby adding a preventive maintenance step as well as beatification to your project. So, here are the steps necessary to restore your roof. 1.) Power wash your roof to remove contaminants that would interfere with adhesion. 2.) Wash your roof down with a solution of TSP (Tri-Sodium Phosphate). If any mildew is present, add some Bleach to your TSP solution. 3.) Spot prime any rusted areas with 10-520 rust inhibitive Roof Primer. 4. Optional) Treat every nail head with a coating of CRS (Calbar Roof Seal) Moisture Cure Urethane. 5.) Apply two coats of Showerproof "WB" in the color of your choice. 6. Optional) Apply one coat of Showerproof Clear Coat. This will give a Semi-gloss appearance and add additional life to the overall application. Thank you for your question.

Question
Comments: My 1880's home has two porches with what I think are "tin"
roofs. How can I tell if they are actually "tin" or "galvanized"...what is
the difference? I used an oil-based or linseed paint when they were last
painted, about 6 years ago. Now I'd like to use a water-based paint and
rust-preventative but don't know if this would work? Please answer ASAP.
Thanks!
Answer
Hello Christine
The difference between "tin" or Terne roofs and Galvanize is that Terne roofs were made with a lead coating and Galvanize is made with a zinc coating. Unless you can see the spangling (little geometric shapes in the metal), there is no sure way that I know of to tell if it is galvanize. A roof the age of yours is more than likely lead coated especially if it is a standing seam roof. Regardless of the makeup of the roof, The Showerproof "WB" and the 10-520 rust inhibibive primer would work well in your situation. They would also give you more paint life that the oil based. Two coats of Showerproof "WB" will last at least 10 years and longer if top coated with the Showerproof Clear coat. Thank you for your question

Comments: I have an old shed with one of those wavy tin roofs that leaks.
What type of product could I paint onto the roof to seal it against water?
 

Answer

Hi Patrick
Metal roofs leak in many different ways. Each one has it's own repair.  Your fasteners may be leaking which would need our CRS (Calbar Roof Seal). Leaking seams, flashing or rusted through holes will need CRS and Calfab (Mesh). When the repairs have been made, you may topcoat with the Showerproof "WB" color of your choice. Let me know if I can be of further help.

Question

Comments: I just had a new galvalume roof put on my house after 1 or 2 rains Ive noticed some areas of rust where the metal filings were left after cutting and fitting the roof panael also the edges that were cut are now showing a coat of rust. Any advice would be great.
thanks Richard Wecker



 

Answer

Good Morning Richard
Without seeing the roof it will be hard to give you perfect advice,but I can give you some ideas.
The filings on the roof have probabaly already become sacrificed into the zinc coating and will remain a part of the roof. The rust color you see has probabaly not formed into rust yet, (Iron Oxide) but has formed Zinc Ferrite as the zinc on the roof has encapsulated the filing. 
The cut edges are another issue. The discoloration showing on the edge is also Zinc Ferrite but if left untreated or unprimed, it will turn into rust (Iron Oxide). Evenuually you will need to repaint the roof for esthetic purposes. We can supply a primer for your seams but I would suggest that you take this matter up with your installer.
I hope that we have been of some help

How much rust can be allowed?

Answer

Hi Alan
Rust is not a problem in any quanity as long as it is spot primed or fully primed using Calbar 10-520 rust inhibitive roof primer.  The powerwashing will get rid of the scaling rust but the metal still needs to be sealed with the primer

Question

A few years ago, I planted some ivy that grew out of control after a few slow years. After covering the chimney, it grew sideways across the windows, under the aluminum siding, and started to grow under the new roof shingles. I got concerned that it might damage the roof shingles and cover the windows and siding, so I pulled off as much as I could. However, the little tendrils left ''footprints" all over the siding that I can't get off. If I were to use something abrasive, it would damage the yellow siding. They haven't become less noticeable with the passing of winter. Do you have any suggestions?


 

Answer

It is a common problem. Too much ivy can be a hazard, mostly on wood and other kinds of siding. It's pretty well harmless on masonry, except on top of chimneys. Here's how to tackle the little beggars: Give each tendril spot a generous dab of raw or boiled linseed oil. Any oil will work, but linseed seems to work very well. (Do not boil oil to get boiled linseed oil; it is already boiled or chemically treated.) Leave the oil on the tendril spot for 15 minutes or more, then scrape with a wood scraper or scrub with a rough cloth. Wash off the oil and you are home free. Repeat as needed. The oil softens the tendril enough so it can be scraped. What is a wood scraper? A piece of wood with an edge sharp enough to scrape off the tiny tendrils.

Question

Comments: On our farm we have a metal silo approximately 30 feet tall with a diameter of 10 feet. It may be galvinized metal but is quite old. It has been spray painted with a heavy coat of white latex. There is a build-up of paint at the joints with some rust "bleeding through the paint. Overall there is not too much rust showing. What do you reccomend for prep and priming? We have new Northstar metal siding on the adjacent barn and hope to match the color (clay) Approximately how much of which product (paint and primer) do we need? Thank you


Bill Spiker 

Answer

Hello Bill
As far as I can tell, your silo is about 1000 sq feet. That would translate to 5 gallons of top coat needed and perhaps a couple of gallons of rust inhibitive primer for the seams. I'm not sure whether or not any of our standard colors would be a good match for your "clay" color but a custom color would require a 25 gallon minimum. Please send us your address if you would like to see a brochure and color chart on the product. Thank You

Question

Hi Jim:
I own a house that was built in 1881.  It has a metal roofar ound a third story cupola.  It needs some help.  Do you know of any way that I can tell if it is terne, versus some other metal.  Also, when cleaned prior to painting with your Tin-O-Lin, how critical is it to get
EVERY bit of rust?  By rust inhibitor, does that mean it can stop rust once coated?
A couple more questions after further reviewing the website. Does the primer only come in red? Also, I assume two coats of the Showerproof WB is recommended? And finally...could you mail me color samples of the paint?  There are traces of a green patina paint on the tower.  I would re-do it in this color if it is true.  The website color makes it look a little olive colored.  Actually send the gray color too, as this would be my second choice.
Thanks so much.


 

Answer

Hi Amy
At this point it would be very hard to determine which metal composition was used. You may be able to find out what type of metal was used historically in your area.  I assume that the roof is a standing seam roof which could have been manufactured by Follansbee metal in West Virginia, but there is really no way to be sure. All of that aside, unless you are attempting to maintain the historical significance of your roof paint, We would recommend that you use the Showerproof "WB" roof paint and 10-520 primer. The 10-520 will drastically inhibit the growth of rust in your metal, and the "WB" will beautify it for many years. Since it sounds like an area that you may not want to have to reach again for a long time, I would also suggest topcoating the "WB" with Showerproof Clearcoat. The Clearcoat will inhance the color and add years of protection to the copula.

Question

Comments: I have an area of roof which is peeling and may have perforated. certain areas have mastic which is coming loose. I am proposing pressure washing to remove the loose material and loose mastic. What paints should I apply on top to resolve the problem.

Answer

Good Morning Howard
I'm not sure what you mean by the word perforating, but if you mean it is spliting and leaking, that can be repaired by using the Calbar Roof Seal (CRS) and mesh. If you have any rust on the roof, you will need to spot prime the rust with Calbar 10-520 primer, after which you may topcoat with two coats of Showerproof "WB".   To prepare the roof for painting, powerwash the entire surface with a 3500 psi powerwasher. Add some Tri-sodium phasphate to your powerwash system or brush it on seperately.  Remove as much of the mastic as possible using the powerwasher and also by beating the roof (not to dent it) with a rubber hose. this will help some or all of the mastic to pop.

Question

Comments: Is Shower-Proof "WB" the best choice for a rusted roof or would
10-520 RUST INHIBITIVE METAL ROOF PRIMER be a better choice?



 

Answer
Actually both products are used in conjunction with each other.  The 10-520 is
used when the roof needs to be either spot primed or fully primed because of
rust, and the Showerproof "WB" is the top coat.  No primer is required for the
"WB" if there is no rust.

Hi,
I have an older home (1840) with 3 different metal roof surfaces.  The first surface is old and it is strips of metal with standing seams and horizontal seams.  It was coated with an aluminum asphalt type of coating and then has been painted twice with an oil base paint.  Paint starts peeling after a year.. 2nd roof is same material but was never coated with aluminum paint.  It's just rusty.  3rd roof is a more modern metal roof say 50 years old and in good shape just dirty and faded paint.  What's the best way to do all 3, I am guessing it may be different for each.  This has been very frustrating because all the local painters want to do is scrape and prime the first roof...but so far that's not lasting.. any help would be appreciated...and obviously I'll use your paint.


 


Dr. Leo Marvin

Answer

Good Morning Dr. Marvin


Thank you for your email.. The reason you are having trouble with the first roof is that oil based paint cannot go over aluminum asphalt or, as you have found, the paint will begin peeling in just a short time.  It is imperative that on all of these roofs, you begin by cleaning the roof using a powerwasher and some tri-sodiumphosphate (TSP) to get as much of the foreign matter and old paint off as possible.  Upon Cleaning the roof thoroughly, you must spot prime any rusted areas with our 10-520 rust inhibitive primer (the 2nd roof).  Upon cleaning and spot priming rusted areas, go ahead and paint the roofs with two coats of our Shower-Proof "WB" metal roof paint.   This type of application should give you 8-10 years of paint on the roof.  If you have any further questions, call us or email us and we would be happy to answer them foryou.  In the meantime, we are sending you brouchures on the products that we area suggesting.

Question

Comments: I have a large steer barn with a metal roof (unpainted).  The roof is starting to rust.  After powerwashing the roof with TSP, I am considering using your ShowerProof WB and 10-520 Rust Inhibitive Primer.I would strongly prefer to use an airless sprayer to apply these coatings. What tip sizes and flow rates do you recommend for each product?  I use a SprayTECH 2155 for other work (3/4 HP. .020 max tip size).  At first blush, it looks like my unit could be used to spray the primer, but might not be large enough to use for your paint. I don't mind renting, just want to sort it out before I start.

Answer

Hi Norm,
You will have no problem spraying either product using a #17 tip.  I am not familiar with your specific gun but i would not expect you to have any problem.  The Showerproof is a similar viscosity to heavy bodied house paint. Also, you will want to take a look at your fasteners before painting to make sure that they are not deteriorating.  If they are, we have a solution for them also.  Flow rate will be determined by you on the job but you will want to make sure that you are getting about 3 wet mils of primer on the roof and 8 wet mils of Showerproof " WB" which will yield 12 dry mils after two coats.  Please feel free to call us if you have any other questions.

Question

Comments: In about 1997 we replaced our roof with metal roofing.  Red
Tin-o-lin was covered with Grey Shower Proof in a period of 7 to 10 days.
The paint last year and again this year is coming off one section in large
strips leaving bare metal.  The grey paint and red undercoat
come off as one piece.  How should we clean and/or treat the metal to make the
undercoat adhere and how long should we let it dry before covering with an
upper coat.  Any suggestions on products and technique would be
appreciated.  Also we have places where the grey has peeled leaving the
red undercoat in place.  What cleaning method will prepare the surface for
touch-up painting.
Thank you,
Diarmuid ("D") Nicholson

Answer
Hello Diarmuid, should I call you D?
I'm afraid that you may have a good deal of work ahead of you. Somewhere in the late 90's, metal roofs went through a change as far as how they are treated in the raw or mill form.  What that means is that "Lead" coated roof metal gave way to "Zinc" coated roofs.  The first thing is to determine which one you have, because oil based paint does not stick to the Zinc coated roofs.  The second thing is that we never recommend putting Showerproof Original over freshly painted Tin-O-lin.  The two products are different in that they have a different " Coefficient of Adhesion". What that means is that the Tin-O=Lin dries at a much slower rate of speed than the Showerproof Original causing the Showerproof to delaminate, usually after it has gone through a winter.  You will usually want to wait one year before topcoating Tin-O-Lin with Showerproof.  We recommend painting your roof with Showerproof "WB", which is the waterbased version of the original Showerproof. It would be better to talk with you in person concerning this so why don't you call us on Monday and we can help you through this. Thank You

Comments: I have been using Tin-O-Lin on my roof for years. The old paint
under my coatings keeps popping and peeling. What should I do and apply?
Secondly, can I apply Shower Proof WB over the Tin-O Lin? Will it adhere?
Thank you
Answer
Good Morning Arthur
Unfortunately, I do not have happy news for you.  Over the years, the Linseed oil roof paint that you have used had built up to the point that it is now a thick hard coating.  Tin-O-Lin is soft and flexible for many years but eventually, all oil based paint will become hard and brittle.  It sounds like the time has come to strip the roof and begin again.  There are many ways of stripping a roof, but none of them are necessairly easy.  You should contact a professional painter who can help you with this matter or call us and we can give you some pointers on strippers.  To answer you question about Showerproof-WB, Yes the WB will go over cured Tin-p-lin and many other roof paints and it will not get hard and brittle because it wears away over an extended period of time.  If you need info on the Showerproof WB, please send us your address and we will send you a brochure on the products that you need.

We have a very old metal standing seam roof that was manufactured by Follansbee steel and is in a historic neighborhood. The roof has a coat of metal roof paint that is badly pealing and has rust showing on about 30% of the roof. Please make a recommendation on how we can restore this roof or would it be better to just replace it? The roof is not leaking but it looks terrible.
Answer
As we say in our literature, "Don't replace your metal roof, restore it for a fraction of the cost" Old metal roofs will last more than a century when they are maintained by keeping a coating of roof paint on them every 5 or 10 years. In your case, based on the information you gave, my recommendations are as follows. ... Powerwash the roof completely ... Wash the roof with TSP (Tri-Sodium Phosphate) and Bleach ... Spot prime all rusted areas using Calbar 10-520 rust inhibitive roof primer ... Paint with 2 costs of Showerproof WB If you have any questions please call Jim at 800 642 9505

Terne is an old english word that I think means "lead". Galvanize is a "Zinc" treatment for metal. It is important to know what your roof is so that you can use the correct paint for each application. Linseed oil roof paint is used for the old Terne roof paint.

I own a house that has a "metal" roof on the garage. The roof is only pitched enough so the water will run off of it. The paint currently on it is chipping and there are spots that are showing rust. I believe it is a sheet metal tin roof about 60 years old. What product should I use and what is the best way to restore it.
Answer
The paint that you need for your metal roof is Showerproof WB. You will need to powerwash the surface and rust with a 3500 psi powerwasher and wash the surface with TSO Tri-sodium phosphate. The rusted areas will need to be spot primed with our 10-520 rust inhibitive roof primer. The fact that you roof is a sheet metal tin roof about 60 years old is not a problem for the water based Showerproof since it is a elastomeric acrylic that will adhere very well to your metal.

Question
Hi, I need to paint the exterior walls of my building. The metal is steel, I think. I need to know if it needs to be treated with anything or primered before painting. The metal has been previously painted and will need to be cleaned first. I also need a price on your paint. It's a 5000 sq. ft. area. I want 5 gallon buckets. Thank you, Laurel
Answer
We will be sending you a brochure on our metal siding paint as well as a brochure on on our 10-520 primer. You will only need the primer if you have rust on your building. Prepare the surface by powerwashing with a 3500 psi power washer and then washing with a solution of Tri-sodium phasphate. (TSP) you can buy TSP at any paint store or we can supply it. Depending on surface profile, you will need approximately 25 to 35 gallons of metal siding paint for a two coat application. freight is free. If you have any more question, please call Jim @ 800-642-9505.

Hello Jim, Can you tell me the coverage per gallon and is primer required. Thank You Tim Brown
Answer
Coverage is 200 sq ft per gal and you will need to put 2 coats on which will give you 12 dry mls of paint on your roof. There is no primer needed if you do not have any rust on the roof. If there is rust, you can either spot prime or fully prime the area. Please feel free to call us with any questions. We are sending you a brochure on the product that you should receive in a few days. Thank you Jim Guy

Question
I am wanting to paint a metal door that has had the paint on it deteriorate in the past, would this paint be good for this application?
Answer
Calbar Metal Siding paint would work well on your metal door. If the original paint is deteriorating, then you have to try to remove as much of the old paint finish as possible. There are waterbased strippers that will accomplish that or you could try washing it with a powerwasher that has a reciprocating spray nozzle. than wash with a solution of Tri-sodium phosphate. If you have any questions you may call Jim at 800-642-9505 Thank You

Question
We have a rolled tin roof on an old farm house that needs to be painted. Previously we used a linseed base paint but can no longer get that finish. What would you recommend? Thank you
Answer
You have a couple of options. You can use the Linseed oil paint that we still manufacture after 85 years, or you can use an Acrylic Elastomeric Watebased roof paint that we usually recommend simply because it is much easier to use. The Linseed oil based paint, called Tin-O-Lin, takes about three days to dry where the water based material dries in ablut two hours. Both are good products. It is your choice. feel free to contact us for further information.

Question
I am remodeling an old (circa 1918) house with a galvanized sheet metal roof of undetermined age. The roof is solid with only a few rust spots and some areas of algae/mildew. It has never had any paint or other coating that I can tell. I would like to paint it, either keeping the original silver/galvanized look, or if feasible change it to a red color that I have seen on some new metal roofs. The problem is that, checking with Home Depot and several paint stores, no one seems to know how to do this and don't have any paint products to recommend. The closest was a Duron store where they had a white primer recommended for galvanized metal. They said I would then have to put a couple of coats of an oil-based (expensive - $30+/gallon) red paint on top of the white primer. It seems like there would be a better, less expensive route. Any product/method suggestions?
Answer
While it is true that TSP (Tri-sodium phosphate) is a great roof cleaner, we always recommend that the roof is first powerwashed using a 3500 psi tip. This will not only remove scaling rust but will also remove loose paint. If there is any mold or algae on the roof, add some bleach to the TSP mixture. When the roof is clean, spot prime all rusted areas with a good rust inhibitive roof primer and apply 2 coats of Calbar's Showerproof "WB" metal roof paint. This application will last for at least 10 years.

It is always important to remove surface debris such as dirt, mildew, and any failing paint. The removal of dust and/or dirt can be achieved with a cold water power washer with a p.s.i. rating of 2500 or higher, a g.p.m. (gallon per minute) rating of 3.0 or higher, and a 15 or 20 degree nozzle for the tip. While its true that power washing removes many surface contaminates efficiently, mildew spores seem to remain stuborn even under the direct assault from a water blast. Chlorinated bleach (Clorox) and a solution of hot-warm water and t.s.p (tri-sodium phosphate) will ensure the complete termination of mildew growth wether it is seen by the eye or secluded. Allow to dry completly. A galvanized metal roof that has been cleaned and mildew-proofed in preparation, should be free of any loose or scaling rust by hand tooling these areas with a wire brush. If there is rust on the roof you will need to prime or spot prime using Calbar 10-520 rust inhibitive roof primer. After the roof has been properly prepared, apply two coats of Showerproof "WB". If you would like a shiny roof, you may apply one coat of the Clear-Kote acrylic gloss coat. Please call us for ordering information @ 800-642-9505

I have been told that there are products that contain Linseed Oil that will keep it from rusting, as well as improving the appearance of my roof. Can you recomend a Paint like this? Does it Work? Where can I get it? How does it get applied? How long will it last? Guarantees? Thanks for any help that you can provide

Answer
Linseed oil roof paints may be purchased from Calbar metal roof paint in Levittown Pennsylvania. They are sold under the trade name Tin-O-Lin and Showerproof Original. I would, however, have you consider very carefully before settling on a linseed oil roof paint because while they had been the standard for over 100 years, they are a little difficult to work with due to the length of time that they take to dry. Tin-O-Lin for instance can take between 3 days and 2 weeks to dry, depending on temperature, humidity and paint thickness. A more user friendly alternative is the product Showerproof "WB". This is an elastomeric acrylic waterbased roof paint that will last for about 10 years when applied according to specs. (8 wet mil, 6 dry mil) We have applied the Showerproof wb by airless spray and it goes on really well, but it can also be brushed or rolled. Good Luck.

Question
Many older historic homes still have their original metal roofs. Some of the roofs we have supplied the paint for are actually 100 years old or more. The original metal roofs were coated with a lead coating, which is the source of the olde English word "Terne". The original Terne, or Terneplate as it was known, is an alloy of lead and tin typically in a ratio of four parts lead to one part tin. Newer metal known as Terne ll is a steel and zinc composition that was the environmentalist answer to lead coated roofs. Metal roofs are known to have an extremely long lifespan, especially if they are maintained throughout the years. Basically, that means that they have to be painted from time to time so as not to rust. Even metal that came from the factory will require paint eventually. When a metal roof is leaking, it doesn't mean that the roof is due for replacement. As a general rule of thumb, a metal roof (that is not rusted) will only leak in one of two areas, the seams and the fasteners. Both of these can easily be repaired using our moisture cured urethane called Calseal and fiberglass mesh called Calfab. This is an easy and relatively inexpensive job for most experienced roofing contractors to do. As long as there is no extensive rusting, roof replacement is not necessary. Even if a portion of the roof is rusted through, replacing the rusted section with a piece of new terne is all that is usually needed. If a metal roof has been tarred over, which unfortunately happens from time to time, it is impossible to see how much of the metal roof underneath has rusted through. If a tarred over metal roof is leaking extensively and is still structurally sound, the roof may be repaired using the moisture cured urethane Calseal. The main issue with metal roofs is maintenance. They must be coated with paint every five to ten years
