repair and coating of metal roof

I am looking for advice on repair and painting of a metal roof. My house is colonial style over 125 years old. It has a steep pitch metal roof with foot square metal shingles that overlap. Wood shingles are underneath the metal shingles. There are many houses with these types of roofs in the northwest corner of Connecticut. I do not know how old the roof is. I have owed the house for 13 years and have not done any maintence work. Currently it has a silver coating and seems to be rusting. The birds have made their way under the shingles at the edges and made nests. This has loosened the shingles. Last summer one shingle flew off in a wind storm. I have recovered the shingle and made a tempory repair. However, the birds are back under the shingles. The roofing contractors I had called last summer to repair the shingle seem uninterested in fixing the problem and only want to replace the roof with some other material than metal. I would like to keep the metal roof and repair and maintain it. Any suggestions?

Michael, This is a pretty complex question which is hard to answer without knowing better exactly what you're dealing with. You know what would be a HUGE help? It would really be helpful if you could email me some photos of the roof, both overall shots and some close-ups. I feel pretty sure I can give you some workable advice for repairing and repainting the roof. I just feel like I need to have a better idea of what product it is and what condition it is in. You can email me direct at [email protected] I hope to hear from you. If you do not have any digital photos, let me know and I will get you my snail mail address so you can mail me some. All Best!

I had several skylights installed on my ribbed metal roof. Now I have severe leakage at one of the skylights, and I fear the others may begin leaking as well. Can someone please comment on proper installation and sealing guidelines? I can provide some digital photos of the installation if anyone can help troubleshoot the installation and the leakage issues.

I have the exact problem...I want to keep present roof because of historic accuracy..No contractors in area wants to help me restore present roof. It needs some rust removal, it think, because if I repaint it, the paint runs off with firsthard rain. I want some kind of protective paint or coating to keep it from leaking..Also the boxcut trim is deteriated, and I don't know how to restore this area...Money is also a concern.

A good cleaning of the roof, including removal of the rust, would be good preparation before using a quality primer and top coat intended for exterior metal building products. Cleaning can be done with a mixture of detergent, household bleach, water, and TSP (such as Soilax). On areas where bare metal is exposed, use a rust inhibiting primer as well. Also, as I suggested to the previous author, feel free to meail me photos at [email protected] and I can provide additional input.

When we initially built our log house, it had a re-vent system for the bathroom fixtures. This did not work as it should have, so we had to penetrate the roof and install a stack. Now, no matter what we do, when it rains heavily, the water comes in around the stack. There is a boot in place and my husband has painted the area around the stack a number of times with mastic in an effort to get it to stop, to no avail. Since we are in a rural area of N.C., it is difficult to get anyone to respond. Please help!!

I would need to know what type of roof system you have to nail the detail down however there is a rubber fashing called MasterFlash for this type of post flashing that can be done yourself. It comes with pre sized cut off rings and sits on the metal in Butyl tape and then is stich screwed to the metal but not into the deck. Remember the metal roof, structure and pipe all move and contract at differant rates. Hope this helps.

I have my house's original 85 year old metal roof mostly scraped of peeling paint and soon to be ready for repainting. I have had past problems with paint peeling too fast, and previously had red Rustoleum peel within four or five months. A friend tells me that only aluminum color paint will last well and that it has to be a covering which can expand and contract, rather than a paint, which is too rigid. I would prefer the glossy black which I had in the past, which was beautiful, but have been listening to arguments about how much more energy efficient the house would be if the roof were light. What can you tell me? The most recent things which were on the roof were a black covering, which contained asphalt, and the previous $30 a gallon Rustoleum red paint. Thanks.

You need to, by cleaning, get down to the base metal as best as possible. Subsequent coatings at this point will only adhere as well as the coatings beneath them. I suggest going to a quality paint store and using the primer and top coat they suggest for this type of application. Sherwin Williams has a primer called Pro Cryl which I have seen work well.

I just recently (yesterday) started scraping my roof, which has sporadic peeling/rusty areas. A neighbor said that with galvanized roofs, the original coating was intended for a slightly rusted roof, and that it bonds better that way. My question is if I go out and look for that kind of paint: will it bond to the paint that IS holding to the roof, and will it still peel from the spots of metal roof I've scraped that AREN'T rusty? Thanks(in advance), Dawn

Try to get back to the base metal wherever possible. Use a quality primer from a quality paint store folloed by a quality top coat.
