when is the best time of year to paint a standing seam roof? we have a standing seam roof that is about 20 years old. we need to have it primed and painted due to some surface rust. the painter has been very busy and is telling us it will be at least the second week of Oct before he can get to the job. the roof stays damp from morning dew until late morning at least and i am concerned about moisture/dew settling on the roof before the paint has had enough time to dry/cure before sunset. someone told me it is too late in the season to have it painted and we need to wait until next summer so the hot sun will dry the aluminum out prior to painting and also we will have a longer period of daylight to allow proper dry/cure time and less chance of a heavy dew on the roof overnight. it kind of seems like a no brainer and we tend to agree with this person to not have it painted but my painter says it will be OK... can you give me some advice on this??

Lisa, i would agree that it is best to wait until next year to repaint the roof. I have a question. You said that there is surface rust yet you refer to it as aluminum. Make sure that you are seeing surface rust and not some staining from debris. If it is staining you might be better off cleaning rather than repainting. Do you know what type of paint system you have?

oops...i mistyped! it should have read "the hot sun will dry the ROOF out prior to painting" they will be using an aluminum paint. (that's what happens when i try to re-write my sentences and then don't proof read well enough!) i do not know what kind of paint system will be used. i spoke with another painter yesterday and he is telling me that he paints metal roofs all the time and the paint he uses will dry enough to withstand overnight dew and as long as we don't have a heavy rain for 2 days after painting it will be fine. and whatever it is he uses doesn't require a primer. i'm really confused!

Lisa, I am going to turn you over to someone who is very knowledgeable about repainting of metal roofs. His name is Harold Schroth and he can be reached at [email protected] It would be helpful to know who the manufacturer of the panels was; that might determine the type of paint system. let me know if there is anything else we can do for you.

We have recently moved into a house that was built about 10 years ago. The owners used a permacooper standing metal roof above 2 bay windows as well as on front porch. It was clearly an added detail as the main roof is shingles. It's in great shape no rust or damages. The only problem is I don't like the "fake" cooper color. I'm wanting to paint it and have heard mixed reviews. Would love some advice. Thanks

The best time of the year to re-paint seam roof is obviously in the months with the least annual rainfall. Pick a day or two where no rain is expected – this will give you enough time to prepare the surface appropriately and allow the roof paint to dry properly between coats.

Claire, this probably is repaint able with a quality paint system intended for this purpose. Go to a quality store such as Sherwin Williams and request their suggestion. You will want to clean the roofs, apply primer, allow it to dry, and apply top coat. Please keep in mind you will be voiding any warranty on the original product probably.
