i bought an old house with small, decorative tin shingle roof on it....the house does not leak, but the tins are beginning to rust and need painting....any tips on what to do? which paint to use? what prep i need to do?
I resently repainted the tin roof on my Gothic style farm house. (very steep pitch) First, I power-washed the complete roof with a 2500 psi washer. I did scrub some areas with a stiff brush and warm sudsy water, the section under a tree. I purchased the best paint I could find, I didn't want to do this again. Benjamin Moore has a paint formulated for metal. I applied two coats with a roller, using a brush where necessary. Be careful, I customized a wood ladder to have legs to go over the top of the roof and wore a saftey harness.
