We are fixing to get a new metal roof on our house I was told that the washers will go bad and leak in 7-10 yrs. We heard that metal roofs should out last any shingle roofs.

A few things about the washers: Some years ago, panels were installed using nails or screws with rubber washers. These washers were directly exposed to the sun, which made them dry up and lose they're seal. The screws mostly used now are much more advanced. Some of them are different, but the below description fits most of them: Commonly hex head washers, The screw is galvanized, then painted to match the panels. It has a metal umbrella washer with a neoprene rubber seal under it. The metal washer covers the neoprene rubber seal almost completely, leaving only a thin edge exposed. This protects the rubber from the UV rays of the sun, greatly prolonging its life span. Even then, after 15-20 years its not a bad idea to have someone go up on the roof and inspect the fasteners. Replace any that have problems at that time. These type of screws have been very successful for some years now. The only time I've seen problems with them is when they they were put in too tight, too loose, or crooked. (Make sure to set the torque on the power drill.) Another thing I’ve seen is when the screws were put into green lumber that wasn’t properly cured. They loosened and had to be retightened.
