Here’s the new barn roof coating in progress:
And here it’s all done!
Responding to questions: I had an aluminum roof coating applied to the barn roof. This is a coating that gives the appearance of a tin roof (it’s silvery in color) and is applied over tin to seal and protect the existing roof. Applied about every five years, it can extend the life of a tin roof for decades. Eventually, of course, you need a new roof, but if your roof is in reasonably good shape, it’s a maintenance measure to carry the roof forward in time. This roof was in pretty good shape, only required some very minor additional patching in a few places, so it’s not time for a new roof yet. The coating itself will seal pin holes in the roof. The roof was cleaned then the coating was applied with brushes and rollers. It went pretty quickly–only took about half the day. Now my barn roof is good to go!
Money could not be better spent than on saving a barn.
