I read on a post here that a shingled roof on a coop will be hot regardless of how light the shingles are. Unfortunately, we will need to use shingles to control costs of the coop because we already have the shingles left over from roofing the house a few years ago. We checked prices on various roof options and they all seem to creep outside our budget. The entire coop is almost totally free of cost so far with the exception of the fencing for the run and the posts for the fencing. So here's my question: Is it possible to put something called "Cool Seal" over the shingles to cut down on heat absorption? This is a product frequently used (and I think intended for) Mobile home roofs as an insulating factor for heat control externally as well as holding heat inside during winter. The product has sort of a roofing tar consistency but dries pretty much like a hard rubber if I understand about it correctly. It lasts many years. The cost is reasonable for the smallest quantity they have. Our coop roof is only 6'x6'. Does anyone know anything about the possibilities in doing this? Thanks so much for any info you might provide.
