Never heard of a "1/2 lap" granulated surface. The granules protect
the cap sheet from UV damage, so you'd need to have granules over
the entire exposed surface. Sounds like the existing roofing was
installed wrong?

It is known as a double coverage roll roofing. The granules are
exposed for 17". No granules on 19", this is where solid coverage of
adhesive goes. An outdated roofing material which is still being sold.

Thanks - that is interesting to know about. Was it designed for a
one-ply installation, or was it used over a base sheet?

Forms it's own base sheet as 1/2 is not granulated.

You're way too late. **13** years ago, Travis was abducted by giant alien mutant gerbils from outerspace. The took him into their flying saucer and he hasn't been seen since. His 237 normal Earth Gerbils really miss him. It's been theorized by The Air Force that the giant alien mutant gerbils were angry that Travis was holding so many of their smaller brethren and put him in a cage to punish him. ヽ(ヅ)ノ
