<div dir="auto">You have to completely seal the roof. There's no ventilation so any water that gets in has no place to go to evaporate.</div><div dir="auto"><br></div><div dir="auto">It's apparently more common in Texas and Florida than here in the Chicago area, but it's catching on. Studies show only a tiny increase in roof temp and a tiny loss of shingle life without ventilation. Shingle manufacturers vary in their responses, with some okaying the practice and some refusing to warrantee any roof so installed, but shingle warrantees are a joke anyway, so this is just one more way to get a claim refused. I'm using 100% coverage of high temp ice and water shield.</div><div dir='auto'><br></div>

<div dir="auto">I used my cheap Horrible Freight multi tool with the plain scraping</div>

<div dir="auto">PS 7 to 8 inches of closed cell foam under the roof is pretty much a</div>
