Forum Title: skylight installation removing roofing
I'm getting ready to install a small skylight on a 16 degree roof, appx 22 1/2 square. its a velux self flashing unit. Couple of quick questions. i saw a video on the internet where they just cut the rough openinng right through the asphalt roof shingles. They don't remove any shingles first. Seems like it would work, then lift up the edges and slide the rubber flashing under the shingles? secondly do you put any adhesive caulk on the underside of shingles that rest on rubber flashing.?

I presume you mean triple track storms? Heat can build up between the storms and the new windows which can cause issues. Warping and seal failure for instance. If you want to keep them, they should be opened enuf in the hotter times to vent air, which kind of defeats the purpose of keeping them. Yes, they can add a bit of efficiency (not R value, thats for insulation), but they can also trap moisture and cause problems with you new windows. May also void your warranty with the replacement window manufacturer.

What happened to your Velux installation instructions? Anything on a roof can leak--skylights are the best at it. Have fun..............................
