I have a “modern” flat roof house that is about to be reroofed with a built up modified. THe old skylights are the plastic bubble type and very loud when it rains. For better insulation from the heat (Florida) we have chosen glass for replacement. THe concern however is the need to install them at a pitch which is different from the plastic which just laid flat ontop of a built up curb- from the inside, the drywall extends up to meet the top of the skylight. For the glass skylights, will we need to cut the existing drywall to an angle or Build an angle up and what pitch is recommended?

According to Velux, if your roof angle is less than 15 degrees, you'll need to install one of their curbs for proper rain runoff. Their curbs are well-built, fit perfectly, and relatively inexpensive.
*ElinorC.H. is right, Velux does make a good product. The other option you may consider, is finding a custom built unit by a local glass/skylight contractor. I'm a roofer and can easily build a flashing that sets flat on a curb and is watertight. You just add the glass. No I'm not looking for work, but someone in your area may be.Good luckTerry
