I need to replace a small section of flat roof - space is slightly smaller than 12’x8’. It currently has an old rolled roof. One roofer recommends Polyglass and speaks very highly of it. He does not recommend a rolled roof at all. A second roofing company seemed unfamiliar with Polyglass and spoke very highly of rolled roofs. I know nothing about roofs and am trying to find out the pros/cons of each to make an informed decision. I have a price estimate for the Polyglass roof and am still waiting on a price for the rolled roof.
One question I have about Polyglass is the heat resistance it allows. The company recommending the rolled roof spoke about installing a light colored roof to help reflect sunlight. This roof is over a small addition that does not have a true foundation. Even with insulated curtains, it gets very hot in the summer, so anything to help lower the temperature is a plus in my book. But I don’t want to make a decision based solely on that.
Any advice is welcome - I am very unfamiliar with roofing terms, so please explain what they mean to me as you use them. My home is in the Boston area if that helps at all. Thanks!
