Re-coloring flat, tarpaper roof; sealing
Hello, all! I apologize that this post keeps arriving at the forum with no formatting. Yes, I DO know how to use the Hard Return, but they don't seem to be effective here. I'm sometimes handy around the house, but some projects give me pause. This is one, so I'd like some input. Here in Southern California in the summer, we get a LOT of sunlight, and on our slanted flat roof (goes to a drain in one corner; about 10 degrees) the tarpaper and tar job is beginning to leak a little. House is old for U.S., built ~1924. There is no easy way to insulate the interior of the second floor ceiling from the heat transfer, as the "attic" is about 14" high. But I have long thought that coloring the roof either white or with some aluminum-paint color would alleviate much of the heat problems we have upstairs in the summer. Looking at the products at HD, it looks like some of them also would seal the roof, and that this would be a doable DIY project for a few hundred dollars. Obviously a lighter color would help. And it could even be done with house paint, if I weren't worried about the following year or so. But am I right? Are there DIY-grade products that would accomplish both the above goals: seal the roof and prevent heat transfer? Roof is ~1,000 square feet. Thanks in advance. Don.
