I live in Florida and have a house with a low sloped roof, and also sections of flat roof covering the car port/utility room/porch. The sloped part of the roof is shingled, which I later found out from a roofer was done incorrectly since the slop of the roof was not high enough for shingles.
So far it's been holding up alright although it's starting to show signs of age. I had to spread a patch over a section of shingles to stop a leak which has worked very well. I'm also getting a low spot in the flat roof above the porch which is ponding water, just the other day I removed probably 50 pounds worth of loose granules in the area it was ponding. I'm going to be sweeping as much of the loose granules off as I can so they don't hold any moisture.
I probably need a new roof but in no way can afford it. I was hoping to extend the life of the roof a bit by applying an Acrylic Latex Silicone Coating / Sealer coating that sells at Home depot. For the ponding issue I was thinking of using something like this to help http://elastek.com/products/basecoat...uddle-plaster/
Now I know this would only be temporary, I'm just trying to buy some time until I can afford a new roof. I was thinking the coating might actually help seal the shingles since they shouldn't even be on my roof to begin with. Also the reflective qualities of the coating should help significantly reduce roof temps and reduce energy costs.
But the problem is I'm not finding a whole lot of info on these coatings since they are fairly new to the DIY market. Would it be worthwhile investment, and be able to extend the life of my roof for at least a few years?
