My 2 car garage has a flat roof. When I bought the house in '96 it was tar and gravel. About 10 years ago we ripped off the old - roof plywood and all - and replaced with peel and stick roll roofing.
Been toying around with adding climate control in there but not quite ready for that now. In the meantime it gets hot inside. I was looking at various roof treatments to help with temp. modification and found one that had really good reviews and sounded like the perfect material for my application.
It's by Black Jack and is a white silicone coating material. I bought a 5 gal. container of it from Lowes about a month or so ago so am now getting ready to do the job.
This morning, in preparation, I power washed the roof. I didn't realize how much crud had accumulated in the 10 years it's been up! Thanks goodness I had my Ryobi surface cleaner attachment which saved me a TON of time and effort. It still took a while to do but I feel much better knowing I went the extra mile to give the coating the best chance for adhesion and durability over time.
I will post followup pics after the coating is done. Not sure when I will do that - maybe the weekend. Maybe tomorrow. Depends on the weather.
