I live in an old farm house that has one section of fairly flat roof, it
only falls one foot for twelve feet of run. About every third year I have to
haul a 5-gallon bucket of roof sealant up there and recoat the area. I had a
roofer look at it and he said it's too shallow a pitch for roll roofing,
sealant is the best way to go..
My question is whether sprinkling a layer of sand on the newly spread roof
sealant would give me another year or so of use out of it. I thought the
sand might dissipate some of the force of the rain and reflect some of the
sunlight. Or I could use gravel, if that would be better. Or spread roof
aluminizer on it after it dries. Any opinions on this?
