Seal flat roof and garage yourself
If you are tired of shoveling gravel on the garage and firing on the burner, you can now do a simpler sealing of your flat roof. There are roof sealants that just pass on the surface. These lie like a diving suit (seamless) over the roof - flexible and dense. The gravel is then no longer needed, as these roof sealants are very UV-resistant. Gravel has only one purpose, the old seal (foil or sheets) to protect from the sun - nothing else.
