I am doing a lot of flat roof work using self-adhered granulated ruberoid: porches, additions, balconies. It is expensive, but easier to install and is in my opinion longer lasting than torch, it has a “double” protection - base + cap sheet. Besides during the installation torch becomes less flexible at some places, cause it is installed using high temperatures.And it can actually save lots of money cause you don’t have to purchase torch insurance.
Does anyone have an experience with these materials? Can self-adhered material replace smooth ruberoid both for residential and commercial roofs guarantee wise?
