Polymeric membranes are extremely versatile, and they are a perfect choice for flat roofs. They can be used on new constructions, renovations, or to repair roofing. This popular synthetic material can provide long-lasting waterproofing that will keep roofing in excellent condition for years. Polymeric membranes can last for up to 25 years, plus they’re fire-resistant and environmentally friendly. These are the easiest (and most inexpensive) option for waterproofing pitched roofs, including slate, tile, and metal roofs. Most of the time, waterproofing foil is used for insulation in attics and lofts along with mineral wool and polystrene.
