In a perfect world, one roofing material would work on any roof in any climate. Unfortunately, APP-modified bitumen, like all roofing materials, isn’t a one-size-fits-all solution. If your roof doesn’t have a proper draining system, this roofing material can deteriorate quickly, as standing water wears down the material. In addition, APP-modified bitumen isn’t ideal for roofs that experience frequent foot traffic. So if your building has a rooftop patio, consider looking for a different roofing material. Another drawback of APP-modified bitumen is that it can attract heat and raise cooling costs. However, you can avoid this problem by asking your contractor to apply granules or a reflective coating on top of the modified bitumen.
