What is APP modified Bitumen?
APP-modified bitumen is a roofing membrane. Our team of expert contractors typically applies these membranes to asphalt with a torch.
You might be asking yourself how waterproofing works. The process looks similar to mopping, as we must spread the membrane across all sections of the roof. Once applied, you can choose to leave the roof’s surface smooth or add granules.
Depending on the weather you live in, our team may highly recommend granules. Why? Granules can help keep your building cool if you live in an area that experiences hot weather.

Bonding Strength- The existence of different types of reinforcing layers, increases it’s tenacity and stability against fatigue and rupture forces.
Drying Time- You may be wondering, how long does waterproofing take. One layer of liquid waterproofing membrane usually takes 2 hours to dry enough before the next layer can be applied. However, while it only takes a few hours for the liquid waterproofing membrane to get dry to the touch, it can take up to 24 hours for liquid waterproofing membranes to cure completely.
These roofs rarely leak- APP-modified bitumen roofs rarely leak because they don’t have seams, making this material a great waterproof roofing option. The material is also very flexible, so it is unlikely that a hail storm will leave cracks, dents, or other damage.
