Discuss Built Up Roofing With Your Flat Roofer In Clinton Ia
BUR or built up roof is made of layers of liquid tar or asphalt or tar saturated paper. The materials are layered in crisscross position over one another in multiple layers until the required number of layers has been completed. The roof material is alternated with the hot tar and with layer of smooth river stone. Gravel is fire retardant material and is also visually appealing in the windows and decks overlooking the roof. BUR roof is the cheapest of the roof type for flat roofs. The main disadvantage in working with these roofs is that because of the material used, they tend to be quite heavy and require the strengthening of the joist. The smell of tar is quite strong and these roofs can get messy to install. Also, you will need professionals for installation of these roofs.

Single ply roofs are made of single roof membrane which consists of a waterproof material with a weathering surface. These roofs are much lighter than BUR roofs and because of a single membrane are thinner too. Average thickness range from 45-90 mil.

EPDM roofing, TPO roofs and PVC roofing are the most commonly used single ply roofs. EPDM uses adhesives to keep the seams together and make it water proof. EPDM rubber roof comes with no water ponding warranty and require maintenance after 7-10 years on the roof. It has a very competitive pricing and provides immense ease of installation.
