Industry-Trusted Methods to Waterproof Your Roof

Residential flat roofs need dependable protection from rain, ice, and snow year-round. Magnum Commercial offers our clients three main methods to waterproof their roofs. We provide roof coating or liquid waterproofing, single-ply membrane roofing in the forms of EPDM and TPO systems, and reinforced bitumen membranes, otherwise known as modified bitumen. Below are descriptions of three of these options:

Modified Bitumen

For a low-slope roof, modified bitumen systems provide durability and weather resistance. We can install these systems using asphalts, the common torch method, or cold adhesives. Our team applies standard styrene butadiene styrene (SBS) modified bitumen roofing systems in rolls as two-ply systems overlapping the edge of the previous roll.

EPDM Single Layer Roofs

Roofing companies commonly use ethylene propylene diene monomer (EPDM) roofing systems’ single-ply material on commercial buildings. We apply EPDM roofing systems in large rolls, varying in thickness and size, and we fully adhere, mechanically fasten, or ballast them. After applying the material to a roof, we use seam tape to seal the sheets’ seems together to create a waterproof bond.

TPO Single Layer Roofs

If you want an environmentally friendly low slope single-ply roof, we recommend a thermoplastic polyolefin (TPO) roofing system. TPO is applied in large rolls with various thickness and size options, and we can fully ballast, adhere, or mechanically fasten it. After attaching the rolls to the roof, we hot air-weld the seams of the membrane, forming a very strong waterproof bond between the sheets.
