Our Process:
We start by assessing and preparing your deck, replacing any damaged plywood if needed. Then, we install your chosen vinyl membrane with clean seams and precise detail—leaving you with a stylish, worry-free surface built for years of use.
Flat Roofing
SBS Modified Bitumen
SBS (Styrene-Butadiene-Styrene) is an asphalt membrane reinforced with polymers for extra flexibility. It performs especially well in climates with wide temperature swings, staying pliable in cold and stable in heat. Installed in layers—either torch-applied, self-adhered, or cold-applied—it creates a tough, redundant system. Granule-surfaced cap sheets add UV protection, giving SBS roofs excellent durability for homeowners and property managers looking for long service life.
TPO & PVC Single Ply
TPO (Thermoplastic Polyolefin) and PVC (Polyvinyl Chloride) are lightweight, reflective membranes that are hot-air welded at the seams for a watertight finish. PVC is highly resistant to chemicals and available in 60- or 80-mil reinforced sheets, while TPO is valued for its energy efficiency and “cool roof” properties. Both are great for clients who want a modern look, fast installation, and lower cooling costs, without the fire risk of torch-on systems.
EPDM Rubber
EPDM (Ethylene-Propylene-Diene Monomer) is a synthetic rubber membrane known for its flexibility and long lifespan. Available in large sheets up to 50 feet wide, it minimizes seams and adapts well to buildings that expand and contract with the seasons. Typical thicknesses are 60 or 90 mils, and its UV and ozone resistance make it a dependable choice for customers who want a straightforward, low-maintenance roof that can last 20–30 years with proper care.
Our Process
Every flat roof we build starts with inspection and design: checking slope, drainage, and structure. We then prep the deck, add insulation, and install the chosen system with precise attention to seams and flashings. Whether it’s SBS, TPO/PVC, or EPDM, the details—edges, drains, and penetrations—are where roofs succeed or fail, and that’s where we put extra care. The result is a clean, watertight roof backed by supplier warranties and decades of performance.
