Regular inspections, repairs, and replacements of failing systems are essential if you're a commercial or industrial property owner. This can help maintain your building's structure and integrity — reducing the risk of costly damage.

Whether your business uses flat, low-sloped, or steep-sloped roofs — whatever the installation style, we have the knowledge and experience to take care of it.

If You Have A Commercial Roof, Let Us Look At It


TPO roofs are made of two layers of material — the TPO membrane and reinforcement mesh. The TPO (thermoplastic polyolefin) is a product of synthetic materials engineered to last longer than traditional roofing materials. The reinforcement mesh strengthens the TPO, which brings a durability factor to the roofing system and helps keep the weight to a minimum.


EPDM membrane, also known as Ethylene Propylene Diene Monomer, is used in different applications, from swimming pool roofs to industrial roofs — and everything in between. High-quality rubber roofing systems protect many buildings, including schools, churches, retail stores, auto dealerships, and manufacturing facilities.

Modified Bitumen

Modified Bitumen is an asphalt-based, close cousin of the Built-up-Roof (BUR) designed for low-slope or "flat" roof structures. Modified Bitumen has been modified to include additional materials that make this roofing option more resilient. This is why it's sometimes called Reinforced Asphalt Roofing.
