Our services include:

We Work With Many Types of Roofing Systems

Also known as composition roofing — It is made from fiberglass matting, followed by a layer of asphalt and topped with protective mineral granules. The newest types combine Cool Roof technology in a wide range of colors. We offer affordable basic three-tab and laminated designer styles from GAF, CertainTeed, Atlas, Tamko, Owens Corning, and others.

This is an asphalt-based system, closely related to BUR roofing and designed for low-slope or “flat” roof structures. It offers five layers of protection and low maintenance.

Sometimes called Rubber Roof, this is a membrane roofing system that offers flexibility in colder environments and sunlight reflection in the summer months, reducing cooling costs.

Thermoplastic Polyolefin is a single-ply roofing membrane that is one of the fastest-growing commercial roofing systems on the market. TPO roofing systems are made up of a single layer of synthetics and reinforcing scrim that can cover flat roofs. Want to learn more about TPO roofing? Click here to read the article.

What is the best Commercial Roofing Material for your property?

Determining the best roofing system for your property involves several factors, such as the type of business, budget, the environment, the building structure itself, and the existing roofing system. The roof must be more than merely the top of the building – it’s a system that works with your existing building structure to protect your staff, customers, tenants, and inventory.

Roof problems? Here are 5 signs to watch out for:

1. Leaks

Any water entering the building after a rainstorm could indicate that your roof has been compromised. Our team’s inspection will determine how extensive the problem is and what steps need to be taken. Leaks can also show themselves through water stains on your interior ceiling and walls.

2. Outdoor light

Sunlight should be coming through your windows, not your roof. If you can see the light coming in where it shouldn’t be, it’s time to call in the experts.

3. Sudden utility bill increases

If your HVAC providers cannot determine a reason for your heating/cooling issues, air may be leaking out through your roof, windows, or siding. Give us a call right away, and our team of experts will help track down the problem.

4. Damaged roof membrane

Bald spots on the membrane, or uplift in the membrane following a storm could indicate that your roof has been or is about to be compromised, leading to leaks and other issues. We can do a full inspection to determine where the problem lies.

5. Roof deck damage

Most roof deck damage is caused by water. Any visible wear and tear should be investigated by roofing professionals immediately to avoid more significant future problems.
