Roof Replacement

Re-roofing a commercial building requires a lot of planning. In many cases, operations need to continue, so it’s up to the contractor to keep noise, fumes, dust, and debris contained. And, of course, that contractor should also show great concern for the safety of everyone on site.

What is the best option for your roof replacement? The short answer is: “the one that best suits your needs and your budget.” The longer answer is: “let’s talk.” With so many options available for re-roofing, you don’t have to stick with the same type of roofing you have now.

Green Roofs

Green-roof technology covers a wide range of systems, including:

Cool roofs
UV-reflective roof coatings
Vegetative roofs
Daylighting
Rainwater-harvest roofs
Solar roofs

Each one works to reduce energy consumption and costs, reduce carbon footprints, and contribute to a more-sustainable planet.

There might be rebates if you opt to install a commercial green roof — either on a newly constructed building or as a replacement. We can help with this process, and we can assist you in accumulating and recording LEED (Leadership in Energy and Environmental Design) points to earn a Certified, Silver, Gold, or Platinum rating.

Even if you’re new to green roofs, our versatile roofing professionals are ready to discuss the advantages and drawbacks of each type to help you find a roof you can feel good about.

Single-Ply Roofs

TPO, EPDM, and PVC each stand up to a different kind of exposure, and the right membrane for a warehouse is not the right one for a roof with kitchen exhaust on it. Our single-ply roofing page explains how we choose the membrane, the thickness, the attachment method, and the insulation under it, with the TE Connectivity, Wilson School District, and Franklin & Marshall dining hall projects as examples.

While helping you select your particular single-ply system, we will go over options, like:

Color (black or white)
Seam technology (heat-welded or glued)
Attachment method (mechanical or adhered)
Type of material (EPDM, TPO, or PVC)

Roof Coating

If you want to extend the life of your low-slope roof, reduce energy consumption and costs, or improve its appearance, look to the roof coating options offered by GSM Roofing.

White roof coatings reflect the sun’s rays, helping to keep buildings cool in the summer and reduce damage caused by UV light. The diminished need for cooling will reduce costs, and it will also ease the load on your HVAC system.
