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.

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)

Built-Up Roofs (BUR)

Contractors have been producing built-up roofs for centuries, and GSM Roofing has been installing them since we started in 1946. This commercial roofing system uses multiple plies of material to create a durable, long-lasting surface you can rely on.

There are several options available when choosing your specific built-up roofing system. We’ll guide you through choices, like hot-mopped vs. cold-applied, gravel-surfaced vs. smooth-coated, and modified vs. traditional bitumen.

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.

I do not check the work. But I can say that the two men answered my question with courtesy. They assured me that the roof is in good order. And your company responded to the work order on short notice as coordination with plumber's installation was key. My association with your company has always been more than satisfactory.
