WHAT OUR CUSTOMERS SAY

FREQUENTLY ASKED QUESTIONS

Do I have to remove my current commercial roof or can I re-roof it?

If your building roof is in good condition and hasn’t been re-roofed before, there’s a strong possibility you can save money by adding a new roof without taking the old one off.
Sadly, there are some situations where a roof tear-off is necessary:

  • Currently, your building has two roofs: Commercial structures are only allowed to have two layers of roofing, per the law. This is done to avoid putting undue strain on the building’s structural integrity.
  • Your building’s roof is unstable. Your contractor will need to remove the current roof in order to install a new, functional roof if your roof is damaged, wet, or unstable.
How can I determine whether my company needs a new roof?

To evaluate the status of your current roof, our specialists will conduct a free roof assessment. Internal deterioration, such as mold or roof leaks, are signs that your business roof may be unstable and require replacement.

When should I plan my roof inspection?

Contractors start roofing projects as soon as the weather warms up. It’s best to get in touch with a contractor in the late summer to arrange a survey for when spring finally arrives in your area. They can then begin working on your job as soon as the roofing season begins.

What will the cost of my new roof be?

The difficulties specific to each situation are what cause the pricing to change. We are in direct competition with all the reliable and effective commercial roofing solutions. The cost of your new business roof depends on a variety of things.

Among these elements are:

  • The Size of your roof
  • The State of the current roof
  • Roof Access
  • Insulation Strategy
  • Membrane Selection
  • Installation Selection
  • Roof Punctures
  • The Warranty Type

After one of our roofing specialists conducts a free roof evaluation and generates a roof survey report for your facility, we can assist you in developing a budget.

How long will my commercial roofing system likely last?

Your commercial’s longevity will rely on a variety of elements, including the type of roof and the weather.

The following averages apply to typical roof systems:

  • Spray Polyurethane Foam: 30 to 50 Years
  • Built-Up: 10 to 15 Years
  • Metal: 30 to 45 Years
  • Single-Ply Membrane TPO: 15 to 20 Years
  • Single-Ply Membrane EPDM: 20 to 25 Years

Meet The Owner

“GM Systems was founded in 1999 by Greg Stierwalt, in a bid to address a need by providing an affordable solution to fix leaking or damaged roofs. Leveraging on elastomeric roof coatings, we currently specialize in the application of high solids silicone roof coatings as well as the installation of single ply/membrane roofing systems.

Thriving under Greg’s leadership, we now have a full suite of products to meet any need a commercial customer may require whether it be the waterproofing/sealing and repair of an existing roof or a new construction project. In this sector, having a niche business presents a number of difficulties as well as opportunities; yet, in the end, the company must still perform exceptionally well and provide products of the highest possible quality in order to be successful.

Greg attributes a significant portion of the company’s accomplishments to both the team at GM Systems and years of industry experience that has made possible the level of quality commercial roofing service GM Systems offers.
