Flat Roofing for Commercial Properties

If your property or commercial building has a flat roof, you’ve found the right roofing company. Adam Quenneville Roofing & Siding has 20+ years of experience as a flat roof specialist. We offer a wide range of flat roof options from single ply flat roofing membranes to commercial PVC flat roof systems. We have partnered with professional manufacturers of flat roofing materials such as Duro-last® and ASTEC®, two companies that offer the finest waterproofing systems available. We are trained by these companies to install, repair, and maintain durable solutions for the company you manage.

  1.  Duro-Last® – Adam Quenneville Roofing & Siding is an authorized contractor for low-maintenance Duro-Last commercial roofing systems, and we have proudly received awards from Duro-Last for our quality installation. The custom-fabricated, single-ply PVC Duro-Last system is ideal for any flat or low-sloped application. It is extremely durable and easily installed without disrupting building operations. The Duro-Last Roofing System is watertight, highly reflective, resistant to chemicals, fire, high winds, and grease, which is why it is installed on 3,000 restaurants a year. Since 1978, billions of square feet of Duro-Last membrane have been installed throughout North America, and because Duro-Last is manufactured in Ludlow, MA, it’s always in good supply. Duro-Last offers best-in-class warranties that includes interior, prefabricated flashings, a Quality Assurance department, problem-solving products, and a commitment to stand by every square foot.
  2. ASTEC® – Flat roof restoration can save you 50% over the price of replacement. ASTEC’s Multi-Layer Roof Restoration System can be installed over (and bonded directly) to your existing roofing material whether it’s modbit, asphalt, TPO, EPDM or metal. Since 1986, the ASTEC company has been dedicated to the production of high quality, environmentally friendly, fluid-applied membranes and systems. ASTEC can solve leakage problems, improve the appearance of commercial buildings, and help you to save energy. Adam Quenneville Roofing & Siding has partnered with the ASTEC company because of its commitment to the restoration of existing roofs with weather-tight technology. We are pleased to offer you ASTEC Re-Ply Roofing Systems so you can Re-Ply your flat roof instead of replacing it. ASTEC will help your roof remain tough, flexible, and waterproof even in extreme weather conditions.

Benefits Of Flat Roofing

There are many benefits to flat roofing for commercial properties. Flat roofs are easier to install and maintain than pitched roofs, and they can also be more cost-effective. Additionally, flat roofs offer a number of other advantages, including:

1. Increased Energy Efficiency: Flat roofs are less likely to experience leaks and drafts, which can lead to higher energy bills. They also reflect heat better than pitched roofs, helping to keep your home or office cooler in the summer months.

2. Greater Safety: Flat roofs are less likely to collapse in heavy winds or during earthquakes, making them a safer option for both homeowners and businesses.

3. Enhanced Aesthetics: Flat roofs can give your property a modern look, and they can be customized with a variety of finishes and colors to suit your taste.

4. easier to Install: Flat roofs are typically much easier to install than pitched roofs, which can save you time and money during the construction process.

5. Greater Flexibility: Flat roofs offer more flexibility when it comes to design and layout. They can be used for a variety of different purposes, including solar panels, rooftop gardens, and outdoor seating areas.

If you’re considering a new roof for your business, be sure to ask your contractor about the benefits of flat roofing. It may be the perfect solution for your needs!


Over time, all roofs wear out and will eventually need to be replaced. If you wait too long to repair or replace the roof, you can end up with leaks and expensive damage. Replacing the roof too soon (if you’re content with the condition and look of your roof) can be a waste of money. Many minor problems can simply be repaired. It’s important to be aware of common roofing problems and which ones should be dealt with right away.

As experienced professionals, we at Adam Quenneville Roofing & Siding can assess the condition of your roof for any early signs of roof failure. Contact us today for a free cost estimate for your property.
