Commercial Property Roofing Solutions
As detailed below, we offer three roofing solutions for commercial properties. Talk with our certified roof installers to determine which is best for your needs and budget.

Architectural Roof Shingles for Commercial Buildings
Architectural roof shingles (also known as dimensional or laminated shingles) are a durable and aesthetically pleasing solution for commercial buildings with sloped roofs—including churches, condos, apartment complexes, law offices, etc. Unlike three-tab shingles, they can mimic more sophisticated roofing styles, including shake, tile, or slate. Architectural roof shingles also offer increased durability and wind resistance, along with longer warranties. We install the industry’s leading roofing brands to enhance your building’s curb appeal while providing superior protection from New Hampshire’s harshest elements.

EDPM/Rubber Roofing for Commercial Buildings
EPDM (Ethylene Propylene Diene Monomer) roofing, or Rubber Roofing, is another membrane ideal for flat or low-slope commercial buildings. It is very durable and flexible, making it an excellent choice for buildings with complex roof shapes. EPDM performs very well in extreme temperatures and is resistant to UV rays. It has been around longer than TPO and is known to last upwards of 50 years, offering leak-proof protection in the harshest climates.
Ideal for Flat or Low-slope Buildings
Flexible for Complex Roof Shapes
Temperature and UV-resistant
Lasts up to 50 Years

TPO Roofing for Commercial Buildings
TPO (Thermoplastic Polyolefin) is a single-ply roofing membrane made from a blend of rubber, plastic, and fillers. It is ideal for flat or low-slope commercial properties, such as office buildings, retail spaces, warehouses, and industrial complexes. Attached with mechanical fasteners, adhesives, and other heat welding methods, it provides a puncture-resistant, watertight seal around the roof and penetrations (openings for pipes, vents, cables, or other structural elements). The material’s light, reflective surface improves energy efficiency by reducing heat absorption.

FAQ's
If your roof is getting up there in age or showing obvious signs of trouble—including leaks in the walls or ceilings or missing shingles or roofing materials—give us a call so we can take a look at it. The only way to know if your commercial roof needs replacement or repairs is to have an inspection by an experienced, certified roofing contractor.
The cost of a commercial roof will vary according to a variety of factors, including:
-
Size of the Roof
-
Condition of the Subroof
-
Insulation Requirements
-
Number of Penetrations ((openings for pipes, vents, cables, or other structural elements)
-
Type of Material Used (TPO, EPDM, Architectural Shingles)
Our experts will provide an open and honest assessment of the work required so we can help you determine the best solution for your needs and budget.-
It really depends on the type of materials used, the quality of your initial installation, and the extent of the damage. Please contact us to schedule a free roof inspection with one of our roof technicians. Once we’ve assessed the overall condition of your commercial roof, we can discuss your options.
A well-maintained, professionally installed commercial roofing system should be expected to last at least 30 years. As with determining cost, a number of factors are involved in projecting the expected longevity of a commercial roofing system, including the type of materials used, ongoing maintenance, weather conditions, and the quality of installation. Having this information will enable us to advise you on what you can expect from your new commercial roof.
Again, many of the factors noted above, along with local weather conditions, can determine how long it will take to complete your commercial roof installation. You will receive a projected time estimate before our work begins.
