Commercial Roofing Systems We Install
The correct commercial roofing system depends on the building’s roof slope, drainage, existing construction, insulation requirements and long-term performance goals. Queen City Roofing installs several complete roofing systems for qualifying commercial and multifamily properties throughout New Hampshire.
EPDM Rubber Roofing
EPDM is a flexible synthetic rubber membrane commonly installed on flat and low-slope roofs. It is a proven roofing option for many commercial, condominium and multifamily buildings that need a durable protection.

Architectural Shingle Roofing for Commercial Buildings
Not every commercial building has a flat roof.
Queen City Roofing installs architectural asphalt-shingle roofing systems on qualifying commercial and multifamily buildings with properly sloped roofs, including condominiums, apartment buildings, churches, offices and community properties.
Architectural roof shingles also offer increased durability and wind resistance, along with up to 40yr 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.

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.
Frequently Asked Questions About Commercial
Roof Replacement
What types of commercial roofs does Queen City Roofing replace?
Queen City Roofing replaces qualifying EPDM, TPO, asphalt shingle and other commercial roofing systems on condominiums, apartment buildings, offices, retail properties and light-commercial buildings in New Hampshire.
How do I know when a commercial roof should be replaced?
Common signs may include recurring leaks, deteriorated roofing materials, separated seams, damaged flashing, trapped moisture, poor drainage, widespread surface wear or an aging roofing system. The roof should be evaluated before a complete replacement system is recommended.
Is EPDM or TPO better for a commercial building?
Neither system is automatically better for every commercial building. EPDM is a flexible synthetic rubber membrane with a long history of use on flat and low-slope roofs, while TPO is a thermoplastic membrane with heat-welded seams and is commonly chosen when a lighter, more reflective roofing surface is preferred. The better option depends on the building’s roof design, drainage, insulation, existing construction, exposure, energy goals and project budget. Queen City Roofing evaluates these conditions before recommending the roofing system that best fits the property.
Can an occupied commercial building remain open during roof replacement?
In many cases, yes. Commercial roof replacement can often be planned around normal building activity, many buildings can remain occupied during roofing work, but access, safety, noise, material staging and safety requirements must be planned carefully. Project conditions should be reviewed with the owner or property manager before installation begins.
