GAF Master Elite® • Owens Corning Platinum Preferred • CertainTeed ShingleMaster™ • Family-Owned • Fully Insured • Financing Available

Queen City Roofing provides flat roofing and low-slope roof replacement for porches, additions, garages, sheds, commercial buildings and other roof areas where traditional asphalt shingles may not be appropriate. Depending on the project, roofing options may include EPDM rubber roofing, TPO membrane roofing and rolled roofing systems designed for low-slope applications.

What Is Flat Roofing and Low-Slope Roofing?

Flat and low-slope roofs are roof areas with very little pitch, making them unsuitable for many traditional asphalt shingle installations. These roof sections require materials and installation methods designed to manage water and protect the structure at lower slopes.

Common low-slope roofing systems may include EPDM rubber membrane, TPO membrane and rolled roofing products depending on the roof design, building type and project requirements.

Queen City Roofing installs flat and low-slope roofing systems on residential and commercial properties throughout New Hampshire, including porches, additions, garages, sheds, multifamily buildings and commercial roof areas.

Where Is Flat and Low-Slope Roofing Commonly Used?

Flat and low-slope roofing is commonly found on both residential and commercial properties.

Typical residential applications may include porch roofs, additions, dormers, garages, sheds and other roof sections with limited pitch. Commercial applications may include offices, retail buildings, condominium properties, apartment buildings and other low-slope facilities.

Because these roof areas do not shed water the same way as steep-slope shingle roofs, the roofing material and installation method must be selected specifically for the roof design.

Choosing the Right Roofing System for a Low-Slope Roof

Not every flat or low-slope roof should use the same roofing material. The best option depends on the roof pitch, size, drainage, building use, existing roof condition and how the roof area connects to the rest of the structure.

Queen City Roofing evaluates each low-slope roof area before recommending a system. Depending on the project, that may include EPDM rubber roofing, TPO membrane roofing or rolled roofing for certain smaller residential applications.

Our goal is to match the roofing system to the actual conditions of the property rather than force one material onto every low-slope roof.
