Mazzi Contractors Roofing Services

Mazzi’s roofing contractors have the knowledge and training to expertly install or repair roofs for both residential and commercial properties. Mazzi Contractors starts with a wide variety of the highest quality materials to complete each project. Quality is top priority for our contractors, both with our products and our workmanship. Product warranties range from 25 years to a lifetime and we offer a one-year guarantee on workmanship. GAF, CertainTeed and Owens Corning are three manufacturers whose products we trust.


GAF offers a broad array of environmentally friendly solutions for both residential and commercial properties. Products include reflective or “cool” roofing, re-cover roofing that helps reduce landfill waste, garden roofing, and solar roofing products in addition to traditional asphalt shingles.  

GAF recommends a six step protection process for roofs. First a leak barrier, a self-adhering waterproof membrane, helps protect areas most susceptible to damage, like the top, joints and eaves. Then a roof deck protection layer covers the whole roof area to protect from wind and other elements. Asphalt shingles are available in a wide array of colors and styles to suit homeowner preferences. Ridge vents help release damaging moisture and heat from the attic. Finally, the ridges and hips get protective ridge cap shingles that enhance the appearance of the roofs as well as help keep out wind and water.


CertainTeed has been in business for over 100 years and has earned a reputation for premier building materials. CertainTeed offers a quality line of roofing solutions for both residential and commercial buildings. The company’s architectural laminate and asphalt shingles combined with CertainTeed Ridgevents create an efficient, effective and impressive roof in a variety of style choices.

CertainTeed offers sustainable solutions as well. Solaris shingles and CoolStar commercial products were both designed to reduce carbon dioxide emissions and energy use through the use of solar reflective surfaces.

Owens Corning

Owens Corning has a three step protection system for roofs: Seal, defend and breathe. First, one of the WeatherLock water barriers acts as an additional layer of protection. Next, shingles are available in a variety of colors and styles from economy to top of the line levels. Duration Premium COOL Shingles reflect solar energy, keeping roofs and home interiors cooler and reducing energy costs. Whichever shingle type is chosen, corresponding hip and ridge shingles complement and add protection for the top and any rises on roofs. Finally, a VentSure InFlow vent at the ridge of a roof helps it breathe, reducing heat and moisture that can cause damage.  This vent is another feature that can reduce energy costs.
