PetersenDean understands that quality products—like superior workmanship—are key to building the best roofs. Having built more than a million roofs over three decades, we’ve come to know which products work best and which offer lasting value.

We are also keenly aware of the need to build energy efficiency into our installations. We offer products and know-how to help our contractor partners construct facilities that can not only meet, but exceed, the stiffest state energy efficiency standards for new construction.

PetersenDean continues to be National Housing Quality (NHQ) Builder and Trade Contractor-certified, evidence of our commitment to investing in the training, equipment, policies, and procedures that guarantee superior workmanship.

Our crews are certified to install the following standard roofing systems:

	Built-Up For flat or low-slope rooflines, built-up systems require quality manufactured roofing products, the right specifications and asphalt temperature to ensure the roof is built to last.
	Single-Ply These non-asphalt based roofing membranes meet “cool roof” standards, reflecting the sun’s rays and helping to you maintain cooler interior temperatures. Constructed from ethylene propylene rubber, they are designed to combine the durability of rubber with the proven performance of hot-air weldable seams. They have been tested as having excellent resistance to ozone, are algae-resistant, environmentally friendly, and safe to install.
	Metal A durable and energy-efficient roofing option, metal roofs carry warranties of up to 30 years. PetersenDean offers standing seam and tile metal roofing options for all roof types.
	Tile PetersenDean ‘s reputation for our skillful installation of concrete, clay and slate tile roofing systems extends nationwide.
	Composition Shingle For sloped roofs, composition shingles are an economical and attractive option. PetersenDean has installed more than 100,000 composition roofs since 1984 and carries the widest selection of products available for this roof type.
	LEED-certified PetersenDean supplies roofing materials that meet Title 24 and LEED certification standards. Other roofing materials—installed with insulation and ventilation systems—can improve a building’s energy efficiency by reducing the power needed to heat and cool it.
