Flashing Drainage Ventilation

Residential roofs and many commercial roofs are considered steep slope, possessing a grade of 25% or more. The components that make up this specific style of roof each play a crucial role in the quality and function of your roof. At Tony Newman Roofing, our technicians focus on each component and each step in the installation or repair of your steep slope roof.

Roof Structure

Your roof is framed and shaped using rafters and trusses specifically designed to support the weight and slope of your roof. This structure provides the basic support skeleton for the sheathing and covering that will protect your home or business.


The roof sheathing is comprised of the boards or decking that are affixed to the rafters to provide the base cover for the structure. It’s important that the sheathing is level and properly installed as well as protected from moisture in order to maintain its strength and integrity.

Roof Covering

Two elements comprise the roof covering – the underlayments and the shingles. Underlayments may be felt or synthetic and provide the water-resistant barrier needed to protect the sheathing. High quality asphalt shingles provide the final layer of protection for your home or business. Options include strip shingles, dimensional shingles, and premium shingles from Owens Corning and CertainTeed, all available in a broad range of colors and styles to enhance any structure, including homes, garages, sheds, retail establishments and office buildings.


Along with the underlayment and shingles, flashing is needed to protect the most vulnerable areas of your roof. Typically, this is sheet metal or another thin material that is installed at the roof joints, including along walls, valleys, chimneys, and other roof pipes. Anywhere your shingles butt up against something, flashing is needed to seal that joint and prevent moisture seepage.


Your steep slope roof is designed to include features that will help it shed water, diverting it away from joints and ultimately off the roof. This system will include the specific slope and shape of your roof structure as well as drains, gutters, and downspouts to take the water off the roof and away from the structure.

Hip and ridge shingles are the final portions of roof construction, completing and protecting the junctions of two roof slopes, with the ridge being the steepest junction on the roof. These additions are designed to both finish and complement your roof shingles and the ultimate look of your roof.


Your roof ventilation system is critical to maximizing the life of your roof. A properly designed and installed attic and roof ventilation system allows a continuous flow of outside air through the attic, providing a more consistent temperature and moisture level for your roofing components. Ventilation will include air intake vents in the eaves with either a ridge vent or an exhaust fan installed near the ridge.
