Get to Know Your Roof
Roof Decking
- Definition: The roof deck is the base layer of the roof structure, typically made of plywood or oriented strand board (OSB).
- Function: It provides a stable substrate for the roofing materials and supports the weight of the roof system.
Underlayment
- Definition: Underlayment is a waterproof or water-resistant barrier installed directly onto the roof deck before the main roofing material.
- Function: It provides an additional layer of protection against moisture infiltration and helps to extend the lifespan of the roof.
Roof Material
Types: Various materials are used for roofing, including:
- Asphalt Shingles: Popular for their affordability, versatility, and ease of
installation. - Metal Roofing: Durable, long-lasting, and available in different styles such as standing seam or corrugated metal.
- Wood Shakes or Shingles: Natural and aesthetically pleasing, often cedar or redwood.
- Tile Roofing: Clay or concrete tiles that offer durability and architectural appeal.
- Slate Roofing: Natural slate tiles known for their longevity and distinctive appearance.
Flashing
- Definition: Flashing consists of thin strips of metal or other waterproof material installed around roof penetrations and edges.
- Function: It prevents water from seeping into vulnerable areas, such as valleys, chimneys, vents, skylights, and edges.
Gutters and Downspouts
- Definition: Gutters are channels attached along the roof line that collect rainwater and direct it away from the building.
- Downspouts: Vertical pipes that carry water from the gutters down to the ground or drainage system.
- Function: They protect the building's foundation and prevent water damage to the
exterior walls and landscaping.
Ventilation
- Definition: Ventilation components include intake vents (often located at the eaves or soffits) and exhaust vents (such as ridge vents or roof turbines).
- Function: Proper ventilation allows air to circulate i n the attic space, reducing heat buildup in summer and moisture buildup in winter, which can prolong the life of the roof and prevent issues like mold or ice dams.
Ridge Caps
- Definition: Ridge caps are the finishing touch on a roof, covering the peak where two slopes meet.
- Function: They provide a waterproof barrier and enhance the appearance of the roof while protecting the ridge vent from weather elements.
Insulation
- Definition: Insulation is installed in the attic space or between rafters to provide thermal resistance and improve energy efficiency.
- Function: It helps maintain a consistent indoor temperature, reducing heating and cooling costs and preventing condensation within the roofing system.
