Anyone who has noticed different home styles would know that roof designs can become complex. You may not want a career in construction, but it’s imperative to understand the parts of a standard roof to care for it properly. The more you know about it, the better you can anticipate issues and avoid leaks.

As a credentialed roofing contractor, AIC Roofing and Construction sheds light on the basic sloped roof build:

Rafters

Rafters make up the framework of your roof. In a conventional installation, rafters are nailed on both sides of the ridge at the top and rest on the exterior walls at the bottom. Although they need to align, some pairs of rafters aren’t directly opposite one another to make room for other components like vents.

Decking Boards

These pieces of plywood (or sometimes a different material) provide a flat surface on which everything is laid. Along with the rafters, AIC Roofing and Construction, Inc. agrees that they represent the foundation of the roofing system.

Fascia Boards and Soffits

The fascia is every horizontal piece of material attached to the edge of the rafter. On the other hand, the soffit is the one covering the gap between the siding and the roofline. More than just providing a finished look, fascia boards and soffits contribute to weather resistance, keeping the elements from getting into the roof. The fascia boards also keep the gutters in place, while the soffits have strategic perforations for ventilation intake.

Underlayments

These layers of protection blanket the decking to repel wind-driven rain and snowmelt. Acting as a secondary defense against the weather, they’re important accessories to keep decking boards structurally sound.

Asphalt Shingles

They are the actual roof covering. Asphalt shingles have a tough job because they need to remain charming and resilient. In addition to buying high-quality products, observing preventive maintenance is key to shingle longevity.

Eave and Ridge Vents

The combination of eave and ridge vents is synonymous with efficiency. Receiving cold air along low points, and pushing heat and moisture at high points is perhaps the most effective way to regulate roof temperature. This ventilation system is helpful in inhibiting ice damming, among other things.

Flashings

These pieces of metal seal most of the gaps in the roofing system which are the most vulnerable to water infiltration. When made from an algae-fighting material, your flashings can help discourage pronounced shingle discoloration.
