Are you thinking about a new roof? Let us help explain some of the common terms associated with your roof.
The main roof components:
Roof Deck: The base layer of the roof that supports the whole roof system
Drip Edge: This is most often metal and lays on the Roof Deck. The Drip Edge extends beyond your base layer and allows water to drip into gutters and off of the roof. It also prevents wind from getting underneath the shingles.
Ice and Water Shield: The Shield is self-adhesive and attaches directly to the drip edge and decking. While water could potentially get through your shingles, the Shield prevents it from getting to your roof deck. Water on your roof deck could cause mold and rot!
Underlayment: The Underlayment is an extra layer of protection against severe weather. Allstate Roofing & More, LLC manufactures and uses Dry-Deck, a breathable, water resistant underlay—which comes with a 50-year limited warranty!
Shingles: There are typically two layers of shingles—the starter layer which has a tar strip on the top of the shingle, and the top layer which has a tar strip on the bottom of the shingle. The tar strips adhere to each other for a double seal, which helps prevent wind from getting under and impacting the shingles.
Venting: Without proper venting, your whole roof system will collapse. Roofs each have a soffit vent which is an “intake” vent at the bottom of the roof, and a ridge vent at the top of the roof. This system allows hot air to go out the ridge vent, and cool air to come in through the soffit vent. Without good venting, in the summer shingles can scorch and glue can actually melt on the roof! In the winter, it could impact the heating bill at your home, and in the rainy season, lack of good ventilation can cause mold.
Eave: The edges of the roof that hang over the wall. Fascia and Soffit make up the eave
Fascia: A level flat wood or board that the gutters hang on. It is directly below the roof itself.
Soffit: The underside of your roof’s overhang.
Soffit Vents: Vents in the soffit that allow for fresh air to ventilate through the roof system.
Ridge: Basically the peak(s) of the roof.
Ridge Vents: Vents put into the ridge, and often covered with shingles that allows for hot air to vent out of the roof system.
Pitch: Essentially how steep your roof is.
Truss: The “skeleton” framework that supports the structure of the roof.
Tear-Off: Removing the components of an existing roof, all the way down to the roof deck.
Cedar Tear-Off: In many older homes, cedar shingles actually act as the roof deck. They are not water tight, as they have nail holes in them. Often, typical asphalt shingles are laid over the cedar (sometimes several layers of them), and the cedar can’t be seen. It is often very hard to tell if cedar shingles are a part of your roof without looking in the attic or crawl space at the underside of your roof. If cedar shingles are present, often they will be torn off, and a new roof deck installed.
