Parts of a Roof You Want to Know About
When it’s time for a Roof Replacement and you’ve found a qualified and reputable contractor to do the job, it’s a good idea to also be familiar with terms included in your estimate. We’ll share parts of a roof that you should know about.
- Flashing: Materials used to waterproof a roof around any projections, and there are several on the roof. This term, more than any other mentioned below, will show up in most estimates. Read over carefully and understand the difference between replacing the flashing or re-using the old flashing, especially in regards to your warranty.
- Chimney: Yes, the part that noticeably sticks out above the roof. Did you know that not all chimneys are square? Some are round and even square on the bottom and round on top. No matter the shape they still serve the same purpose, which is to provide ventilation from an inside source to the outside atmosphere. Flashing will be found around the bottom of the chimney where the roofline meets and this may be one of the areas described in your estimate whether to reuse or replace during a roof replacement.
- Skylight: The window in the roof facing the sky that radiates natural light into the home. Ahhh. Skylights have come a long way adding layers of protection, better flashing design, improved energy efficiency and ventilation with a touch of a button. Flashing around the skylight is what keeps it air and water tight. Pay attention to the estimate where your skylight is mentioned.
- Dormer: A window extended from the roof with shingles on it is called a dormer window. The dormer is the roof layer above it. Other than adding a fascinating dimension to any roof, it offers several cool benefits, such as more daylight, ventilation and head space.
- Ridge: The highest point on a roof where two sloped roof areas meet and are utilized for enhancing attic and roof system ventilation. There are different options for ridge caps. Some are more aesthetically pleasing. Be sure to choose one that works best with your roofing system and that will do its job, which is to add protection.
- Valley: The Vee shaped metal channels that run up and down the ‘folds’ of a roof. They are the opposite to a hip as they are the internal version. Leaves and debris are notorious for building up in the valley and problems can easily develop if they aren’t cleaned off regularly.
- Plumbing Vent or Vent Pipe: Ever noticed the skinny pipes sticking up from the roof? They supply air to the drain pipes for liquid to flow properly and are designed to help prevent sewer gas from coming into the home.
- Hip: A roof with four roof planes coming together at a peak and four separate hip legs. A hipped roof house has no gables or other vertical sides to the roof. You can read more about these types in What Design is Your Roof.
- Eave: The roof edge from the fascia to the structure’s outside wall. They form an overhang to throw water clear of the walls and prevent wood rot.
- Facia: The exposed band under a roof edge that is visible to an observer. May not seem like much to look at, however it plays an important role by keeping pests like squirrels, birds and bats from entering into your home.
- Rake Edge: The vertical edge of gable style roof planes that prevents rain from running behind it.
- Side Wall: Where a vertical roof plane meets a vertical wall, such as the sides of dormers, etc.
In unity, the functions of all parts of a roof are to keep the inside of your home dry, protected and free of uninvited visitors.
