Get to Know Your Roof! A Guide to Identifying Roofing Parts and Problems

Many homeowners don’t know much about the different parts of their roof. While you don’t need the same level of expertise as a professional Edmonton roofer, knowing a bit about your roof’s different components can help you figure out when it’s time for roof repair or replacement. The Edmonton and Sherwood Park roofing contractors at A. Clark Roofing & Siding LP. have put together a basic guide to different roofing parts and how to spot problems in them.


The first layer of a roof, decking rests on top of the rafters and serves as a rigid base of support for the subsequent layers. It is typically made of plywood or particleboard. One of the tell-tale signs of trouble with decking is a roof leak. Old and damaged decking will also often visibly sag.


Installed directly on top of the decking, underlayment is usually made of a heavy felt or a felt-like material that is used for additional moisture protection. As it is intended to keep moisture out, roof leaks are a definite sign that your underlayment needs repair.

 Exterior Layer

The exterior layer of a roof is the part that most homeowners are familiar with. Asphalt shingles are most popularly used for this layer, but roofing materials such as cedar, concrete, or metal are a good option as well. If the top layer of a roof requires repair, then it will typically show visible signs of damage. Shingles, for example, may become cracked or curled, or missing altogether.


Vents are necessary to ensure that the attic is properly ventilated. They protrude from the roof surface and are typically made of metal or plastic. Roof vents should always appear to be in good condition, without any obvious signs of damage.


Flashing is a layer of sheet metal that is installed around valleys and roof protrusions such as vents and chimneys to prevent water leaks. In order to do its job properly, flashing must be free of damage and rust.


“Fascia” is the name given to the trim boards running along the edge of a roof and covering the eaves. Gutters are typically attached to the fascia. Fascia boards need to be replaced if they appear split or decayed. Note that decay on the fascia often signifies more serious roofing problems.

Gutters and Downspouts

Gutters and downspouts serve to direct water off the roof and away from your home’s foundation. If they are damaged, rusted, sagging, or clogged with debris, it can cause water to pool and stream down the sides of your home.
