The essential parts of a
Shingled roofing system

Your roof has many parts, each playing a vital role in the protection of your home. Most people know about shingles however there are other layers that are essential for your home to be well protected. See following graphic.

Leak Barrier

Leak barriers, or ice and water shields, are self-sealing underlayment's. This means that in addition to offering easy, roll-on installation, the protective underlayment seals down tight around nails to keep intrusive water at bay.

Leak Barrier Product


Underlayment is what lies between the shingles and the roof sheathing, or roof deck, which is typically either plywood or OSB. It's installed directly on the roof deck and provides a secondary layer of protection from the elements, including rain, snow, and wind.

Starter Strip

A shingle starter strip is an important part of a residential roofing system. It plays a critical role in reducing the risk of shingle blow-off along the eaves and rakes of the roof. It provides a base under the shingle at the eaves, helping the roof shed water efficiently. As its name implies, every asphalt shingle roof will start with this shingle.

Starter Shingle Product


Roof shingles are a roof covering consisting of individual overlapping elements. These elements are typically flat, rectangular shapes laid in courses from the bottom edge of the roof up, with each successive course overlapping the joints below. Shingles are held by the roof rafters and are made of various materials such as wood, slate, flagstone, metal, plastic, and composite materials such as fibre cement and asphalt shingles.

Shingle Product


Roof ventilation allows air to flow through the attic space, escaping through the roof vents. Properly installed roof vents will prevent the roof from overheating. They also prevent condensation from developing. When the roof overheats or moisture builds up, this can lead to substantial damage or health risks.

Ventialtion Product


Ridge cap shingles are like regular shingles in that they use the same material and offer the same look in terms of color; but they are different in that they are specially designed to cover the ridges of the roof, which are high-stress areas that need more protection, unlike with metal roofing.
