The roof deck (wood) forms the crucial layer between the structural components (such as joists and rafters) and the insulation and waterproofing layers (like ice and water shields, synthetic felt, and shingles). It's the foundation upon which the entire roofing system is built. If the roof deck is compromised, the integrity of the entire roofing system is at risk!

Ice and water shield is a self-adhering waterproof underlayment used in roofing to protect against damage from ice dams and wind-driven rain.

Synthetic underlayment is a layer of laminated polypropylene or polyethylene plastic that is applied over the roof deck. Its primary purpose is to offer an additional layer of protection for the roofing system. This durable material is moisture-resistant and can be exposed to the elements for extended periods without compromising its effectiveness.

Drip edge is metal flashing installed along the roof's edges to direct water away from the fascia and prevent it from seeping beneath roofing components and damaging the roof deck. Without drip edge, water can infiltrate behind the gutters, leading to rot in both the fascia board and roof decking.

A starter strip is an asphalt-based shingle used to waterproof the eaves and rake edges of your home during re-roofing. Its adhesive tar strips provide extra protection by helping to prevent shingle blow-off in harsh winds.

Asphalt shingles consist of several layers: a base mat, a layer of waterproofing asphalt, and a layer of ceramic granules. One of these layers is fiberglass, which enhances durability and strength.

Ventilation is crucial for optimal roof performance. Installing roof vents helps regulate the temperature in the attic or roof space, preventing extreme heat or cold. This reduces moisture buildup, which can lead to mold growth and ensures that roofing components function effectively.
