Your roofing system is not just the part with the shingles and gutters. It’s actually a complex arrangement of components working to keep your home dry and damage-free. One of its less visible parts include the roof deck, which serves as the foundation for the underlayment and roofing shingles. ExteriorPros, one of the most trusted roofing and siding contractors in the area, shares what makes a roof deck a crucial part of a roofing system.
What Exactly Does a Roof Decking Do?
The standard roof structure consists of trusses and joists, but on their own they are just a frame with empty spaces in between. When a roof decking is added to these, however, it provides a flat surface where weather-proofing materials, like the underlayment and shingles, can be attached to. The roof deck is available in different types, including plank, tongue and groove, plywood, and oriented strand board (OSB). Whatever your choice, it will help provide an extra layer of protection between your home and the harsh elements.
Is the Roof Deck Replaced When You Invest in a New Roofing System?
This will depend on its existing condition. Dependable roofing contractors, like ExteriorPros, will inspect your decking to determine if it has dry rot, or if it bends when walked on. Should these be the case, your roofer may replace those compromised sections and leave the good parts intact. However, if the roof deck has sustained extensive damage, it will likely need replacement, along with your old roofing.
Why is the Roof Deck Important?
The roof offers a number of different functions, which may include:
1. Supporting the roofing material. Did you know asphalt shingles are actually heavier than you might expect? To ensure the roof structure can effectively hold up the weight of its layers, the roof deck is there to provide the necessary support.
2. Protecting against impact damage. Flying debris is a common occurrence during storms, and they can damage your roof upon impact. The decking, however, helps distribute weight throughout your home’s structure. This helps it stand up against fallen branches and other debris.
3. Preventing leaks. While the roofing shingles serve as the primary barrier against water infiltration, the roof deck provides an extra layer of protection against possible leakage.
