Your roof is a system of interconnected parts that perform vital functions. One of the most important components of a roofing system is the decking, which provides the unseen support structures underneath the underlayment and shingles.
As a homeowner, it’s important to have a basic understanding of what your roof deck is and how it works. This can allow you to better care for your roofing system as a whole. Read on as A1 Siding & Roofing shares a quick overview of this important part of your roof.
Types of Roof Decks
Roof decks make up for the basic framework of a residential roofing system. This includes the trusses, joists and even the sheathing where shingles are installed. There are several styles of roof decks with different arrangements of these parts:
- 1. Tongue and groove decks have planks with a “tongue” edge and a “groove” edge. The tongues slide into grooves making for an almost seamless, nail-free construction.
- 2. Plywood sheathing features expansive sheets of plywood to cover the framework. These plywood products must be matured and moisture-resistant. Avoid wood with knots on the surface as this can lead to an uneven deck.
Replacing Roof Decks
A roof replacement does not necessarily need to involve a deck replacement. Once the shingles have been torn off during the replacement, the contractor can inspect the deck and determine whether replacement is warranted. Deck replacements can be expensive, almost like building a new roof from scratch. Talk to your contractor to ensure that a roof deck construction is needed.
