Anatomy Of A Roof: The Importance of Framing & A Roof Deck

Your roof is made up of many different parts, which all need to work together to protect your home from the elements. While each component is required, your roof deck and framing play crucial roles in ensuring the health and longevity of your roof. Learning about these parts, including what they do, can help you better understand how your roof works.

Knowing how to spot problems with your roof deck and framing is also helpful. Keep the following information in mind so you’ll know when they might need to be replaced or repaired.

Purpose of Roof Framing

Roof framing refers to the rafters or trusses designed to support roof decks and shingles. Rafters, or stick framing, are sloped wooden beams forming the frame of a roofing system. Trusses are the framework of sloped wooden beams and horizontal wooden beam pieces.

Rafters and trusses have the same purpose, although they differ in design. Trusses arrive to your home prefabricated while rafters are built on-site.

Importance of Roof Framing

A roof frame serves as a support for your roof, including the roof deck and shingles. Your home needs a durable and sturdy roof frame for structural integrity. Whether your roof frame is made of rafters or trusses, these structures form the base of your roofing system.

Condition of Roof Framing

Moisture or a heavy load can cause damage to roof framing. Water can cause wood rot in rafters or trusses, leading to deterioration. When roof framing has too much weight, additional damage can develop. While rare, a rotting roof frame can cause your roof to collapse, putting your home and family in serious danger.

You can see rafters or trusses in your attic. Checking for signs of damage is essential so you can have them repaired as soon as possible. Signs of damage to roof framing include cracks or buckling in rafter or trusses. You might see water stains or mold growing on roof framing if water damage has occurred.

Purpose of a Roof Deck

Your roof deck is the layer of wood between the framing and shingles. This deck covers your rafters and provides a base for your underlayment and shingles. Roof decks must be sturdy enough to support the rest of the roofing components, so your roof won’t end up sagging or caving in.

Roof decks are typically plywood or Oriented Strand Board (OSB), a plywood composite containing waterproof resin and wood strands. While OSB often costs less, plywood offers more water and moisture damage protection due to its higher density.

Importance of a Roof Deck

The roof deck acts as a support for your roof. If problems develop with the roof deck, such as wood rot, this can affect your roof’s structural integrity. As the roof deck becomes weaker or more damaged, it won’t continue supporting your roof. This can put your roof at serious risk of collapsing.

Condition of Your Roof Deck

Leaks from overflowing gutters, damaged flashing, missing shingles, and other sources can lead to severe water damage and wood rot in your roof deck. It’s essential to watch for signs of roof deck problems, so you can have them repaired promptly. Your roof deck isn’t visible from the outside since your shingles cover it. However, you can check the condition of it from inside your attic.

When you’re in your attic, look around for wet or sagging areas. You should also look for water stains in attic insulation or on the rafters. Other signs to watch for include mold or mildew growth in your attic and light shining through holes or gaps. You should have your roof deck inspected and repaired as needed if you notice any of these signs.

During the Roofing Process

When new roofs are installed, the roof framing is done first. The roof deck is constructed before new underlayment and shingles are installed.
