When most homeowners consider roofing parts, they probably think of shingles, gutters and maybe insulation. However, one important roof layer is often overlooked: the sheathing.
Roof sheathing is also known as roof decking. It is a crucial part of the entire roof structure as it helps to prevent an array of different issues and damages.
In addition to that, sheathing a roof can also help you prolong the roof’s lifespan and make your home more energy-efficient.
Read on to learn the proper roof sheathing definition and discover several reasons why roof sheathing is such a crucial component of your roof.
Roof sheathing or decking is an important layer of the roof that sits hidden underneath the top layer of shingles. It is most commonly made out of plywood in the form of planks or roof boards.
These boards can be installed in two different ways and based on the installation method, we can differentiate between two types of roof sheathing. The sheathing can be either open, with gaps between the roof boards, or closed, with no gaps between them.
Ultimately, the type of sheathing you and your roofer opt for will depend on the needs of your roof structure.
A Middletown roofing contractor can ensure that a homeowner’s sheathing is always properly installed and maintained.
Before sheathing became standard on roofs, most roofs simply had a layer of boards underneath the shingles.
Sheathing solves this problem by providing a more continuous, solid layer beneath the shingles that has far fewer gaps or spaces. Proper sheathing is often the key difference between a roof that constantly leaks and a roof that hardly ever does.
The sheathing layer is also a vital part of the support and structure for the rest of the roof. It provides an anchorage for the shingles to be firmly nailed to and, overall, an excellent foundation for all the external roof materials.
All these materials, namely asphalt shingles, metal panels or shingles and similar, are smaller in size and require a broad and sturdy base where they can be safely and firmly attached. Sheathing provides great support for this exact purpose.
Roof sheathing thickness, i.e. the thickness of the plywood boards is also an important consideration here. Their thickness can vary and reach as much as 5 inches. And the thicker the boards are, the heavier and sturdier they will be.
This is important because heavier shingles will need heavier sheathing to support them adequately. Your roofer will ensure that the sheathing is as thick and sturdy as it should be, providing optimal structural support to the shingles.
In addition to anchoring the shingles, the sheathing provides broader roof support by evenly distributing any extra loads the roof may carry.
This includes snow and other accumulation. It also allows more hardware, such as solar panels, to be safely mounted on the roof without causing damage.
Roof sheathing is one of the first elements a contractor is likely to inspect when planning a solar or HVAC installation, for example. This is because the sheathing effectively disperses this extra weight across the rafters and other supporting elements of the roof. It prevents sagging and partial roof collapses.
Roof sheathing thickness is an important aspect here as well. The sheathing planks can be as little as one inch thick and as much as five inches thick. The thinner planks will decrease the overall weight of the roof as well as its cost, and the thicker ones will increase them.
Your local roofer will advise you on the best solution based on the state of your roof, its needs, the weather your area gets, and the amount of support the roof requires.
Generally, thicker sheathing will provide better load tolerance, as well as overall durable and long-lasting protection for the entire roof and your property.
Reflective roof sheathing functions to provide better thermal protection for homes by reflecting the sun and preventing the attic from overheating.
The attic is known to overheat during the summer because the sun’s energy is absorbed by the shingles and therefore transferred to the attic. This, in turn, causes the entire home to heat up more, leading to higher cooling needs and energy consumption.
With reflective roof sheathing, on the other hand, the heat transfer from the shingles to the attic will be significantly decreased, leading to a cooler home, lower energy consumption, and reduced cooling costs.
This can all be achieved simply by installing a radiant barrier on the sheathing. The radiant barrier will help make the home more energy-efficient, which is especially useful in hot climates or on buildings in such climates that may have less insulation.
Sheathing a roof is a crucial process in installing a new roof or replacing your old one because, together with shingles, the sheathing works to fully protect your roof from leaks and water damages.
Roof sheathing is also an important roof element to inspect and maintain on a regular basis.
Properly maintained shingles should adequately protect the sheathing from water and exposure. However, if the shingle layer becomes damaged or if shingles are torn or missing, the vulnerable plywood sheathing may be exposed.
Even if the sheathing does its job to prevent leaks, water may soak into the plywood, leading to rot and failure. Ensuring the sheathing is in good condition is an important part of any professional roof inspection.Have a question regarding roof repairs or skylight installations?
