Roof Repairs – Damaged Sheathing And What To Do With It

roof repairs - sheathing repairs

In our previous article, we established the basics of the individual elements that make up your roof and how they work in tandem to provide you with the safety and comfort you expect from your home. Once you understand the basic functionality of your roof, it’s far easier to understand when your roof will need repairs.

Your roof’s sheathing is the foundational protective layer. Properly installed sheathing can last a lifetime, which is why many homeowners are confused when faced with the prospect of replacing it. Patching the occasional leak in the home is one thing, but excessive exposure to moisture can damage your Sheathing and your home.

Not all homes use the same type of sheathing. Typically, modern roofs are constructed using 4 x 8 sheets of plywood or oriented stratboard (OSB). The main distinction between plywood and OSB is one of cost, as OSB is usually available at a cheaper price. However, there is evidence showing that plywood is considerably more resistant to condensation, while OSB is likely to swell and become deformed more easily with exposure to moisture.

The replacement process begins by removing the shingles on the surface to access the sheathing beneath. After the shingles have been removed, the damaged layer is ready to be inspected for replacement. The replacement patch must be the same thickness as the damaged boards. Once cut to size, the replacement board can be nailed to the existing board.

While the process for replacing damaged sheathing may seem simple, there are many considerations to keep in mind. When sheathing must be repaired, it’s also of vital importance to identify and repair the source of moisture to ensure no future sheathing issues. Similarly, one must trust a professional when cutting damaged sheathing, as the boards can contain electrical wiring.
