Frequently Asked Questions
In this section, we address some of the most common questions related to putting plywood over shingles.
Can I install plywood over existing shingles?
While it’s technically possible to put plywood over shingles, it’s generally not recommended. Plywood is not designed to be used as a roofing material on its own. When installed over shingles, it can trap heat and moisture, leading to potential issues like rot and mold. Additionally, adding another layer of plywood can increase the load on your roof, potentially compromising its structural integrity. It’s best to consult with a professional roofer before making any decisions.
What are the risks of putting plywood over shingles?
Putting plywood over shingles can lead to several risks. As mentioned earlier, it can trap heat and moisture, creating a breeding ground for rot and mold. This can cause damage to both the plywood and the underlying shingles. Additionally, the additional weight of the plywood can strain the roof structure, especially if it was not designed to handle the extra load. Over time, this can lead to sagging or even collapse. It’s crucial to consider these risks and consult with an expert before attempting to install plywood over shingles.
Is it possible to install plywood over shingles for temporary repairs?
In some cases, installing plywood over shingles for temporary repairs may be acceptable. For example, if your roof has experienced damage and you need to protect your home from further water infiltration, plywood can act as a temporary barrier.
