Installing a Roof Atop Old Shingles
While some roofing contractors suggest installing your new roofing over your old shingles, this is usually a bad ideal. The price tag for an overlay installation is generally cheaper, but it decreases the life span of your shingles (and can even void the warranty on some roofing products). Although the initial outlay is less, when heat and moisture trapped by the lower layer of shingles cause your new roof to deteriorate, you’ll have to spend more money to have another new roof installed. Most high-quality roofers won’t recommend taking this short cut, so if your roofing company advises an overlay installation, it may be time to start shopping for different roofing contractors!
Installing New Shingles on Damaged Decking
Putting a new roof down on damaged decking is a recipe for disaster. Rotting and decaying plywood not only creates an unsafe working service for the roof installers, it will also result in an unsound roof. Moisture issues as well as structural collapse are possible-and, quite frankly, likely-when you don’t have damaged decking replaced. It adds some cost to the roofing installation, but your roof will be sound and last years longer when it is installed on solid decking. If you’re not sure whether your decking is in satisfactory shape, ask your roofer. They’ll be able to assess the particulars of your roof and recommend whether decking replacement is needed.
Repairing a Roof With Shingles Past Their Expected Life Span
You’ll also want to keep in mind that roofs have recommended life spans. Once a roof is past that age, you’re almost always better off replacing the whole roof rather than repairing it. Even if you only have a major problem with one small section, other parts of the roof are likely to deteriorate soon. You will save money, hassle, and aggravation by replacing your whole roof once it has surpassed its suggested lifetime.
With these three issues in mind, you’ll be able to make informed decisions about replacing or repairing your roof. As you can see, cheaper is rarely better with roof replacement-cutting cost means cutting corners. Although it may cost a little more initially, you will save money in the end doing your roof right the first time! Be sure to always using a licensed roofing contractor for the best quality installation and a superior roof.
