A roof-over, or the act of overlaying an existing roof, is a job where the roofer places a second layer of shingles directly on top of your roof. It isn’t the most common roofing method, but many homeowners prefer this over a complete roof replacement, where the old shingles are torn off to expose the roof decking or sheathing, and are replaced by a new roofing material.
Most building codes allow for this method, but is it a great investment? Read on as we discuss the pros and cons of a roof-over.
The Advantages of Roofing Over Existing Shingles
One of the most notable benefits of a roof-over is that it costs less than a tear-off. You won’t have to deal with the mess that comes with a complete roof replacement. It helps you save on time as well since tearing off the old shingles is out of the equation. More importantly, you won’t have to pay extra for cleanup, dumpster rental and old roof disposal.
The Disadvantages of Roofing Over Existing Shingles
Unfortunately, it is not the best available option for a variety of reasons. Layering over your old roof prevents the roof repair pros from checking the condition of your decking or sheathing. This important part of your roof could have rotted wood or other signs of damage. Without the benefit of a tear-off, the overlay roof will have a shorter lifespan than the average asphalt roofing system.
Also, multiple layers of shingles make the roof hotter because of the heat trapped between the layers. The new shingles won’t last long because of this, showing signs of blistering, curling or cupping much like the old shingles underneath.
As you can see, roofing over presents more cons than pros. It does help you save on costs, but it won’t be worth it in the long run. If you want your new roof to last longer, it would be better off for your roof replacement to involve a complete tear-off.
