Roof Overlay vs Tear Off Installation and Repair

If you’ve got to replace your roof, should you go with a roof overlay or for a complete tear-off solution? Asphalt shingles are by far the most popular roofing material, with around 80% of homeowners choosing the material. A good roof does a lot to protect a home from the elements and enhance curb appeal. It can be one of the largest purchases that you have to make with regard to home maintenance and upkeep.

Overlay Roof vs. Tear Off

Overlay – Adding a second layer of shingles. The majority of building codes allow for two layers of asphalt shingles so you might not have to strip everything down to the plywood sheathing depending on your area. Adding a second layer of shingles is faster and less expensive, but it doesn’t allow you to inspect the sheathing for signs of damage. If your roof is in overall good condition and underlying damage isn’t suspected, an overlay installation may be a good option for you for your roofing repair needs.

Tear Off – Stripping away everything. This is the more expensive and time-intensive route. If you have the budget available then this is usually the preferred option because it allows for a full inspection of the sheathing, and allows for the installation of new flashing and the shingles can lie flatter.

Cost Breakdown

• Materials 55% – In a tear off there is more material to purchase with under-layments and starter strips. With an overlay the shingles make up the bulk of the material and it ends up being around 65% of your total cost.
• Labor 35% – Roofing is a labor intensive and complicated job, especially when doing a full tear off. An overlay reduces labor costs to around 25%.
• Waste Disposal 5% – The cost for renting a dumpster and hauling all of the old materials away.
• Various 5% – This can be anything from the cost of renting a crane to lift materials up to a high roof to scaffolding or other things.

Don’t Put-off Roofing Repairs

If your roof is in need of repair, don’t wait unnecessarily for getting things taken care of in a timely manner. Repairs will only get more expensive and more damage likely to the rest of your home if delayed too long. Whether it’s to continue protecting your family and possessions from the weather and keeping them safe, or just to improve your overall curb appeal for your own enjoyment or when you’re ready to sell.
