Full Roof Tear-Off vs. Overlay: What’s the Difference?


Full Roof Tear-Off vs. Overlay: What’s the Difference?

When it’s time to replace your home’s existing roof, you can choose between a full roof tear-off or an overlay. 

A full roof tear-off consists of removing all of your existing roofing materials and building an entirely new roof in its place. An overlay leaves your existing roof untouched. The roofing contractor will simply build a new roof on top of the existing materials. 

There are several factors to consider when choosing between these two options. The following guide can help you choose which alternative is better for your home.

Underlying Materials May Require Roof Repair in Atlanta

One thing to consider is the framing materials beneath your roof. When you overlay a new roof on top of an existing one, the gap between those layers can create an envelope of air that will trap moisture and humidity. As a result, the underlying materials will rot and decay.

Alternatively, a full roof tear-off will enable your residential roofers to see the condition of those underlying materials. If they spot water damage, wood rot, or mold growth, they will recommend replacing those segments. 

Older Homes Can’t Support Excess Weight

As you lay more roofing materials on top of your home without removing damaged roofing, the weight your home will have to support will increase. In an older home, the walls may buckle or break down over time.

When you have Atlanta roofing specialists tear off the old roofing materials, you’ll reduce that weight and alleviate the stress on your home’s structure. After roofing repair in Atlanta, you can trust that it will be long-lasting and effective in protecting your home.

Consider the Time Involved

While roof repair in Atlanta is usually completed within a short timeframe, a full roof installation is much more time-consuming. You can cut down some of this time with an overlay since your roofers won’t spend time removing the existing materials. If you’re in a rush to replace your roof, an overlay may be the better option.

Your Roofing Contractor Can Help with Roofing Repair in Atlanta

Call your roofing contractor if you’re still unsure about which option to choose. They can help you decide which option is better for your home, considering the climate in your region and the age of your house.
