5 Reasons a Complete Roofing Tear-Off Beats an Overlay Roof

You have two options – a complete roofing tear-off or an overlay – if your northern Utah home needs a new roof.

With an overlay roof, the new shingles are placed on top of the existing roof. A tear-off, on the other hand, involves removing all of the old roofing material first. As you might expect, going the overlay roof route is less expensive and takes less time. However, for several reasons, opting for a complete roofing tear-off is a better long-long term plan.

oofing, Tear-Offs

No. 1: Roof Deck Damage

How long ago was your existing roof system installed? If you’re like most Utah homeowners, it’s been decades – and after all that time, the deck may have dry rot, mold or water damage. Doing a complete tear-off is the only way to reveal if the deck needs repair. Choose an overlay instead, and unseen damage won’t be evident until your home springs a roof leak.

No. 2: Weight Load

With an overlay, you’re adding quite a bit of weight at the top of your home – roofing shingles are heavy! If your northern Utah home is older, it may not be able to handle the additional load. Go with a complete roofing tear-off, and you won’t have to worry about the structural integrity of your new roof.

No. 3: Durability

Since a complete tear-off replaces the entire roof system, this option offers the longest-lasting results. Professional roofers can install new flashings and add support in high-risk areas, ensuring that your home remains leak-free and secure for many years to come. Roofing overlays aren’t nearly as durable.

No. 4: Home Value

A brand new complete tear-off roof boosts your northern Utah home’s resale value. For most home buyers, this type of roofing is a major selling point. In contrast, an overlay can be a disadvantage, as it means the roof system has a greater chance of springing a leak or needing repairs soon.

No. 5: Warranty

In some parts of northern Utah, the building codes limit roofing to two layers, so an overlay may not be an option if you’ve already had one done. Furthermore, roof system warranties may only cover a complete tear-off, as the manufacturers don’t want to be held liable for issues that occur as a result of installing new shingles on a potentially damaged deck.
