When it comes to roofing, is it better to do an overlay or a roof tear-off?

Roof Tear-Off vs. Roof Overlay: What's The Difference?

During a roof tear-off, professionals will remove your existing roof, providing a clean slate to install the new roof. The roofers will carefully remove every shingle from your roof using a tear-off fork, check the decking for any structural damage or other issues, and proceed to your roof installation.

On the other hand, a roof overlay involves the installation of new shingles directly over the existing ones without removing the old roof. However, regulations typically allow only two shingle layers on a roof. Therefore, if your roof has undergone a previous overlay, opting for a total roof replacement is advisable.

Roof Tear-Off: Pros and Cons

Pros:

1. Proper Inspection: Roof tear-off allows a thorough examination of the roof deck. This enables roofers to repair any damage and ensure a strong and durable base for your new roof.

2. Brand-New Materials: With a tear-off, you get all-new materials, from decking to shingles, resulting in a long-lasting and durable roofing structure.

3. Increased Home Value: Completely replacing your roof through tear-off can boost your home's value and offer future owners confidence in the structural integrity of the roof.

Cons:

1. High Cost: Most roof tear-offs are more expensive than overlays due to the extended process and increased material requirements.

2. Longer Replacement Time: Tear-offs take more time than overlays.

Roof Overlays: Pros and Cons

In some cases, a roof overlay offers certain advantages over tear-offs:

• Cost-effectiveness: Roof overlays are more budget-friendly. This process requires less material and labor as compared to tear-offs.

• Quicker completion: An experienced roofing contractor can finish overlays much faster than tear-offs.

However, roof overlays are generally inferior to tear-offs in several aspects. This process can:

• Trap moisture, leading to water damage and mold growth between shingles.

• Put the excess burden on your home due to the weight of additional shingle layers.

• Have a shorter lifespan than a roof tear-off.

• Often deliver uneven results

How to Choose the Right Roof Replacement Method?

In most cases, a roof tear-off is the wiser choice over a roof overlay. Although overlays may seem more affordable upfront, they can lead to future issues and require more repairs and maintenance.

Yet, there are some cases where a roof overlay can be considered. A roof overlay could suit your needs if your roof is in good shape but wants to change its material or appearance. Additionally, an overlay could serve as a cost-effective solution if there are any budget constraints or time limitations for a complete replacement.

We strongly recommend this approach if you can afford a total roof replacement. A tear-off ensures a longer-lasting and more robust roof. This process also eliminates all types of hidden damage.
