Can You Recover Architectural Shingles?

The quick answer is yes, you can re-roof architectural shingles over existing architectural shingles. However, it’s crucial to check with the shingle manufacturer for their specific recommendations, as some designs may not be suitable for this approach.

Considerations for Recovering Architectural Shingles
Potential Challenges
While recovering architectural shingles is possible, it’s important to be aware of the potential challenges:

Uneven Surface: Existing shingles may create an uneven surface, making it difficult to achieve a flat, smooth finish with the new shingles. This can result in an unsightly, lumpy appearance.
Weight Concerns: The additional layer of shingles adds weight to the roof structure, which may not be designed to support the extra load. This could lead to structural issues over time.
Ventilation and Insulation: The existing roof system’s ventilation and insulation may be compromised by the additional layer, potentially affecting the roof’s performance and energy efficiency.

Manufacturer Recommendations
Before proceeding with a recover, it’s essential to consult the shingle manufacturer’s guidelines. Some manufacturers may not recommend installing new architectural shingles over existing ones, as it can affect the product’s warranty and performance.

Factors to Consider

When deciding whether to recover or replace your architectural shingles, consider the following factors:

Condition of the Existing Roof: If the existing shingles are in good condition, with minimal wear and tear, a recover may be a viable option. However, if the shingles are significantly damaged or deteriorated, a full roof replacement may be the better choice.
Local Building Codes: Check with your local building authorities to ensure that a recover is permitted in your area. Some jurisdictions may have restrictions on the number of roof layers allowed.
Cost Savings: Recovering can be a more cost-effective option compared to a full roof replacement, as it eliminates the need for tear-off and disposal of the existing shingles.

Ultimately, the decision to recover or replace your architectural shingles should be made in consultation with a reputable roofing contractor, who can assess the specific conditions of your roof and provide a recommendation based on your needs and budget.
