In Coeur d’Alene, a roof overlay involves adding a new layer of shingles over an existing one. This cost-effective alternative to a full roof replacement can extend the life of your roof under certain conditions. At SkyRight, we help homeowners navigate their options to make the best roofing decisions for their homes.
How Roof Overlays Work
A roof overlay adds a new shingle layer directly on top of the old one. It avoids the time and expense of removing the existing roof, offering a quicker solution for improving roof durability.
Key Conditions for a Successful Roof Overlay
1. Strong Roof Decking
The roof deck must be structurally sound to support the additional weight of a second layer of shingles. Weak decking can lead to roof failure.
2. Good Condition of Existing Shingles
Existing shingles should be intact. Cracked or missing shingles indicate underlying issues, making an overlay unsuitable.
3. Limit of Two Layers
Most roofs can only accommodate two shingle layers. Exceeding this can compromise the roof’s structural integrity, necessitating a complete replacement.
Unique Fact: Weight of Shingles
Asphalt shingles typically weigh between 200–400 pounds per square (100 square feet). Adding a second layer significantly increases the load on your roof.
Advantages and Limitations of Roof Overlays
Advantages:
- Cost Savings: Cheaper than a full replacement due to reduced labor.
- Quick Installation: Faster process without tear-off requirements.
- Enhanced Curb Appeal: Improves the roof’s appearance.
Limitations:
- Hidden Issues: Underlying problems may remain unaddressed.
- Shorter Lifespan: Overlays don’t last as long as new roof installations.
- Weight Concerns: Additional weight can strain the roof deck.
When to Consider a Full Replacement
If your roof already has two layers or shows signs of extensive damage, a tear-off and full replacement are better options for long-term safety and performance.
