When considering roof repairs or replacements, homeowners may encounter the option of a roof overlay. Champion Restoration and Construction provides a detailed explanation of what a roof overlay involves, its drawbacks, and why a complete tear-off is often the better choice.
What is a Roof Overlay?
Definition
A roof overlay involves placing a new layer of shingles over the existing shingles without removing the old roofing materials. This process may seem like a quick fix, but it has several significant drawbacks.
Drawbacks of a Roof Overlay
Temporary Solution
An overlay is merely a temporary fix that covers up existing problems rather than addressing them. This can lead to more significant issues down the line, as the underlying problems remain unresolved.
Increased Weight
Adding an extra layer of shingles can add up to 5,000 pounds of weight to your roof. This additional weight can introduce structural problems that did not exist before, potentially compromising the integrity of your home.
Potential for Hidden Damage
Overlaying shingles does not allow for an inspection of the roof deck. Problems such as mold, mildew, and rot can continue to grow unnoticed under the new layer of shingles, leading to more extensive damage.
Reduced Longevity
Overlays do not last as long as complete roof replacements. When it comes time to replace the roof again, you will need to remove two layers of shingles, increasing the cost and complexity of the project.
Warranty Issues
New shingles placed over uneven or damaged old shingles may not lie flat, leading to potential wind damage and voiding any warranties on the new shingles.
The Complete Roof Tear-Off
Definition
A complete roof tear-off involves removing all existing layers of shingles and inspecting the roof deck for any damage before installing a new roof. This process ensures that all issues are addressed and that the new roof is installed on a solid foundation.
Benefits
Thorough Inspection
A complete tear-off allows for a thorough inspection of the roof deck. Any mold, mildew, rot, or other damage can be identified and repaired before the new roof is installed.
Improved Ventilation
Removing the old roof allows for the installation of improved ventilation systems. Proper ventilation is crucial for maintaining the longevity of your roof and preventing future issues such as ice dams and condensation.
Modern Roofing Technology
Roofing technology has likely advanced since your last roof installation. A complete tear-off allows you to take advantage of the latest materials and techniques, providing better durability and energy efficiency.
Warranty and Value
A new roof often comes with a warranty, which can be a significant selling point if you plan to sell your home in the future. A complete tear-off and replacement also have a higher return on investment compared to an overlay.
