Never overlay your new roof
Why You Should Never Overlay a New Roof on an Old Shingle or Metal Roof | Alpha Kings Construction

When it comes time to replace your roof, some homeowners consider overlaying new shingles or metal panels on top of an existing roof. While it may seem cost-effective, this approach often creates more problems than it solves. At Alpha Kings Construction, we advise homeowners in Massillon, Canton, Akron, Medina, and surrounding Northeast Ohio to always remove old roofing before installing a new system. Here’s why.
1. Hidden Damage Can Go Undetected
Old roofing can hide serious problems such as:
- Rotting or damaged roof decking
- Water damage or leaks
- Mold and mildew growth
Overlaying new material simply covers these issues instead of addressing them, potentially leading to more expensive repairs down the road.
2. Reduced Lifespan of the New Roof
Installing new shingles or metal panels over old material can significantly reduce the lifespan of your new roof. Underlying problems can cause:
- Uneven surfaces that stress shingles or panels
- Trapped moisture leading to faster deterioration
- Premature curling, cracking, or metal warping
A proper tear-off ensures your new roof starts with a solid, even foundation for maximum durability.
3. Warranty Issues
Most roofing manufacturers will not honor warranties on roofs installed over existing materials. If damage occurs, your investment may not be protected. By removing the old roof, you qualify for full manufacturer warranties and gain peace of mind.
4. Code Compliance and Building Safety
Local building codes often limit the number of layers allowed on a roof. Installing multiple layers can:
- Add excessive weight to your roof structure
- Increase fire risk in some cases
- Fail inspections when selling or refinancing your home
A tear-off ensures compliance with all local regulations and safety standards.
5. Improved Energy Efficiency
Old roofing can trap heat, reduce insulation effectiveness, and create ventilation issues. By removing old layers, you can:
- Install proper underlayment and ventilation systems
- Improve attic airflow
- Reduce energy costs and prevent ice dam formation in winter
6. Better Long-Term Value
While an overlay may save money upfront, it often costs more in the long run due to hidden damage, repairs, or shorter roof lifespan. A complete tear-off ensures:
- Maximum roof longevity
- Fewer maintenance issues
- Full insurance and manufacturer coverage
- A clean, professional installation that enhances home value
