If you’re thinking about upgrading your roof, you might be wondering: can I install a metal roof over my existing shingles? At Classic Products Roofing Systems Inc, we specialize in metal roofing solutions for Ontario homeowners and can help you understand your options.
Installing Metal Roofs Over Asphalt Shingles
For many homes, architectural steel or aluminum shingles can be installed directly over one layer of asphalt shingles. This approach is convenient, cost-effective, and fully compliant with Ontario building code weight requirements. However, if your roof has two or more layers of shingles, we recommend removing them before installing a metal roof.
Stripping the old shingles is required for standing seam metal roofs.
Ice and Water Protection
When installing on a bare plywood deck, our team usually applies ice and water protection across the entire roof. This premium practice adds an extra layer of protection against leaks and ice dams.
Interestingly, if you’re installing over existing shingles, ice and water is typically not required, since the old shingles already provide some water protection.
Benefits of Installing Over Existing Shingles
- Less labor and waste: No need to tear off the old roof.
- Faster installation: Your new roof goes on more quickly.
- Cost savings: Reduces disposal fees and installation costs.
