If you’re wondering whether roof repair patch will void a CertainTeed manufacturer warranty, the answer depends on how the repair is handled and who does it.
When are roof repairs safe and under warranty?
- Manufacturer-approved repairs: If you hire a CertainTeed-certified contractor (such as a ShingleMaster or Select ShingleMaster), they can perform roof repair patchwork that won’t void the warranty, as long as the work follows CertainTeed’s specified installation procedures and gets prior written approval if needed
- Documentation and prior approval: Any repair, alteration, or addition to your roof that impacts the product or adjacent materials typically requires prior written consent from CertainTeed. If you don’t get that approval, the material warranty may be voided
When Repairs May Void the Warranty
- Unauthorized or DIY patches: Any patch, repair, or alteration done without prior written approval from CertainTeed can void the warranty
- Non-certified contractor work: Repairs performed by someone not certified by CertainTeed may be considered unauthorized, and thus may invalidate warranty coverage.
- Improper installation practices: If the repair includes incorrect fastening, inadequate ventilation, or deviates from CertainTeed’s installation guidelines, the manufacturer warranty could be voided
What to Do Before Getting a Roof Patch
- Contact CertainTeed Technical Services: Before any repair is made, reach out for written approval for the specific patch or alteration.
- Use a certified contractor: Choose a licensed contractor, like J. Bos Inc. Roofing Services, with CertainTeed certification to ensure proper installation and warranty standing.
- Keep good records: Document all approvals, invoices, and correspondence related to the repair work.

Roof patches doesn’t inherently void the warranty.
Roof patching does not inherently void a CertainTeed manufacturer warranty, if it’s done properly: by a certified contractor, in line with product specs, and with prior written approval from CertainTeed. However, unauthorized or improperly executed repairs can invalidate warranty coverage, even for just the affected area.
