Understanding the Use of Existing Flashing in Roofing Projects
In roofing projects, particularly those involving Owens Corning® Extended Warranties, the condition and quality of flashing are critical. Flashing is a key component in protecting vulnerable areas of the roof, such as chimneys, valleys, and wall intersections. This technical bulletin outlines the guidelines for re-using existing flashing under Owens Corning’s Extended Warranties.
Importance of New Flashing
A roof is only as durable as its weakest component. Owens Corning recommends using new flashing to ensure the integrity and longevity of the roof system. The new flashing must meet all local building codes and installation requirements, including step flashing, continuous flashing, side wall, front wall, chimney flashing, valley metal, and any specialty flashing.
Can Existing Flashing Be Re-Used?
While Owens Corning typically requires new flashing for roofs covered under their extended warranties, there are exceptions. Different architectural designs and exterior cladding styles, such as vinyl, aluminum, wood, stucco, brick, and cementitious board, can make replacing existing flashing without damaging the cladding challenging. In such cases, re-using existing flashing is permissible under specific conditions.
Conditions for Re-Using Existing Flashing
- Condition:
- The existing flashing must be in like-new condition.
- It should not show signs of buckling, rusting, bending, cracking, or breaking.
- Compliance:
- The flashing must be of the proper gauge required by local building codes.
- It must be installed according to the manufacturer’s and building code requirements.
When to Avoid Re-Using Flashing
- Damage Indicators:
- Do not re-use flashing that is buckled, rusted, bent, cracked, or broken. Using compromised flashing can lead to leaks and reduce the roof’s overall effectiveness.
Recommendations for Roofing Contractors
- Inspection:
- Carefully inspect existing flashing to ensure it meets the conditions for re-use. If there is any doubt about its condition, replace the flashing to maintain the warranty and roof integrity.
- Compliance:
- Ensure that all new or re-used flashing complies with local building codes and is installed correctly.
- Consultation:
- If there are any questions or uncertainties about re-using existing flashing, contact Owens Corning Roofing and Asphalt for guidance.
Conclusion
Using proper flashing is essential for the durability and performance of a roofing system, especially under Owens Corning Extended Warranties. While new flashing is generally recommended, existing flashing can be re-used under certain conditions. Ensuring that flashing is in excellent condition and properly installed is key to maintaining roof integrity and warranty compliance.
