Knowing when to Replace a Cedar Roof

How do I know if it’s time to replace my roof?


Many times, even a roof which has lost its visual appeal is still functional. Instead, most cedar roofs are replaced because they have lost their aesthetic value and not because of their functionality. Cupping and curling are two major issues in older, primarily unprotected or poorly install cedar roofs.

Cupping and curling are caused by numerous factors, including UV damage and moisture, and are typically more prevalent on the southern facing roof facets. Direct sunlight is the biggest enemy of all roofing materials. This damage is also caused by poor quality cedar, poor quality installation and a lack of ventilation in your roof structure. Once the cedar has curled there is nothing that can be done to reverse it.

At this point, we may recommend the roof be cleaned and preserved. This will block out the harmful UV rays and repel moisture. Once protected, the cedar will not expand and contract as much, limiting the amount of ongoing degradation. This damage though can eventually lead to tangible concerns. Many leaks can be repaired with minimal time and materials, allowing you time to consider your options which may include preservation, renailing and full or partial replacement.
