Maintaining a flat roof in Washington involves keeping drains and scuppers clear to prevent water pooling and ensuring regular inspections after winter freeze-thaw cycles. We recommend bi-annual professional inspections to check membrane seams, remove debris accumulation, and address any ponding water issues before they lead to leaks or structural damage.

A flat roof likely needs replacement if it is over 15 years old, exhibits widespread membrane cracking or bubbling, or shows persistent ponding water and multiple leak points. Isolated leaks or minor membrane punctures can often be addressed with a professional repair, which we determine during our free on-site inspection.
