Both metal and concrete roof types are subject to corrosion. Box gutters are particularly susceptible as water pools for long periods of time. The result is pin holes develop and joint seals break down causing leaks. The leaks are often hard to locate and repair.
Roof penetrations are also a weak point and are the most common source of leaks.
CCA provides a service to locate and seal the leaking areas using fast cure membranes, combined with sealants which can be applied to wet surfaces. Corrosion treatments are also applied to the rust affected areas. Larger holes are patched using a flexible flashing taping system.
