When do you replace a roof rather than patch and/or repair it?
Maintenance and repair of wall flashings can help extend the serviceable life of the roof system. Once the field (flat section) of the roof starts splitting it is time to replace the roof. Field repairs will occasionally hold, but when they become a regular problem, failure will occur in the not too distant future.
Periodic roof Inspections are a MUST.
If the roof doesn’t leak, don’t fix it. WRONG!
Unseen problems may be looming and will be revealed by periodic roof inspections, subsequently extending the life of a roof by many years. Even newer roofs should be inspected once a year to identify trouble areas such as cracked plumbing stacks and half-full pitch pans – issues easily corrected if found early.
