Roof Maintenance & Inspections We recommend annual inspections (as a minimum) for every roof system. Far too often, the cause of a roof failure is the absence of proper maintenance and inspection.

Something that starts out small and very repairable when left unchecked, can turn into a very major roof problem.

Periodic visual roof inspections (especially after storms) and routine maintenance to deficient conditions can increase the long term service life of any roof assembly.

To perform an annual inspection, our qualified roof inspectors walk over the entire roof area looking for and photographing all observed deficiencies.

These observations are then noted on an inspection form along with recommended maintenance procedures to the cited deficiencies.
