Roof Repair is repair work of actual leaks and obvious deteriorated areas on an identified, localized basis. Good repair work generally requires highly skilled roofing experience in defect identification and proper repair procedures.

Roof Restoration, or resaturation, is an intermediate step between repair and retrofit, and generally includes a repair procedure for all flashing and a resaturant type liquid with an optional fabric or mat over an entire roof area.

Roof Retrofit, or recover, is refitting the existing roof system with a new membrane cover and all related flashing, over the top of the existing roof membrane. New insulation is generally used to separate the new membrane from the existing membrane.

Reroofing directly over an existing roof membrane is not recommended by many material manufacturers and roofing experts since defects in the old roofing system can be transferred to any new roof covering and there is always a high risk of trapping moisture from the existing roof under the new roof membrane. Complete roof removal eliminates these risks.

Roof Removal and Replacement is the installation of a new membrane system after complete removal of all roof components above the structural deck. This is generally considered the safest and surest method to guarantee long-term performance.

As with the retrofit procedure, an engineering study should be conducted with consideration of component expansion/contraction cycles, roof drainage, vapor retarder requirements, temporary roofing requirements, roof projection flashings, perimeter flashing elevations, structural system loadings, asbestos audit and energy conservation analysis.
