We recommend that inspections and condition reports are done at least twice a year. At the end of winter and right after summer are preferable because this is when roofs have passed through the periods of severest stress.
Maintenance reports may recommend:
Gutter cleaning – hanging or built in
Power washing – metal or concrete (not recommended for asphalt or cedar)
Drain cleaning – ensuring all drains are taking water
Caulking maintenance – metal flashing
Debris clean up – vegetation, garbage, animal nests, etc.
Inspections can include (written picture report or verbal):
Roof Condition report
Attic ventilation report
Types of roofing systems:
Tar and gravel
“The most important reason for establishing a program of regular roof maintenance is to protect the owner's investment. A properly executed maintenance program will add years to the life of the roof by detecting minor problems before they become major, as well as providing better protection for, and avoiding interruption of, the internal functions of the building.
A roof system is exposed to all manner of chemical and physical stress. The long term effects of these forces are called "Normal Aging". In reality, small isolated problems caused through abuse, stress concentration, inadequate ventilation, error, or other factors result in a shortened lifespan of the roofing system.
Small problems or defects, if not detected and repaired, inevitably become major problems affecting the performance of the whole roof system.
Roofs represent approximately 5 to 7% of capital building costs - but roofs cover 100% of the building and its contents” ………….taken from the RCABC maintenance guide
