Roof Maintenance

1. Keep the roof surface clean at drains to avoid flow restriction or complete blockage. This will avoid overloading the roof with unnecessary standing water and the resulting weight loads.
2. Keep all petroleum products off the membrane. This includes solvents, greases, oil or any other liquid containing a petroleum product. The majority of roof membranes are severely degraded if prolonged contact has occurred.
3. Kitchen waste should not be exhausted onto any roof surface. If necessary a grease pan must be installed around the active vent.
4. Keep foot traffic to a minimum. Walkways should be provided if regular traffic is required or if roof top equipment has a monthly maintenance schedule.
5. Use a soft corn broom or blower to remove leaves and debris from the roof without disturbing the roof ballast placement.
6. A formal inspection of the roof is recommended approximately every 2-3 years. (A minimal fee is charged for this service so please call to confirm cost). Items to check for include all protrusions, blisters, rusting metals, wind swept areas, caulking re-treatments, gum pan top ups, debris, membrane degradation, excessive moss build up, etc.
7. Unless a heavy snow fall occurs, snow removal is usually not required. If desired, this action should be performed by Cambie Roofing Contractors so as not to effect any warranty remaining.
8. For roofs incorporating the usage of gutters for water removal, these gutters should be cleaned twice a year to facilitate proper drainage and prevention of water backup under the roofing system. Recommended timings are before the rain season begins and after all the leaves have fallen. Coordinating the down pipe flushing responsibility with this gutter cleaning is advantageous.

*Warning: Any temporary/permanent repairs or modifications on the guaranteed roof performed other than by Cambie Roofing Contractors will result in the voiding of any remaining warranty coverage.

Caulking

Caulking maintenance is an item that cannot clearly be scheduled from job site to job site. There is no life expectancy for any caulking due to the variety of usage and varying conditions. Several factors contribute to caulking degradation. Items such as weather history (a long dry summer), exposure (south facing), or usage (around a hot or vibrating object) all affect the life expectancy for a bead of caulking. Therefore we recommend a yearly visual inspection of all caulking locations. If separation is visible, the cracked or dried caulking should first be removed and then replaced with a similar bead of caulking that overlaps the remaining sealant by at least one inch.

The best time to do this annual chore is after the heat of summer and before the rainy season begins. Therefore problem areas can be identified and resolved before a possible leak results. Not all caulking breakdowns will result in leaks however, as in many situations a primary seal has been made somewhere behind the visible caulking sealant.
