Questions and Answers

How can I extend the life of my roofing system?

Regular roof maintenance can prevent roof degradation and extend its lifetime. Here are a few regular maintenance tasks and suggestions for taking care of your investment:

1. Regularly inspect and clean drains to avoid increased roof weight load from standing water.
2. Keep petroleum-based products off the roofing system membrane.
3. Install a grease pan around an active kitchen vent.
4. Minimize foot traffic.
5. Remove leaves and debris from the roof with a soft broom or leaf blowers.
6. Inspect the roofing system at least every 2 years. Check for blisters, protrusions, missing caulking, debris, moss, etc.
7. Remove snow after a heavy snowfall. (This action should be performed by the roofing contractor so as not to affect any warranty remaining.)
8. Install and clean gutters (before the rain season begins and after all the leaves have fallen). To save time, coordinate down pipe flushing with gutter cleaning.

How can I tell if my roof is leaking?

Any of the following signs may be indicative of a leaky roof:

* Standing water
* Mold
* Wet spots on floor
* Soft or sagging ceiling
* Damp ceiling and/or wall area(s)
* Water spots or brown water rings on ceiling

If you do find a leak, repair it as soon as possible in order to minimize or prevent internal damage to the building structure.

I have a re-appearing damp spot on my basement floor. What could be the cause?

Damp spots on a basement floor or a foundation wall that never seems to dry could signify a cracked or blocked drain tile. Drain tiles collect ground water from the outside and redirect it away from a building’s foundation. But if the tile is cracked or damaged, water can leech through concrete foundation walls and floors. If the problem is caused by damaged or blocked tiles, consider flushing or replacing the damaged section of drain tiles.

What are the benefits of installing roof ventilation systems?

During periods of warm temperatures, roof ventilation systems remove heat by moving air through the roof space, keeping the building cooler. In periods of cool temperatures, ventilation systems remove trapped moisture from a building with a steady flow of fresh, dry air.

What does a typical Cambie Roofing and Drainage site inspection involve?

During a site inspection, a Cambie Roofing and Drainage roofing expert will check the following structural roofing elements:

* Fascia – for splitting, rusting, felt deterioration, punctures and fastener failure
* Flashing – for punctures, deterioration, blistering and open laps
* Expansion Joint Covers – for open joints, punctures, rusting, etc.
* Gum/Pitch Pans – for fill material shrinkage
* Roof Penetrations – for open laps and punctures
* Roof Drains – for overflows or blockage

Site inspections will also include a check on the condition of the roof’s surface, membrane and general overall appearance, as well as intersecting roof planes, equipment housing, soil stacks, valleys and ventilation.
