Choosing a good roofer.
Does your roofing contractor have WCB and BBB?
- A business accredited with the Better Business Bureau will have ratings and any complaints noted by customers on the companies profile.
- If there are no complaints, that is a good indicator that the roofing company is in good standing with their clients and provide quality workmanship.
- WCB is British Columbia’s workers compensation board. By contacting WCB, you can obtain helpful information regarding the companies safety history or any claims made towards the contractor.
- If you get a good response from WCB the company will likely be a good roofing contractor in Vancouver.
Understanding your Roof
Ice and water shield
Some signs you should look for
Worn, cracked or missing shingles can allow water to enter your home. This is especially true if your roof is more than 10 years old. If water is entering your home in several spots, worn shingles may be the reason.
Flashing is the aluminum or copper metal edging that seals your roof at the edge of walls, chimneys or vent pipes. If the flashing is not properly sealed, or if the seal has dried of pulled away, water can easily enter your home.
A valley is where two flat roof planes meet, forming a v-shape. Valleys should have flashing under the shingles to provide additional protection. If not, water flowing down the valley can seep under the shingles and into the home.
Chimneys are a common source of leaks. The flashing around a chimney is particularly difficult to install properly. If it pulls away even slightly water can pour in and travel to all parts of your attic and, eventually, into your framework, walls and ceilings.
Vents for plumbing or furnace exhausts are also spots to watch for leaks. Flashing here is usually a metal “collar” that can easily pull away or gap.
When snow or ice sits on a roof warmed from within, the lower layer can melt and run down to the edge of the roof, where it refreezes when exposed to frigid air. This forms an “ice dam” that can back up water and allow it to seep into your home.
Wind Blown Rain
Strong winds can actually blow rain horizontally up and under shingles. While this is a rare occasion, it indicates that the shingles are not properly seated or sealed.
Some “roof” leaks are actually a case of improperly sealed siding that allows water to get behind the siding material and into the home.
