Even if you know that the materials and services provided for your residential roofing are outstanding, emergency roof repairs may still be inevitable. These repairs usually occur during winter, where there’s an occurrence of extreme wind and hailstorms. [Read more…]
As temperatures on the Lower Mainland begin to fall and the cost for residential electricity continues to rise, many homeowners begin to think about the expense associated with keeping their homes cozy during the winter. Unfortunately, this is often a losing battle because many homes are poorly prepared for cold weather. Drafty windows, leaky roofs, and lack of insulation are all energy-wasting problems that can easily be remedied by the do-it-yourself homeowner. Here are a few tips on weatherizing important areas of your home for winter.
• Roof & guttering. Problems with your roof and gutters can remain hidden until winter, when snow and cold temperatures can cause a situation known as ice damming. An ice dam forms due to uneven surface temperatures on the roof, and causes snowmelt to be forced back up and under shingles and into your home. To guard against ice damming, be sure to replace missing roof shingles or tiles, repair leaks and thoroughly clean out gutters to allow runoff to easily flow away from the home.
• Windows and doors. Old single-pane windows are common culprits of heat loss. If you cannot afford to replace older windows and doors with energy-efficient models now, try methods such as caulking around window and door frames, filling large cracks with expandable spray foam insulation, and applying air blockers like shrink wrap and weatherstripping.
• Attic. In addition to preventing ice dams, adequate attic insulation keeps warm air inside your home. Insulation can easily be rolled between floor joists to boost coverage.

The time to think about ice is before winter sets in and temperatures in the Lower Mainland plummet on a daily basis. In particular, now is the time to work to head off “ice dams” that may form on your roofing in Vancouver this winter, causing significant and expensive damage.
An ice dam forms when the roof deck of your Vancouver area home is warmed by the sun or heat rising from your home’s interior. This melts the snow covering your roof from the bottom up. The melted snow runs down to the edge of the roof where it is again exposed to frigid air and refreezes, either on the roof edge or in a clogged gutter. When an ice dam forms, the additional snowmelt that runs down your roof has no place to go except to be forced back up and under your roof shingles and into the home. Once water gets into your home it can travel anywhere — along the rafters, across ceilings, down walls and even into the basement. The resulting damage can be extensive and expensive, with symptoms including rotted wood, mold, mildew, stains and cracked foundations.
The cause of ice dams is not actually the roof, but the attic that lies beneath. If your attic gets too warm, it heats up the roof deck and causes the snow to melt. The secret to preventing this is to lower the temperature in your attic to match that of the roof. There are two ways to do this, and we recommend using both of them. The first is to install a full-length ridge vent along the peak of your roof. This allows air to circulate under the roof deck and not only prevents freezing, but also helps to avoid the build-up of moisture in the attic.
The second step is to install adequate insulation on the floor of your attic. The insulation should not be directly attached to the underside of the roof deck. Good insulation will keep warm air from your home from rising up to the roof and heating the roof deck, thus causing the accumulated snow to melt. There is an added bonus, as insulation can also help reduce your heating costs.
The best time to take these steps is before the first snow falls on roofing in Vancouver! Ice dams can form without you even knowing it and may not become obvious until the damage is done.
