Will a flat roof support the weight of snow and ice in the winter?
Yes! All LINQ roofs, and their supporting truss system, are designed and stamped by engineers. They are constructed to meet or exceed National, Provincial, and Municipal building codes, accounting for the heaviest snow loads. LINQ homes feature steel reinforcement in the walls and roof and are designed to stack up to four storeys high, ensuring they’re strong enough to hold all the snow a Canadian winter can throw at them.
What happens to the heavy snow and/or ice that build up on a flat roof?
Flat roofs are purposely designed to collect and hold winter snow until it melts. This yields several benefits. First, the snow does not slough onto sidewalks, driveways and window wells, avoiding the safety concerns and repeated clean up that comes from large piles of snow sliding off a conventional sloped roof. In fact, some British Columbia municipalities with high snow loads encourage the use of flat roofs, allowing the extension of eaves to within two feet of property line for houses with flat roofs which don’t slough snow. Second, the snow on the roof has an insulation value of approximately R-1 per inch, providing increased thermal insulation for your home through the winter, exactly when you need it!
Are flat roofs really flat?
No. While the parapet around the roof of a LINQ house may make the roof appear to be flat, the slope of our roof (properly known as the pitch) is ~ 10˚, allowing water, or snow and ice melt, to flow through scuppers installed in specifically designed locations and into the drain system.
Will my flat roof be more prone to leaks?
No. A properly designed flat roof system acts like a swimming pool, capturing all water and snow, and directing water to the built in drainage system. All roofs, whether sloped, flat or anything in between, have the potential to leak over time, if not correctly maintained. The keys to prevention of roof leaks are good design, high-quality materials, proper installation and maintenance.
LINQ’s flat roofs are specifically engineered to prevent leaks. Our manufacturers have extensive experience in the construction and installation of flat roofing systems. Lastly, the use of commercial grade construction materials in LINQ homes means a higher quality roof with far less potential problems than a typical house.
Will my flat roof require more costly maintenance than a conventional roof?
No. All roofs should be inspected annually and maintained on a routine basis. Flat roofs provide ease of access for inspection and maintenance compared to sloped roofs. The roof drains should be cleaned each spring and autumn to prevent blockage and pooling. The effort required to maintain and clean a flat roof is similar to the regular gutter maintenance required for a sloped roof.
