Buildings are usually constructed to withstand a good accumulation of snow. However, excess weight can compromise the integrity of your roof. To avoid water infiltration, ice blockages and even structural collapse, it is often necessary to clear your roof of snow. At Couvreurs de l'Est, we offer a professional service from roof snow removal to Montreal and Laval. To help you see things more clearly, we have prepared this article for you.
A matter of weight
Of course, a roof in good condition will support a greater weight than a damaged roof. Flat or low-slope roofs are also more sensitive to snow accumulation and therefore need to be cleared more often. When evaluating the amount of snow on your roof, consider the weight of the snow. For example, 15 cm of wet snow can weigh as much as 100 cm (1 m) of powder.
Precipitation resistance thresholds
A roof can generally support 17 to 20 cm of ice, 38 to 43 cm of compact or wet snow, or 70 to 80 cm of fresh snow. Regularly check the amount of snow, especially after a winter storm, heavy precipitation, an episode of freezing rain or mild spells. Do not exceed the load capacity of your roof, as excess snow weight can compromise its structure. So, exercise caution and clear your roof when you have an accumulation of more than 15 cm.Also, make sure roof outlets, such as plumbing vents, remain unobstructed. The accumulation of snow can alter the ventilation of the attic (attic) by obstructing the vents.
Imminent danger
These are signs that your roof is overloaded:
The appearance of cracks on the interior walls;
A deformation of the ceiling;
Unusual crackles;
Water stains on the ceiling or walls;
Doors and windows that are difficult to open or close.
When you notice damage inside your building, call a professional quickly to remove the snow from your roof and determine if repairs are needed.
