Low-slope roofs are generally loved for their modern look. We agree a California-style home, for example, is timeless. However, the tops of this type of home are often challenged by the Quebec climate. This is why we note some common problems associated with this type of roofing.<\/p>\n
The most common problem is water infiltration. Of course, if your roof is not entirely watertight, water can seep under the shingles or tiles, but this risk is increased when the roof’s slope does not allow for natural drainage. For example, water can stagnate around chimneys and eventually make its way into the house.<\/p>\n
If your roof is poorly ventilated, ice dams will likely form in the winter. With a flat roof, the chances of damage to the roof and water seepage are much more significant.<\/p>\n
Like flat roofs, low-slope roofs are vulnerable to the weight of accumulated snow. You will have to ensure that the snow load is not too heavy to affect the structure of your building. Snow removal on these roofs is even riskier than on flat roofs. You must therefore make sure to respect the safety rules in this regard.<\/p>\n
The best quality\/price ratio for low-slope roofs remains the welded elastomeric membrane which ensures a complete waterproofing of the roof and all its accessories. Several colors are available today that allow a harmonious match with your siding. In addition, if part of your roof is invisible from the street, you could opt for a white roof for the hidden part. A white membrane has several advantages, the main one being that it saves you money on air conditioning in the summer.<\/p>\n
Asphalt shingles and tiles are not recommended, as the possibility of infiltration is too great. Don’t trust people who advise you to use a self-adhesive membrane on the entire roof surface. Unlike a welded elastomeric membrane, it will not guarantee perfect roof waterproofing.<\/p>\n
Do you still prefer the effect of shingles or tiles? It is possible to superimpose these materials over the elastomeric membrane. Consult a specialist for this purpose.<\/p>\n
Many low-slope roofs are poorly ventilated. Ventilation plays an essential role in the roof’s longevity while avoiding the creation of ice dams and mold formation. If necessary, your roofer will suggest blowing the roof to ventilate it properly.<\/p>\n
Although some aspects of a low-slope roof require special attention, it still has the advantage of being easy to access for workers. Generally, the installation time and the number of materials are reduced, saving you money on the total cost.<\/p>\n
