What problems are caused by poor attic insulation?

In Quebec, the effects of poor attic insulation are constant. In winter, your home loses heat, which leads to the formation of frost in the attic, ice on the roof and sometimes even under the cladding. In this case, it is essential to repair the insulation in the roof and prevent heat loss.

Whether it be streaks on the interior walls, peeling paint, mold, ice build-up on the roof, uncomfortable or unstable temperature in your home, high heating and air conditioning costs, look no further: your attic insulation is failing.

The good news is that you have found the cause of your worries. The bad news is that you won't have the know-how to ensure lasting renovations. No need to panic, contact Les Couvreurs Duro-Toit. Our team is certified by the Régie du bâtiment du Québec and has the experience and training necessary to maximize your home's comfort. After intervention, they will give you the best advice to maintain your roof and increase its longevity.

Why hire Les Couvreurs Duro-Toit for your attic insulation?

No matter how your roof is configured, our technical team will know the best way to provide you with high-performance roof insulation. Upon their inspection, they will verify the watertightness of your roof and assess the efficiency of the attic ventilation and insulation system.

Following this, our experts can suggest adding insulation or replacing the entire attic insulation system. In the case of the first solution, our team will add wool on top of the existing roof insulation. This helps increase the R factor and make ventilation the key to an efficient roof. In major cases, the insulation materials from the roof will have to be removed and replaced with other materials more resistant to heat movement.

Whether you need to install a vapour barrier (6 mm polyethylene) with overlap, replace the existing roof insulation material with spray polyurethane or blown wool, verify that the roof insulation's R factor is suitable, or ventilate the attic space, our roofers can perform all of these technical tasks flawlessly, using high-quality materials.
