Flat Roof Insulation: Stop Losing Energy ... and Money!

According to the Ministère de l’Énergie et des Ressources naturelles du Québec (MERN), You can lose up to 11% of the heat indoors if your flat roof is poorly insulated. That’s bad enough ... but it gets worse! In this article, Couvreurs DM, flat roof specialists (residential and commercial roofing) in Montreal and the surrounding area, explains why you should pay great attention to the insulation of your flat roof.

The Right Roof Insulation Can Reduce Your Heating and Cooling Costs
Construction and renovation experts say poor insulation can push your heating and cooling bill up by 30%. Remember that where there is heat loss, there is necessarily a waste of energy AND money! On the other hand, effective thermal insulation - which takes into account the ventilation space required for optimal air circulation under the roof - promotes better energy consumption, which can significantly lower your heating and cooling costs.

How Do You Know If Your Flat Roof Is Well Insulated?
There are several signs that your roof is poorly insulated. Here's what to watch out for:

  • High heating or cooling costs
  • Walls and floors that remain cold (in winter)
  • Poor heat distribution from room to room
  • A problem of excessive heat inside (in summer)
  • The inefficiency of an air conditioning unit
  • The appearance of mold on the ceilings and walls


If you notice any signs of poor insulation, you must take steps to correct the problem. Do not take any chances because the integrity of your residential or commercial building is at stake!

When Is the Best Time to Improve Your Flat Roof Insulation?
When the time comes to replace your flat roof, take the opportunity to improve the insulation. First, have the strength of the roof structure checked by experts. And above all, entrust your repair work to a master roofer certified by the Commission de la construction du Québec (CCQ).
