Why cool roofs matter for Montreal properties
High-SRI membranes reduce cooling costs, extend roof lifespan, and improve comfort for residents. Montreal's cool roof standards exist to combat urban heat and lower energy consumption across the city.
Lower cooling costs
Reduced surface temperatures mean less air conditioning demand and measurable energy savings year after year.
Extended membrane life
Cooler roofs experience less thermal stress, reducing material degradation and extending the lifespan of your restoration.
What the Solar Reflectance Index measures
SRI is the standard metric for how much solar heat a roofing material reflects back into the atmosphere. Higher SRI values mean cooler roof surfaces and lower building cooling loads.
Reflects solar radiation away
Reduces surface temperature significantly
Improves building energy performance
Questions
Common questions about SRI compliance, permits, and restoration under Montreal by-laws.
Solar Reflectance Index measures how much solar heat a roofing material reflects back into the atmosphere on a scale of 0 to 100. Higher values mean cooler roof surfaces and lower cooling costs for your building.
Montreal enforces SRI minimums across multiple boroughs including Plateau Mont-Royal, Ville-Marie, Outremont, and others. Contact us to confirm your specific borough's requirements.
