Flat roofs that overheat in summer: concrete solutions in Montreal
Table of Contents
Summary
An overheating roof in Montreal is usually caused by a membrane that is too dark or an aging membrane that has lost its reflective capability.
To address this, it is important to have your roofing inspected and repaired. In most cases, re-roofing with a white TPO membrane is the ideal solution to ensure long-term results.
Why does your flat roof overheat in summer?
A dark or aging membrane absorbs more heat
To start, simply having a dark membrane on your roof can create heat issues, and these issues are often worsened when the membrane has aged.
An overly old membrane loses part of its reflective property, which can cause overheating even if the membrane was perfectly suitable when it was installed.
Urban heat islands worsen the issue in Montreal
It is no secret that the island of Montreal has urban heat islands, a term used for metropolitan zones where the temperature is significantly higher than elsewhere.
It is therefore particularly important to avoid an overheating roof in Montreal to reduce the many consequences heat waves can have on the condition of your roof, or even on the interior of your home.
What concrete solutions can fix it?
Inspect the roof’s current condition
Since deterioration can trigger a roof to overheat, if you notice a temperature problem that was not there before, start by getting your roofing inspected.
Repair weak areas before they worsen
Once the inspection is complete, have the weak areas repaired to prevent problems from getting worse.
It is always better to complete the repairs, since a damaged roof can lead to far more serious consequences for the structure.
Replace the membrane with a more reflective option like white TPO
Having grown rapidly in popularity in recent years, the TPO membrane is the ideal solution to avoid an overheating roof in Montreal.
This durable white membrane offers a solar reflectance index often higher than 100, well beyond the index of 78 now required by certain boroughs in the city of Montreal.
