Reasons Why Your Commercial Building Roof Is Leaking

There are several reasons why a commercial building roof might leak, including the age of the roof, shingles that are damaged or poor drainage. 


Did you know that water damage is the most common insurance claim in Canada? Your roof is one of the main culprits, allowing a small gap or hole to reap havoc on your property and its contents. So how do you manage to isolate the problem?

There are issues that may cause your roof to start leaking. Read on as we give our reasons why your commercial building roof may be leaking. 


You Have an Older Roof

Even the best roof will weather and wear away with age. Natural degradation along with exposure to the elements will mean that at some point it will need replacing. Regular maintenance can help prolong this, but a time comes when you have to pay out for a new roof. 

When you have a leaking roof, a professional service will be able to advise on the best course of action. They may be able to suggest newer materials and repairs that can prolong its life for a few years more. If this is a false economy and you need a full replacement they will let you know. 


Poor Drainage

Drainage is one of the most important functions of your roof. Without it, water will pool and pond. This can result in a build-up of mould, algae and contribute to faster degradation of the roof. 

Checking your drainage is a large task as several points need to be assessed. The gutter is just one of many. Downspouts, scutters, and drains should also be checked and regularly cleaned to prevent blockages. 


Improper Flashing

Flashing seals joints and bends in the roof. These occur around chimneys, but also on skylights and vents. In the past, tar was used to seal these areas though metal is now more common and effective. 

Melting snow, rainfall, and direct sunlight can degrade the flashing. You can solve the problem by getting flashing replaced. If you have an older building, you should consider upgrading to metal flashing. 


Damaged Shingles

Shingles are the layer that protects your roof from the elements. When they crack, break or move, this layer of protection has a weakness. When water lands on the roof it has an easy way to get inside the building. 


Damaged Membrane

The membrane is the waterproof layer that sits above the insulation. If it is ripped or punctured, it loses its ability to keep water out. This means moisture can get through, seep into the insulation and stay there. 

If this problem is caught before the water gets it, you may be able to fix the area. When water has already managed to get inside you may need to replace large areas of the membrane and insulation.
