How to decide between Repairing and Replacing your Flat Roof

.

Are you confused about whether to repair or replace your Toronto residential flat roof? Without a doubt, trying to figure out the best course of action when facing flat roof damages can be such a dilemma. In the short-term, it’s cheaper to repair your roof. On the other hand, if the roof has enough damages already, continuing to repair it can become a pointless and never-ending exercise.

Thankfully, most of the indicators for flat roof repair will be clear for anyone to see. So ensure to conduct routine visual inspections of the roof, taking note of anything that seems out of place, whether big or small. Here are a couple of signs to look out for: 

Blistering, bubbling, or cracking

Blisters, bubble, and cracks normally get caused by moisture trapped below the roof’s surface. On a warm day, this moisture gets heated up as it’s traveling through from above or below the roof surface. The heat makes the volume of water to exceed the permeability of the roof’s coating film or roof ply, which forces the coating to separate at its weakest points, creating blisters. 

Sagging

A sagging flat roof ceiling is a result of a change in your roof’s surface level. It usually emanates from moisture accumulation or added weight to the flat roof. If a flat roof carries more weight than it’s intended to, the structure will inevitably dip. 

Mildew and mould

Your flat roof is suffering from mould and mildew if you notice black spots, stains, and discolouration on your ceiling and walls. The growth of mould and mildew gets catalyzed by the moisture buildup caused by water seeping through the roof into the building’s interior.
