Flat Roofing In Toronto

For flat roofing in Toronto, you don’t have to look far. Search the internet and you will notice many Toronto roofing companies who list flat roofing as one of their services. Flat roofing is a popular choice for industrial, commercial and office buildings because it is more efficient to build a flat roof than a pitched roof. HVAC equipment is an important part of any building’s systems, especially in climates tat experience extremes of heat and cold, like Toronto’s. Flat roofs allow that equipment to be placed on the roof instead of inside the building where they would take up valuable floor space.

Climate is a big reason for using flat roofs on Toronto buildings. Flat roof insulation helps reduce the cost of heating the building in winter and cooling it in summer. If is not as easy to insulate a pitched roof. Contrary to popular belief, a properly built and maintained industrial flat roof will drain water well and will not have a major problem with snow during Toronto’s winters.

Maintenance is an important part of the lifespan of any flat roof, particularly because of the extremes of Toronto’s weather. A properly maintained flat roof will last many years longer than one that is not as well maintained. Flat roof maintenance needs to be carried out by roofing professionals and, as mentioned previously, there are a number of roofing companies that maintain flat roofs in Toronto and the GTA.

Usually, the first sign of a flat roof maintenance problem is a leak that is large enough to be spotted inside the building. Unfortunately, by the time someone spots a flat roof leak, some sort of damage has already occurred, either to the roof, building or the contents of the building. A proactive flat roof maintenance program will identify potential problems and correct them before any real damage is done. Companies that maintain flat roofing in Toronto understand how the climate can affect them, and they know the symptoms to look for and how to fix the problems that those symptoms expose.

Flat roofs in Toronto can face a number of problems. Early identification and repair of any of them will extend the lifespan of the flat roof. Roof membrane blisters occur when voids in the layers of your flat roof begin to fill with gas after repeated cycles of heat and cold, which can occur within a single day, when hot days are followed by cool nights. Small blisters are usually not a problem and most flat roofs have small undetected blisters that may never be a problem. Larger blisters need to be watched and corrected before they force protective coatings and gravel off the blister to expose the roofing felts underneath. When that happens, the roof will deteriorate much faster at that spot and increase the chances of allowing moisture underneath the roofing layers and into the building.

Another flat roof problem caused by the expansion and contraction that results from Toronto’s weather extremes is pressure ridging. In the heat of summer, roof membranes expand and on cool nights, or in winter, they contract. Flat roofs are constructed to handle a certain amount of expansion and contraction, but over time, repeated cycles of severe expansion and contraction causes adjacent roof membranes to push against each other and form ridges. Left untreated, the ridges can crack and allow moisture to enter.

Perhaps the most identifiable problem with flat roofing, and one that occurs everywhere as much as in Toronto, is pooling of water. Industrial flat roofing is designed with built in slopes to allow water to drain away. No flat roof is perfect and, especially in heavy rains, some water pooling is expected. However, water that remains on a flat roof 72 hours following a rain is an indication of a problem.
