Emergency Roof Repair and What to do if You Have a Leaky Roof. 

If you notice a roof leak, do not delay and give us a call immediately. The safety of your tenants, patrons, and staff is paramount. Dead weight on a low slope or flat roof must be dealt with as soon as possible. Cracking or popping sounds coming from the roof are obvious signs of potential collapse. Ice and snow buildup, or water weight from incorrect drainage are other potential causes of leaks.

While waiting for our technicians to arrive, dry any water inside of your building from the windows, walls, and floor. Moisture buildup can be hazardous as it provides ideal conditions for mold growth. Poking a hole into a swollen ceiling can also alleviate pressure. Use pails to collect dripping water, and mops/towels to dry water on the floor.

It is better to wait for a trained professional to remove flat roof snow or to unplug any downspouts and/or drains. 

The key to a healthy roof is regular maintenance. In particular, we recommend having flat roofs inspected at least twice a year.

The rule for steep roofs is to have an inspection and maintenance performed every three years, although we strongly recommend following up annually.

Are your roof repair services being performed by trade professionals?

The roofing industry, as with other trades, consists of contractors who run their businesses from the back of their trucks, up to larger, corporate players who run international firms. Our first instinct for choosing a service for roof repairs is to ask our networks: friends, family, co-workers, etc. Often, these problems are seasonal, and we trust that a reasonable price coupled with a good word from someone in our network is sufficient to trust the contractor we sign up with.

However, while we may initially receive positive reviews about a company, small up to larger sized enterprises often change staff. You are never guaranteed that you will be dealing with the same roofing crew that had received a positive review for previous repair work.

Check out our staff article on how to choose the right roofing contractor. Roof repairs are a significant investment, and should only be undertaken by an accredited authority with expert trade credentials and significant liability insurance. Verifying your contractor's portfolio, credentials, and compliance with local laws and standards should simply be a matter of a quick web search or asking them to provide with you the pertinent documentation.

Toronto Climate

Approximately 10,000 m below sea level, the Toronto climate is typically temperate, with very well-defined boundaries in terms of roofing seasons. Snowfall begins near the end of November, and the spring melt begins around February. With a many clients residing on, or in the proximity of, the coast of the Great Lakes, there are a number of climate and region-specific roofing scenarios that we must consider before our clients elect a system to invest in.

Leak Tracing

Toronto has historically been susceptible to severe rainstorms, hail, and lightning. Last year, the city’s infrastructure committee, discussing Toronto’s capability to weather storms, said that “Toronto not built for severe rainstorms” (Source: CBC).

Our emergency services are available 24 hours a day throughout the year, including holidays. We have a proven track record of mitigating and performing “live” repairs for commercial and industrial clients, where every minute means a cease in operations and significant losses in revenue.

Even during seasons where there is typical rainfall, Toronto’s roofing and infrastructure has meant that roof leaks are a reality for many proprietors. Particularly in downtown Toronto, repairs of this nature should not be left to local staff or building managers. Even if you carry liability insurance, leak tracing is a component of a Red Seal roofer’s experience and education. It is classified as a technical pursuit and requires the services of a senior Journeyman roofer. Although initial inspections “by eye” can reveal superficial problems, it is not entirely obvious what path a leak will take following rainfalls or storms, or whether this is a problem with drainage, sloping, building envelope and structural problems, etc. Refer to the photo below of a commercial plaza on King St. in Downtown Toronto which shows signs of heavy water ponding and staining. These conditions inevitably culminate into leaks and water damage in the building envelope and structure.

Our trained and certified roofing experts are qualified and carry the proper protective equipment to undertake leak tracing in Toronto, whether you own a high-rise building or a residential property by the water. Ask us for our portfolio and experience in handling damage caused by storms and natural disasters.

Wind Conditions

Another point of interest concerning Toronto is the high winds it experiences. Toronto experiences, on average, 22 days of high winds, averaging about 15 km/h. These speeds rank among the most consistent in Canada. During the spring and summer months, the highest recorded winds went up to 129 km/h (Source: The Weather Network). In terms of roof repair, the building envelope and general engineering of buildings in metropolitan cores should be fashioned to handle a predetermined wind and structural load.

Over time, high-rise buildings experience movement and stress caused by high winds. One vital piece of our comprehensive roof repair offerings also includes building envelope and structural engineering contractor services. We offer certified inspections by professional engineers who can ensure that your commercial high-rise is in compliance with the metrics necessary for withstanding structural loads and high wind conditions.

The building envelope is also a vital component as it pertains to roof leaks. Historically, high wind performance of office building envelopes has been poor (Source: National Institute of Building Sciences). The same is true in Toronto. We offer a number of disciplines as it pertains to the building envelope, for systems such as: flat and low slope roofing, sheet metal, and steep slopes. If your building also has “architectural style” design features, we also provide services for rain screens, rendered façade systems, glazed curtain walling, composite walls, and cladding. 

Cool Roofing

With average highs reaching 25 degrees Celsius, and a spring/summer season holding out from February to mid-September, cool roofing has become a popular choice for metropolitan Toronto. In fact, the City of Toronto offers an “Eco-Roof Incentive Program” for industrial, commercial, and residential buildings. Refer to the photo below for an example of two adjacent commercial high rise buildings in Old Toronto, on the corner of Adelaide St. and Bay St., that have taken advantage of this program.

Our company is in a unique position, as we have been installing reflective systems onto client roofs since our inception. We consistently exceed the mandated 90% reflectivity ratings set by Energy Star and Cool Roof Rating Council. The Red Seal roofers we employ are experts in the elastomeric technology we use for roof repairs and recoveries of cool roofs.

We employ a proprietary methodology to install and repair reflective roofs.  This process works for flat roofing systems including modified bitumen and single-ply synthetic systems. In terms of precipitation, our coatings are completely waterproof, and are afforded further protection by the lower layer which constitutes the roofing membrane. For instance, a commercial roof experiencing foot traffic during maintenance (e.g. HVAC technicians), as well as being situated close to the coastline, would do well with a synthetic EPDM membrane. In this case, not only is your building saving on energy, but its waterproofing features given by a synthetic membrane conforms to the rainfall one would expect during Toronto’s rainy season.
