Commercial roofing Mississauga

A leaking commercial roof is an enormous liability, both in terms of structural damage and human health. Water damage can rot away at walls, ceilings, and floors, making the building unsafe for work. It also promotes the growth of mold, which can cause serious health issues if left unchecked.

As the owner of a commercial building, you face the difficult balancing act of ensuring that you spend as little as possible on your roof while maintaining optimal function. We at Top Roofing Contractors Inc. understand this dilemma and can

Commercial roof leaks are often frustrating, especially when they occur in areas that are seen by your customers or clients. Our team offers quick and easy roof leak repair services in the Greater Toronto Area and can arrive at a time that is convenient for you.

The Challenges of Commercial Flat Roofing

Unlike sloped roofs, flat roofs don’t have an easy way to shed excess water. Many flat roofs will have slight slopes leading to drainage systems, but someone must install and maintain them to ensure that they function correctly. Any damage to the roof will lead to pooling water, which, in turn, will cause further problems.

Water Pooling

Water pooling becomes a problem if your roof can’t shed the water within 48 hours of rainfall or snow. It’s enough time for water to start finding cracks in your roofing material and begin the cycle of water damage. The situation is even worse in winter when this water refreezes and expands.

Pooled water also promotes the growth of algae, which can eat away at many common roofing materials, further exacerbating the damage to the roof.

UV Exposure

Materials such as TPO, EPDM, and elastomeric membranes are susceptible to UV and heat damage. Constant exposure to the sun will cause the material to become brittle and crack, allowing water to seep in after heavy rains. Calling Quality Roofers to make regular checks is essential to ensure that your roofing material continues working as intended.

    Types of Flat Roofing Material

    Whether you’re installing a roof on a new building or replacing your existing roof, you need to make an informed decision about the roofing material you want to use. Modern technological advances have expanded the range of roofing materials available, and it’s essential to evaluate their suitability for your needs.  

    As roofing experts, Quality Roofers is also always on hand to provide you with valuable advice. We understand the Mississauga climate and its effect on commercial flat roofs—and which materials are best for specific situations. Don’t hesitate to get in touch with us about any roofing questions you may have.

    Gravel and bitumen

    One of the oldest roofing materials, layers of bitumen (tar) and gravel provide a robust roofing solution. This method is an affordable solution that requires moderate maintenance and can last up to 30 years if properly maintained.

    Unfortunately, this type of roof is neither energy-efficient nor eco-friendly. If you often use heating or cooling in your building, you may spend more on HVAC costs than what you save with this roof installation.

    Elastomeric membrane

    Elastomeric membrane is a material that we apply directly onto the roof and melt into place. It has a sturdy, clean finish that is resistant to weather damage. It’s also watertight and requires minimal maintenance. 

    The main drawback of this material is that we contractors must have a special installation permit to work with the material. If you do opt for this material, however, you can expect it to last up to 35 years with proper maintenance.

    TPO and EPDM

    Some of the most popular roofing materials are thermoplastic polyolefin (TPO) and ethylene propylene diene terpolymer (EPDM). They are environmentally friendly, energy-efficient, and more affordable than elastomeric membranes due to their ease of installation.

    While the stated lifespan of these materials is around 30 years, they are prone to tearing and may require more maintenance than other roofing materials.

    Sheet Metal

    While more expensive than other roofing materials, sheet metal offers several advantages to offset the high initial cost. It has a lifetime of 50 years, is incredibly durable and weather-resistant, and reflects away the sun’s heat, resulting in lowered energy bills in summer.

    Signs Your Roof Needs Replacing

    Regular maintenance is essential for getting the best performance out of your roof, but even the best maintenance schedule can’t combat ageing. When your roof starts approaching the end of its lifespan, it will be significantly more prone to leaks and water damage. 

    At some point, the cost of repairs will become prohibitive, indicating that you need to consider a roof replacement. 

    Whenever you call us at Quality Roofers, we’ll thoroughly evaluate your roof’s condition and give our honest assessment about repairs and replacements. 

    Some of the warning signs that your roof is in trouble include:

    • The roofing materials appear brittle, crumbly, old, or damaged
    • You can detect roof leaks in the attic
    • The roof structure is caving in due to insufficient framing support
    • The humidity is high in the attic, especially if the rest of the building is dry
    • Clear signs of water damage and pooling are visible

    Our Approach to Roofing at Quality Roofers

    Most building owners don’t pay much attention to their roof until a problem develops. Unfortunately, this approach ends up costing more money in the long run due to issues remaining undetected until they are severe enough for you to notice. 

    For instance, your roofing material will show damage long before any roof leaks appear in the building. At that point, you can expect costly repairs to both the roof material and the building, instead of just having to fix a spot of damaged roofing material.

    Our alternative is to recommend regular inspections and scheduled maintenance. Our experienced crew can detect even small faults in your roof and repair them immediately, resulting in cheaper repairs and significantly less down-time for the building.

    We can schedule inspections on an annual, half-yearly, or quarterly basis, depending on the age and state of your roof. During these inspections, we examine both the interior and exterior of the roof and look for indicators of surface damage, problems with drainage, and water accumulation. 

    It’s also important to note that while roofing manufacturers offer warranties on their roofs, these warranties often come only with the condition of regular maintenance requirements. Falling behind schedule may result in losing your warranty, even if the roof did truly have a flaw.

    It’s in your best interest to conduct regular maintenance on your roof. The costs for an inspection and minor repairs are negligible compared to new roof installation or repairs to the entire building.

    Your Fully Insured Commercial Roofing Company

    When you start looking around for a roofing contractor, don’t fall for prices that are too good to be true. Always do your research and make sure to work with a company that is fully insured and certified. If you don’t, you may end up liable for accident or damage costs that may take years to resolve.

    As Mississauga’s premier commercial flat roofing company, at Quality Roofers, we believe in generating value for our commercial clients. We’ve spent years building up our reputation as one of the best companies by developing real relationships with our customers. 

    Your building is a valuable investment, and your roof is the first line of defence. Instead of calling us when things go wrong, consider calling us to schedule a routine inspection or preventative maintenance. We offer competitive rates, are fully insured, and have the expertise to keep your roof performing optimally for years to come. Please call us at Quality Roofers today.
