In Downtown Ottawa (ON, Canada), roofs endure over 200 cm of annual snowfall, frequent freeze-thaw cycles, and summer UV exposure above 30°C. These conditions can cause ponding water, cracking, and structural fatigue. Poorly designed systems risk operational downtime and water overflow affecting neighbouring properties.
Plrepairsottawa addresses these challenges with EPDM, TPO, and modified bitumen membranes, ensuring durability and thermal performance. Our knowledge spans HVAC integration, solar panel readiness, and compliance with Ontario Fire Code—customised for Ottawa’s unique climate and urban demands.

Accurate Commercial Roof Installations
A successful roof starts with precise installation. Our process ensures:
- Thermal insulation ratings meet or exceed R-30 standards, improving energy efficiency by up to 25%.
- Vapour barriers are installed to eliminate moisture intrusion, preventing condensation damage.
- Use of mechanically fastened systems for superior wind uplift resistance, verified through ANSI/SPRI ES-1 testing.
- Incorporation of reflective cool roofing materials, which can reduce rooftop temperatures by up to 50%, lowering HVAC loads.
- Deployment of CAD modelling for pre-construction planning, ensuring accurate material usage and cost control.


Specialist Commercial Roof Repairs
Every repair is meticulously planned and executed using advanced diagnostic tools and materials:
- Infrared thermal imaging locates subsurface moisture with 98% accuracy.
- Polyurethane liquid-applied membranes provide smooth, flexible repairs ideal for high-movement areas.
- Replacement of failed fasteners and corroded metal flashing, prolonging roof lifespan by an average of 7–10 years.
- Application of elastomeric roof coatings, delivering up to 80% reflectivity and extending the existing roof’s life by over a decade.
Customised Roof Maintenance Plans
Routine maintenance is key to preventing costly issues. Our plans include:
- Bi-annual inspections, focusing on high-risk areas like drains, parapet walls, and membrane seams.
- Core sampling to assess substrate conditions and identify early signs of wear or damage.
- Complete moisture surveys to detect hidden leaks and trapped water in multi-layer systems.
- Use of pressure washing and eco-friendly cleaning agents to clear debris, algae, and dirt that compromise reflectivity and waterproofing.


24/7 Emergency Roofing Services
Unexpected issues demand immediate solutions. We deliver:
- Water intrusion management, utilising reinforced tarps and quick-curing patching systems to mitigate operational losses.
- Deployment of high-capacity dehumidifiers to address interior water damage following leaks.
- On-the-spot ballast reinstallation for loose or shifted roofing aggregate after storms.
Customised Solutions for Industry-Specific Needs
We work with various industries, understanding the nuances of their roofing demands:
- Retail Spaces: Installation of energy-efficient, low-maintenance roofing that supports branding through colour and design integration.
- Industrial Facilities: Chemical-resistant membranes like CSPE (Chlorosulfonated Polyethylene) for environments exposed to corrosive substances.
- Office Buildings: Advanced spray polyurethane foam systems (SPF) to maximise insulation and minimise air leakage.
Our services are designed with precision and longevity in mind, ensuring every roofing solution in Downtown Ottawa is specific to meet the region’s unique challenges.

Common Roofing Problems in Downtown Ottawa And How We Solve
Downtown Ottawa’s unique climate can take a toll on roofs, leading to common issues like leaks, damaged shingles, and poor insulation. Addressing these problems promptly is essential to maintaining the safety and efficiency of your property. Our expert roofing solutions ensure long-lasting results in Downtown Ottawa as below.
Ice Dams and Snow Loads
Snow and ice can wreak havoc on commercial roofs in Downtown Ottawa, causing structural stress and water ingress. We utilise:
- Heat tracing cables that maintain consistent temperature along critical areas to prevent ice buildup.
- High-capacity scuppers and gutters, designed to handle heavy snowmelt and rainwater runoff, reducing the risk of overflow.
- Load-rated structural assessments, ensuring your roof can withstand snow accumulation as per CSA S157 standards.


Water Ponding on Flat Roofs
Standing water can degrade membranes and compromise the roof deck. We address this with:
- Installation of tapered insulation boards, ensuring effective water drainage without disrupting the roof’s overall integrity.
- Cricket and saddle systems to direct water toward drains and scuppers in low-slope areas.
- Application of polyurethane coatings, which resist water penetration even in areas prone to minor ponding.
Ageing Membrane Systems
Older membranes lose flexibility and resistance to environmental stressors over time. We modernise these systems by:
- Replacing them with PVC or TPO membranes that offer enhanced puncture resistance and energy efficiency.
- Conducting substrate evaluations to address underlying deck issues before reinstallation.
- Using mechanical fastening systems or ballast-based anchoring to extend the roof’s lifespan without adding unnecessary weight.


HVAC and Equipment Integration
Rooftop units often compromise membrane integrity, leading to leaks and wear. Our solutions include:
- Custom fabricated flashings that seal penetrations around equipment bases.
- Use of vibration-dampening supports to minimise stress on roofing materials.
- Re-sealing and reinforcing areas with self-adhering membranes, providing additional protection against leaks caused by movement or vibration.
Seam Failures in Single-Ply Membranes
Improperly sealed seams are a common cause of leaks in commercial roofs. We resolve these issues with:
- Hot air welding to create strong, continuous bonds in areas where adhesives fail.
- Seam reinforcements using pre-fabricated tape systems for extra durability in high-stress zones.
- Comprehensive seam inspections with vacuum testing equipment to identify and address weak points before they become problems.


UV Degradation and Thermal Cracking
Intense UV radiation and temperature fluctuations can cause roof materials to degrade. We combat this by:
- Applying high-SRI (Solar Reflectance Index) coatings to reflect sunlight and reduce surface temperature.
- Using UV-stabilised membranes like TPO, which maintain flexibility and resist cracking even in extreme conditions.
- Conducting thermal scans to identify early signs of degradation and recommend timely interventions.
By addressing these common roofing problems with technical precision, we ensure your Downtown Ottawa property stays protected year-round.
