Storm-Proofing Your Ottawa Business: Summer Commercial Roofing Guide

Markelangelo's ( • July 7, 2026

Summer in Ottawa brings both beautiful blue skies and unpredictable storms. For business owners, this isn’t just a matter of weather—it's a call to protect your property investment and ensure uninterrupted operations. As Ottawa’s commercial roofing experts, Markelangelo’s is here to help you navigate summer’s unique challenges, from intense sun and humidity to sudden thunderstorms and high winds. In this guide, we share practical strategies to storm-proof your commercial roof, safeguard your assets, and keep your business thriving.


Why Commercial Roofs Need Special Attention in Ottawa’s Summer


Ottawa’s climate is known for its dramatic shifts. After a long winter, summer storms can hit hard, assaulting commercial rooftops with torrential rain, gusty winds, and even the rare hailstorm. Flat roofing systems commonly found in local businesses, such as TPO, EPDM, and PVC, must withstand heavy downpours while reflecting intense UV rays. Ignoring seasonal maintenance can lead to issues like ponding water, weakened seams, and undetected leaks—all of which can damage your property and disrupt business.


Is Summer Storm Damage Really That Common for Ottawa Businesses?


Absolutely. Summer thunderstorm warnings are routine in Ottawa and the surrounding areas, with cases of flash flooding, strong winds, and roof damage making the news every year. Proactive storm-proofing isn’t just smart maintenance—it’s risk management for your business.


Essential Commercial Roofing Maintenance Before Summer Storms


Investing in routine commercial roof inspections and timely repairs is vital, especially heading into summer. Here’s how our Markelangelo’s team ensures Ottawa businesses are storm-ready:


- Comprehensive roof inspections: We look for membrane splits, loose flashing, and blocked drains, especially on flat roofs vulnerable to standing water.

- Gutter and downspout maintenance: Clean and repair gutters to prevent overflow and water intrusion.

- Check and reinforce roof flashing: Secure all edges, seams, and joints to stop wind-driven rain from entering.

- Debris removal: Clear all roof surfaces, as debris can block drainage and become projectiles in high winds.


If small leaks or minor damage are spotted during an inspection, Markelangelo’s recommends fast, professional repair—tiny weaknesses can become major headaches during a heavy downpour.


Choosing the Right Roofing Materials for Ottawa’s Storms


Ottawa’s variable summer weather demands reliable commercial roofing materials. Some of our top recommendations include:


- TPO Roofing: Highly reflective, energy efficient, and strong against ponding water.

- EPDM Membrane: Durable, flexible, and weather-resistant, making it ideal for Ottawa’s climate.

- Metal Roofing: Excellent for sloped surfaces, offering wind and impact resistance with minimal maintenance.


Our experienced team can guide you through selecting and installing the most storm-resilient roofing system for your Kanata office, Gloucester retail space, or Barrhaven warehouse.


Summer Storm-Proofing Checklist for Ottawa Businesses


Prepare your property now to minimize risk during severe weather incidents. Key steps include:


- Schedule a professional roof inspection before and after major storms.

- Ensure all roof drains, scuppers, and gutters are free from debris.

- Secure loose rooftop equipment such as HVAC units or antennas.

- Document the roof’s condition with photos—critical for speedy insurance claims.

- Consider investing in reinforced flashing, upgraded drainage, and emergency repair kits.
