Commercial Metal Roofing

Built for Performance. Trusted Across Ottawa.

Markelangelo’s delivers roofing systems built for Ottawa’s business environment. Our metal roofs are engineered for maximum durability, energy efficiency, and long-term ROI. We install standing seam, corrugated, and architectural panels designed to withstand snow loads, wind, and freeze-thaw cycles—ideal for retail buildings, warehouses, institutions, and industrial properties.

Commercial Shingle Roofing

Smart Protection for Low-Slope & Steep Commercial Roofs

Asphalt shingles remain a reliable and cost-effective choice for many small-to-medium commercial properties, including office buildings, rental units, churches, and retail locations. We use commercial-grade shingles designed to resist wind, water, and UV exposure—installed by certified professionals on time and on budget.

Commercial Flat Roofing

Dependable Flat Roofing for Warehouses, Institutions & More

Flat roofing is a staple in commercial construction, offering efficient use of space, lower material costs, and simplified maintenance. We install TPO, EPDM, and modified bitumen systems for buildings that demand strength, insulation, and weatherproofing. Ideal for schools, hospitals, warehouses, and large retail sites.

Don’t Let Roof Problems Interrupt Your Business

Leaks, membrane failures, aging shingles, or structural issues can cost thousands in repairs, downtime, and liability. A properly installed commercial roofing system ensures your building is protected, your tenants or staff are safe, and your operations stay on track.

I'm so happy with my new roof! From the estimate through the final inspection, it was a great experience. Ladies in particular, if you're tired of trades people treating you like you know nothing, these guys are worth reaching out to. I was treated with respect through the whole experience. Where the weather has been making scheduling quite changeable and challenging, the crew stayed until after 6pm on a Friday to get the job done while the weather was good. Clean up was excellent. Highly recommend! Thank you Markelangelo's.

I recently had Markelangelo’s Roofing to do a minor repair to my roof ,which they originally had installed years ago and to also install a gutter leaf guard. Through the whole process I was impressed with the service,ongoing communication and the work of professional and knowledgeable employees. In this day and age when you do not know who to trust and there are so many scams ,it is comforting to know that there are still good companies who strive to please their customers , do a professional job and on time.They even thank their customers in a sweet way.Trustworthiness ,reliability and the work done at a reasonable cost are key.I do not hesitate to support Markelangelo’s Roofing for having honoured their warranty and demonstrating their professionalism.Thank you!

As a senior operations manager, I am impressed with Markelangelo! I needed to get our roof fixed as it was missing a few shingles but was dreading the process and finding the right company. My expectations were high for quality work and no waiting on the phone and the goal was to find a company in the east end that would quickly provide a quote and get the work completed. It took 5 days from the initial phone call to getting the roof fixed, incredible! Excellent customer service, throughout the entire process from getting a quote to receiving a completion report and invoice payment! Markelangelo raises the bar for customer service excellency in Ottawa!

My landlord hired Markelangelo's for full replacement and I must say that the condition that they left the exterior of our home was immaculate and very appreciated!
Thank you to all your roofers for going above and beyond 🙂

As old bathroom exhaust vents to outside did not seem to work, I am happy to see new insulated vents exhaust to the roof as a permanent solution. Thanks for a job well done!

I hired Markelangelo's for a roof repair - I had a gable roof and a couple of roof vents that needed repairing. I couldn't be happier with the entire process: everything from the initial call, the estimator and the roofer who did the work were top notch. Price was excellent and the estimator was able to give me a quote on the spot. I signed digitally and had the roof repaired the following week.

I would recommend to anyone in Orleans that needs roofing repair to hire Markelangelo's. Thanks.

I was able to make an appointment within a very few days to replace a 34-year-old set of roof cables which had become faulty and come adrift with the winter ice, and were hanging down, a few feet dangling over the edge of the roof. The craftsman came at the appointed time and completed the work efficiently, tidily and carefully, and within the estimated cost. I was especially impressed by the wiring leading off the roof to the outdoor plug: it was straight across and straight down—very neat and visually appealing. Thank you!

After a huge wind storm and 1/2 of my shingles gone, Markelangelo's team got back to me quickly and sent a team the next morning to patch the roof until further decision could be made. Excellent communication and work, thank you

Markelangelo’s Inc. is a terrific Ottawa area roofer. Starting with the sales rep, Kevin, who patiently and professionally responded to all my concerns and provided a detailed quote, to the installation team that arrived on time, completed the roof within a day, cleaned up after themselves and again, responded to my questions, to Amber in the office handling scheduling and invoicing, it was a very positive experience in this negative time!

I had Kevin provide an estimate for my attic insulation, and he was very prompt in responding to my request and getting the proposal ready quickly.

The installation team, led by Stephen, did an outstanding job. He was polite, professional, and incredibly helpful in answering all my questions. On top of that, he went above and beyond by checking my roof and fixing broken shingles, even though it wasn’t part of the contract. He truly treated the job as if he were working on his own home. Stephen was so great to work with that I plan to request him specifically for my upcoming roofing project.

Thanks for the great work!

Very happy with the service for Markelangelo roofing. We have issues with our roof and knew it needed to be replaced. They came within the same week and completed our roof in a day also installed new baffles. We also had issues with our vents where they found a better solution for them. Workers were very pleasant, and the cleanup was great! never know they were here!

Markelangelo’s was recommended to me by a very good friend who had his roof done by them around 15 years ago. From what I can tell, they haven’t missed a beat.
The pricing was extremely competitive and their guarantee is second to none
The crew was punctual, polite and knowledgeable. Michael was in charge of this very professional crew and made sure everything was done as promised in a timely and tidy manner. They did a great job protecting the property before they started and cleaned up after they were done.
I would not hesitate to recommend this company to anyone in need of a new roof.

Markelangelo's Roofing did a great job in replacing our roof shingles in a very quick and timely matter. When we contacted Markelangelo's we had a response in less than 24 hours and set up an appointment the following day.
Kevin came out took a look at where we had a leak, then looked at the roof and flashing tracing back from the leak. Kevin then proceeded to inspect the attic for any signs of water damage or leaks, and even went up on one of the secondary roofs to check if the boards were stable.
The job was completed in less than two weeks from the time we signed with Markelangelo's Roofing.
We are very pleased with Markelangelo's Roofing and would highly recommend them for any roofing contract.
