Roofing and Exterior Services in Ottawa

Big City Roofing — Professional Roofing Services in Ottawa

Big City Roofing provides roofing services in Ottawa for homeowners, businesses and multi-residential properties. We focus on roofing-first exterior projects, from new asphalt and metal roofing systems to diagnostics, repairs, water management and winter maintenance across Ottawa and the Ottawa Valley.

Natural Resources Canada explains that ice dams can cause meltwater to back up beneath shingles and lead to leaks, while the National Research Council of Canada notes that snow load depends on the weight of snow, not simply its depth.

That is why at Big City Roofing, our approach starts with the building, its condition and its exposure — not simply with a roofing product. Start with a professional assessment to determine the right roofing solution for your property.

Residential Roofing Services

Our residential roofing solutions are designed around the specific requirements of each property. Whether you are replacing an aging roof, upgrading to metal or addressing a leak, we help identify the appropriate system and scope of work.

Asphalt Roofing

We install asphalt roofing systems using industry-leading shingles from GAF, BP and Owens Corning. The right shingle depends on the roof design, exposure, appearance and expected service life.

A proper installation also requires attention to the roof deck, flashing, water protection and ventilation — not just the visible shingles.

Metal Roofing

For homeowners seeking long-term durability and a distinctive appearance, we offer premium metal roofing systems, including standing seam and Hestia metal tiles.

Our metal systems use European-made steel manufactured locally in Canada, combining high-quality materials with local production and installation expertise.

Siding & Architectural Finishing: Exterior Solutions That Complete the Building Envelope

A roofing system does not work in isolation. Its performance is closely connected to the components that manage water, air and weather around the building.

Big City Roofing also provides siding and architectural finishing services that help protect the building envelope while giving the property a clean, finished appearance.

Premium Siding Installation

Maintenance-free steel and vinyl siding options from Gentek and Buchner, designed for durability, low maintenance and lasting curb appeal.

Architectural Finishing

Professional installation of soffit, fascia and custom capping to help protect exterior transitions from water intrusion and create a clean, complete finish.

Additional exterior services include:

• house wrap;
• flashing and capping;
• seamless eavestroughs and downspouts.

This coordinated approach allows homeowners to address multiple exterior needs within one project, with consistent workmanship and a single point of contact.

Specialized Projects: Commercial Roofing Solutions

Our commercial roofing services are intended for businesses, multi-residential properties and other larger buildings where durability, drainage and operational continuity matter.

An industrial roofing company must consider more than the membrane itself:

• roof configuration;
• drainage;
• penetrations;
• equipment;
• maintenance access.

It all affects long-term performance.

For commercial properties, our scope is developed around the building and its requirements rather than a one-size-fits-all product.

Ottawa Emergency Roofing Services, Water & Winter Management

Roof problems become more urgent when water is actively entering the building or snow and ice create excessive loading or drainage problems.

Emergency roofing services in Ottawa can help identify the source of an active leak and determine the appropriate response. Big City Roofing offers priority scheduling for active leaks, subject to weather and crew availability.

Winter maintenance can help prevent avoidable damage. The Government of Canada recommends professional roof snow removal when needed and warns that heavy snow and ice can contribute to structural damage and leaks.

Our winter and Ottawa emergency roofing services include:

• roof snow removal;
• ice and snow buildup assessment;
• leak diagnostics;
• targeted roof repairs;
• drainage and eavestrough solutions.

Do not attempt to access a snow-covered roof yourself. The National Research Council of Canada recommends using a qualified and insured professional for roof snow removal.

Roof Repairs & Diagnostics

A leak is not always caused by the main roofing surface. Water can enter around flashing, valleys, penetrations, vents or drainage components.

Our diagnostic approach focuses on identifying the source of the problem before recommending a repair. This can help prevent repeated patching and unnecessary replacement.
