Sometimes, replacing a roof will be the most practical, cost-effective and ultimately necessary option over repairing section after section of damaged areas.

At Roy Dennis Roofing, we’ve been installing roofs throughout Greater Vancouver since 1946. With literally hundreds of years of combined experience roofing in our often-unpredictable West Coast climate, we’re happy to work with you to find the best option for your budget, building type and needs.

We install and repair virtually all types of roofs.


Whether it is a residential, commercial or industrial roof that needs to be replaced, our solutions include a wide range of materials, such as:

Sloped or shingle roofing:

  • Laminated asphalt shingles of all designs and profiles.

  • Cedar shingles and shakes

  • Cedar conversions, which involves removing the old cedar shakes and shingles on your roof to substitute it with a roofing material like GAF shingles

  • Composite shingles.


Flat roofing or torch-on roofing:

  • SBS also known as torch-on, an asphalt and rubberized based flat roof solution to replace older tar and gravel roofs

  • Metal roofing, made from metal tiles

  • EPDM rubber, which is a synthetic weather-resistant rubber roofing membrane commonly found in built in gutters and on large warehouse buildings

  • TPO and PVC, which are cost-effective and durable single-ply roofing systems made of thermoplastic membranes ideal for large open areas

  • Hot rubber


For sloped roofing or shingle roofing, we usually recommend

  • GAF shingles, which follow the standard architectural, and designer patterns and for which we are “Master Elite” and “Green” certified installers.

  • CertainTeed, with their full line of architectural and designer shingles, underlayments and accessories.


While for flat roofing or torch-on roofing, we would usually recommend to work with Soprema SBS torch-on for which we are “PAC + S” certified.

We re-roof not only residential but also commercial and strata roofs!


We not only provide residential re-roofing but also commercial re-roofing services for a number of different sectors, including commercial and retail buildings, schools, hospitals and heritage buildings.

When your roof reaches the end of its practical life, and it’s time to replace it, we can provide practical options for your home, business or organization that meet your project schedule and budget.

No matter the size of the re-roofing project, our crews will work with you to complete your new roof in the safest manner possible, and our ultimate goal is to keep disruptions to your ongoing operations to an absolute minimum.

The re-roofing process


Before we recommend a roofing option, we’ll evaluate your entire home and building envelope, taking into account issues such as ventilation, vapour barriers, attic insulation, dew point and roof deck condition. Your new roof may be as simple as installing new shingles or as comprehensive as adding additional layers of insulation or power ventilation systems to ensure your roof accommodates the needs of your home or commercial building.

After agreeing on the roof replacement evaluation, we will proceed to developing a comprehensive safety plan that protects you the owner and our employees. One that meets the most stringent requirements of Work Safe BC.

Once the safety plan has been established we then derive a course of action for completing the work as described in your quote.  We start by protecting your property.  This may be as simple as setting up a tarp or as complex as erecting scaffold and staging.

The actual process of ever individual project is unique and has its own challenges.  Your quotation will explain in a step by step manor the process for your project and the materials that will be used.

Re-roofing is obviously a heavy project and the disruption to the customer can be somewhat significant. We are extremely focused on how the home is left at the end of each workday and special attention is made to leave the property cleaner than when we arrived.

Finally, a magnetic rack is used as the last step to finish each and every project, with thorough debris clean up.

Roof replacement timing


Most re-roofing projects can be completed in a timely manor with multiple crews working every day to keep our customers home dry and safe form the elements.

Our roofs are built to last. Just like us. 100% satisfaction guaranteed!


All of our installed roofs come with our standard 10-year labour guarantee, and our flat roofing carries an additional non-pro-rated 10-year guarantee on material. Because Roy Dennis Roofing is Master Elite and Select Shinglemaster certified, we are able to offer warranties other contractors can’t touch on architectural and designer shingles from both GAF and CertainTeed.

We know what you’re thinking – most roofing contractors go out of business within three to five years, making their warranties as worthless as discarded shingles. But we’ve already been in business for more than 70 years. Roy Dennis Roofing is also a member of the Roofing Contractors Association of British Columbia, an elite group of professional roofers with strict requirements to exceed building code standards and uphold principled, sustainable business practices.

We guarantee that if you choose us to look after your roofing needs, you’ll be 100% satisfied with the products and service we provide. If something’s not right, we’ll make it right. That’s just the way we do things around here. Always have, since 1946.
