In roof replacement, there’s no substitute for experience.

Since 1988, we’ve replaced more than 100,000,000 square feet of roofing across Canada. No matter what system or who installed it, eventually every roof needs to be replaced. Proper maintenance is vitally important to a roof’s lifespan, but the impacts of time and severe weather will take a toll on any roof.

The challenge of roof replacement involves dealing with many factors that don’t come into play when installing on new construction. Nedlaw Roofs understands this firsthand. We have extensive experience with owner and tenant-occupied projects that involve working around existing construction and landscaping with minimal disruption, yet maintaining the highest quality results.

We are authorized applicators of:

  • Built-Up
  • Modified Bitumen
  • EPDM
  • TPO
  • PVC
  • Tremco
  • Garland
  • And other various roofing systems

Service and Repair
For EMERGENCY SERVICE call 519-648-2218


Our RoofCheck Service can greatly extend the lifespan of your roof and allow you to correct minor problems before they become costly leaks or failure. In addition, regular roof maintenance will help maintain the resale value of your building.

Protect your investment!
With our bi-annual RoofCheck you can:

  • Achieve up to double your roof lifespan
  • Meet manufacturer warranty requirements
  • Avoid premature roof replacement
  • Identify leaks and repairs early
  • Prevent business interruption due to roof failure

How RoofCheck works:

  • Twice a year, a qualified Nedlaw technician will visit your roof
  • The technician will provide a roof-report detailing maintenance and repairs required, to extend your roof’s life span, noting: roof blisters, open seams, debris, debris clogging and restricting drains, caulking required on penetrations and flashings, redundant roof equipment, future leak sources, roofing membrane assessment, expected life span of roof, and any preventative maintenance required.
  • For any leak or emergency repair we do, a Nedlaw RoofCheck technician will automatically visit the site within 24 hours and provide a follow up RoofCheck inspection. Our findings will be detailed in a roof report for you, advising of any maintenance or repairs required to extend your roof’s lifespan.

Snow Removal

Snow Removal

Heavy snow build up poses serious threats to your roof and building integrity. Our service professionals are trained for working at heights, have the correct equipment and will ensure that snow and ice are removed properly and professionally.

Common Issues with Snow Accumulation:

  • Creates water ponding
  • Leads to clogged drains
  • Threatens safety of doorways and walkways
  • Blocks access for rooftop work
  • Negatively impacts mechanical equipment and venting

  • Foul odours

Much more than a vertical plant wall, a Nedlaw Living Wall Biofilter is in a class of its own. Most green walls are designed for simplicity and aesthetics; in contrast, a Nedlaw biofilter is a working machine. Using Nature’s own science, our amazing biofilters remove pollutants from indoor air and return clean air to the building. As a significant fresh air source, our living wall biofilters save energy by reducing the amount of outside air that needs to be heated or cooled.
