Flat Roofing in lethbridge

Riddler’s Roofing is a division of Delrei Roofing Exteriors & Restoration. We specialize in handling insurance claims and new construction for commercial and residential properties, including torch-on roofing, within Lethbridge and the surrounding communities. We offer a 5-year workmanship warranty on all roof installations and provide free estimates. We will visit your location, assess the situation and provide solutions for any recommended repairs or maintenance. We can often identify problem areas before any leakage occurs.

Our team is fully licensed with Certified Journeyman and Certified Torch Specialists. We maintain the proper documentation which allows us to preform our work with torch products and built-up roofing systems. We are also WBC registered and insured for additional peace of mind.

Reasons to Upgrade from Tar and Gravel to SBS Torch On Roofing

  • Less maintenance (no re-graveling bare patches)
  • Less expensive to maintain 
  • Less expensive to replace
  • Depending on the integrity of the roof, SBS roofs can often be primed, avoiding complete replacement, saving you money 
  • Less mess
  • No gravel plugged drains
  • Newer technology
  • Tar and gravel roofs are quickly becoming a thing of the past; soon there will be no one left with the experience to repair them
  • People are wary of tar and gravel roofs (a bucket of gravel and some tar can easily hide problem areas) 
  • A new SBS roof can greatly increase resale value

Questions to Ask a Potential Contractor

Do you have WCB Coverage?
Do you have proper torch and hot tar insurance?
Do you have liability insurance?

Mistakes can happen. Make sure you know who is liable if they do. Without the proper coverages, it could be you. Riddler’s Roofing believes in keeping coverages up-to-date to protect our clients.

We install, repair, and maintain a variety of flat roofing systems including:

Built-up roofing (BUR) installation and repairs
Single ply membrane installation and repairs
Modified bitumen SBS 2-ply and 3-ply installation and repairs
Tar and gravel repairs and maintenance
