We’re rated A+ by the Better Business Bureau, hold the Top Choice Award 2008–2015, and are the only Ottawa roofer to receive the BBB Torch Award — plus several BBB Honour Roll listings. Every crew member is trained in Working at Heights, fall protection, WHMIS, propane safety and first aid.

Winter desk
Ice dams don’t wait for spring.
Heavy snow, freeze–thaw cycles, icicles at the eaves — Ottawa winters punish roofs. We clear snow and ice safely from rooftops, then fix the cause: ventilation, insulation and heat tracing that stop dams forming in the first place.
Emergency winter callouts run through the same line as everything else. One number, answered by roofers.

Ledger notes
Asked often
Water stains on ceilings, missing or curled shingles, a sagging roofline, mould or algae growth, and sudden spikes in energy bills. Any one of these deserves a professional look — small issues become expensive fast.
Prevention is cheaper than repair. Inspections catch small leaks, flashing problems and missing shingles early, extend roof life, and keep your warranty valid.
Liability insurance and WSIB coverage, BBB accreditation, open communication, and a written contract with the total estimated cost. Without insurance, you carry the risk.
Yes. Countless commercial projects in 125+ years, plus flat-roof membranes and maintenance — and ice & snow removal with long-term solutions against moisture damage.
