What do recent reviews say?

Ken, John, Bruce, and Brad earn consistent praise for professionalism and workmanship on complex roofs and repairs, with lifetime warranties honored promptly and sites cleaned daily. However, two recent reviews flag serious gaps: one customer reached out over a dozen times with no return calls, and another faced a no-show appointment. A Quebec buyer also reported the manufacturer refusing warranty coverage after a distributor bankruptcy, claiming no credible defect evidence and closing the file abruptly. Office responsiveness appears inconsistent; when it works, follow-up support is exceptional.

Praised for
  • skilled technicians by name
  • lifetime warranty honored
  • clean-up after job
  • responsive to follow-up issues
  • professional crews handle complex roofs
Watch-outs
  • no-show without rescheduling
  • poor communication and unreturned calls
  • warranty disputes in Quebec
  • inconsistent office responsiveness

Best for: Homeowners with steep, complex roofs who value named technician accountability and on-site warranty support.
Think twice if: Call ahead and confirm the appointment; one recent customer reported a no-show with no follow-up rescheduling. Quebec buyers should ask how warranty coverage is handled if the local installer ceases operation.

What are they good at?

  • Named technicians deliver complex roof work
  • Lifetime transferable warranties honored on repairs
  • Clean-up daily during installation
  • Quick response on warranty claims

Worth knowing

  • Technicians Ken Moore, John (Sr. and Jr.), CJ, Bruce Mehuys, Brad, and Maurice named in positive reviews
  • Office staff Cheri credited for problem resolution
  • Lifetime warranty is transferable and honored on repairs within 24-48 hours
  • Sites cleaned and organized daily during multi-day jobs
  • Weather delays do not trigger additional charges
  • Specializes in complex roofs with dormers, steep angles, and skylights

FAQ

Is the warranty transferable if I sell my home?
Yes. Multiple reviews mention the warranty is transferable to the next owner, and Interlock honors warranty claims on second homes as well.
Do you charge extra if weather delays the installation?
No. One review notes that despite severe inclement weather extending the job to a second day, no additional fees were charged beyond the original quote.
Can you handle a steeply pitched roof with dormers?
Yes. Several customers report Interlock accepted complex jobs with multiple dormers, steep angles, and peaks that other roofers refused. Crews completed these without charge delays and with daily cleanup.

Recent five-star reviews praise professional crews, clear communication, and thorough cleanup on roofing and attic work. However, older one-star accounts allege aggressive upselling during flat roof assessments, misidentification of existing flashing, and inconsistent technician knowledge. The spread reflects a business with strong execution in some projects but credibility gaps in diagnostics and transparency.

Ivan and his team consistently arrive on time and deliver gutter, downspout, and soffit work that leaves yards and basements protected. He takes the time to assess each site properly, explains options without pressure, and charges fairly for materials and labour. He and his crew (Victor mentioned) clean up after themselves and often spot and fix problems the homeowner wasn't expecting. One reviewer found the invoice format misleading on add-on costs, though the work itself remained solid. Specialties include seamless gutter installation, downspout repair and rerouting to prevent water damage, gutter guards, and soffit-fascia work. The business operates across the Greater Toronto Area under Ontario aluminum licensing, holds full insurance, and has been established since 1998. Emergency calls get same-day response. Most jobs finish in a day or half-day.
