Homeowners consistently report fast response times, fair quotes that often undercut competitors, and reliable completion. Serg and named crew members (Andriy, Sergiy, Andrey) earn praise for catching problems others missed, protecting property during work, and leaving sites spotless-though one reviewer noted questionable debris handling.
The business handles flat roof repairs, shingled installations, metal roofing, gutters, siding, and emergency snow removal across the GTA. First-time homeowners and those burned by other contractors highlight their honest assessments and stress-free communication. Wind and storm damage jobs receive same-day response.
Ali's team delivers thorough, full-scope home work-from bathrooms to whole-house renovations-on schedule and within budget. Reviews consistently highlight professional tradecraft, clear communication, and a willingness to solve problems as they arise.
Gitano's initial installations earn consistent praise for quality and clean work, with some roofs lasting 7-8 years without issue. Post-installation communication collapses, however: warranty claims go unanswered for weeks or months, leak repairs are repeatedly promised then delayed, and the owner (Lewis) contradicts himself on coverage and timelines. Customers report being passed between staff members with no resolution, while damage from unaddressed leaks accumulates. The pattern suggests the business excels during the sale but fails to back its work afterward. A 2017 installation still holds strong, yet multiple roofs from 2018-2020 are already leaking and the company refuses to engage despite warranty terms. Reviewers describe the experience as stressful and the business as lacking accountability.
Across 15 reviews all five-star, Gentech earns consistent praise for fast, professional work and standout customer service. Customers name staff members-Christine, Roger, Sue, Tina-as responsive and skilled. One reviewer credits Roger with diagnosing a difficult leak that had persisted elsewhere; others highlight efficient completion and clear communication. The office team handles scheduling and updates smoothly, making the whole process feel organized and stress-free.
