Jaime's crew earns consistent praise for speed, clarity, and follow-through on roofing projects across downtown Toronto and the GTA. Most work is resolved in a day, from ice dam fixes to full replacements, with owner communication starting within seconds of a quote request. One reviewer had to finish a job themselves due to incomplete work, though this is isolated among 50 reviews. The team handles exterior work beyond roofing: aluminum, eavestroughs, gutters, siding, brick, and waterproofing. Igor and other crew members are named for their professional site work and photo documentation for insurance claims. Pricing is consistently described as fair, and repeat customers are common.

All 15 reviews are five-star. Customers consistently report the team diagnosing hidden problems (rotted decking, flashing issues) rather than quick patches, completing work even in harsh winter conditions, and honouring warranty calls. Oleg, Dennis, and their crew have built trust across flat roof teardowns, leaks, and complex row-house jobs over five years.

Tip Top Trough delivers consistent, on-time service across eavestrough cleaning, repair, and replacement work. Reviewers single out named crew members (Pablo, Jonathan, Roberto, Ever, Ray, Iram) for professionalism and thoroughness, praise the company's willingness to tackle difficult access and avoid unnecessary upsells, and report that quotes arrive quickly and projects finish cleanly. Long-term customers report the business has handled their homes for over a decade with no drop-off in quality. Heat cable installation, gutter guard fitting, and downspout work all draw the same pattern: timely arrival, clear communication mid-project, meticulous cleanup, and a crew walkthrough at the end. Pricing is described as fair and reasonably competitive.
