Roofing contractors in Scarborough: ranked picks
Scarborough homeowners deal with everything from flat-roofed additions and garages to steep-pitched bungalows shaded by mature trees, and the roofers on this list handle repairs, full replacements, eavestroughs, and chimney work across that range. We ranked them using our methodology, which weighs rating, review volume, recency, and sentiment rather than just a star average. Most of these crews cover the whole GTA, so the same names show up in Scarborough as in North York or Etobicoke.
A lot of the work here comes down to two things: aging eavestroughs and flat roofs on additions, garages, and low-rise buildings. Reviewers across these listings specifically call out ice dam removal with heating cables, gutter rerouting, and flashing work, jobs that come up often in a city where tree cover and older housing stock put extra strain on drainage each winter. Chimney repair and flat-roof replacement also come up repeatedly, so it's worth asking any contractor here whether that's their strong suit before booking.
