• Staff member Arsen named repeatedly for professionalism
• Fast callbacks on calls and messages

Watch out: One reviewer noted the inspection fee only gets credited toward the final repair cost, so ask upfront how that works.

★★★★★4.5 (344 reviews)score 82/100

Avenue Road Roofing carries by far the most reviews on this list, 344 in total, with named staff like Doug, Fergus, and Kas recurring often for attentiveness on everything from same-day flashing repairs to full replacements. That scale comes with a 4.5 rating rather than a perfect one, reflecting a small number of unresolved disputes alongside the majority of positive experiences.

• Same-day emergency response for urgent leaks
• Large, established team with named staff clients recognize
• Transparent scope and cost discussed before work begins
• Photo documentation and cleanup on each visit

Watch out: One detailed complaint describes a broken skylight seal during repair work and a refusal to warranty the fix, so confirm warranty terms before signing off.

Global One Roofing scores well on a 4.9 rating across 48 reviews, with Peter's team known for showing up on time and, notably, coming back to fix post-handover issues at no extra charge. That kind of follow-through is uncommon enough that repeat clients mention it directly.

• Fixes issues after handover at no extra cost
• Thorough cleanup once work is finished
• Punctual, detail-oriented crew

Bosani is GAF and VELUX certified, with a 4.8 rating across 88 reviews and a habit of getting on the roof for hands-on quotes rather than estimating from the ground.

• GAF and VELUX certified installer
• Gets on the roof for hands-on, accurate quotes
• Fair and transparent pricing
• Attentive to cleanup and installation detail

Watch out: A few reviews cite poor phone communication and one pricing dispute, so get scope and cost confirmed in writing.

Sunshine Roofing has a perfect 5.0 rating on the reviews it has received so far, but with only three on record there isn't yet enough volume to draw firm conclusions about consistency. It's worth a look for anyone open to a smaller outfit, with the understanding that the track record is still thin.

• Perfect 5-star rating on all reviews received so far
• Recent reviews, not an old or stale record

Watch out: Only three reviews are on file, so there isn't enough data yet for a confident read on consistency.

Cherry and Clark carries GAF Master Elite certification, with estimator Don Amero personally handling consultations and crews known for finishing ahead of the quoted window. The 4.4 rating across 19 reviews reflects mostly solid recent work, with a couple of older missteps on scheduling.

• GAF Master Elite certified shingle installer
• Estimator Don Amero handles consultations personally
• Crew often finishes ahead of the quoted timeframe
