They also cleaned my gutters and installed a mesh over it to prevent tree leaves from clogging it up. Their service is very good and their pricing is very competitive.

That is the classic roofing scam. - Get a written quote that itemizes access (scaffolding or a tower), the exact materials, and the workmanship guarantee, not a vague day rate. - Be wary of demands for a large cash deposit; agree staged payments against work you can actually see completed. - Trade licensing in Canada is set by each province or territory. Electrical, gas and plumbing are licensed trades almost everywhere (for example ESA for electrical and TSSA for gas in Ontario), so check your provincial regulator that the contractor is certified for the work before you hire. - A construction lien is a real risk: in every province an unpaid subcontractor or supplier can register a lien against your home even if you already paid the main contractor. Hold back the statutory amount (commonly around 10%) and get signed lien waivers as you pay. ## Contact - Phone: (416) 848-5888 - Website: https://www.gammaroofing.com --- Source: MyTrustedTraders, https://ca.mytrustedtraders.com/traders/gamma-roofing-inc Real public evidence only: every figure traces to its named source.
