Very happy with their friendly service." > Source: Anonymous (5.0, via HomeStars) > "We discovered Guildwood Roofing through 2 neighbours on our street who had their roofs done by them. We hired Guildwood Roofing to replace our roof as well. We are very happy with the results! They did an excellent job. My husband went up on the roof himself to check the finished product and he was impressed with their work. The roof looks fantastic and the work was finished in one day as there were a few workers who worked on it together. Simon is also very nice and the colour that he recommended was spot on. They also took the time to clean up all the debris all around the house. We highly recommend Guildwood Roofing." > Source: Anonymous (5.0, via HomeStars) ## Trades Roofer, Guttering specialist ## See their work _Portfolio and gallery links this business publishes.

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) 564-7388 - Website: https://www.guildwoodroofing.com --- Source: MyTrustedTraders, https://ca.mytrustedtraders.com/traders/guildwood-roofing Real public evidence only: every figure traces to its named source.
