Excellent Service

“Great service from this company! They inspected the roof prior to providing an estimate, arrived on time, finished the job when they said they would and were very professional. The workmanship was excellent and Simon was very friendly, helpful and answered all my 101 questions. I would recommend them to everyone! Thanks.”

Professional Roofing Services

“I contacted Simon last year close to winter time when we realized that our roof was ready to be replaced. He suggested to wait till this spring for re-roofing and caulked some areas in roof to get over winter. He gave us a very reasonable quote and good advice. Based on 5 quotes I received this year, i decided to go with Simon quote for roofing and eve’s trough replacement work. Our roofing work was done in the first week of May. The crew worked very professionally. Based on his work, our neighbour also went with Simon for roofing. I am very happy with the work and have no issues recommending him to my friends and family.”

– DP in Markham

Reasonable and Competitive Prices

“Look no further and save yourself time. Simon is the company to call for your roofing needs and he came highly recommended to us. We called five companies and received two call backs. The prices were high and I decided to call Simon based on the referral. Boy was I impressed. He had all his documentation in order, price was reasonable and competitive. He kept me posted on scheduling delays due to the weather and showed up when he said he would. Overall, the roof looks great! We had one spot on the roof that didn't look right and he came back within days to inspect. The issue ended up not being his fault, highly recommend Simon.”

– Andrew in Pickering

Reliable Roofer

“I got Simon’s number through my friend. He highly recommended Simon as a very reliable roofer. He came and gave us an estimate last year close to winter time, and he recommended that we should wait for the spring to do it because the shingles put on for winter time might have problem with sealing to the roof. He gave us a very reasonable price and good advice. We took his advice. He went onto the roof and did some patching work for me just to ensure we will have no problem in the winter. He came back last week and did our entire roofing in one day, his crew works very professionally. They cleaned up all the waste after finishing the work, even the nails on the property were removed with a magnet. I am very happy with their work. I will recommend him to my friends and family.”

– Kelly in Scarborough

Dependable Workmanship

“The owner did a first free check-up for us last Christmas and offered practical advice. This year we chose Guildwood Roofing and it’s been a good decision. Simon was very patient at answering our questions and concerns, and provided us with solutions that are most economical and practical. Prices are in line. Workmanship is efficient. Everything was done on the same day. The company followed up with letters and contacts info and we feel we are well serviced. I will surely recommend Guildwood Roofing to family and friends."

– Celeste in North York

Timely and Effective

“Excellent service arrived on time, started at 8:00 AM and finished at 3:00 PM, great price. I would recommend Guildwood Roofing to my friends. The price was $2500 dollars less the sears. Guildwood Roofing has the same warranty as sears and they could install the roof when I wanted it done.”

– Phil in Scarborough

Very Quick

“Thorough professionals. Price in line, workmanship was outstanding and quick. My next door neighbour who is a builder came over, looked at the job and asked for a card. They've done several jobs for him with the same great results. Highly recommended!”

– Paul from Markham

Customer-Friendly Company

“Our roof started to leak during the worst rainstorm we can remember. Checking the Yellow Pages, I called 3 different local roofing companies looking for help. Not one returned my call. Then I found a small ad for Guildwood Roofing and it said Emergency Repairs. Much to my surprise Simon answered the phone, listened to my problem and said he would be at my door in 30 to 45 minutes. It was Sunday, pouring rain, yet he came as promised. Climbed onto the roof and made several temporary repairs to stop the leaks. Because he was so helpful we asked for a quote to do the whole roof. Simon came inside and showed us his portfolio about his business. His metro license, workers compensation, liability insurance, better business bureau and several certificates from roofing manufacturers, are all up to date. His price was very reasonable and he was contracted to do the reroofing in 2 weeks. One week passed and he called to say he could have his crew in on Sunday morning to do the job. The crew were very courteous, did a fabulous job and cleaned up so well you would not know they had been there. Simon came by on Monday to inspect the work and check if we were satisfied before receiving payment. It doesn't get any better than that. We would highly recommend Guildwood Roofing, Simon and crew to all our friends and neighbours. Thank you Simon.”

– Wayne in Pickering

Highly Recommended

“I received many quotes and Guildwood Roofing was one of the better ones even with better shingles. Simon was the only company that gave me the quote in person and answered all my questions. The roof looks great and I am very happy with the job. Highly recommended.”

– Nick C.  from Whitby

Exceptional Roofing Services

“After a very windy day last fall, I was looking at missing shingles on our roof just as an acquaintance who is a well-established realtor in the neighbourhood was driving by. He stopped to say hello and asked if he could help. I asked about a reputable roofer and he recommended I contact Guildwood Roofing. I called and Simon got back to me the same day and made an appointment to come and inspect the damage the next day. He kept the appointment and patched up the roof within an hour, suggesting the roof may need re-shingling in a year or two. Earlier this spring we decided to get some quotes, from Guildwood Roofing and three other well known (advertised) roofing companies. Simon was first off the mark. Company B showed up promptly a week later produced a proposal on the spot and that was the last I heard from them. Company C missed their appointment and when I called them the next day we arranged for a second try and got my 3rd quote. Company D never bothered calling back to respond to my quote request message so I imagine they had more business than they could handle. Not only was Guildwood Roofing’s quote most reasonable, my experience with Simon was both tangible and positive so it was a no-brainer to contract with him. Most calls with questions were answered very promptly and as the suggested date of the job was approaching I was called a couple of times to firm it up and be provided with last minute pointers. The job itself was carried out by a crew that was clearly well experienced and worked together in complete harmony. The perimeter of our house was left in a pristine condition with all debris (especially nails) removed from both ours and neighbour's properties. The morning after the job was done; Simon went up on the roof to inspect everything and even produced some pictures of areas I could not see from the street level. What Simon Zhao Says, Simon (and his crew) do. I would recommend Guildwood Roofing to anyone without hesitation.”

Roof/ Eavestrough Replacement

“Simon / Guild wood roofing is very professional, good coordination & workmanship, punctual with the time line. Really a great job from his team. I will definitely recommend his company!”

– Vinod in Scarborough

New Roof Installation

“I was referred to Simon by a friend and was extremely happy and grateful that I was. Simon stands out in this industry with his professionalism, quality and level of service. He was happy to provide me multiple options for shingles and was open and transparent about the benefits of each.

After we decided to go with Simon and his company he was extremely quick to schedule us knowing that we had a leak and there was a significant rain storm imminent.

The actual work looks great, took appropriate measures to ensure no property damage and their clean-up was comprehensive.

I would definitely recommend their company to others; it's nice to work with someone that is easy to trust.”

– Rob in Ottawa

Hardworking and Polite

“Very hardworking, professional workmanship. Sent a large enough crew that got the entire job done in one day. Stripped the roof, cleaned the gutters and lawn of debris. Highly recommended.”

– Sue M. in Scarborough
