Not sure how everyone says they respond promptly. Hubby requested for quote on steel roof in June, never heard from anyone.

Hi Clare, I’m really sorry, but we are not installing metal roofs this season due to the lack of demand. This has been communicated to anyone who has contacted us for a metal roofing quote this season. I am sorry that this was your experience. Sara

I called Warner Roofing to get a quote on shingles I needed to replace on my home. I spoke to Andrew on the phone to schedule an appointment for a quote, no one ever showed up. I decided to give them another chance as we are in the middle of Covid19 and it could have been related nothing - Sara even emailed to confirm that someone would drop by. Nothing. While I understand the company might be backlogged or have too many roofs to change - just say so. Other roofing companies told me that they were backlogged. Long story short if you unable to give a quote or do the job please say so. Anyways we got our roof done!

Chose Warner Roofing to roof my girlfriend's house. Fantastic work and clean up job. All the workers were friendly, answered questions and were totally professional. I also must commend the office staff. They were quick to reply by phone and were courteous and professional. When my roof needs replacement it will be Warner Roofing who does it as well.

Everyone was great to work with from the first phone call to the repair technician, Clay, who did an excellent job and took plenty of pictures to show us both the problem before and then after the repairs. We would recommend them to friends and neighbours and would use them again if needed in the future.

Homeowner’s worst nightmare during winter is a leaky roof. As snow builds up on the roof, many contractors refuse to come out to perform repair or have weeks of backlog banking on better weather gonna come soon. When I contacted Warner …

Very professional. Competitive pricing, great warranty. Always in communication, keeping me informed of progress, problems etc.. Picture of work in progress is a nice touch. They upgraded and repaired the eaves troughs at Trinity Anglican church in Aurora. Fast, clean. Offered alternatives to select best value. We would recommend them to anyone in the area

Warner roofing came promptly after I called them about shingles that blew off my roof. I spoke to Amanda and arranged the repair. Clay and Robyn arrived. They took photos, walked me through the concerns that they would address. they replaced the missing shingles and checked the rest of the roof. Very professional! Warner Roofing are a pleasure to deal with. I highly recommend this company for all your roofing needs.

I hired Warner Roofing Inc. to replace a soffit panel and to secure the adjoing loose pieces. The other portion of the job was to caulk a right angle eave joint. The workmen completed the job as scheduled. I found that Warner Roofing Inc. was professional and communicated effectively. I am satisfied with their service and would use this company again. Further, I would highly recommend this company to others for their roofing repair needs.

Outstanding service and repair. I sourced Warner online after storm damage. They were prompt with scheduling and the repair to our roof. They also advised us that we required a minor fix to an aging vent. They supplied images before and after which was great. Highly recommended!

I called Warner roofing following the discovery of some loose shingles and water damage after the weekend storm. They were able to send somebody out the next day to address the issue. They were very quick, professional, easy to deal with and the repair looks great. They even sent me photos of the areas needing attention for my information. Price was competitive and I would definitely call them again.

We called Warner to come look at our roof after a wind storm due to some damage. We expected to have to replace the room but a couple repairs and we're good. Honest, prompt, and professional. We did get a quote and will be doing the room next year with Warner.
