I would recommend Gauthier Roofing to everyone. This was the second time that I referred them and this job in particular was for my moms home. I can't say enough about this company. The communication from the first point of contact was incredible. My mom was impressed with the workers as they were very professional, left the job site clean and spoke with out using vulgar language as they worked all day. When my mom had questions they took the time to answer any of her concerns.This was a stress free experience for my mom and myself from start to finish. The roof looks amazing and my mom continues to receive compliments.Thank you Ron!

I received a quick response on my request for quoting and I had the estimation in writing within the next two days. The quote described in detail the scope of work and was easy to understand. I added a few details and the updated quote came in promptly. As for the price, it was in line with other estimates. The job was completed on time and the quality was as expected.

We are very satisfied with the work done on our garage roof recently by Gauthier Roofing Company. They started the job early and finished it within the day. I choose this contractor again since they also did an excellent job on our main house roof repair back in 2017 after it was damaged by a wind storm. I highly recommend this company.

We hired Gauthier's to install new eavestrough and downspouts and are extremely happy with the results and the price. Ron provided an estimate within a day or two of contact and answered all questions just as quick. They showed up when they said they would, completed the job when they said they would, and cleaned up like they were never here. That alone in this day and age is worth 5 stars. They provided a quality product and quality workmanship. The staff was friendly and professional. We are very happy with the process start to finish as Ron and his team made it very easy. We highly recommend them and they will definitely get the call when a new roof is needed. 10 stars all day long !!!

I have now had a chance to thoroughly evaluate the new eavestroughs and drainpipes that you installed last fall, and I have to give credit where credit is due. Despite my initial misgivings, the new system is a vast improvement over the previous one, and the covers over the eavestroughs are working very well. All that is needed is an annual cleaning to remove a build-up of maple keys in the corners. Other than that, there has been no overflow, even in the heaviest of downpours that we have been getting recently. The new system is well worth the investment!

In the past Gauthier Roofing and Siding did a terrific job of putting new siding on my home. Last week, they came and put a new roof on my home. Before they came, I received an email of what to expect during this job and when they would arrive. The crew was on time and went straight to work. When they were done, the yard was clean. They even came back to check the yard again. The job is absolutely BEAUTIFUL. I love the new look of my house. They are definitely my "go to" choice.

The Gauthier team are incredible to work with. Knowledgeable, courteous and thorough. Ron follows up on every job to ensure you are happy. When I had roofing problems he explained my home's quirks and how to fix them. He went above and beyond tracking down a part for an out of warranty patio door. Talked me out of doing some work and saved me money. I value and trust him and appreciate his team of workers.

When a new roof is needed, most people want a reliable, punctual, honest, trustworthy, and knowledgeable company that can do a great job. We got all of this, and more, from Gauthier Roofing and Siding. Ron is prompt to answer questions, and provides detailed information about what to expect. Our new roof looks terrific. They showed up when they said they would (important to us!) to provide an estimate, and then showed up as promised in November 2020 to work on the roof. All completed in one day, even though there was at least two layers of old shingles to strip. The crew was polite, considerate and the clean up was perfect. We would highly recommend this company to anyone looking for a roofing/siding company.

Gauthier Roofing & Siding has done work in the past for us so there was no question who we would call to replace our eaves. Do to the covid virus we were unable to get the work done as set out but that didn't stop Ron from e-mailing us almost every week to keep us abreast of the situation. We finally got it done and the father,son team that did the work were great, they did a great job and cleaned up after. We would highly recommend anyone to go with the best company. Bev & Loui Svarc.

I am writing this review as recent customer. I had my roof and eaves replaced three years ago by Gauthier Roofing. Ron was very thorough and attentive. I was well informed, starting from the estimate to the job completion, knowing what to expect at each stage. Ron provided timely calls and/or emails throughout the process, addressing our concerns of weather, timeline and material used. His crew is very professional on the job site, leaving the site tidy and clean during the job. My yard was returned to its original condition upon completion of the job. My roof and eaves look great three years later. I have had no problems and have recommended Ron to many friends and family. I will definitely use Gauthier Roofing again and highly recommend them.

I have conducted business with Gauthier Roofing since I became a homeowner in 1994. Throughout those years and two homes owned, I would only use Gauthier Roofing to make any repairs or replace my roof. Over the years I’ve had three roofs, a skylight installed, siding, caulking and flashing around the windows replaced. It has brought me peace of mind knowing that it was done correctly. Ron is extremely professional and honest. His staff and employees conduct the same work ethic and for that alone Gauthier Roofing is worth every penny for peace or mind that the job is done once and it’s perfect.

Gauthier Roofing was very professional in handling my leaky roof situation. They stripped off the old shingles, cleaned up the mess and repaired the roof where a potential problem could have given me grief in the future. A final inspection was done after the job was complete by the owner Ron himself. I would definitely recommend Gauthier Roofing to anyone.

I have been dealing with Gauthier Roofing and Siding since 1993. The quality of work, and professional service is what keeps me coming back. To date I have had 3 roofs done by Gauthier Roofing and Siding, and you can guarantee that they will be doing the roof at our new home when the time comes.
Gauthier Roofing and Siding is without a doubt a 5 Star company! Professional, honest, hardworking, friendly are just a few of the words that come to mind when I think about the outstanding job they did with our new roof.. We never hesitate to recommend them whenever we can!

There are many, many roofing contractors you can call to quote and do the roofing job on your home. For me I don't bother getting second or third quotes. I have been more than happy with the work done both at my home and my mother in-law's home by Gauthier Roofing & Siding. Ron came out the same afternoon I called to look at my roof and give me his opinion. The work was done as promised and professionally. When the time comes to redo my roof rest assured it will be Gauthier Roofing I will be contacting.

Gauthier Roofing provided me excellent customer service and worked within my schedule to install a new roof on my home. The installers and everyone I dealt with in the Gauthier roofing company treated me fairly and kindly. This is an awesome choice company if you need a new roof.

We priced out having our eavestroughs replaced a couple of years ago and decided on Gauthier Roofing and Siding. Were we ever happy with our choice!Quality products installed by quality workers left us so satisfied that when it came time for our roof to be replaced last summer, they were the first people we contacted.The crew that came out to do the roof were awesome, worked themselves to the bone and cleaned up the mess all through and after the job was complete.It all starts at the top as Ron will stay in email contact with you before, during, and after the job is done.I recommend them to anyone who is asking.

The men who came to replace our eaves, fachia and soffits were very professional and friendly. They answered all our questions and cleaned up after the job. We would not have known they had even been there except for the fact that the house looked great! Would definitely hire them again.

I woke up one morning to find a pool of water in my Hallway. I quickly got a bucket to catch the water wondering which way to turn. I thought of Ron (Gauthier) within an hour of 'phoning he was at my home with workmen to patch the roof temporarily. Albeit being extremely busy, the crew were at my home within a few days to replace the roof. Now,that's what I call SERVICEThank you for a beautiful new roof and I appreciated the way the workmen cleaned upafterwardsSincerelyLisa Baker

Gauthier Roofing and Siding FAQ

How do I choose a good contractor?

First and foremost, do your research. Ask friends, family and neighbours for the names of contractors they have used and would recommend. Search online and check the contractor’s ratings and reviews, including the BBB. Find out what year the company was established. Thirty years of experience doesn’t necessarily mean 30 years of operation. See if they have been successful enough to own an actual business establishment, as compared to simply working from home, which shows sound business policies and typically a greater chance of being around in the future. Make sure the contractor carries public liability, property damage and WSIB insurance. Get detailed written estimates, nothing vague and don’t rely on a handshake. Be careful with deposits, ideally avoiding them. Lastly, don’t rush your selection. You are going to live with the work for years and maybe even decades, so taking the time to select the right contractor will save a lot of frustration, time and possibly added expense later.

Why is the pricing so different between my estimates?

For the most part, this oftentimes comes down to the details of what is actually being quoted, commonly known as the scope of work. There are numerous ways that all home improvement projects can be done, along with a variety of materials that can be used. If a roof, for example, is done without complete underlayment and entry level materials, it’s going to cost less than a complete integrated roof system with better quality materials. A contractor without proper insurance coverage can also work for less than one who has complete coverage. It’s important to look at what each contractor is offering in terms of the best protection for you, as well as the actual scope of work. It’s easy to see some similar words or phrases on estimates and assume they are the same, as home improvements aren’t every day purchases and can be confusing. However, it’s important to compare closely and ask lots of questions to clear up any confusion. Typically, home improvements are much like everything else, in that you get what you pay for.

I found a contractor that can start right away, should I be happy or concerned?

Although this may originally seem great, if it’s the busy season it typically should raise a red flag. Good contractors are going to be busy during the busy season. Finding a contractor that no one else wants isn’t a good thing. It’s easy to lose sight of this in the excitement of getting your project done, but it’s best not to rush into anything. Even if you have a leaking roof, for example, a quick temporary repair can be done (oftentimes free upon authorization of a complete roof replacement), so that the immediate concern is addressed quickly, alleviating the pressure to act fast and make the wrong decision.

Why are asphalt shingle roof warranties so confusing?

Typically, the main thing to keep in mind is that the manufacturer warrants the product and the contractor warrants their workmanship. The manufacturer warrants the shingle and any covered accessories against manufacturing defects. Exactly what is covered and how, will be outlined in the manufacturer’s warranty. Coverage does vary between manufacturers, so it is important to read the warranties. From these basic warranties, manufacturer’s also offer enhanced warranty coverage when roofs are installed by their certified installers and a specified scope of work is followed. The actual workmanship is warranted by the roofing contractor, but there are certain enhanced warranty coverages available where the manufacturer also warrants the workmanship. To add a little more confusion, the manufacturers typically also note the labour coverage in their warranties, this means the labour coverage involved to replace the roof in the event of a manufacturing defect. This labour is not the same as the workmanship warranty.

I plan to have my vinyl siding replaced; can I have insulation added at the same time?

Yes, and it’s typically recommended. A wallboard insulation can be installed once the old siding is removed. It’s available in a variety of styles, thicknesses and R values. Many come with a housewrap and the joints get taped. Energy efficiency is improved along with air infiltration and noise transmission. By insulating over the exterior wall in this way, it prevents thermal bridging at the wall studs, adding to the energy efficiency. In addition, the insulation provides a better surface for the installation of the new siding.

How do I know when it’s time to replace my windows?

Windows are typically replaced when they become difficult to operate or lock, when a draft can be felt when closed, or when there is moisture present between the panes of glass (called a seal failure). Sometimes they just look old and worn over time. New windows are going to be more energy efficient, look better and typically block more outside noise. There is also oftentimes better fade protection where sun enters the windows hitting furniture, flooring, etc. Energy efficient replacement windows come in an array of styles, sizes, shapes and colours.

Rainstorms seem to be getting more intense and my eavestrough can’t seem to keep up, what can be done?

One option is going to a larger size eavestrough, but what is oftentimes recommended when replacing a complete residential eavestrough system is upgrading to larger downpipes. This way the eavestrough doesn’t look too bulky and the speed in which the eavestrough can drain, is more important than how much water the eavestrough can hold. Typically, the downpipes we use are 50% larger than the existing ones. We also use heavy-duty, screw-type aluminum hangers. These hangers are concealed, won’t snap or corrode and are secured with special rubber-washer bolt-head screws. We can even install covers (aka gutter guards) on your new or existing eavestroughing, so you’ll never have to clean them again.

EAVESTROUGHING

We've Maintianed a  Continuous A+ Rating with the BBB Since Becoming a Member Over 45 Years Ago

We were looking to redo the entire exterior of our home. I had seen that this company was in business for many years. I received quotes from three companies. What sold me to go with Ron Gauthier was the quality of the materials he would use on the house and the explanation of how it would be done. He had great knowledge from years of experience. When the job was done the house looked amazing. The quality, the workmanship and the care of my property was outstanding. Ron's company has been back for two more exterior projects, and the same excellent results.

A wonderful experience from start to finish. We had siding, soffits and eavestroughing and recladding of all our windows done. Everything looks amazing, the workmanship is exceptional, our home looks new again. We were informed at every stage what would be happening, the company managed to fit us in earlier than planned, which was wonderful. Very professional from receptionist to installers. The staff did really treat our home as if it were theirs. We have had many, many, really positive comments. We are already recommending to friends and family. Job well done.
