Patrick and his team at Professional Roofers were wonderful from start to finish. They did a great job of repairing our roof (a part was sagging), replacing the shingles and insulating the inside of our sloped roof.They were extremely clean and efficient and communication was great. We really enjoyed working with them and highly recommend Professional Roofers for your next roofing job!

I have used Professional Roofers in the past and continue to be pleased with their professionalism, responsiveness and pricing. We purchased an old house that needed some roof work. Professional Roofers team (Patrick, Carlos, and Fernando) took us through the process and made sure that we understood each step. Professional Roofers also checked in to ensure that we were pleased with the work. Definitely get Professional Roofers to work on all your roofing needs!

I hired Professional Roofers to install a roof on our first home a first years back. Now, at our new house, I knew to call on Professional Roofers to do additional work. Patrick Arraya and his team were professional, knowledgeable, and responsive. This time, they installed new shingles on our garage, and gutters and eaves on our house. As always, I am overjoyed with their work. Already my neighbors' are asking for their information!

Professional Roofers replaced my house’s roof last week. They did an excellent job and we were very satisfied with the work. Earlier, Adam from Professional Roofers came in and explained all details regarding the product, installation methods and warranties. Once I placed the order, I got a schedule. They came on time and finished in less than 2 days. They left the place clean of any debris from my old run down shingles that were already shedding lot of disintegrated shingle pieces. They used tarps all around the house. First day, I noticed that they had ensured that the roof deck was not left unprotected as there was an overnight rain forecast. They did the work in sections. All their workers used fall protection while on the roof, which shows their commitment to safety and human value. If you want quality and professional commitment, I would highly recommend Professional Roofers.

Diego of Professional Roofers did a great job for my place. His team dropped by to put a shield on the ailing roof prior to the rain storm a month prior to installation. Their prices are reasonable and competitive!

Terry Reid

Professional Roofers replaced our shingles 9yrs ago at a far better price that another company quoted. When a storm damaged the roof, it was repaired the next day at no cost. Even later they did another repair, again at no cost. Their service and commitment have been exceptional. We are happy to recommend to family and neighbours.

Came by to fix shingles on roofing they installed 9 years ago with no charge. Mentioned wind damage to our fencing. Told me they have a fencing team. Quoted several thousand less than quote I had. Restored fence to swimming pool building code standards with many new posts and even made a new gate in one day. Friendly personal customer service family business.

When our roof began leaking this past winter we didn't think much of it until the ceiling completely caved in. We had looked at repairing the roof in the past but everywhere we called completely ghosted us or left us uneasy.When we called professional roofers in a panic we were greeted by Fernando who was a godsend. He came in the middle of winter, got up on the roof and was able to do a quick fix to keep us dry and warm until it was warm enough to do the full repair.He talked us through all of our options without ever trying to "upsell" us and made us feel comfortable and secure.You may be asking, why are you writing your review 5 months later if everything was so great?! Well I wanted to make sure the roof was as amazing as the service and it absolutely was.The roof install was quick and clean and the roofers were even cautious of the baby bird nest we had in our yard. Fernando came throughout the week to check that things were running smoothly and everything was perfect.After 5 months we are still amazed at how lucky we got to find such an incredible company and will be calling to upgrade our insulation before the cool winter approaches.Thank you Fernando and your entire team for making us feel like family!

I contacted Patrick from Professional Roofers to obtain a quote for eavestroughs and downspouts. Patrick was both courteous and professional, providing us with a fair quote. The team from Professional Roofers arrived on the scheduled date and promptly completed the work. Afterward, both Patrick and I quality-checked the work to ensure our satisfaction. No debris was left behind, and the old eavestroughs and downspouts were removed from the property. Working with Patrick made the process seamless, and it was a real joy. I would highly recommend Patrick and the team at Professional Roofers to anyone in need of roofing services. Their professionalism, punctuality, and attention to detail are truly commendable. Thank you, Patrick, for making our experience a positive one!

We were extremely impressed with the professionalism and craftsmanship of Professional Roofers when they replaced our roof shingles a few years back. As a result, we reached out to Patrick to replace our eavestroughs and downspouts. Patrick promptly inspected the property and provided a detailed quote. The team from Professional Roofers arrived as scheduled, and Patrick took the time to check if we had any changes in mind regarding the placement of the downspouts. Once the work was finished, Patrick reviewed everything to ensure we were satisfied. The upgraded 4x3 downspouts look outstanding, and we are genuinely pleased with the new eavestroughs. The entire process was highly professional and satisfying, and collaborating with Patrick was a pleasure.We wholeheartedly recommend Patrick and the Professional Roofers team for any roofing or eavestrough needs. Their commitment to quality and customer satisfaction is evident in their work. Thank you, Patrick, for making this experience seamless and top-notch!

Called this company for a small leak in my roof. They were communicative on scheduling an estimate and were able to come out and provide one within a couple of days.The price quoted was fair and they provided pictures to explain what was wrong.Within a few days I had roofers at my house making repairs which they finished within a few hours.Will update again when it rains on if the leak persists.

I was impressed with the Professional Roofers team right from the start. They showed up bright and early and were friendly and polite. They were happy to answer all of my questions and did a great job especially on the clean up. The boss performed a final inspection of the roof before they left. And the price was good. I would definitely use Professional Roofers again. Jim.

I had no idea where to start with a roofing company-I mentioned to my accountant one day that I needed a roof- he said he did his a few years back and told me about Professional Roofers.Well, I’m glad he mentioned them!From my first call to them they were responsive. The sales rep explained everything and followed up after the sale to make sure everything was ok-he continued to be responsive and cared that I was happy.The installers were prompt, detail oriented and experienced.The site manager made sure to ask about satisfaction and updated me as needed.The price was reasonable (I had three other quotes) and I was well informed of all my options and warranties.Overall I was concerned that a roof was going to be some big hassle, and this process was seamless.Highly recommended, I see why the reviews are so good. Keep up this level of quality!!! It’s something all companies should aspire too! Thank you very much!
