Great experience and couldn’t be more happier with his work and time. I left a message and received a call back the same day with the owner coming the next day to patch my roof that was leaking where an old pipe was. In our situation it was greatly appreciated to deal with someone that was very kind, professional, quick turnaround and also had great pricing.
I saw Poirier D Roofing finishing up a job on another house and went over just to ask about scheduling a quick fix for my siding in the future. Instead of just taking my info down, they came right over to my home, fixed it up temporarily to hold me over, and wouldn’t even let me pay them for their time! They were incredibly nice, fast, and helpful. I will definitely be using them for my upcoming roof replacement. Highly recommend Poirier D Roofing to anyone looking for honest, kind, and professional service!
Very happy with their work. Excellent service, well cleaned up when finished. Very nice people. Highly recommended

D Poirier Roofing arrived onsite for a site visit/consultation and within a week delivered the best looking shingle roof i have ever seen to date. The crew has excellent knowledge on roofing techniques and procedures and did a beautiful job! They stuck to the budget and i will be calling them for the next roof!
Darcy and his crew did a great job replacing the shingles and multi repairs on the roof deck, it was done in one day, on budget and left the yard very clean.

Darcy is reliable and dependable for his work . I totally recommend him
This company was able to accommodate my dad with what he needed as well as doing it on Saturday. We are pleased with the quality of work and the professionalism. Thank you!
Had Poirier Roofing do our side roof and front porch. From quote to finish they were on point. Showed up when scheduled, no delays. Communication was fast and clear - answered questions quick and kept us updated. Work looks great and they cleaned up well after. No surprises on price either. If you want roofing done right without the runaround, give Poirier a call.
Ty Poirier Crew! Highly recommend this company as they were on time, professional and made sure my place was clean afterwards, just like they came and went but with a much better roof! I'll be recommending D Poirier Roofing to everyone I know- 5 stars!
Darcy and his crew did a fantastic job on my roof. Clean up was fantastic no nails or paper lying around. Very professional I highly recommend Darcy and his crew.
We highly recommend Poirier Roofing. We had our roof replaced last April and couldn’t be more satisfied with the results. The crew was professional, punctual, and kept everything clean throughout the project.
Great experience, good customer service! Job well done!
Darcy did an excellent job on our commercial property in Cornwall. He was professional, reliable, and delivered top-quality workmanship from start to finish. The project was completed on time, and the attention to detail was outstanding. We couldn’t be happier with the results and would highly recommend Darcy to anyone looking for a skilled and trustworthy roofer. +++++
Darcy was professional, great at communicating and very reliable. Very happy with the roof and the service. Definitely recommend them.
Poirier was highly recommended to us and was quick to respond for an estimate. They did a great job and were very reasonable with their rates. Highly recommended!
We first hired Poirier Roofing back in 1997 to replace a roof in Cornwall, and since then they’ve completed several roofing projects for us over the years. Simply put, they are the very best in the SD&G area, hands down. Honest, hardworking, dependable, and committed to great old-school workmanship — the kind that’s becoming harder and harder to find. Every experience we’ve had with Poirier Roofing has been excellent, and we wouldn’t hesitate for a second to recommend them to anyone looking for quality roofing work.
Highly recommend! Did a fantastic job! Clean up was like they were never there no nails or paper very kind crew very professional! Five stars! ✨ 🌟

Poirier Roofing came out to me in Cornwall for a estimate on my roof. We decided to go with them and were happy that we did. Excellent workmanship, very tidy cleaned up after themselves. Very happy with the roof and would highly recommend Darcy and his crew. Thank you!!
I don't give 5 stars to anyone, however Darcy and his crew deserve more than 5 stars. I had scheduled another roofing company to do my roof. Something happened and it left me not having my roof done or a roofing company. I called Darcy, him and his crew came after they finished another job to give me a quote. The quote was done in less than 10 minutes. Any and all questions I had were answered. The quote I was given was very reasonable, especially when other companies quoted me double. Within 4 days my roof was done. Darcy had to leave for a bit so his crew continued to work on my roof. They were very professional. They were done in less than 4 hours, all the shingles, nails and plastic was picked up. I will hire them again next year for a small roof job that will need to be done. Thank you Darcy and thank you to your crew.
John came highly recommended by a good friend and he was spot on! He provided a detailed quote and discussed options for the job. After accepting his quote we scheduled the work. John and his team were punctual arriving early as promised. The job was completed on time and everything was done as planned. I kept an eye on the process and was impressed the way the team worked together to get the job done. The finished project came out excellent. My wife and I are totally satisfied with the work done. John made sure to discuss the work afterwards to ensure I was totally satisfied which I was. I am impressed with his knowledge and work ethic. His entire team is very friendly. Once the job was done all debris was taken away and made sure everything was cleaned up and nothing was damaged. We have beautiful gardens around the house and all was good. I highly recommend anyone looking to get their roof replaced to contact John. His work is top notch!
Estimate was right on and , they were here when they promised they would be, the crew he as are amazing and polite. Efficient all the way around
Darcy and his team did an amazing job! Were truly impressed with the workmanship and the timeline in finishing their work. We highly recommend their services!! Thank you
Poirier Roofing was chosen to do our shingle roof not because of the price (although they were the lowest of 3 quotes) but because Darcy was knowledgeable and he struck me as a real roofer. Darcy and his crew were punctual, meticulous in the work and conscientious in the cleanup. Everything went smoothly from start to finish. Highly recommended.
They did a fantastic job. Im very pleased with them. Highly recommended by me. Thank you.
They did a great job, and the price was lowest of the 3 estimate I received.
It took a while to find a perfect roofer to fix my house. I'm glad I finaly called poirier roofing. He was quick and polite. The charges were reasonable and im very happy with the service. I recommend him to all my friends.
Thank you so much for the great job you and your team did on our roof, we really appreciate it! I also really appreciate that you all worked safely and able to return to your friends and family!
