Top notch crew led by David. Very professional, excellent work. On time on budget and quickly done. Would not hesitate to give 5 ⭐️

GEXR did a complete roof replacement of our house 3 years ago. This included a consultation with Dave a couple of times to discuss the project to remove all the underpinning (plywood), replace the shingles, soffit, fascia and gutters and downspouts. Service was professional and work were excellent, led by Taylor, cory, and their teams. Given it was a full roof replacement and done during Covid when materials were experiencing supply chain issues, the total price was higher than normal, but the workmanship was worth it.

A five-star rating isn’t high enough for GEXE Extreme Exteriors and Dave Spalla and his Team! From our first meeting, Dave’s expertise and professionalism stood out. He was thorough, honest, and genuinely nice — qualities that are rare these days. After inspecting our roof, Dave asked to check the attic and quickly uncovered major issues: poor venting, disconnected furnace stack and bathroom fan, and significant mold caused by a previous roofer’s negligence. We got three quotes — one company didn’t even call, and another ignored our concerns. GEXE’s price was in line with the others, but their attention to detail was on another level. We’re thrilled with our beautiful new black matte roof (50-year transferable warranty), upgraded venting, insulation, and properly reconnected stack and fan. The cost ran a bit higher due to mold damage, but it was absolutely worth it. Dave’s crew was respectful, efficient, and left our property spotless. We highly recommend GEXE Extreme Exteriors and Dave Spalla’s team — you won’t be disappointed!

David was there for me within the hour late at night to cover up my skyligh that crashed. It was snowing and windy that night. A few days later, he was able to put a new skylight in, which looks very nice.

Hi Cecil It was our pleasure to help you. We can’t always promise service that fast, but we always do our best when emergencies happen. I’m glad we were able to get your skylight secured that night and have the new one installed within just a few days. Your roof overall looks solid, so I don’t expect to hear from you anytime soon , but if you ever need anything or any other exterior services, you know where to find us. Thank you again for the kind review. GEXR Extreme Exteriors Inc.

I recently had a roof replaced by a team of GEXR Extreme Exteriors Inc. professionals, and I must say, they were absolutely outstanding. The crew's effectiveness was truly impressive, and their dedication to the project was commendable. From the initial consultation to the final installation, every step was executed with precision and care. The quality of the workmanship was exceptional, and I couldn't have asked for better results. I highly recommend this company to anyone in need of a roof replacement.

Thank you kindly for the amazing review, Darius. If there were a place where contractors could rate homeowners, you’d absolutely get a golden five star from us. We really appreciate when people recognize the effort and detail that go into doing a roof properly. Unfortunately, many only understand the difference of a good roof after a bad experience elsewhere, so your appreciation truly means a lot. And I’ve got to say, that tip about the Village Bake Shop in Whitby was a game changer! I’ve been back more times than I’d like to admit, might be gaining a few pounds because of you. The hospitality you showed our crew also was incredible, and I can’t thank you enough for that and I have a lot of respect for homeowners that treat their workers well. Wishing you, your wife, and your family all the best and don’t be a stranger. It was an absolute pleasure working with you both. -- David Spalla GEXR Extreme Exteriors Inc.

David was knowledgeable and explained step by step what needed to be repaired. It was a relief to work with a trustworthy contractor after paying another Contractor $1,000 previously to fix the same problem. David exceeded expectation and worked Overtime to ensure the roof was repaired before the next rain storm! ...and sent me photos step by step! Thank you David! Thank you, thank you

Thanks so much for the kind words! I know how frustrating it can be when things don’t get fixed properly the first time, I hear it too often so I’m really glad we got this figured out for you. I always try to keep homeowners in the loop with photos and updates so you can see exactly what’s happening up there. Appreciate the trust and support, it really means a lot.

Had a leak after a storm. GEXR’s team were excellent to work with and came promptly and completed the repair quickly and cost effectively. Supper friendly staff would recommend GEXR to anyone in need of repairs or full roof replacement. Thanks again!

GEXR go to extreme measures to protect your property and ensure quality is built-in! We just had our roof, soffits, fascia, eaves trough replaced with insulation added to the attic. Right from the start we knew GEXR Extreme Exteriors Inc. was going to be our company of choice. Dave thoroughly inspected our home and provided a very detailed estimate with a clear understanding of what was needed. He was very professional, knowledgeable and we never once felt pressured on our decisions. His team upgraded our home always focused on protecting our gardens, house, cleanliness and quality with a very personable touch. We highly recommend GEXR for your roofing needs. Great job!

From start to finish, you were a pleasure to work with, trust me, the crew loved how involved you were (and how you always had a few opinions to share before seeing the finished product 😉). It made the whole project feel like a true team effort. Customers like you, who truly appreciate the work and detail that goes into a project, make what we do incredibly rewarding. We’re so glad you trusted us with your home, and we couldn’t be happier with how everything turned out. On behalf of myself and the crew, thank you for making the job fun as well as rewarding, Bill!

My wife and I are trying to sell our house and it was a bit of a time crunch for us to get the shingles done before the season was over. GEXR responded quickly to my initial call for service and the workers were at my house literally the next day for a quote. They began work the day after that and finished the job in just 2 days, working in the extreme heat. Jason and Tyler did an amazing job not only with the installation of the shingles, but the removal and cleanup process as well. If it wasn’t for our beautiful new shingles there’s no evidence that a crew was here at all! I highly recommend GEXR for anyone who needs their roof done if you want fair prices, friendly and fast service, and a roof to be proud of!

Evan, we really appreciate you taking the time to share this. We know how stressful selling a home can especially under a tight timeline so we’re glad we could make the process smooth for you. Jason, Tyler, and the crew will be thrilled to … More

David just finished a siding job at my home, which was admittedly small but highly nuanced, and knocked it out of the park! He was respectful, highly communicative and completed the job on schedule; also, priced fairly. I recommend him for anyone seeking timely, quality work! 🙏🏻 …

If you're looking for decent, honest, polite people, that go that extra mile for you and are incredibly professional - these are your people. Dave replaced part of my roof and I'm asking him back for more work to be completed. I highly recommend GEXR, you're in safe hands. Thanks a million for all of your, and the teams, hard work !

We can’t speak highly enough of Dave and his crew! From the very beginning Dave was honest, transparent and answered all of our questions promptly. Our roof and attic seemed like a daunting task but Dave was reassuring throughout the …

We called on a Sunday night, Dave Spalla was here by noon on Monday! Dave was very informative, extremely thorough because he checked our entire roof and garage. He let us know what needed done, and the approx remaining life expectancy of our roof. He went above and beyond. We would highly recommend him to anyone needing exterior work done. He also does siding and eavestroughs. We could have not asked for a better experience! 5 stars across the board.
