Cameron and his crew will always work to make sure they are done on time and on budget for you. I have had a roof done by him and his company the the timeliness and attention to detail were above and beyond. I highly recommend he and his company to anyone that ever asks and those who don't.

F-Con Roofing just recently finished installing a new roof on our home. We could not be happier with the results. F-Con’s team of roofers were polite, professional, and their attention to detail was excellent. Cameron kept us informed at every step of the process leaving us with peace of mind knowing our home was in very capable hands. Thank you Cameron and your team!

Cameron and his crew @ F-Con were incredible. They did a full torch down roof replacement for us and it has been solid. Very satisfied customer.

Ryan Ash Google review · July 2026

Couldn’t be happier with the work F Con and Cameron did. Had some roof issues, called quite a few companies and they gave me the run around. Great communication and very easy to work with. Don’t waste your time with other contractors and companies.

Gino DeMarino Google review · July 2026

After interviewing 6 top roofing contractors we chose Cameron at F-Con and couldn’t be happier that we did. They by far had the best customer service, attention to details, products and craftsmanship, and at a great price. Every phone call and question was answered immediately and we are thrilled with the finish product.
