F Con and team were reliable and good communicators. We’ve hired them three times. Once for remediation and ceiling resurfacing throughout, next for full paint throughout and a third time for removing ceiling texture from closet door frame/tracks.

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!

We hired F-Con to replace our entire tile roof. They were able to start immediately and did a lovely job. We were very happy with the selection of tile choice so we could match to our paintwork perfectly. Moreover when we required the house tented for termites soon after and the tenters broke some of tile in the process, F-Con came out and fixed that for us free of charge.

I can’t recommend Cameron and his team at F-Con Roofing highly enough. From start to finish, the entire experience was professional, honest, and hassle-free. Cameron was great to work with—he communicated clearly throughout the project, showed up when he said he would, and made sure every detail was handled the right way. The crew was punctual, respectful, and took pride in their workmanship. The quality of the finished roof exceeded my expectations, and they left the job site spotless when the work was complete. If you’re looking for a roofing company that stands behind its work and truly cares about customer satisfaction, F-Con Roofing is the company to call. Cameron and his team deliver exceptional craftsmanship and outstanding service. I wouldn’t hesitate to recommend them to anyone needing a new roof or roofing repairs.
