horrible experience with the company! the estimator Tyler just disappeared after signing the contract, and project manager Doug said that different workscope he got, if not same as the one he received, he charge me almost double ! back and forth with bunch of emails to both guys, Tyler never ever responded! what services they delivered to the customer! Now i am stuck in the coming rain!

The team from Custom Contracting Roofing did a fantastic job on our roof. They were friendly, professional, and made sure everything was completed smoothly. They kept the worksite clean each day and were always available to answer our questions or address any concerns. We wouldn’t hesitate to recommend them to others.

I live in Upper Hamilton and just had Custom Contracting replace my roof. They arrived on time, worked quickly, and did an incredible job—every shingle is straight, and they even left the yard clean. Their work comes with a solid warranty, so I feel confident it will last.
A friend of mine referred me to them and got a nice bonus through their referral program. I’m so glad she did—these folks really know roofing. If you need a new roof in Hamilton, give Custom Contracting a try!
