Time To Have Your Roof Replaced?
We know that homeowners hate having to replace their roofs. It's a task you wish would never come up and an expense you could avoid. But since you're here, it looks like it's something you can't put off any longer. It's time for your roof replacement. Say goodbye to unlicensed, fly by night, shady roofing companies. Say hello to Gerry's Roofing & Siding Inc. We're your trusted roofing company you can rely on.
Unfortunately, as much as we wish roofs would last forever, they don't. Are you noticing leaking, curled, broken, loose or missing roof shingles? It's time for a roof replacement. If the damage isn't that bad and your roof isn't that old, we might be able to repair your roof instead of you needing a new roof installation.

Our Roof Replacement Process
Over four decades ago, we started on a mission to create a different kind of roofing company in Hamilton. One that was built with strong core values that put people first. No high pressure sales tactics. No shortcuts. No shoddy workmanship. A roofing company that delivers an exceptional customer experience every step of the way.
We focus on 100% customer satisfaction because the rest falls into place naturally after that.
Leave nothing to chance with your next roof replacement.
Free, No Obligation Roof Assessment
One of our core beliefs is to educate our customers and provide them with all the information they need to make the best decision for their situation. This starts with honest, accurate, and reliable information in the form of a roof inspection.
The first step is for us to come out and look at your roof to properly assess the damages and provide you with specific details on your options. We offer free roof inspections at a time that works for your schedule. We always try to save our customers money and keep your roof cost down. If there is a way only to do repairs to fix the damage without having to do a full blown roof replacement, we'll try our best to accommodate that.
We offer an advisory sales process each step of the way, so you'll make the right decision that fits your needs.
No pushy upsell just honesty.

Schedule The Job For A Time That Is Best For You
We know you live busy lives, and replacing your roof can disrupt your home. So together, we'll work on a start date that will be easiest for you to minimize the impact on your daily life. Communication is one of our best strengths, so you'll be informed the whole way and never kept in the dark.

Efficiently Work To Complete The Job
Most roof replacements are completed in a day or two for the avg sized home. We'll show up when we say we will and work efficiently and quickly while not taking shortcuts on quality. Once we start, we're 100% committed to your project, and no other distractions will stop us from installing your new roof.

Detailed Cleanup Leaving Your Yard Spotless
We understand the importance of ensuring your yard is left in pristine condition after a roofing replacement job is completed. To that end, we take particular care in protecting your plants and shrubs before tearing off the old shingles and will pick up nails, metal objects and any other old debris from your lawn. We also remove all existing shingles, roof decking, underlayment and all the rest of the roof's materials and will place them in a dumpster we will take away when your roof replacement is complete.
Furthermore, we will conduct a thorough final cleanup and haul away all debris so that your property is left in perfect condition after the job is done.

Final Inspection With Your Project Manager
At the final inspection with your project manager for a roof replacement, our project manager will assess the quality of the work done, check the roof's overall condition, and make sure all the requirements have been met.
