Professional Roofing Contractor in Milton, ON
Limited-Time Offer!
6 Months No Interest on all Roofing, Siding, Gutters, Window and Door Projects through May!

A roof isn't something most people get excited about. It's not a kitchen renovation or a backyard makeover. But when it's doing its job, it's protecting everything underneath it, and that's exactly why it matters more than almost anything else in your home.
The truth is, most homeowners don't think about their exterior until something forces them to. A leak after a heavy rain. Siding that's starting to look a little rough around the edges. A draft near a window that wasn't there last winter. By the time those things show up, the issue has usually been building for a while.
Gerry's Roofing & Siding has been the company Milton homeowners turn to when they're ready to stop putting it off. We’ll take care of the hard work so you can rest easy knowing your investment and your family are safe and dry.
Our Full-Service Exterior Work
One of the things homeowners appreciate most is being able to handle everything through one team. Once we're on-site, it's natural to notice a few other areas that could use attention, and coordinating it all together saves time, money, and the headache of managing multiple contractors.
We offer a variety of exterior services across Milton, including:
Roofing: From localized repairs to system replacements, we work with asphalt shingles, metal, and flat roofing systems designed to withstand Ontario's toughest seasons.
Siding: We install Royal Building Solutions vinyl and James Hardie fiber cement, two of the most dependable options for homes in this climate.
Windows: Aging windows can drive up energy costs before homeowners notice. We install Del Windows & Doors products in a range of styles and configurations.
Doors: From front entry systems to patio doors, we handle replacements with close attention to fit, sealing, and performance so everything functions the way it should.
Gutters: Water that isn't managed properly is one of the sneakier causes of exterior damage. We install metal gutters and Alu-Rex gutter guards to keep things flowing.
Soffit & Fascia: These components play a bigger role than most people realize, supporting attic ventilation and moisture management.
Skylights & Sun Tunnels: For rooms that never quite get enough natural light, Velux skylights and sun tunnels are a straightforward solution.
Good exterior work isn't just about how things look on day one. It's about how your home performs five, ten, and fifteen years down the road. Every product we install and every service we offer is chosen with that in mind, because a home that's built to last is worth a lot more than one that just looks beautiful at first glance.

Frequently Asked Questions
Does winter weather affect roofing timelines?
Not necessarily. We work year-round and plan carefully for cold-weather conditions, using materials and methods suited to the season. If your roof needs attention in winter, it’s still worth reaching out for a quote.
Do you offer payment plans?
Yes, we do. The specifics depend on the scope of your project, but we’ll walk through the available options during your consultation.
How do I know whether I need a repair or a full replacement?
That depends on the material's age, the extent of the damage, and how the rest of the system is holding up. In some cases, a targeted repair makes sense. In others, replacement is the better long-term solution.
Can I get a quote without feeling pressured to move forward?
Absolutely. We provide quotes to help you understand the scope of the work, the cost, and your options. The goal is to give you a clear picture of the project, not to pressure you into a decision on the spot.
