Grimsby, ON Home Exterior Specialists

If your home is starting to show some wear, or you just want to get ahead of things before they become a real headache, Gerry's Roofing & Siding is here to help. We've been a family-owned business serving Grimsby and the broader Hamilton region since 1980, and with more than 30,000 projects under our belt, we know this area's homes inside and out.

That kind of experience adds up. We've worked on properties up and down these streets through every kind of weather, and we've seen firsthand what holds up and what doesn't. When you call us, you're not getting a call center or a rotating roster of subcontractors. You're getting a team that takes pride in their work because this is our community, too.

A Complete Approach to Exterior Work 

Most of our projects cover more than one section of the home. When you're already investing in your exterior, it makes sense to look at the full picture. Here's what we offer.

Roof Replacement & Repair

Your roof does a lot of heavy lifting, especially in a climate like Grimsby's. Lake-effect snow, ice damming, and freeze-thaw cycles put stress on roofing systems, which is why we look beyond just the shingles. We install a few types of roofing:

• Asphalt shingles (IKO) for reliable, budget-friendly performance

• Metal roofing (Ontario Metal Products) for homeowners focused on longevity

• Flat and rubber roofing (Euroshield) for low-slope or modern applications

Before recommending anything, we’ll take a close look at your ventilation and underlying structure. That way, we're fixing the root cause, not just patching over it.

Window & Door Replacement

Drafts, condensation, and windows that stick or warp are signs your current ones are working against you. We supply and install vinyl windows through Del Windows and Doors, built to keep your home efficient through every season.

The same goes for doors. A poor fit or failing seal affects both comfort and curb appeal. We offer entry and patio doors and install them all with the same attention to fit and finish, regardless of style or budget.

Siding Installation & Replacement

Good siding helps regulate moisture, supports insulation, and preserves your home's structure year after year. We carry several options depending on your priorities and style:

• Vinyl siding for low maintenance and a wide range of looks

• Steel and aluminum siding for areas that take more of a beating

• Fiber cement siding (James Hardie) for a more refined finish

• Composite options through Royal Building Solutions

Additional Services We Offer

Some of the most important parts of your exterior are the ones most people don't think about until something goes wrong. We install all of the supporting components that keep water, light, and airflow working in your favour:

• Skylights and sun tunnels (Velux) to bring more natural light inside

• Gutter replacement (Gentek) to manage water runoff

• Gutter guards (Alu-Rex) to cut down on maintenance after heavy rain

• Soffit and fascia to protect your roofline and keep ventilation flowing

Frequently Asked Questions

What roofing materials do you install?

We work with IKO asphalt shingles, Ontario Metal Products metal roofing, and Euroshield flat and rubber systems.

Do you offer payment plans?

We do, for qualified projects. We'll go over all available financing options with you once we understand the entire scope of your home renovation.

Can I tackle my exterior in phases?

Absolutely. Starting with the roof and returning for siding or windows later is a common approach. We'll help you map it out so everything works together when it's all said and done.

How does ice damming affect homes in Grimsby?

Ice dams form when heat escapes through the roof, melting snow that refreezes at the edges. It's a common issue near Lake Ontario.

Let’s Take a Look at Your Home

Grimsby homes face the same seasonal challenges year after year, and working with a company that's been through it all makes a difference. If you're looking for a roofing and exterior contractor who can take on the whole project, not just one piece of it, we're ready to help.
