The Story of Your Home Starts at the Top
A roof problem rarely shows up at a convenient moment. It could be a stain that showed up on your ceiling after the last storm, a few shingles that look worse than they used to, or a roof that's simply hit the age where replacement is on your radar. Wherever you're starting from, you deserve a straight answer about what your roof needs, not a sales pitch dressed up as advice.
Gerry's Roofing & Siding has been working on Hamilton homes since 1980. We're family-owned and locally operated, and we've picked up more than 45 years of field experience along the way. That means when we inspect your roof, you’ll get honest advice, an accurate quote, and a team that treats your home like its own. Simply put, we know local roofs inside and out, and we’re here to make sure yours keeps doing its job.
A Better Way to Decide What Comes Next
Your roof's needs change depending on where it is in its lifespan. Some call for a repair, while others call for a full replacement. And if you're not sure which category you fall into, a closer look at the roof itself usually clears things up fast.
Once a roof has reached the end of its service life, minor repairs stop being worth it, and replacement lets us address the whole system at once. We'll remove the old roofing where needed and install a new system chosen for your home's design, pitch, and your own plans.
Not every leak means you need a new roof. Flashing issues, ice damming, isolated wear, and storm damage can often be handled with a focused repair rather than a tear-off. We'll track down the source instead of patching the symptom you can see, then explain what we found.
If you're not sure what condition your roof is in, an inspection gives you somewhere to start. This helps most when you've spotted a leak, your roof is older, or you're trying to decide if more repairs still make sense financially. An honest look today can save you from guessing later.
Four Seasons, One Hardworking System
Hamilton roofs earn their keep every year. Constant freeze-thaw cycles put materials through repeated expansion and contraction, and heavy snow accumulation sets the stage for ice damming along the roof edge. Leaks are one of the most common reasons homeowners call us, especially once an older roof starts developing weak spots around penetrations or flashing.
Local experience counts here because none of this is new territory for us. After four decades on Hamilton roofs, we've learned how asphalt, metal, and rubber systems each age in this climate and where trouble tends to start. That history shapes every recommendation we make. We won't push you toward a replacement your roof doesn't need yet, but when the signs point that way, we'll tell you why and help you pick a system that's ready for what comes next.
Choices That Go Beyond the Shingles
Picking a roofing material isn't something you can settle with a single go-to answer, and it isn't the only decision on the table either. Roof pitch, architecture, upkeep, and how much natural light you want inside all play a part, which is why we carry several manufacturers and a few add-on options rather than pushing every homeowner toward the same setup.
Asphalt Shingle Roofing
Asphalt shingles give homeowners a familiar look, dependable performance, and plenty of colours and profiles to choose from.
Euroshield Rubber Roofing
Euroshield rubber roofing is made from recycled materials and gives homeowners a distinct alternative to conventional shingles.
Metal Roofing
Metal roofing suits homeowners who value longevity and less upkeep, and we install Ontario Metal Products systems made for Southern Ontario weather.
Flat & Low-Slope Roofing
Flatter rooflines, like those on additions, need their own approach to materials and drainage instead of a standard steep pitch.
Skylights & Attic Insulation
Natural light changes a room fast, but a leaky skylight undoes that benefit just as quickly. We install Velux skylights and flash every seam.
Velux Sun Tunnels
Velux sun tunnels bring daylight into tighter spots without needing a skylight, and we can add one while we're already on your roof.
Attic Insulation
Owens Corning blown-in insulation improves how your attic and roof perform together, which matters most once colder months set in.
Whatever combination serves your home best, we'll go over the tradeoffs with you before anything goes on the roof, so you're never guessing at what you're paying for.
More Control Over a Major Investment
A roof is a major investment, and you shouldn't have to commit to one without a clear picture of the scope and cost. Gerry's Roofing & Siding offers payment plans for homeowners who'd rather spread costs out over time instead of paying it all upfront. Details are worked out during the quoting process, so you'll have the terms in hand as soon as the estimate is finalized.
We also work all year long. A leak in January isn't any less urgent just because most people associate roofing with warmer months, and we stay available whenever conditions allow us to get the work done properly. Planning ahead beats scrambling after the fact, every time.

Frequently Asked Questions
It depends on the house and what you're hoping to get out of the roof. IKO asphalt shingles suit most pitched residential roofs, Ontario Metal Products metal roofing appeals to homeowners looking for a longer-term system with its own upkeep routine, and Euroshield rubber roofing offers another option for applicable roof designs.
Age matters, but it isn't the whole story. Asphalt roofs typically last somewhere between 20 and 30 years depending on the material, installation, ventilation, and exposure over that time. Recurring leaks, widespread shingle wear, heavy granule loss, or repair after repair usually point toward replacement. More isolated damage can often be fixed instead.
Yes! Payment plans are available for homeowners who'd rather spread project costs out instead of covering everything at once. Visit our financing page for more details.
It depends on the size of the roof, the material, existing conditions, and the weather. Once we've seen your roof and confirmed the scope, we'll give you a realistic timeline before work starts.
