Weather-Ready Roofing & Siding in Guelph, ON
There's a lot riding on what's sitting above your head and wrapping around your walls. When a roof starts to fail, water is just the beginning. The damage that follows reaches your insulation, your framing, and every corner of your home's comfort. If you've been putting off an exterior update or if something has already gone wrong, Gerry's Roofing & Siding is the company Guelph homeowners have been calling since 1980.
We're a family-owned company with more than 30,000 completed projects and a Transferable Lifetime Workmanship Guarantee that covers the original homeowner for life and passes to a new owner for up to 20 years. That means one team, one guarantee, and no finger-pointing between contractors when questions come up.
Complete Care for Your Exterior
We handle every part of your home's exterior, which means you can tackle multiple upgrades at once without the hassle of coordinating separate contractors and overlapping schedules. Whether the priority is a failing roof, damaged siding, clogged eavestroughs, or a darker room that could use illumination, we can fold it all into a single, well-managed project.
Our services for Guelph homeowners include:
Roofing: From inspections and repairs to full replacements, every recommendation we make is shaped by a detailed look at your home's slope, structure, and condition.
Siding: With vinyl, steel, composite, PVC, and fiber-cement all on the table, we’ll help you narrow it down to the material that fits your home's demands and your taste.
Windows: Cold winters have a way of exposing windows that aren't pulling their weight. We install options built for this climate that keep heat in and noise out.
Doors: Entry and patio doors work harder than they get credit for. Every option we offer is engineered to stay secure and well-insulated through years of use.
Gutters: Water that has nowhere to go finds somewhere on its own. We install eavestroughs, soffits, and fascia to provide it with a path away from your home.
Skylights: For rooms that feel dim regardless of the time of day, a skylight or sun tunnel brings in consistent natural light without compromising the roof system around it.
Having one contractor oversee all of this isn't just more convenient. It also means every system is installed with the others in mind, so the places where your roof meets your siding, or where your eavestroughs meet your fascia, are never an afterthought.
Understanding the Impact of Local Weather
Ask any experienced contractor in this region, and they'll tell you the same thing: southern Ontario's climate is genuinely unforgiving on exterior materials. Snow accumulates, temperatures swing dramatically between seasons, and the freeze-thaw cycle does more structural damage over time than most homeowners expect.
Ice damming is a particularly common problem in Guelph. It starts when heat escapes through the roof, melting snow near the peak. That water travels down the slope and refreezes at the eaves, where temperatures are colder, and the growing ice can eventually push up under the shingles, allowing water into the home. By the time you notice staining on a ceiling or moisture near a wall, the damage is often already underway.
Strong ventilation, quality insulation, and precise installation are your best protection. The same principle applies to siding and windows, where substandard or aging materials can crack, warp, or lose their seals after years of exposure to Ontario's extreme temperatures. When the materials are engineered for cold climates, and the professionals installing them have spent decades working in those conditions, the results tend to speak for themselves.
