Know What’s Going On Before You Decide

A curling shingle, a water stain on the ceiling, a rough storm that just blew through: any of these can leave you wondering how worried you should actually be. It's tough to know from the ground whether you're looking at a minor fix or something bigger, and guessing isn't a great starting point for a decision that costs money either way.

That's exactly why an inspection comes first at Gerry's Roofing & Siding. When you call us about a roofing concern, we don't jump straight to a quote. We’ll climb up, take a look at what's going on, and figure out how the different parts of your roof work together before we recommend anything. More than 45 years on Hamilton-area roofs means snow, ice, wind, and our freeze-thaw winters hold no surprises for us, and we know where they tend to leave their mark.

What Our Roof Inspection Covers

A roof inspection isn't a glance from the driveway. Depending on your home and what brought us out, our technicians work through several parts of the roofing system, including:

Shingles and Roofing Materials: We’ll look for missing shingles, granule loss, cracking, and edges that have started lifting or curling.
Underlayment and Decking: Where we can access it, we’ll check for moisture, warping, rot, or signs that water has gotten underneath.
Nails, Fasteners, and Seams: We’ll watch for raised or loose fasteners and separated seams, since either one gives water an opening it doesn't need.
Chimneys, Skylights, and Vents: Flashing and sealant around anything that pokes through the roof are common entry points for leaks.
Eavestroughs and Downspouts: Clogged or loose eavestroughs can push water toward your foundation, siding, or wherever gravity takes it.
Attic Conditions: When we can get inside, we’ll assess for staining, condensation, insulation problems, and signs of poor airflow.
Flat and Low-Slope Sections: We'll trace where water pools and how long it lingers, because that's usually where a flat roof starts to fail first.

None of these live in isolation. Poor drainage speeds up wear near the roof's edge, weak ventilation can lead to moisture and ice damming, and a gap in the flashing can let water in long before the nearby shingles show any sign of trouble.

Different Materials, Different Places to Watch

Asphalt shingles don't age the same way a flat membrane does, and metal panels bring their own set of challenges. Gerry's Roofing & Siding works with a variety of roofing types, and we adjust our approach based on what's on your house.

Because we install IKO asphalt systems regularly, we know what a shingle looks like before it starts failing. Our work with Euroshield rubber roofing means we're familiar with how that membrane ages differently than a torch-down or EPDM system. And our experience with Ontario Metal Products metal roofing means we know where a panel seam or fastener is likely to give first, long before it becomes a leak.

That's the kind of knowledge that gets missed on a rushed once-over. We’ll check the specific spots where each material tends to struggle rather than run through a generic list.

The Warning Signs Worth Paying Attention To

You don't need to diagnose anything before calling us. Most homeowners reach out simply because something changed and they want to understand why. Here are some of the more common reasons Hamilton homeowners reach out:

Missing, cracked, curled, or otherwise damaged shingles
A water stain on a ceiling or wall
A leak that keeps coming back, or one that just started
Damage after a windstorm or a rough stretch of weather
Ice building up along the eaves every winter
Shingle granules piling up near your downspouts
A roof that's 15 years or older and hasn't been checked recently
Wanting a clear answer on roof condition before listing your home

Some of these show up overnight after a storm, while others creep in slowly over a few winters before you notice them. If any of this sounds familiar, it's worth having someone take a look before the next freeze-thaw cycle makes it worse.

How We Turn Concerns Into Answers

At Gerry's Roofing & Siding, there's nothing complicated about how we run an inspection. You'll know what's happening from the moment we arrive to the moment we hand you an answer.

Explain

Describe what you've noticed, whether it's a leak, a stain, or storm damage from last week. That one detail points our crew toward the right section of the roof before we even climb up.

Assess

We'll inspect the roof's accessible sections and follow up on anything connected to what you've reported. If your attic is accessible, we'll inspect it for moisture, staining, or ventilation issues.

Discuss

We'll lay out the roof's condition without the jargon, pointing out anything worth addressing and what your options look like from there. And if a photo helps make the case, we'll take one.

Making Sense of the Next Step

What we find determines the path forward. A localized culprit, such as a section of damaged flashing or a worn patch of shingles, typically gets fixed with a targeted repair. But when the wear is spread across the whole roof, the leaks keep coming back, or the roof is old enough that it's on borrowed time, replacement becomes the more practical solution.

Either way, we'll explain the reasoning behind our recommendation and put together a quote for the work. Payment plans are available for qualifying projects, so budget doesn't have to be the reason a needed repair gets put off. You'll leave the conversation knowing not just what's wrong, but what your options look like.

Frequently Asked Questions

Visible shingle damage, water stains, active leaks, storm damage, recurring ice dams, or a roof that's aging without a recent checkup are all reasons to call. Even without an obvious problem, a roof around 15 years or older is worth a look.

We don't offer inspections as a separate paid or free service. They're part of our quote process. When you call about a concern, we'll assess the roof, explain what we find, and provide a free quote for any recommended work.

Freeze-thaw cycles gradually widen openings, while snow, ice, wind, and spring melt put extra stress on shingles, flashing, and drainage.

In most cases, yes. We'll look at whether the damage is contained enough for a repair, or if age and broader wear point toward replacement, and explain the reasoning either way.
