Roofing in Hamilton, Ontario

Beaudry Roofing is a Hamilton company. Waterdown has been part of the City of Hamilton since amalgamation in 2001, and that's where the trucks start every morning.

Century homes in the lower city, post-war bungalows on the Mountain, and the newer stock through Ancaster, Dundas, Binbrook and Stoney Creek.

Getting to Hamilton from Waterdown

Hamilton isn't a service area we drive out to — it's home. Waterdown sits inside the city's boundary, so Dundas, the west end and the Mountain are all fifteen to twenty-five minutes out, and Ancaster, Stoney Creek and Binbrook are an ordinary working distance rather than an exception. Hamilton is also the most varied roofing city in this region by a distance: a 1905 brick two-and-a-half storey in Durand and a 2010 build in Binbrook barely share a technique.

Hamilton's roofs come in three very different eras

Most cities have a dominant housing stock. Hamilton has three, and the right way to roof one is wrong for another.

The lower city: Durand, Kirkendall, Strathcona, Corktown, Crown Point, Gibson

Pre-1930 brick, steep pitches, and — this is the part that catches people out — original board sheathing rather than plywood. The deck under these roofs is gapped one-by-six planks, laid for cedar shingles a century ago. Modern asphalt shingles need continuous support and reliable nail holding, so a proper job here often means sheeting the whole roof over in plywood before a single shingle goes on. That is a real cost, and it's the single biggest reason two quotes on the same Hamilton century home can be thousands apart: one of them is planning to nail into the gaps and hope.

These houses also very often have a flat or low-slope rear addition, which is a completely different roof needing a self-adhered SBS membrane rather than shingles. A quote that prices the whole house as "shingles" hasn't looked at the back.

The Mountain: Westcliffe, Rolston, Gourley, Hill Park, Templemead, Huntington

Post-war through the 1970s, mostly bungalows and back-splits on generous lots. Straightforward roofs, good access, and the most common finding up here is ventilation: decades of added attic insulation with no matching increase in soffit intake. The roof stops breathing and the shingles age from underneath. Fixing intake during a replacement costs very little; going back to do it afterward means lifting work that's already paid for.

Ancaster, Dundas, Binbrook and Stoney Creek

Everything from stone-and-brick older homes in Dundas through 1990s Ancaster to the 2000s build-out in Binbrook and upper Stoney Creek. The newer subdivisions are now hitting their first replacement, and they tend to have complicated roof geometry — hips, valleys, dormers and cut-up sections — which drives waste and flashing time far more than square footage does.

What actually goes wrong on Hamilton roofs

  • Nails that never had anything to bite. On board-sheathed century homes, shingles nailed across a gap between planks hold until the first serious wind. If your roof is losing shingles in patches rather than at the edges, this is usually why.
  • Flat rear additions treated as an afterthought. Low-slope roofs on the backs of lower-city homes fail differently from shingles and need membrane, not a patch of asphalt. They're also invisible from the street, which is how they end up neglected until the ceiling below them stains.
  • Chimneys, and lots of them. Older Hamilton housing is full of masonry chimneys, and the joint where brick meets roof is where roofs leak. Re-using tired step and counter-flashing on a new roof is the most common reason a brand-new roof leaks in its first year.
  • Access on narrow lots. Lower-city streets with no driveway, a rear lane, or a neighbour's wall a metre away change how the tear-off gets staged and how the debris comes down. It doesn't make the job harder to do well, but it does need to be priced honestly rather than discovered on the morning.
  • Escarpment wind at the brow. Properties along the edge, above Dundas and across the upper Mountain, take wind loading that streets a kilometre away don't.

Permits, heritage and re-sheathing in Hamilton

Re-shingling an existing roof in Hamilton does not normally need a building permit — nothing structural changes. The honest caveat, and it matters more here than in most cities, is re-sheathing. If your century home needs plywood over the original board deck, that may be treated differently from a straight shingle swap. Justin raises it at the quote, and the City of Hamilton building permit pages are where to confirm it for your address.

Heritage is the other Hamilton-specific one. Parts of Durand, Kirkendall and the surrounding lower city contain properties designated under the Ontario Heritage Act, and a designated property can need heritage approval for changes to a visible exterior surface — including, sometimes, a change of roof material or colour. If you're not sure whether your house is designated, that's worth checking with the city before you commit to a shingle.

And the baseline for any Hamilton contractor, heritage or not: WSIB coverage and liability insurance. An uninsured crew on your roof makes their injury your problem. Beaudry Roofing is WSIB covered and fully insured, the crew works for Beaudry rather than a subcontractor, and the paperwork goes out with the quote on request.

Roofing questions from Hamilton homeowners

Why are quotes on my Hamilton century home so far apart?

Usually the deck. Pre-1930 homes here were sheathed in gapped boards for cedar shingles, and asphalt needs continuous support. One quote is pricing plywood over the whole roof and the other is planning to nail into what's there. Ask every contractor directly what they intend to do about the board sheathing — the answers will explain the numbers.

I have a flat roof on the back of my house. Do you do those?

Yes. Low-slope and flat sections get a self-adhered SBS membrane rather than shingles, and they're quoted as their own part of the job. The flat rear addition on a lower-city Hamilton home is one of the most commonly ignored roofs in the city, because you can't see it from the street.

Is Waterdown part of Hamilton?

Yes — it has been since the 2001 amalgamation, when Flamborough became part of the City of Hamilton. That's where Beaudry Roofing is based, so Hamilton isn't an outlying service area for us, it's home.

Do I need a permit to re-roof in Hamilton?

A straight shingle replacement normally doesn't. Structural work does, and re-sheathing an entire century-home deck can be treated differently from a simple shingle swap. Justin raises it at the quote. If your house is designated under the Ontario Heritage Act, changes to visible exterior surfaces may need heritage approval as well — worth checking with the city before you pick a shingle.

Do you work on the Mountain and in Ancaster, Dundas and Stoney Creek?

All of them, plus Binbrook. They're inside the City of Hamilton and inside our normal working area. The Mountain and Dundas are the shortest runs from the shop.

My shingles are blowing off in patches, not at the edges. What does that mean?

On an older Hamilton home it usually means the nails didn't have solid wood behind them — they went through a gap in the board sheathing. Patching more shingles onto the same deck buys you until the next storm. It's worth having someone actually look at the decking rather than just the shingles.
