Replacing shingles on a King Township house doesn't need a building permit, but check the zoning by-law, and hire only a crew trained to work at heights. Roofers aren't licensed in Ontario, so you vet them yourself.
A King City, Nobleton or Schomberg house is rarely a simple gable. Estate homes tend to have long rooflines, several valleys, dormers, a chimney or two and a roof pitched steeply enough that nobody should be walking it without proper gear. That changes how you plan a small repair: not the shingle itself, but who goes up, what they stand on, and how you keep a missing-shingle fix from becoming a leak you find in February.
Do you need a permit to repair a roof in King Township?
For shingles, no. The Township of King's building permit page lists "replacing roof shingles on a residential dwelling" under work that does not require a building permit. The same page says you must still comply with all applicable law, including the Township of King Zoning By-law. The page doesn't mention eavestroughs, so a plain like-for-like gutter swap is not something the township has ruled on in writing. If you are changing the roof's shape, adding a dormer or reframing anything, that is a different job, and the Building Division is the place to ask before you start. A short phone call costs nothing.
The safety rule that matters most on a big roof
The Ontario government's hiring-a-roofer guidance says roofing workers must be trained to work safely at heights, trained in workplace-safety hazards, and protected when working more than three metres (10 feet) above the ground. Since April 1, 2017, roofing contractors must have a working at heights training card. Most two-storey King Township homes have eaves above that height, and the ridge is well above it.
So ask the question plainly before you sign: how do you train and equip your workers, and can I see the working at heights cards? The same guidance says not to hire a contractor who can't confirm their workers are trained and properly equipped. This protects the person on your roof first, and it protects you from a dispute if something goes wrong on your property.
Roofers aren't licensed, so vet them yourself
Roofing contractors are not licensed by the government in Ontario. Unlike an electrician, there is no registry to look up. The province suggests checking the Consumer Beware List and the Better Business Bureau, getting at least three written quotes with materials and labour itemized, and asking for three references from current, recent and past jobs. If a contractor refuses to give references, the guidance says not to hire them. On a rural road, a local business also makes references easier to check.
What to put in a roofing contract
- The contractor's details, a written description of the job, the quote, a schedule and the total with taxes.
- Payment terms and the deposit. The province's guidance says to limit a deposit to 10% and not pay in full until the work is done.
- Who cleans up, who protects your gardens, and who pays if your neighbour's property or yours is damaged. On a big lot, ask where the dumpster and truck will sit.
- Warranty details, including who backs the material warranty. Some manufacturers require certified installers for the warranty to apply.
If a roofing contract of $50 or more is signed in your home, you have a 10-calendar-day cooling-off period. You can cancel for any reason without fees. If work has already started, you still pay for the work done and materials used. Be wary of anyone who claims damage without showing photos of it, and of tax-free deals that leave you without a receipt.
Eavestroughs and ice dams: fix the cause, not the symptom
Large rural roofs shed a lot of water and hold a lot of snow, so eavestroughs matter. Check for sagging runs, loose spikes or hangers, open seams and downspouts that dump water against the foundation. On a house with a well and septic system, a downspout that sends roof water toward the wellhead or the tank area is worth redirecting, since both sit on your own land.
Ice dams are the winter version of the same problem. Building-science sources broadly agree on the mechanism: heat escaping from the house warms the roof deck, melts snow, and the meltwater refreezes at the cold eave. The usual fixes are more attic insulation, sealing air leaks such as ceiling light boxes, the attic hatch and plumbing vent chases, and adequate ventilation. Clearing gutters helps in the short term, but it treats the symptom. If you see icicles year after year at the same spot, ask whoever looks at your roof about the attic as well.
Quick answers
Do I need a permit to replace shingles in King Township?
No, King Township lists replacing roof shingles on a residential dwelling as work that doesn't need a building permit. You must still follow the zoning by-law and other applicable law.
Are roofers licensed in Ontario?
No, the Ontario government doesn't license roofing contractors. Check references, the Consumer Beware List and written quotes yourself.
Do roofers need safety training in Ontario?
Yes, roofing workers must be trained to work safely at heights and protected when working more than three metres, or 10 feet, above the ground. Ask to see proof.
What causes ice dams on a roof?
Heat escaping from the house melts snow on the roof, and the meltwater refreezes at the cold eave. More attic insulation and air sealing address the cause.
How much deposit should I pay a roofer?
Ontario's hiring-a-roofer guidance says to limit a deposit to 10% and not pay in full until the work is done. Get a signed receipt for anything paid in cash.
Before the first shingle comes off
Photograph the damage, get three written quotes, confirm the training cards, and keep the deposit small. For a small repair on a big roof, those four steps matter more than the shingle brand. If you want help finding a vetted craftsman, Rhodex can price the job.
