Roofing options and costs in Renfrew
Renfrew homeowners usually see roofing prices shaped by two things at once: an older housing stock and a four-season climate that is hard on shingles. With 76.4% of homes built before 1981 and 58.5% of households owning their home, a lot of local roofs are reaching the point where patching stops making sense and a full replacement becomes the better value. In town, that often shows up on the older streets around downtown Renfrew and near the river, where homes may have steeper pitches, tired flashing, and at least one past re-roof already hidden under the current shingles. That matters because two-layer tear-offs cost more, and older decking can reveal soft spots once the shingles come off.
In the Kingston–Pembroke economic region, labour is also priced around cold-climate realities: ice-dam protection at the eaves, better venting, and stronger underlayments are standard, not upgrades. Winters shorten the practical install season, so good crews book quickly and peak-season labour can climb. Spring and fall weather delays can also affect scheduling and lift rental costs, especially on steeper roofs. For Renfrew homeowners, that means a simple asphalt reroof may still land near the middle of the city’s price band, while a complex roof with valleys, skylights and chimney flashing can move fast toward the upper end. If you are comparing quotes for a house near River Road or in the downtown core, make sure each contractor is pricing the same scope. The table below breaks down the most common options and what you can expect to pay.

What affects the price of roofing in Renfrew
Two homeowners in Renfrew can get quotes that differ by 30–50% for what looks like the same roof, and that is usually because the scope is not actually the same. A small bungalow with a clean, walkable pitch and one layer of shingles is a very different job from a 2-storey home with dormers, chimneys and two layers that must be torn off. In this part of Ontario, snow load and freeze-thaw cycles mean contractors build in stronger ice-and-water protection and pay close attention to eaves, valleys and ventilation. Alberta’s hail belt pushes more demand for impact-rated shingles, while coastal BC’s rain and wind conditions make metal and premium synthetic underlayments especially attractive; those regional pressures influence product choices even when Renfrew’s own market is more focused on snow and ice control. Shorter install seasons in colder regions also concentrate demand into the best weather windows, so labour can climb during peak summer weeks. For example, a straightforward asphalt replacement near the lower end of the city range may land around $6,500 – $8,500, while a steeper roof with extra flashing and decking repairs can move toward $12,000 – $15,000 or more. On older homes, hidden rot can add several hundred to several thousand dollars once the shingles come off, especially if the roof has been leaking around chimneys or valleys for years. That is why a quote that looks cheaper up front is not always the better deal.
| Price Factor |
Why It Matters |
Cost Impact |
| Roof pitch and steepness |
A steeper roof needs more safety gear, slower work and sometimes staging or extra harness setup. |
Can add 10–25% to labour on difficult roofs. |
| Number of shingle layers to tear off |
Two layers mean more labour, heavier disposal and more time at the dump. |
Often adds $1,000 – $3,000 or more. |
| Total roof area in squares (1 square = 100 sq ft) |
Larger roofs need more shingles, underlayment, fasteners and labour hours. |
Pricing scales with size; every extra square increases material and labour. |
| Decking condition |
Rotted plywood or OSB must be replaced before new roofing goes on. |
Usually adds $80 – $140 per sheet installed. |
| Chimney, skylight and vent flashing complexity |
More penetrations mean more labour, more custom flashing and more leak risk if done poorly. |
Can add $350 – $1,500 depending on count and detail. |
| Ice-and-water shield coverage required |
Cold-climate roofs need robust protection at eaves, valleys and vulnerable transitions. |
Raises material cost, especially on low-slope or complex roofs. |
| Regional labour rates and length of the install season |
Colder regions have shorter workable windows, so good crews are busier during peak months. |
Can move a quote by several hundred to a few thousand dollars. |
| Material quality tier |
Standard, impact-rated and premium systems have very different product costs and warranty terms. |
Can separate a $6,500 – $9,000 job from a $12,000 – $18,000 job. |
Permits & regulations in Ontario
In Ontario, most like-for-like roof replacements do not need a building permit if you are simply removing old shingles and installing new ones on the existing roof structure. That said, permits are often required when the work goes beyond basic re-roofing. For example, replacing damaged roof framing or structural decking, changing a roof from pitched to flat, altering the roofline, or adding major structural supports can trigger permit requirements through the local building department. A second layer of shingles is another area to watch: if the existing roof already has the maximum allowed layers under the code and the contractor proposes adding more, that is not a routine re-roof and should be treated carefully. Contractors working on homes in Renfrew should also be carrying liability insurance, WSIB coverage where applicable, and manufacturer certification for warranty-backed installs. Do not accept verbal assurances. Ask for a certificate of insurance, a current WSIB clearance letter, and proof of training or certification from the product manufacturer or their approved program. For a homeowner, the simplest check is to confirm the contractor’s business registration online, then call the insurer named on the certificate to verify the policy is active. Next, request a WSIB clearance number or letter and verify it directly through WSIB’s online clearance system. If the company uses subcontractors, ask whether those crews are also covered. Before signing, make sure the quote states who pulls the permit if one is needed and who pays for it.
Choosing the right roofing material for Renfrew's climate
Renfrew’s climate is hard on roofs because it combines freeze-thaw cycling, snow load, wind exposure and long cold stretches that can create ice dams at the eaves. That means your material choice should not be based on looks alone. Standard architectural shingles are usually the right value for many homes here because they balance cost and performance well, especially on typical detached houses in town. They are a solid fit for the majority of Renfrew roofs if ventilation is corrected and ice-and-water membrane is installed properly. Impact-resistant shingles make sense when you want better resistance to wind and minor hail-related damage, or when an insurer offers a discount for upgraded materials; the premium is often 20–30% over standard architectural shingles, so it only pays back if you value the added durability or policy savings. For example, if a standard roof is priced at $8,500 – $11,500, the impact-rated version may land around $10,500 – $14,500, which can be justified on a harder-to-access roof or one you want to keep longer. Metal roofing becomes attractive when long service life and snow shedding matter more than upfront cost, especially on rural homes or owners planning to stay put for decades. Flat membrane systems are the correct choice only where the roof is truly low-slope. In Ontario, some insurers may discount impact-resistant or high-wind-rated systems, but discounts vary by carrier and are not guaranteed, so it is worth asking before you buy. In the Kingston–Pembroke market, the best choice is usually the one that pairs the right material with proper ventilation, flashing and ice protection.

How to choose a roofing contractor in Renfrew
Start by verifying the basics before you compare price. Ask for the contractor’s legal business name, then check online for their Ontario business registration and local reputation. Request a certificate of liability insurance and call the insurer to confirm the policy is current and the limits are adequate. If workers are covered by WSIB, ask for a current clearance letter and verify it through WSIB’s online clearance system. If the company uses subcontractors, confirm they are also insured and covered. After that, get at least 2 or 3 itemised written quotes so you can compare labour, materials, underlayment, ice-and-water shield, flashing, ventilation and disposal line by line instead of relying on a lump sum. Make sure the quote states whether permit fees are included, who is responsible for pulling the permit if one is required, and whether dump fees and magnet clean-up are included. Warranty details matter too: ask for the workmanship warranty length, the product warranty from the manufacturer and whether it transfers to the next owner. For payment, never hand over more than 10–15% upfront, and keep the rest tied to completion and final inspection. Get the start date and completion estimate in writing, because weather delays are common in Ontario and you want the timeline documented.
- Check the contractor’s Ontario business registration.
- Confirm liability insurance is active and ask for the certificate.
- Verify WSIB coverage with a current clearance letter.
- Ask who will actually do the work: employees or subcontractors.
- Get 2–3 itemised written quotes, not just a lump sum.
- Make sure the quote lists labour, materials, underlayment and flashing separately.
- Confirm ice-and-water shield coverage for eaves, valleys and penetrations.
- Ask whether disposal, cleanup and magnet sweep are included.
- Confirm who pulls the permit if one is needed.
- Read the workmanship warranty and product warranty carefully.
- Ask if the warranty is transferable to a future buyer.
- Get the start date, duration and payment schedule in writing.
Red flags in Renfrew include a contractor who will not show insurance or WSIB documents, refuses to itemise the quote, pushes for a cash-only deposit, says permits are “never needed,” or quotes far below the usual $6,500 – $15,000 range without explaining what is excluded.
Frequently asked questions — roofing in Renfrew
How much does a new roof cost in Renfrew?
For most Renfrew homeowners, a new asphalt roof usually lands somewhere between $6,500 – $15,000, depending on size, pitch, tear-off layers and flashing work. Older homes in Ontario often cost more because once the shingles come off, contractors may find soft decking, poor ventilation or worn chimney flashing that needs attention. In Renfrew, that is common on houses built before 1981, especially if the roof has already been patched a few times. Metal roofing is a different budget entirely and often starts near $18,000 – $40,000, but it can make sense if you plan to stay in the home long-term. The cheapest quote is not always the best value if it leaves out disposal, ice-and-water shield or proper flashing.
How long does a roof replacement take in Renfrew?
Most straightforward roof replacements in Renfrew take 1 to 3 days, but that depends on the roof size, weather and how much tear-off is involved. A small bungalow with a simple pitch may be done quickly, while a larger home with chimneys, skylights or two layers of old shingles can take longer. In Ontario, weather windows matter a lot because rain, frost and wind can interrupt the job. If decking repairs are needed, expect extra time. Metal roofs and flat membrane systems usually take longer than basic asphalt jobs, especially if there is custom flashing or structural work involved. A contractor should give you a start date and completion estimate in writing so you know whether the crew is scheduling around peak-season demand or waiting on materials.
Asphalt shingles vs metal roofing — which is better for Renfrew's climate?
For many Renfrew homes, architectural asphalt shingles are the best balance of cost and performance. They handle Ontario’s freeze-thaw cycles reasonably well when ventilation and ice protection are installed properly, and they usually fall within the $7,500 – $15,000 band. Metal roofing is stronger for snow shedding, long service life and low maintenance, but it usually costs much more, often $18,000 – $40,000. If you are staying in the house for decades, metal can be worth it, especially on rural or steep roofs where snow slides cleanly. If you want a practical upgrade without the big jump in cost, laminated asphalt is often the sweet spot. For most Renfrew homeowners, the right answer depends on budget, roof complexity and how long you expect to keep the property.
How long should a roof last in Renfrew?
A typical asphalt roof in Renfrew should last about 15 to 25 years, though poor ventilation, heavy ice loading and weak flashing can shorten that. Architectural shingles often do better, with a realistic life of 20 to 30 years when installed well. Metal roofs can last 40 years or more, which is why some Ontario homeowners consider them a long-term investment. Older homes in Renfrew may age roofs faster if attic ventilation is poor or if past repairs covered up underlying issues. If you are seeing curling shingles, repeated leak spots, missing granules or ice-dam staining, the roof may be near the end even if it is not yet leaking into the house. Regular inspection after major storms and every spring helps extend roof life.
Do I need a permit to replace my roof in Ontario?
In Ontario, a simple like-for-like roof replacement usually does not require a building permit, so a homeowner in Renfrew can often replace shingles on the existing roof without filing permit paperwork. However, a permit may be required if the work involves structural deck repairs, changes to the roof shape, converting a pitched roof to flat, or other alterations to the building structure. If you are adding major framing, replacing damaged structural members or changing drainage details, that is no longer a basic re-roof. Before work begins, ask your contractor whether a permit is needed and who will pull it. That should be included in the written quote, along with disposal and inspection responsibilities if applicable.
What are the signs I need a new roof?
The most common signs in Renfrew are curling or cracked shingles, missing shingles after wind, repeated leaks around chimneys or valleys, and water stains in the attic. You should also watch for granule loss, soft spots in the roof deck, sagging sections and ice-dam damage near the eaves after winter. On older Ontario homes, a roof can look okay from the ground but still be near the end of its service life if the attic is poorly ventilated or the shingles are brittle. If your roof is already 20-plus years old and repairs are becoming frequent, replacement may be more economical than patching. A small repair might still cost only $350 – $2,500, but recurring leaks often mean the whole system is failing. A local roofer should inspect both the outside and attic before advising repair or replacement.
