Question 1

How much does a roof replacement cost in Oshawa and Durham Region?

Accepted Answer

Most asphalt shingle replacements on a typical Durham Region two-storey home land between $8,500 and $16,000 including tear-off, ice-and-water shield, synthetic underlayment, new flashings, vents and disposal. Bungalows with simple gables come in lower; steep, cut-up roofs with multiple valleys, skylights and dormers run higher. Metal roofing generally runs two to three times the asphalt price. Get the quote in writing with line items — square footage, layers removed, underlayment type and vent count. Bids that only show one number hide the differences.

Question 2

Why do roofing quotes vary so much for the same house?

Accepted Answer

Because contractors are rarely quoting the same job. The big swing factors are how much ice-and-water shield is used, whether the plywood deck is priced for replacement, whether all flashings and vents are new or reused, disposal fees, warranty length, and whether WSIB and liability insurance are actually being carried. A low bid usually means one of those items was quietly removed. Compare three quotes line by line rather than by bottom line, and ask each contractor for a current WSIB clearance certificate.

Question 3

Do you charge for a roof estimate or inspection?

Accepted Answer

No. Inspections and written estimates are free across our service area — roughly 150 km of Oshawa, including Whitby, Ajax, Pickering, Bowmanville, Courtice, Scarborough, Markham, Toronto, Peterborough and Lindsay. We climb the roof where it is safe to do so, photograph everything we find, and hand you a fixed written price.

Question 4

Is there financing available for a new roof?

Accepted Answer

Yes. We can walk you through financing options that spread a replacement over monthly payments, which is common when a roof fails earlier than a household budgeted for. We will also tell you honestly if a targeted repair buys you two or three more seasons instead. If the roof still has real life left, spend the money on ventilation and flashing repairs first — it is a fraction of the cost and it extends what you already own.

Question 5

Does a new roof add value when selling a home in Ontario?

Accepted Answer

A new roof rarely returns its full cost as a price bump, but an old roof absolutely costs you — buyers and home inspectors flag it, and lenders and insurers sometimes require replacement before closing. A documented, warrantied roof removes the biggest negotiating lever a buyer has.

Question 6

Is HST included in your roofing quotes?

Accepted Answer

Our proposals show the subtotal and 13% Ontario HST as separate line items so you always know the pre-tax scope and the final number. Any deposit and payment schedule is written on the same page.

Question 7

Does home insurance cover hail or wind damage to my roof in Ontario?

Accepted Answer

Most Ontario homeowner policies cover sudden storm damage from hail and wind, subject to your deductible. What they do not cover is wear, age, poor maintenance or long-running leaks. The distinction matters: an adjuster is deciding whether the damage was caused by a specific weather event or by twenty years of sun and freeze-thaw. Photograph the damage and note the storm date before anything is touched or tarped. That timestamped evidence is what gets claims approved.

Question 8

How long do I have to file a storm damage claim?

Accepted Answer

Policies typically expect prompt notice — often interpreted as within days to a few weeks of discovering damage, and many insurers apply a hard limit of one to two years from the loss date. Waiting also weakens the claim, because the insurer can argue the damage worsened from neglect. Call your insurer the same week you notice damage, even if you have not decided whether to proceed.

Question 9

Will you meet my insurance adjuster on the roof?

Accepted Answer

Yes, and we recommend it. We climb the roof with the adjuster, walk through our photo report, and make sure everything that was damaged is in the approved scope — not just the obvious slope. Claims are routinely underscoped when nobody from the contractor side is present.

Question 10

What does hail damage on a shingle actually look like?

Accepted Answer

Look for round bruises where the granules have been knocked off and the black asphalt mat shows through, soft spots that feel like a bruised apple, and matching dents on soft metals — vents, gutters, aluminum fascia and the top of your air conditioner. Random scattered marks are hail; straight lines of wear are usually foot traffic or manufacturing pattern. Check the AC condenser and downspouts from the ground first. If those are dimpled, the roof almost certainly took a hit too.

Question 11

My shingles blew off in a windstorm. Is that an emergency?

Accepted Answer

It is urgent whenever the underlayment or bare deck is exposed, because the next rainfall goes straight into the attic. Emergency tarping stabilizes the roof so you are not accumulating interior damage while a permanent repair is scheduled. Call for tarping the same day; document the exposed area with photos before the tarp goes on.

Question 12

Should I sign with a storm-chasing company that knocks on my door?

Accepted Answer

Be careful. After a major hail event, out-of-province crews canvass neighbourhoods, ask for a signed authorization on the spot, and disappear once the cheque clears — leaving no one local to honour a workmanship warranty. Ontario requires contractors to carry WSIB coverage and liability insurance. Never sign anything at the door. Verify a local address, a WSIB clearance certificate and a written workmanship warranty first.

Question 13

How long does an asphalt shingle roof last in Ontario winters?

Accepted Answer

Architectural asphalt shingles realistically deliver 20 to 28 years in our freeze-thaw climate, versus the 30 to 50 years printed on the wrapper. Ventilation is the deciding factor: an under-ventilated attic cooks shingles from below and can cut a decade off the roof. Ask any contractor to calculate intake versus exhaust ventilation. If they cannot, they are guessing on the part that determines lifespan.

Question 14

Metal roof vs asphalt shingles — which is better in Ontario?

Accepted Answer

Metal lasts 40 to 60 years, sheds snow well, resists wind, and costs roughly two to three times asphalt up front. Asphalt is cheaper, faster to install, easier to repair section by section, and simpler to match. If you plan to be in the house for more than fifteen years, metal usually wins on cost per year; if not, asphalt is the smarter allocation.

Question 15

What is ice-and-water shield and how much do I need?

Accepted Answer

It is a self-adhering waterproof membrane installed at the eaves, in valleys and around penetrations. The Ontario Building Code requires eave protection extending from the edge to at least 900 mm inside the inner face of the exterior wall — meaning on many houses a single course is not enough. On low-slope sections and north-facing slopes prone to ice, ask for a second course. The upgrade is inexpensive compared to an ice-dam repair.

Question 16

Can new shingles be installed over the old ones?

Accepted Answer

Physically yes, on a single existing layer, and it saves on disposal. We rarely recommend it: you cannot inspect the deck for rot, the new shingles telegraph every old imperfection, the assembly runs hotter and fails earlier, and some manufacturer warranties are voided. Do the full tear-off. The savings on a layover typically evaporate within a decade.

Question 17

What roofing warranty should I expect?

Accepted Answer

There are two, and they are different. The manufacturer warranty covers the shingle itself — typically limited lifetime with a prorated schedule. The workmanship warranty covers our installation, which is where the overwhelming majority of real problems originate. Ask for both in writing.

Question 18

Are cool or reflective shingles worth it here?

Accepted Answer

In Southern Ontario the summer cooling benefit is modest compared to the U.S. sunbelt, and darker roofs shed snow marginally faster. Proper attic ventilation and insulation buy you far more comfort and energy savings than shingle colour does.

Question 19

How long does a roof replacement take?

Accepted Answer

A standard detached home is one to two days: tear-off in the morning, dry-in the same day, finish and clean up on day two. Large, complex or steep roofs and metal installs run three to five days. We do not leave a roof open overnight.

Question 20

Do I need a permit to replace a roof in Durham Region?

Accepted Answer

Straight replacement of roof covering on a house generally does not require a building permit in Ontario municipalities such as Oshawa, Whitby, Ajax and Clarington. A permit is required when structural work is involved — changing the roof line, replacing trusses or rafters, or altering the structure. We confirm with your municipality before starting anything structural.

Question 21

What time of year is best to replace a roof in Ontario?

Accepted Answer

Late spring through October is ideal because shingles need warmth to seal properly. Winter installs are possible with hand-sealing and careful handling, and are sometimes necessary after a failure — but if the roof can wait, book for shoulder season when schedules are open and pricing is more flexible. Booking in late winter for a spring install usually gets you the best crew availability of the year.

Question 22

What do I need to do to prepare for install day?

Accepted Answer

Move vehicles off the driveway, take down fragile items hanging on interior walls, and give us access to a power outlet. We tarp landscaping and siding, set up dumpster protection, keep the driveway clear for your access where possible, and run a magnet sweep across the property before we leave.

Question 23

Do you clean up nails and debris?

Accepted Answer

Yes — full magnetic sweeps of the driveway, lawn and garden beds at the end of each day and again at final walkthrough, plus a photo report of the finished roof handed over with your warranty paperwork. If you find anything afterward, call us and we come back.

Question 24

How often should I have my roof inspected?

Accepted Answer

Once a year, plus after any severe hail or wind event. Annual inspection catches lifted flashing, failed pipe boots and clogged valleys while they are still a $300 repair rather than a ceiling replacement. Book the inspection each fall, before freeze-up locks in whatever problems the roof already has.

Question 25

What causes ice dams and how do I stop them?

Accepted Answer

Heat escaping from the living space warms the roof deck, melts the snowpack, and the water refreezes at the cold eave until it backs up under the shingles. The fix is almost never on the roof surface — it is air sealing, attic insulation and balanced intake-to-exhaust ventilation, backed by ice-and-water shield at the eaves. Never chip ice off with a hammer or axe. You will destroy the shingles and turn a seasonal nuisance into a replacement.

Question 26

Why is my attic damp or growing mould?

Accepted Answer

Usually a ventilation and moisture problem rather than a leak: bathroom or dryer fans venting into the attic instead of outdoors, blocked soffit intake buried under insulation, or too little exhaust at the ridge. Warm, wet indoor air condenses on the cold underside of the sheathing all winter.

Question 27

How do I know whether to repair or replace my roof?

Accepted Answer

Repair when the damage is localized, the shingles are still flexible with granules intact, and the roof is under roughly 15 years old. Replace when you see widespread curling and bald patches, multiple leaks in different areas, sagging, or repeated repairs stacking up on a roof past 20 years. We tell you either way. If your roof still has life in it, we will quote the repair and put the replacement conversation off for a few years.

Question 28

Do gutters and eavestroughs really affect my roof?

Accepted Answer

Yes. Overflowing or undersized eavestroughs push water back into the fascia and soffit, rot the roof edge, and in winter they seed ice dams. Downspouts that dump beside the house also send water into the foundation — a roof problem that shows up in the basement.

Question 29

Which flat roof system is best — TPO, EPDM or modified bitumen?

Accepted Answer

TPO is a white heat-welded membrane, reflective and popular on retail and warehouses. EPDM is black rubber, exceptionally durable and simple to repair, but absorbs heat. Modified bitumen is a torch or self-adhered multi-ply system that handles heavy foot traffic and complex penetrations well. The right choice depends on rooftop traffic, HVAC layout, insulation strategy and budget horizon. Match the system to how the roof gets used. Buildings with heavy service traffic around units almost always do better on modified bitumen or a reinforced walkway pad system.

Question 30

How long does a commercial flat roof last?

Accepted Answer

Roughly 20 to 30 years for TPO and EPDM and 20 to 25 for modified bitumen, when they are inspected and maintained. Neglected flat roofs fail far earlier, almost always at seams, drains and penetrations rather than in the field of the membrane.

Question 31

Do you offer maintenance programs for commercial buildings?

Accepted Answer

Yes. Scheduled semi-annual inspections with written condition reports, drain and seam servicing, minor repairs handled before they escalate, and a multi-year capital plan so ownership can budget replacement instead of reacting to an emergency. For multi-building portfolios, a maintenance program is nearly always cheaper than the emergency repairs it prevents.

Question 32

Can you work outside business hours to avoid disrupting tenants?

Accepted Answer

Yes. Retail plazas, medical offices and restaurants routinely need evening or weekend work windows, staged sections, and odour and noise management. We plan phasing and tenant notification into the proposal.
