White gable roof peaks with dark shingled ridges

Repairs, replacements and the things that cause both

The full list

4:12–9:12

01 Full roof replacement — asphalt shingle

Tear off to the deck, inspect every sheet of plywood, rebuild the assembly properly, haul everything away. Most Markham semis and two-storeys are a one to two day job.

Diagnosis first

02 Roof repair & leak diagnosis

A stain on the ceiling is almost never directly under the hole. We find where water actually enters — usually a valley, a flashing, or a nail that backed out — before anyone quotes you a new roof.

Same-day tarp

03 Emergency storm & wind damage

Shingles gone after a windstorm, a branch through the deck, water coming in tonight. We tarp it, stop the water, then quote the permanent repair in daylight.

Under 2:12

04 Flat & low-slope roofing

Additions, garages, and porch roofs under 2:12 can't take shingles. These need a membrane, proper drainage, and correctly detailed edges and curbs.

5 inch and 6 inch

05 Eavestrough, soffit, fascia

Water has to get off the roof and away from the foundation. Undersized troughs, rotted fascia, and blocked soffit vents cause damage that gets blamed on the roof.

Step + counter

06 Skylight & chimney flashing

Most leaks that look like roof failures are failed flashing details. Skylights and chimneys need step flashing and counter flashing, not a bead of caulk.

Intake + exhaust

07 Attic ventilation & insulation

A hot attic in July cooks shingles from underneath and shortens their life. A warm attic in January melts snow, which refreezes at the eave and pushes water back under the roof.

≥ 900 mm

08 Ice dam prevention & removal

If you get an ice ridge along the eaves every winter, the roof is losing heat. We remove the dam safely with steam, then fix the cause — ventilation, insulation, and shield coverage.

Deck to ridge cap · seven layers · 4:12 typical Markham pitch

What is actually on your roof

A roof is not shingles. Shingles are the last layer of seven, and they are the only one you can see from the ground. Every corner a cheap quote cuts is in the six layers underneath. Here is the whole assembly, in order, with the numbers that matter.

01 Roof deck

3/8 to 7/16 inch plywood or OSB

We pull the old roof down to bare wood and walk the whole deck. Sheets that flex underfoot, are delaminating, or are stained black from a long-running leak get replaced. You cannot tell any of this from the driveway, and it is the reason we quote deck repair as a possibility rather than a certainty.

02 Ice-and-water shield

Minimum 900 mm up from the eave edge

This is a self-sealing membrane that grips the deck and seals around nails. Ontario requires it to run at least 900 mm up the slope from the eave — measured from the outside face of the wall, not from the edge of the fascia. On low-slope roofs and in valleys it needs to go further. This is the single most common place a cheap quote saves money, because once the shingles are on, nobody can see how far up it went. We photograph ours before the underlayment goes on.

03 Synthetic underlayment

Over the full remaining field

A tear-resistant sheet across everything above the shield. It is the roof’s backup while the shingles are being installed and after a shingle is lost in a windstorm. Felt paper is the older, cheaper option and it wrinkles and tears.

04 Drip edge & starter strip

Metal at eaves and rakes

Drip edge is bent metal that carries water off the deck and into the trough instead of back behind the fascia. Starter strip is a purpose-made first course that gives the field shingles something sealed to bond to at the edge. Cutting up regular shingles to fake a starter is a shortcut you will see on a lot of roofs.

05 Shingles

4 to 6 nails per shingle, in the nail line

The visible layer. Nail placement matters more than brand: nails driven high, low, crooked, or overdriven all void the manufacturer’s wind rating, and that is exactly what the warranty inspector checks after a wind claim.

06 Attic ventilation

Intake at the soffit, exhaust at the ridge

Air has to enter low and leave high. Exhaust vents without matching soffit intake do nothing but pull conditioned air out of your house. Get this wrong and the attic runs hot in summer, cooking the shingles from below, and warm in winter, melting snow that refreezes at the cold eave and becomes an ice dam.

07 Ridge cap

Purpose-made cap over the vent

The cap closes the ridge and covers the vent while still letting air out. It takes the most weather exposure of anything on the roof and it is the last thing installed, which is why a rushed crew tends to rush it.
