Roof Repair & Maintenance

Flashing failures are the most common by a wide margin. Anywhere the roof plane meets something else — a chimney, a wall, a dormer, a skylight — the waterproofing depends on metal, not on shingles. When that metal is old, bent, reused from a previous roof, or was sealed with caulk instead of being formed and let into the masonry, it leaks. Repairing it properly means new step flashing, new counter-flashing let into the mortar joint, and shingles woven back in correctly.

Pipe boots are second. The rubber collar around a plumbing stack has a shorter life than the shingles around it — high-altitude UV cracks it in ten to fifteen years — and once it splits, water runs straight down the pipe into the ceiling below. It is a cheap, fast, high-value repair and one we recommend proactively on any roof past a decade.

Valleys are third. A valley concentrates the runoff from two roof planes into one channel, so it carries more water than anything else on the roof and is the first place a shortcut shows. Valleys that were closed-cut without proper lining, or where the metal has corroded through, need re-flashing rather than patching.

Then wind damage, which in this region means chinook damage: lifted, creased or missing shingles, usually concentrated at rakes, ridges and the first courses above the eave. Creased shingles are worth noting because they often look intact from the ground — the fibreglass mat has broken along the fold and it will fail there.

And finally ice-dam damage: water forced back up under the shingles at the eave, rotting sheathing and staining ceilings along an exterior wall. The repair fixes the damage; the ventilation correction fixes the cause. Doing only the first guarantees a call next February.

Leak diagnosis is the part of this trade that separates people who fix problems from people who replace materials. Water is patient and it travels: it enters at a break in the envelope, runs along the underside of the sheathing or down a rafter, and drops through the ceiling at whatever the low point happens to be. The stain in your hallway may be four metres from the entry.

So we start at the top. On the roof we inspect every penetration, every flashing, every valley and the field itself, looking for the specific failures that cause leaks rather than for general wear. Nail pops, split boots, lifted step flashing, a counter-flashing that has pulled out of a mortar joint, a valley with a corroded seam.

Where we can get into the attic, that is often where the answer actually is, because the underside of the sheathing records the history: staining tells you where water has run, and following the stain uphill leads to the entry. Attic inspection also catches the causes people miss entirely — a bathroom fan venting into the insulation rather than through the roof, which produces ceiling staining that looks exactly like a roof leak and is not one.

Some leaks are not roof leaks at all, and we will tell you when yours is one. Condensation from an unbalanced attic, a failed window head flashing, a wall-cladding problem above a storey line, or a plumbing vent stack corroded inside the wall all present as ceiling stains. Replacing a roof to fix any of those is an expensive way to learn nothing.

Three questions decide it, and none of them is 'how big is the quote'.

First, how old is the roof? Under about fifteen years, a repair is usually sound because the surrounding shingles are still flexible enough to lift, work under and reseal without breaking. Past twenty, they crack when lifted, which means fixing one square metre damages the two around it.

Second, is the failure localized or systemic? One chimney, one boot, one valley, one wind-damaged elevation — that is a repair. Granule loss across the whole roof, curling on every plane, sealant strips released broadly — that is a roof telling you it is done, whether or not it has leaked yet.

Third, how long do you intend to keep the house? If a roof has three to five years left and you are selling next spring, a targeted repair is a rational decision. If you are staying fifteen years, spending on a roof with five years left is money you will spend again.

We answer those three questions in writing with photographs, and we are comfortable recommending the smaller job. It is worth saying plainly: a company whose answer to every repair call is a replacement quote is not diagnosing, it is selling.

Most roofs in this region get no maintenance at all between installation and failure, which is why so many fail early. A roof tune-up is a modest, unglamorous piece of work that reliably buys years: reseal exposed fasteners, replace cracked pipe boots before they split, re-secure lifted shingles, clear debris from valleys, check and reseat ridge cap, verify flashing at every penetration, and confirm the eavestroughs are clear and pitched so water is not backing up under the shingle edge.

The best time for it is late summer or early fall, before the first freeze. A pre-winter tune-up is the highest-value inspection of the year here, because winter is when small defects become expensive: a lifted shingle in October is a leak in January when the ice dam forms over it.

Pre-sale tune-ups are the other common case. A roof that is sound but visibly neglected costs sellers real money at the negotiating table, because a buyer's inspector will list every lifted shingle and cracked boot as a deficiency. Fixing them costs a fraction of the concession they trigger, and we can supply a written condition report for the listing.

For acreage properties, add debris management to the list. Roofs under mature trees, and outbuildings that see less attention than the house, accumulate needles and leaves in valleys where they hold moisture against the shingle indefinitely.

Some roof problems cannot wait for a scheduled slot. A tree limb through the deck, a section of shingles stripped by a chinook, or an active leak dropping water into a living room needs the water stopped now and the permanent repair scheduled after.

Emergency work is triaged ahead of planned jobs. The immediate priority is a weather-tight temporary cover — properly fastened tarping over the opening, not a sheet weighted with bricks — so that the interior stops taking damage while the permanent scope is assessed and, where insurance is involved, documented.

Documentation matters here more than people realize. Photographs taken before the temporary cover goes on are what establish the cause and extent of a sudden loss, and an insurer will ask for them. We take them as a matter of course.

After a widespread storm, be aware of what happens next in this market: out-of-province crews arrive within days, knock doors, and offer to cover deductibles or start work before an adjuster has been out. Both are things to be wary of. Ask any contractor for their Alberta business licence, proof of liability insurance and a current WCB clearance letter before signing anything. A legitimate contractor hands those over without hesitating.

Repair demand tracks the weather closely here. A single chinook event generates a wave of wind-damage calls across the west side of the city and out through Springbank, Bearspaw, Cochrane and Bragg Creek. A late-winter thaw generates ice-dam calls in older neighbourhoods with under-ventilated attics — Ranchlands, Thorncliffe, Acadia, Willow Park. And any summer hail event generates everything at once, everywhere it crossed.

We repair roofs in every Calgary quadrant, and out through Airdrie, Chestermere, Cochrane, Okotoks, High River, Langdon and Strathmore; north through Crossfield, Carstairs, Didsbury, Olds, Innisfail to Red Deer and Sylvan Lake; west to Canmore; and east to Beiseker, Three Hills and Drumheller.

For acreage properties, repair scheduling works differently. Sending a crew forty-five minutes out for a single pipe boot is inefficient for everyone, so we usually inspect the whole property at once — house, garage, shop and any outbuilding — and do all the work identified in one visit. It costs you less and it means the small problems on the buildings nobody looks at get caught before they become large ones.
