Most shingle damage is a few courses, not a roof. The wind takes a band, a branch cracks a tab, the sun bakes a seal strip until it lets go. We replace what failed, check what is next to it, and match what is already up there.
Leaking right now? Call and say so. Emergency calls are answered 8 am–5 pm weekdays, weekends by arrangement for a fee. An active leak gets a temporary measure first, then a proper repair once the roof is dry enough to do it right.
Call 250-258-8600You can see most of these from the driveway with the sun low. What you cannot see from there is the shingle next to the damaged one, which is why we go up.
The seal strip along the underside has let go. The shingle is still nailed but no longer bonded, and the next gust gets under it and the course above.
Underlayment or plywood showing. Underlayment sheds a shower, not a season, and a bare deck sheds nothing.
Straight cracks from thermal movement on an ageing mat, or a break where a branch or a boot landed. One cracked tab is a leak path straight to the nail line below.
Corners turning up or the middle of the tab dishing. On a few shingles it is a repair; across a slope it is the shingle telling you its age.
Granules are the shingle’s UV protection. A localised bald patch under a downspout or where someone walked is repairable. Mat showing across the field is not.
A nail backing out lifts the shingle over it and leaves a hole in the one under it. Common where the deck has moved or the roof was nailed high.
Caps take the most wind and the most sun. They split along the bend and go first, leaving the ridge nail line open.
A green mat on the north slope that is thickening under the shingle edges and holding water against them. See maintenance for the prevention side.
An asphalt shingle is a fibreglass mat, asphalt, and a layer of granules to keep the sun off the asphalt. Kelowna gives it more sun than most of the country, on a south slope that can run well above air temperature all summer. The asphalt dries, the mat goes brittle, the seal strip that bonds each course to the one below bakes until it no longer bonds. Then a wind off the lake finds the one tab that has let go.
The north slope has the opposite problem. Under the pines it stays shaded and damp, needles collect in the valleys, and moss takes hold. Moss does not just sit on the surface; it grows under the shingle edges, lifts them, and holds water against the mat through every freeze-thaw cycle of the winter. Ice forming in that water pries the courses apart a little more each time.
Add the wind, which loads edges, ridges and the lake-facing slope far harder than the middle of the field, and you get the pattern we see on almost every call: a roof that is mostly fine, with one band or one slope that is not.
A lifted shingle is not a leak yet. It is the start of a sequence that ends in one, and each step along it costs more than the one before.
The seal strip has gone or the tab is broken. Underlayment is doing the work the shingle should. It sheds rain for now, and the nail line under the damage is exposed to weather.
Fix now: a few shingles, resecured or replaced
Wind gets under the loose course and peels the ones above it, because their seal strips broke when the first one lifted. A three-shingle repair is now a band across the slope, often with a vent gone too.
Fix now: a section, with underlayment
Torn underlayment lets water onto the plywood, which swells and loosens the nails around it. Inside, the ceiling under the slope stains and the insulation starts to hold water.
Fix now: section plus deck patch and drywall
Sheathing delaminates and no longer holds a nail. New shingles cannot be fastened into it, so the repair is new plywood first. By now the neighbouring courses have aged the same way and the honest answer is often the slope.
Fix now: new deck, often a re-roof
We drew the whole sequence, stage by stage, with the roof section changing as you scroll.
The cost of waitingThe bare patch is the easy part. A shingle repair that lasts is about the courses around it, the underlayment beneath it, and matching what is already on the roof.
Wind damage is routinely worse from the roof than from the ground. Every course around the visible damage gets lifted gently by hand: a shingle that stayed on but no longer bonds to the one below will go in the next blow, and it belongs in this repair, not the next one. Ridge and hip caps, edge metal and any vents in the band get the same look.
A sound shingle that has only lost its seal gets resealed with roofing cement under the tab and, where the nails have lifted, renailed and the heads sealed. A cracked, curled, bald or missing shingle comes out: the nails in it and the course above are pulled, the new shingle slides in, is fastened in the nail line, and the tab above is resealed over it.
Three-tab and architectural shingles are not interchangeable, and neither are colour blends. We match the profile and the closest current colour, and on a visible slope we show you the match before it goes on. A new shingle reads a shade darker than the sun-faded roof around it for a season or two, then weathers in. IKO is the shingle brand Premium installs and is certified for; we carry it, but we match whatever is on your roof.
Torn or stapled-through underlayment under the repair is replaced and lapped correctly, uphill over downhill, so it sheds water the way it should. If the plywood under it is swollen or soft, that gets said out loud and the section is replaced before anything is nailed into it. Fastening new shingles into a deck that cannot hold a nail is not a repair.
Ridge caps in the band are replaced and the ridge nail line resealed; any vent that lifted goes back in square and flashed into the courses. Then you get what we saw on the rest of the roof, with photographs: how the other slopes are ageing, where moss is taking hold, and roughly how long the roof has, so the next decision is planned rather than made in a wind.
A band of wind damage, a cracked tab, a bald spot under a downspout, a missing cap on a roof with years left: repairs, and good ones disappear into the slope.
Shingles curling, cracking or going bald across whole slopes, granules coming off in the gutter every rain, a deck that gives underfoot: that is the roof at the end of its life, and a repair is money spent twice. We will tell you that on the first visit rather than after the third patch. Replacements are done by Premium Roofing, same crews and same phone number. How we decide.
We do not quote a roof we have not seen. What moves the number is how many courses are involved, whether the underlayment or deck under them is damaged, how steep and high the slope is, and whether ridge caps or vents are part of it.
What you can count on: the inspection and written quote are free, pricing is flat-rate, and anything that could change the number is named before work starts, not on the invoice. If the damage turns out to be smaller than it looked from the ground, the price comes down.
Tell us what you are seeing and we will come and find out what is causing it. Estimates are free, written down, and honest about whether the roof is worth repairing.
