The Year-10 Roof Service: What a Decade-Old Inland Cork Roof Needs

What does a decade do to an inland Cork roof?

Ten years of Cork weather does not wear a concrete tile out. It wears out the things holding the roof together. The bedding mortar under ridge and hip tiles dusts and cracks. The felt laps where the underlay meets the gutter start to curl and split. The lead apron at the chimney creeps and lifts at the edges. Gutters on mature-tree estates take on a decade of leaf load. And the first few tiles start slipping as the original nails fatigue.

None of this is visible from the front lawn until it has been failing for a year or two. That is the whole argument for a year-10 service: catch the wear items while they are still €100-€650 fixes instead of discovering them as a ceiling stain in February.

One boundary before we start. This guide covers inland Cork only: Ballincollig, Bishopstown, Wilton, Glanmire, Carrigtwohill and the city suburbs. Harbour towns age on a different clock because of the marine air, and we have written that up separately as the 8-12 year coastal replacement cycle. If your roof is in Cobh, Crosshaven or Kinsale, read that instead. Inland, there is no salt in the equation. Mortar, trees and Atlantic wind set the pace.

Which roofs are actually in the window? Any estate built from the late 2000s to the mid 2010s is crossing year 10 now. Plenty of older 1990s estates in Ballincollig and Bishopstown are in the same window on their second clock: re-roofed, re-ridged or last properly serviced around a decade ago. Count from the build date or from the last major roof work, whichever is more recent.

What are the five things we check at year 10?

Every year-10 service on an inland estate follows the same five-item list. Here is what each item is, why it fails at this age, and what the fix costs when it has failed.

1. Ridge and hip mortar. The bedding mortar under ridge tiles is the first component to go on almost every estate roof I survey. It dusts out of the joints and cracks along the bed. At year 10 you can usually lift a ridge tile by hand. A single-section re-bed is €220-€420 and takes two to three hours.
2. Felt laps at the eaves. Where the underlay laps over the fascia into the gutter, it sits in standing moisture every winter. At year 10-15 the laps curl, split and start dropping felt crumbs into the gutter. Caught early it is a localised strip-back at €420-€720, not a re-felt.
3. Lead apron lift. The lead apron at the base of a chimney creeps with thermal movement and lifts at the edges. Once wind gets under it, rain follows. A re-dress and re-fix on a chimney apron is €380-€650.
4. Gutter load. On the mature-tree roads, the Maglin and Coolroe roads in Ballincollig are the classic example, gutters at year 10 are carrying a decade of leaf mulch and sycamore seed. Loaded gutters overflow, stain the fascia and soak the eaves felt. A clear plus minor repair is €180-€500.
5. The first slipped tiles. Original fixing nails start fatiguing around this age. One slipped tile on a ladder-accessible roof is €150-€220. Three or more on one elevation is a half-day at €380-€650 and usually means the neighbours on that row will be calling soon too.

That is the whole list. If all five come back clean, you have bought certainty for €100 and you do not need to think about the roof for another two or three years.

A Ballincollig year-10 service from the job log

Thursday morning, October 2026. A 2011-built semi-D off the Maglin road in Ballincollig. Names omitted with the homeowner's permission; everything else is from the job sheet. The owner rang because a neighbour two doors down had a ridge tile come through a conservatory roof in a gale, and he realised he had never once looked at his own roof in fifteen years of ownership.

We started with the drone. €100 fixed, forty minutes, every elevation photographed plus close-ups of the ridge line, the chimney apron and the gutter interiors. Then the ladder went up for the hands-on check, because you cannot judge mortar from a photograph alone.

What we found, in the order the list always goes. Two ridge sections on the rear elevation dusting, one tile loose to the hand. The felt lap along the rear eaves curling over about four metres but not yet split. The chimney apron lifted maybe ten millimetres at the east corner. Both gutters loaded with leaf mulch, the downpipe at the gable end running slow. One slipped tile on the front elevation, felt beneath it dry.

What we did the same day, with the owner's approval on each line: both gutters cleared and the downpipe flushed, the loose ridge section re-bedded, and the slipped tile hooked back and re-nailed with copper clouts. The felt lap and the apron went out as a written quote for him to sit on. He booked the apron for the following month and decided to watch the felt through the winter. That is exactly how a service should work: the cheap items done on the spot, the bigger items in writing, no pressure.

What does a year-10 roof service cost in 2026?

The survey is €100 fixed by drone. Everything after that is priced per item from the bands below, which are our 2026 Cork job-log rates with the 13.5% VAT that applies to qualifying roofing work included (Revenue Commissioners). There is no package price, because no two decade-old roofs need the same list.

About half of the year-10 visits I run end with the survey, a gutter clear and one small repair. The other half get a written list of two or three items to schedule over the following months. Either way the work carries the same written workmanship guarantee as a big job: 20 years on anything over €100, issued as a PDF certificate you can hand to a buyer if you sell.

What if you cannot see the roof from the ground?

Most estate roofs are invisible from the lawn: rear elevations, ridge lines, chimney aprons and gutter interiors all hide at height. That is what the drone is for. Our drone roof inspection is €100 fixed anywhere in Cork, and it covers every elevation with stills you keep. You get the photo report whether or not we do a single euro of work afterwards.

The ladder still matters for one thing: mortar. A photograph shows you where mortar has cracked. A hand on the ridge tells you whether the tile lifts. Every service visit combines both, drone first, ladder second, and the photo report lists each of the five items as pass, watch, or fix.

When should you book the year-10 service?

Autumn is the right time. The roof has come through a dry summer, the gutters have not yet taken the winter leaf fall, and there is still daylight to work a full day. Getting the list done before the named-storm season means a loose ridge tile gets re-bedded in October on your schedule instead of landing in a neighbour's conservatory in January on the storm's schedule.

Book it when the roof hits year 10 from build or from the last major work. Book it when you buy a house with no roof paperwork. And book it the week a neighbour loses tiles in a gale, because estate roofs were built by the same crew with the same materials in the same months, and they fail together.

Between services, do the twice-yearly ground check yourself: binoculars on the ridge line, a look at the gutters from the lawn, five minutes in the attic with the light off checking for daylight. Anything that looks off goes on the list for the next visit. If you would rather hand the whole cycle over, that is what our roof maintenance service across Cork is built for: scheduled visits, photo reports, and fixed prices agreed before anyone climbs.
