Completed Jersey roof refurbishment with Spanish slate hipped roof and single-ply flat roof

Roof Repairs in Jersey

Roof repairs in Jersey are what we're called out for most often: missing ridges, slipped slates and broken tiles, along with the leaks that follow them.

We assess the roof and determine the best approach to safely and securely undertake the work, with materials sourced to blend seamlessly with the existing covering where possible.

What the job involves

Every repair starts with finding the actual source of the problem, which isn't always where the leak shows up inside the property. Water can travel along rafters or underlay before dripping through a ceiling some distance from the fault, so we trace it back to the roof itself rather than patching the visible symptom.

Once we've identified the cause, whether that's a missing ridge, a slipped or cracked slate, a broken tile, a failed lead flashing or a split in a flat roof membrane, we agree the safest and most secure way to carry out the repair, including how we access it. Small repairs may be reached from a tower or ladder; anything more extensive is scaffolded properly rather than rushed.

Materials are sourced to match the existing roof as closely as possible so the repair blends in. Where a matching slate or tile has to be ordered in, we'll fit a temporary cover on the same visit to keep water out until it arrives.

Repairs we carry out

  • Missing, loose or cracked ridge and hip tiles, re-bedded or converted to a dry system
  • Slipped, cracked and missing slates, including widespread nail sickness
  • Broken clay, concrete and fibre cement tiles matched to the existing covering
  • Verge and abutment repairs where mortar has failed
  • Chimney flashing and valley lead repairs
  • Flat roof patch repairs to single-ply and liquid membranes
  • Storm damage assessment and made-safe visits
  • Rooflight and Velux flashing leaks

Common problems we fix

  • Leaks following heavy rain or Atlantic storms
  • Slipped, cracked or missing slates and tiles after high winds
  • Storm damage to ridge tiles, hips and verges
  • Chimney flashing leaks where lead has pulled away from the stack
  • Flat roof leaks around upstands, pipe penetrations and edge trims
  • Nail sickness causing widespread slipped slates on older roofs
  • Blocked or damaged guttering causing water to back up under roof edges
  • Corroded fixings on exposed coastal roofs weakened by salt air over time

Materials and standards we use

Repairs are carried out using materials matched to the existing roof wherever possible, whether natural Spanish or Welsh slate, fibre cement slate, clay pantiles, plain tiles or concrete tiles. Lead repairs follow Rolled Lead Sheet Association guidelines and use code 4, 5 or 6 milled lead as the detail requires.

All repair work is completed to a high standard for the fixing and lapping of slates and tiles. We take the same care over a small repair as a full reroof, since a poorly fixed patch tends to fail again quickly in Jersey's exposed coastal conditions.

How much does it cost in Jersey

Repair costs vary with the extent of the damage and how accessible the affected area is. A single slipped slate on a low-pitched roof near ground level is a quick job, while storm damage spread across a large or steeply pitched roof, or a repair needing scaffolding rather than a tower, takes longer and costs more.

The condition of the surrounding roof also plays a part. Sometimes what looks like a single fault turns out to involve wider nail sickness or perished underlay nearby, which we'll flag before carrying out work beyond the original call-out. Material availability and freight lead time for specific slate or tile matches can factor in too.

We provide a free, written estimate for repair work just as we do for larger projects, so you know the cost before we proceed.

Frequently asked questions

How quickly can you come out for a leak?
We aim for a same week response for repair call-outs during our normal working hours, Monday to Friday 08:00 to 17:00. Call 01534 766100 and we'll assess urgency and get someone out to inspect the roof and stop further water ingress where needed.
Will the repair match the rest of my roof?
That's the aim. We source slates and tiles to blend seamlessly with the existing covering wherever possible, and where an exact match isn't available we show you the closest option before fitting it.
Will you fit a temporary fix before the full repair?
Yes, where a full repair can't be completed immediately, for example if matching materials need ordering, we'll fit a temporary cover to stop water getting in and agree the permanent fix for as soon as materials and access allow.
Can you tell if storm damage is covered by insurance?
We're not insurance assessors, but we can provide a written report and photos of the damage that you can pass to your insurer, and we're happy to discuss what we found on the roof if your insurance company needs further detail.
