Roof repairs fix specific faults in a pitched or flat roof, such as slipped or cracked tiles, loose ridges, failed flashing, leaking valleys or chimney defects, to stop water getting in without replacing the whole roof.
Across Gwynedd, people look into roof repairs to replace something worn out, to make the house work better for them, or to get it ready for a sale. We cover Bangor, Gwynedd, Llandudno, Holyhead and Caernarfon and the smaller towns around them, working to the rules that apply in Wales. Expect a guide of £300–£1,400, VAT included, in Wales, and every quote follows a free visit.

Homes in Gwynedd
Slate defines much of Gwynedd, from quarrying villages such as Bethesda and Blaenau Ffestiniog with their stone terraces to slate roofs across the county. Bangor and Caernarfon have Victorian and Georgian streets, Anglesey has stone cottages and bungalows, and resorts such as Pwllheli and Barmouth have Victorian terraces and newer bungalows.
Stone and slate homes need breathable lime render and pointing, and slate roofs often need careful repair rather than replacement. Terraces suit loft conversions, and bungalows commonly take extensions and window upgrades.
Eryri (Snowdonia) is among the wettest areas in the UK, and exposed coasts take strong wind and salt, so render and roof details need to be robust.
Do you need permission in Gwynedd?
The notes below cover Wales, which is where Gwynedd sits. Rules change and every property is different, so we speak to the council before pricing your job.
Re-roofing with similar materials does not usually need planning permission in Wales, except on listed buildings or where a conservation area restricts materials.
Building Regulations in Wales apply to major re-roofing, including insulation upgrades. Bats are protected across the UK; if they roost under roof tiles, soffits or fascias, work stops and a licensed ecologist advises before it restarts.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
How does the job run?
We look at the job
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for roof repairs, and photograph or measure anything the quote needs to reflect.
Quote in writing
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for roof repairs.
Dates and permissions
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for roof repairs are in place before the first day on site.
Build and hand over
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.

Questions about roof repairs in Gwynedd
Will my home insurance pay for the repair?
Home insurance policies often cover sudden storm damage but usually exclude wear and tear or gradual deterioration. If you think the damage is storm-related, contact your insurer before repairs, apart from urgent temporary work, and take photos. We can provide a written report and photographs describing the damage and cause to help with your claim. The insurer decides what is covered.
How can I spot roof problems early?
Spotting roof problems early saves money. Look from the ground after storms for slipped or missing tiles, cracked ridge mortar or debris in gutters. In the loft, check for daylight, damp patches, stained timbers or wet insulation. Inside, watch for ceiling stains and peeling paint near outside walls. Clearing gutters each autumn prevents overflow damage.
How long will roof repairs take?
On a typical home, allow Half a day to 3 days for most repairs. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
What is dry-fix ridge and is it better than mortar?
Dry-fix ridge systems use screws, clips and weather seals instead of mortar to hold ridge and hip tiles in place. They avoid the cracking and loosening that mortar suffers over time, need less upkeep and are now common on new roofs. Mortar-bedded ridges suit some period or conservation-area roofs. We recommend the method that suits your roof and its location.
