Roof repairs in Swindon

A damp patch tells you water has reached the ceiling. It rarely tells you where the water came in. On a pitched roof, rain that gets past the slates or tiles lands on the underlay or the battens and runs downhill, sideways along a rafter or across the top of the ceiling until it finds a low point. That is why repairs aimed at the tile directly above a stain so often fail.

Q1.1Where does rain most often find its way into a pitched roof?

Junctions are where most leaks start. Lead flashings where a roof meets a wall or a chimney crack with age or lift when the mortar holding them perishes. Valleys, the channels where two slopes meet, carry the most water on the roof and fill with leaves and moss. Ridges and hips bedded on old mortar loosen in high winds. Roof windows and soil pipes need a seal properly formed at installation, and a tired one lets water track in at the edge.

Q1.2Could the wet loft be condensation rather than a leak?

Not every wet loft is a roof leak. Warm, damp air from the house condenses on the cold underside of the roof, especially where insulation has been added without ventilation, and drips back onto the ceiling on cold mornings. The tell-tale signs are droplets spread evenly across the underlay or on nail tips, and damp that appears in dry, frosty weather rather than after rain. The fix is ventilation, not new tiles, and our answer on telling a leak from condensation explains the checks.

Q1.3Can slates, tiles or underlay be the cause?

The covering itself fails too, just less often than people expect. Slates delaminate or slip when their nails rust through, concrete tiles crack, and on older Swindon terraces with no underlay at all, a single slipped slate can let rain straight onto the ceiling below. Where the underlay has turned brittle, driving rain that would normally drain away gets through.

Q1.4Can blocked guttering or a rotten fascia let water in?

Yes, and it is easy to blame the tiles instead. A gutter packed with leaves or sagging off its brackets overflows at the eaves, tracks behind the fascia board, soaks the soffit and stains the wall or the bedroom ceiling below. Timber fascias that have softened lose their grip on the gutter, which makes it worse. The repair may be a cleared outlet and a reset bracket, or new uPVC roofline where the boards have gone. Our gutters, soffits and fascias page covers that work.

Q1.5What if a storm caused the damage?

Once the roof is weathertight, storm damage becomes a planned repair like any other: matched tiles or slates, a refixed ridge, new lead where a flashing lifted. If you are claiming on home insurance, tell your insurer early, keep photographs and receipts, and expect questions about whether the roof was sound beforehand. The Financial Ombudsman weighs the date, the kind of damage and the roof's prior condition, so dated photographs from our visit can help. Whether a claim pays is the insurer's decision.

Q1.6How do you trace where a leak starts?

We start in the loft with a torch, looking for wet timber, stained underlay and daylight. Then we go up and check the likely entry points above and uphill of the damp. We photograph what we find and show you, so you can see the cause rather than take our word for it. Our guide to finding a roof leak sets out the method, and the most common causes of roof leaks are covered one by one.

Scaffolding can be the largest part of a repair price, so it is fair to ask whether it is needed. The answer depends on the height, the length of time on the roof and how the work can be done safely, not on what is quickest for the roofer.

Q4.1When are ladders and towers enough for a repair?

A short repair on a bungalow, a porch, a flat-roofed extension or the lower slopes of a two-storey house can usually be done from a ladder tied in at the top, with a roof ladder hooked over the ridge for work on the slope. A mobile tower suits gutters, fascias and work along the eaves. These keep the cost down and avoid a scaffold standing on your drive for a week.

Ladders are only used where they can be footed or tied safely, and roof ladders are never hooked over a ridge tile that is itself loose. If the safe option is a tower, we bring one.

Q4.2When is scaffolding the safe choice for a repair?

Chimney stacks are the classic case: a roofer needs a stable platform at ridge height to rebuild pointing or flaunching and dress new lead. Valleys on three-storey houses, long runs of ridge and any job that will take more than a day or two at height are better done from a scaffold. Terraces with no side access sometimes need a scaffold over the front path or a scaffold licence from the council.

Scaffolders work to their own timetable, so a job that needs a scaffold usually takes longer to arrange than one we can reach from a ladder. For a leak that cannot wait, we make the roof safe from whatever access is safe on the day, then schedule the scaffold for the permanent repair. On terraces we also think about the neighbours: a scaffold across a shared front path needs their agreement, and a scaffold on the pavement needs a licence from the council.

Q4.3Is working without scaffolding legal?

The rules do not say scaffolding is required for every roof job. The expectation is that work at height is planned in advance and carried out safely with suitable equipment. Our answer on roof work without scaffolding explains how that plays out on domestic roofs. If we need a scaffold, the quote says so and tells you why.
