Roof Leak Diagnosis and Emergency Call-Outs

A leak almost never starts where the water lands. Water tracks along rafters, down felt laps and across ceiling joists before it drops, so the stain in the bedroom can sit two or three metres from the actual fault. The first job is to find the entry point rather than seal the nearest suspicious thing.

The survey is free, and if a small repair will do the job we say so instead of quoting a new roof.

Stage one, outside inspection

The covering is checked from ground level and from the roof itself: slipped or cracked tiles, nail fatigue in older battens, dry or missing mortar at ridge and hip, splits in flat roof laps, and flashing that has lifted out of its chase. A drone view is used where a valley, a stack or a low-level extension roof cannot be safely reached.

Stage two, inside the roof space

From the loft, daylight through the covering, wet timber, damp insulation and staining on the underside of the underlay all point back up the water's path. Condensation is checked separately, because BS 5250 ventilation faults produce damp that looks exactly like a leak and will not respond to any repair on the outside.

Stage three, the fixed price in writing

What was found, what needs doing and what it costs go into a written quote with no obligation and no charge. Emergencies go to the front of the queue, and a real person answers the phone day, night and weekend.

Slipped Tiles, Slates and Broken Roof Coverings

Slipped tiles on Guildford's Victorian terraces and Edwardian villas are usually a fixing problem rather than a tile problem. Original iron or copper nails corrode, the tile drops, and the one below takes the load until it cracks too. Replacing the tile without addressing the fixing simply buys a year.

Refixing is done to BS 5534, which governs mechanical fixing and wind uplift resistance rather than relying on mortar to hold anything down.

• Clay plain tiles: matched for size, camber and colour, twice-nailed or clipped as the exposure calculation requires.
• Natural slate: refixed with copper tingles or slate hooks where the surrounding slate is sound.
• Concrete interlocking tiles: replaced with clips at perimeters, verges and the top two courses.
• Ridge and hip: mechanically fixed dry systems, or repointed in a strong sand and cement flaunching where the character of the street calls for a mortar line.
• Battens and underlay: local sections of rotten batten and torn felt cut out and replaced under the working area.

Those specifics matter because a covering that is only bedded in mortar will lift again in the first serious gust off the downs.

Pitched and Flat Roof Repairs for Guildford Homes

Steep-pitched slate and plain-tile roofs in the older centre, and the flat roofs over rear extensions, garages and dormers on the newer estates around Merrow, Burpham and Stoughton, fail in different ways and need different repairs.

On pitched roofs the usual faults are perished underlay at the eaves, worn valleys, and mortar loss at abutments. On flat roofs the fault is normally at a detail rather than in the field: an upstand that is too shallow, a blocked outlet holding standing water, or a lap that has opened. BS 6229 sets the expectation for falls and drainage on flat roofs, and a repair that leaves water ponding against an upstand has not really been repaired.

Warm-roof upgrades, EPDM rubber, GRP fibreglass and torch-on felt are all covered as part of our flat roof work, so the repair method is chosen to suit the existing deck rather than whatever is on the van.

Repair Materials and Methods

Most repairs come down to matching what is already there and fixing it properly. On heritage-sensitive streets in the historic core, where the town council treats the historic street pattern as vital to the character of the place, that means salvaged or like-for-like tile and slate rather than a modern substitute that reads wrong from the pavement.

Leadwork follows Lead Sheet Association guidance: Code 4 for most soakers and cover flashings, Code 5 where a valley or a wider gutter lining is exposed to more movement, with bay lengths kept short enough that thermal movement does not split the sheet. Rainwater goods are sized to BS EN 12056 rather than guessed.

Where a repair sits on an asbestos-cement garage or outbuilding sheet, the material is assessed and the safe, compliant route advised under the Control of Asbestos Regulations 2012. We do not carry out licensed asbestos removal, and we will tell you plainly what needs a licensed contractor.

We soft wash and hand scrape moss, never pressure wash, because a jet lifts slate and drives water under laps. We do not sell roof coatings.

Guttering, Fascias and Roofline Repairs

A surprising share of "roof leaks" are roofline faults. Water overshooting a blocked gutter soaks the fascia, rots the batten ends and shows up inside as a wet wall head, so the roofline gets checked whenever a leak is traced to the eaves.

• Gutter realignment to a consistent fall toward the outlet, with brackets at the correct centres.
• Seamless aluminium guttering formed on site where joints have been the repeated failure point.
• Downpipe and outlet clearing, plus leaf guards on properties under mature trees.
• Rotten fascia and soffit cut out, with eaves ventilation reinstated rather than boarded over.
• Cladding and bargeboard repairs on gable ends and dormer cheeks.

Reinstating that eaves ventilation is the part most often skipped, and it is what keeps the new timber dry.

Lead Flashing, Chimneys and Valleys in Guildford

Chimneys and valleys cause more repeat leaks than the open roof ever does. On Victorian stacks in Charlotteville and Pewley Hill, the flaunching has usually cracked, the pointing has washed out of the windward face and the front apron lead has been face-fixed with mastic at some point in the past forty years.

The sequence is straightforward: rake out and repoint the stack, renew the flaunching to a proper weathering slope, then form new front apron, side soakers and back gutter in lead, chased 25mm into the joint and wedged rather than stuck. Valleys are relined in Code 5 lead or a GRP valley trough where the original open valley has worn thin at the centre.

Living with it is the part people worry about, and it is worth being plain. Most of this work happens outside, on the roof or off a scaffold or tower, so you keep the use of your rooms. Access is agreed before anyone arrives, drives and paths stay usable, old tile and mortar goes straight into a covered skip or bags rather than onto the lawn, and the site is swept at the end of each day, not just at the end of the job. Loft access, where it is needed, is booked for a stated window so you are not waiting in. If you are looking for someone to sort out roof repairs close to home in Guildford, our own roofers work across the town and the wider Wey Valley, so we are rarely far away.

Every job leaves with a 25-year written workmanship guarantee, handed over before the team goes. Scott has spent more than 36 years on Surrey roofs and still answers the phone himself. If something is not right inside those 25 years, we come back and put it right.
