Valley Repair Otterbourne

Honest advice

Do You Actually Need Valley Repair?

The valley is where two roof slopes meet and channel water away — a high-failure junction on Winchester’s period terraces. These are the warning signs. In Otterbourne specifically, elevated village exposed to wind, with the Itchen close by raising humidity in the low parts.

Damp on a ceiling directly below where two roof slopes meet
Visible cracks or splits in a lead or fibreglass valley
Debris and moss packing the valley and forcing water sideways
Rust stains from an old metal valley

When it is not the answer: A valley that is simply blocked with debris needs clearing, not rebuilding — we will clear and inspect before recommending any lead renewal. Read the full guide.

Customer Reviews

What Customers Say

★★★★★

"Had a leak for months that two other roofers had not fixed. These found it was the back gutter behind the chimney — replaced it and the ceiling dried out within two weeks."

Helen A. · St Giles Hill, Winchester

★★★★★

"Valley lead had been patched with silicone by a previous owner. They replaced the full valley in code 5 lead. No issues through the wettest winter we have had."

Rob C. · Fulflood, Winchester

★★★★★

"Diagnosed correctly from a proper survey rather than guessing. The damp was from the valley not the ridge as I had been told. Fixed properly first time."

Janet M. · Hyde, Winchester

Timescales

How Long Does It Take?

Job	Typical duration
Clear & re-seat valley	Half a day

Lead and GRP both need dry conditions; work pauses in rain with temporary cover in place. For Otterbourne properties the duration bands above are typical; your written quote gives the firm figure for your roof.

Access

Getting Safely onto Otterbourne Roofs

Valleys sit mid-slope, so a tower or scaffold is required for safe access. Scaffold is specified for: most valley rebuilds — the mid-slope position needs secure standing - always itemised in your written quote, never a hidden extra, and we arrange it.

Otterbourne mixes period cottages with modern housing; the village street is narrow but most properties have their own access. Pavement scaffold and skip permits go through Winchester City Council; allow a few working days on streets like Main Road, Kiln Lane where space is tight.

FAQ

Valley Repair Otterbourne — Questions

Lead valley re-dressing in Otterbourne: £150–£350. Full lead valley replacement: £450–£900 depending on length. Mortar valley repair: £200–£450. Free survey and written quote — call 01962 809171.

Valley failure in Otterbourne typically presents as interior damp on the ceiling 1–3 metres from the actual valley position. The water tracks horizontally after entering at the valley. If you have a damp patch that does not appear to be directly below a chimney or tile, a valley survey is the correct first step.

Otterbourne's Victorian estate and 1970s chalk housing typically has lead-lined valleys on Victorian and 1930s properties. We confirm the valley type and specification at survey.

The primary causes in Otterbourne are age (original Victorian and 1930s lead is now 80–100 years old), underweight lead from previous repairs (code 3 or 4 where code 5 is required), and silicone patch repairs that delay rather than resolve failure.

For re-dressing existing sound lead, yes — the surrounding tiles may not need lifting. For full valley replacement, the cut tiles on both sides must be lifted and relaid. We minimise disturbance to surrounding tile work on all Otterbourne valley repairs.

Code 5 (2.24mm, 25kg/m²) as the BS 6915 minimum for valley linings. We never install code 3 or 4 lead in a valley position. The cost difference is marginal; the lifespan difference is 20–30 years.

Correctly specified code 5 lead valley with correct thermal movement allowance: 60–80 years. This is the expected lifespan on a Otterbourne property where installation follows BS 6915 and Lead Sheet Association guidance.

Yes — valley outlet clearing is part of every valley survey and repair visit. Blocked valley outlets cause water to back up and overflow at the valley foot, accelerating failure. This is included in the survey, not an additional charge.

Yes — mortar valleys on post-war Otterbourne properties are often converted to lead on re-roofing. This adds £200–£400 to the valley cost but eliminates the mortar cracking that causes mortar valley failure. We include both options in re-roof quotes where mortar valleys are present.

An active valley leak causing ceiling damage should be assessed within 24–48 hours. Call 01962 809171 to book an emergency survey. We cover all of Otterbourne and can typically attend same-day or next-morning for active leaks.
