Lead is the most durable roofing material available — properly installed it outlasts the building. We repair and replace lead flat roofs, bay tops, dormers, valleys and flashings across Guildford using Code 4 and Code 5 milled lead sheet.
We cover all Guildford postcodes (GU1) and the surrounding area. Free written quotes, no call-out fee, 10-year workmanship guarantee.
New lead flat roofs for bay tops, dormers, extensions and porches. Code 4 lead with proper drip edges, welted seams and expansion joints specified for Surrey's climate.
Step, soaker, apron and saddle flashings around chimneys, dormers, walls and skylights. Failed flashings are the most common cause of leaks on Guildford's period housing.
Valley replacement in Code 4 or Code 5 lead. We strip failed lead or mortar valleys and install new lead to the correct specification for pitch and exposure.
Splits, lifting edges and failed joints. Many lead defects can be repaired rather than replaced if caught early — saving significant cost.
Lead is ubiquitous on Guildford's older housing stock. Conservation area constraints on tile materials in the town centre. Freeze-thaw damage to ridge mortar on elevated North Downs properties. Lead flashing failures on Victorian townhouses. The thermal cycling on Guildford properties means expansion provision is critical — we always specify the correct sheet dimensions and bay widths.
Guildford straddles the River Wey in the North Downs gap. Properties on the chalk ridge above the town face significantly more wind exposure and freeze-thaw damage than valley-floor properties.

Guildford's housing spans an unusually wide range of ages and types — from Victorian townhouses in the conservation area around Quarry Street and the High Street, through 1930s semis in Merrow and Burpham, to modern estates on the town fringe. Each era has specific roofing requirements, and properties in the conservation area have additional planning constraints on materials.
Lead roofing in Guildford is long-term work that should last 60–100 years when done correctly. The two most common sources of premature failure we encounter are sheets fixed too rigidly without expansion provision, and incorrect mortar pointing at flashing upstands. Both are installation errors that our approach prevents as standard.
Guildford's higher average property values mean the financial case for correct, quality maintenance is particularly strong. A roof maintained correctly over 20 years costs a fraction of a reactive replacement, and documented maintenance history supports premium valuations at sale.
Properties on the chalk ridge above Guildford — in Merrow, on the North Downs approach — face significantly more wind exposure than the valley floor. Ridge tile displacement after winter storms is more common on elevated Guildford properties than on comparable properties in more sheltered positions.
"Bay top had been patched with mastic twice. These guys stripped it all back and laid it properly in Code 4 lead with welted seams. Should last 60 years."
"Lead at the chimney had failed. They relaid it properly — not just pointed over the top. Dry wall for the first time in years."
"Valley had been leaking into the loft. New lead valley laid correctly with correct bay widths. No more issues through a very wet winter."
Properly installed lead sheet typically lasts 60–100+ years. The most common cause of premature failure is incorrect installation — sheets fixed without room for thermal expansion. A correctly installed lead bay top in Guildford should outlast the building.
Often yes. Small splits, lifting edges and failed joints can frequently be repaired. We assess whether repair or replacement is better long-term value and give you an honest recommendation.
Code 4 (1.8mm) is the minimum for most residential flat roofs. Code 5 is used for larger spans or more exposed positions. We always specify the appropriate code in our written quote.
Fatigue cracking occurs when lead is worked too hard by repeated thermal cycling — expanding in heat, contracting in cold. This is most common when sheets are fixed too rigidly or sized too large for the bay. Correct installation with proper expansion joints prevents it.
