Lead flashing is one of the most critical weatherproofing elements on any roof. It seals junctions between the roof covering and walls, chimneys, dormers, and other penetrations where water would otherwise find a way in. Across Henley-on-Thames's Georgian townhouses, Victorian villas, listed properties in the conservation area, and modern riverside developments, correctly installed leadwork is essential for keeping properties dry. Poor leadwork is one of the leading causes of roof leaks we encounter in the RG9 postcode area.

Why Leadwork Matters for Henley-on-Thames Properties

River mist and valley humidity accelerate deterioration, and the Thames valley microclimate creates persistent dampness that erodes mortar and promotes biological growth on roofing materials. Lead flashings bear the brunt of these conditions, expanding and contracting with temperature changes, enduring constant rain exposure, and resisting wind-driven water penetration. In Henley-on-Thames, properties in exposed positions across Friday Street and Fawley need leadwork that is correctly specified and expertly installed.

Properly installed code 4 or code 5 lead flashing will last 60-100 years. Poor-quality leadwork, inappropriate substitutes, and bodged repairs typically fail within 5-10 years. We regularly see Henley-on-Thames properties where previous contractors have used lead substitute tapes or mastic sealants — all of which deteriorate far sooner than correctly dressed lead.

Common Flashing Problems in Henley-on-Thames Homes

The most common flashing failure we see in Henley-on-Thames is cracking caused by thermal fatigue. Lead expands and contracts with temperature changes, and over decades this causes fatigue cracks. Properties in Northfield End and Rotherfield Greys with south-facing chimney flashings are particularly affected, as solar heating creates the greatest temperature differential.

Another frequent issue in Henley-on-Thames is flashings that have been poorly dressed or stepped. We often find flashings in Nettlebed and Highmoor that have pulled away from the brickwork because they were fixed with mastic alone rather than properly chased into the mortar course.

Our Leadwork Process in Henley-on-Thames

Every leadwork project in Henley-on-Thames begins with a careful assessment of the existing installation. We check for cracks, lifting, poor dressing, and inadequate fixings. We then provide a detailed specification of the replacement work required, including the lead code, joint details, and fixing method.

During installation, we work to Lead Sheet Association best practice standards. Flashings are cut from new rolled lead sheet, dressed to shape, chased into prepared mortar joints, fixed with lead wedges, and pointed with flexible sealant. Every joint is lapped correctly and every piece dressed tightly to its substrate. Our Henley-on-Thames leadwork is built to last decades.
