Twyford is chalk downland village on the River Itchen south of Winchester with a damp valley microclimate. Itchen Valley damp microclimate with persistent humidity October to March; riverside trees add gutter blockage every autumn; accelerated moss and lead fatigue. the Itchen Valley microclimate accelerates lead fatigue at chimney abutments and valley junctions; properties near the river have the highest lead call rate per property. Lead work failures account for a significant proportion of the roof leaks we investigate in Twyford. We install all lead work to the Lead Sheet Association specification using correct-weight lead β code 4 minimum for cover flashings, code 5 for back gutters, valleys and horizontal surfaces.

How We Quote Lead Work
Lead work is surveyed from a ladder or scaffold, inspecting each element individually. We confirm the lead code of the existing lead (which determines whether it has been correctly specified), the extent of failure in each element, and whether re-dressing or full replacement is appropriate. The written quote specifies the lead code to be used on every element β we never install below code 4 for flashings or below code 5 for back gutters and valleys. All Winchester lead work is installed to Lead Sheet Association specification. Free survey, written fixed-price quote. Call 01962 809171.
