Why lead details matter so much
Complex shapes sealed properly
Lead can form neat weatherproof details where simpler materials often struggle.
Movement allowed for
Correct sizing and laps help the detail cope with expansion and contraction.
Failure signs read early
Splits, staining and lifting point to junctions that need proper attention.
Lead protects the awkward parts of a roof
The places where roofs change direction, meet walls or wrap around features are often the parts that let water in first. Lead is used there because it is strong, durable and malleable enough to form clean weatherproof details, but it still has to be sized, supported and fixed properly. We repair and install flashings around chimneys and abutments, lead details to dormers and lining or repair work to box gutters. With Roofwise Roofing Services, the job is about getting those vulnerable junctions moving and shedding water the way they should.
Good leadwork allows for movement as well as rain
Common failure signs include splits, lifted sections, poor laps, fatigue and staining near a junction. Those problems often come back when the original detail did not allow properly for support, fixings or thermal movement. We form leadwork with those points in mind so the finished detail can cope with the roof in service, not just on day one.
Through Roofwise Roofing Services, roof junctions get the same care as the main covering, because that is usually where weatherproofing is won or lost.
Frequently asked questions
Why does roof leadwork split or lift over time?
Lead can fail when it is poorly supported, badly sized, fixed too rigidly or not given the right laps and allowance for movement. Over time that stress shows as splits, fatigue or lifting. We look at the formed detail as well as the visible symptom before repairing it.
Can you replace just the flashing around a chimney?
Yes, if the lead flashing is the part that has failed and the surrounding roof remains sound. We inspect the junction first to make sure the leak is not also tied to nearby tiles, slates or masonry, then carry out the repair that fits the full detail.
What is involved in box gutter repair?
Box gutters need careful shaping, support and lining because they carry a concentrated flow of water. If there are splits, weak laps or ponding, we inspect the condition and explain whether local repair or more extensive relining is the better answer.
