Specialist leadwork repairs across Slough and the Thames Valley
High class roofing provides professional leadwork services for homeowners across Slough, Windsor, Maidenhead, and the wider 15-mile radius. Based in Datchet, our team, led by Jimmy Frankham, understands that lead is the primary barrier protecting your home against water ingress at critical roof junctions. We specialise in diagnosing and rectifying failed leadwork, from cracked chimney aprons and perished step flashings to leaking lead valley gutters and flat roof bays. Our approach focuses on long-term structural integrity rather than temporary, short-term patches.
Precision chimney flashing and roof junction repairs
Water ingress around the base of a chimney is often caused by the deterioration of the lead flashing or the failure of the mortar in the raggle. Over time, thermal expansion and contraction can cause lead to fatigue or crack, while the lime mortar holding it in place may crumble. We use Code 4 and Code 5 milled lead to provide a durable seal that accommodates building movement. By properly dressing the lead into the masonry and over the roof tiles, we ensure that water is directed away from the junction, preventing internal dampness on your chimney breast and damage to underlying timbers.

Restoring lead valley gutters and drainage systems
The valley gutter is one of the most hardworking elements of your roof, collecting significant rainwater from two adjoining roof slopes. In the Thames Valley, high-intensity rainfall requires these channels to be robust and correctly sized to meet Building Regulations Part H standards. We offer comprehensive lead valley replacement, ensuring that the new lead is dressed correctly to manage flow. For period properties in Windsor or older residential areas in Slough, we maintain the traditional aesthetic and performance requirements while upgrading the material to modern standards, preventing the pooling and seepage that leads to costly structural repairs.

Expert craftsmanship for conservation and period properties
Working in conservation areas such as Windsor, Datchet, and parts of Maidenhead requires a nuanced understanding of historic materials. Whether dealing with traditional lead soakers on a Victorian terrace or complex saddle details around a chimney, our team applies traditional bossing and lead-working skills. We also apply patina oil to new leadwork upon completion, which prevents white carbonate staining from running onto your roof tiles or brickwork, keeping your property looking as it should while protecting the structural integrity of the roofline.

01256 639416Frequently asked questions about our leadwork services
Can you patch old lead or does it need replacing? While minor issues can sometimes be dressed or welded, lead that shows signs of fatigue, splitting, or excessive mortar failure often requires a full replacement to be effective. We will always provide an honest assessment during our site visit. What is the difference between Code 4 and Code 5 lead? Code 4 is standard for most residential flashing and soakers, while Code 5 is thicker and typically used for larger surface areas or regions subject to greater exposure. Why is water leaking through my chimney breast? This is frequently caused by failed flashing at the junction where the roof meets the chimney or by porous brickwork and degraded mortar joints. How long should new lead flashing last? When installed to LSA standards and properly maintained, high-quality leadwork can easily provide 50 to 100 years of service, making it one of the most reliable materials in roofing.
Answers to common questions about our Leadwork Repairs in Slough
How do I know if my chimney flashings need replacing?
You should look for visible signs from the ground, such as lead that has slipped out of the brickwork or pieces that look buckled and thin. Inside your house, brown staining on the chimney breast or dampness in the loft around the stack are clear indicators that the lead flashings or the chimney apron have failed. We can provide a drone or ladder inspection to confirm the exact state of the leadwork.
Can you do a lead roof repair in Datchet on a historic building?
Yes. We are very familiar with the conservation requirements in Datchet and Windsor. We use traditional methods to ensure any new leadwork matches the existing style of the property. This includes using the correct gauge of lead and traditional fixing methods that satisfy local planning expectations for period homes.
What is the difference between Code 4 and Code 5 lead?
The "Code" refers to the thickness and weight of the lead sheet. Code 4 is the standard for most domestic flashings and valleys because it is thick enough to resist cracking but flexible enough to be shaped. Code 5 is thicker and heavier, often used for larger flat roof areas or high-exposure gutters where extra durability is needed. Using the wrong code for the wrong application is a common reason why leadwork fails prematurely.
Why is my valley gutter leaking even though it looks okay?
Often, the leak isn't in the lead itself but in how the tiles are cut over it. If the tiles are too tight to the valley, debris and moss build up, causing water to "bridge" over the lead and into your roof space. Alternatively, the lead might not have a high enough "upstand" under the tiles. We can strip back the tiles to inspect the lead and fix these design flaws without always needing a full replacement.
How long does a lead valley gutter replacement take?
For a standard semi-detached house in Slough or Maidenhead, a valley replacement usually takes one to two days. This includes removing the old lead, checking the timber supports, installing the new Code 4 lead, and re-fitting the tiles. We always aim to leave the roof watertight at the end of every working day.
