The roofs in Beverley

Outside the historic core, Beverley is a mix of Victorian and interwar housing and substantial modern estates on the edges of the town. The older stock tends to need ridge, verge, chimney and leadwork long before the covering itself. The newer estates are the familiar concrete tile and felt combination reaching the end of the line together.

Beverley has a large conservation area around the Minster and Saturday Market, so on older property in the centre the covering and the detailing need to be sympathetic as well as watertight.

Valley work in Beverley often runs alongside chimney and ridge work on older property, where several details are reaching the end of their lives at once. Doing them together while the access is up is the sensible sequence.

Planning lead valley replacements behind Beverley's Norwood frontages

Norwood and Hengate contain older brick properties whose slate and pantile roofs can continue into rear wings hidden from the street. Where Norwood roof wings meet, a long lead valley may have been patched repeatedly without addressing how its sections expand and contract. On a Norwood house, a split near a fixed edge can therefore point to movement being restrained rather than damage to the neighbouring tiles. The Hengate valley survey needs to establish the run, slope and existing joints, especially when a rear addition has extended the original channel or changed the way water reaches its lower end.

With a Norwood lead valley, we examine the existing joint arrangement before removing the adjacent covering, then plan suitable section lengths and support for the replacement detail. Access behind a Hengate frontage may involve a narrow courtyard, so scaffold, lead handling and the carrying route need considering together. Lead valley installation behind Norwood exposes the boarding, replaces unsound sections and forms the lead with allowance for movement before the bordering tiles or slates return. For a historic Hengate roof, the property's designation and visible detailing should be checked before substituting a different lining material or changing the valley profile.

A long Norwood lead valley can require several working days when section joints and rear access demand careful staging, while a shorter clear run may be quicker. The itemised written quote for a Hengate valley should account for lead specification, boarding, courtyard scaffold and the surrounding covering to lift. Through the free survey, photographs of what we find in the Norwood channel explain where movement may have been restrained. After renewal behind Hengate, keep debris away from the joints through safe maintenance and avoid rigid patching across the breaks intended to accommodate expansion in the lead lining.

What valley replacements in Beverley involves

• Lead valleysTraditional lead lined valleys formed in the correct code, on new boarding, with the tiles cut and bedded to a clean line.
• Mitred and swept valleysOn plain tile roofs where the original detail is a mitred or swept valley, restored rather than replaced with a trough.
• Metal valleysPreformed metal valley sections where the roof and covering suit them.

That is the short version. There is a fuller explanation of the work, the materials and the detailing on our valley replacements page.

Signs your Beverley property needs this

• Cement mortar filling the valley, which is a previous repair and a certain future leak
• Tiles along the valley cut badly, sitting proud or slipping into the channel
• Cracked or split lead visible in the valley

Why cement in a valley always fails

It is very common to find a valley that somebody has filled with sand and cement, either to stop a leak or to tidy up badly cut tiles. It never lasts. Cement is rigid, the valley moves, and the mortar cracks along its whole length. Worse, it blocks the channel, so water that should be running away sits against the tile edges and finds its way underneath.
