The roofs in Lincoln

Lincoln's position on the edge of the limestone escarpment matters more than people expect. Properties uphill and out along the Cliff take the westerly weather with very little in front of them, which is why so much of the work up there is at the ridge, the verge and the chimney rather than in the middle of the slope.

Lincoln's roofs change dramatically between the uphill conservation area around the cathedral, where slate, pantile and lead detailing are the norm, and the post war estates downhill and to the south.

Lincoln's older property has more complex roof shapes and therefore more valleys, including swept and mitred valleys on plain tile roofs that need restoring rather than replacing with a trough.

Valley replacements where Lincoln's Monks Road roofs change pitch

The older terraces around Monks Road and the Arboretum can combine Victorian slate slopes with later rear additions, producing valleys where two roof pitches differ. At a Monks Road valley, the steeper surface may send water towards the opposite tile or slate edge rather than neatly down the centre. A Monks Road valley that has been narrowed by successive repairs can be especially difficult to judge from a rear window. The important Monks Road valley survey detail is the relationship between the two contributing slopes, including any higher roof discharging into them, rather than assuming every valley can accept the same preformed section.

For an unequal pitch valley near the Arboretum, we measure both roof faces and inspect the upper junction before choosing a replacement lining and clear channel width. Scaffold access behind a Monks Road terrace may need careful planning through a passage, with a platform that reaches the valley without loading the lower extension roof. The usual Monks Road valley sequence lifts the edge coverings, renews deficient support and forms the new channel before the slates or tiles are cut and reinstated. Where an Arboretum area property has conservation protection, the visible material and junction treatment should be checked before that specification is finalised.

The free survey of a Monks Road valley measures the adjoining slopes before a channel is specified, supported by photographs of what we find at their upper junction. Setting out unequal pitches near the Arboretum takes longer than a symmetrical valley, and restricted rear access can spread renewal across several workable days. Scaffold, support repairs and individually cut slates should be identifiable in the itemised written quote for the Monks Road junction. Afterwards, keep the Arboretum area valley mouth clear and observe its discharge during heavy rain from a safe position, noting water that overshoots the receiving gutter.

What valley replacements in Lincoln involves

• Lead valleysTraditional lead lined valleys formed in the correct code, on new boarding, with the tiles cut and bedded to a clean line.
• Valley boards and structureThe boarding and any structure under the valley checked and replaced where it has been wet for years.
• Mitred and swept valleysOn plain tile roofs where the original detail is a mitred or swept valley, restored rather than replaced with a trough.

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 Lincoln property needs this

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

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.
