The roofs in Gainsborough

Gainsborough's older housing stock often still carries its original covering, and on slate roofs the slate itself is frequently sound with only the fixings gone. A strip and re-lay using the existing slate is a very different job to a full replacement, and worth establishing before you take a price.

Gainsborough sits on the Trent with older terraced streets near the centre and estate housing around them, and very little shelter from the west.

Valleys on Gainsborough's older terraced property are frequently lead that has cracked along its length, or a previous repair filled with mortar. Either way the fix is to take the covering back and re-line the channel properly.

Valley replacements around Gainsborough's Spital Terrace roof projections

Spital Terrace and the nearby Spring Gardens streets contain older properties with varied roof outlines, including Victorian buildings whose projecting features interrupt an otherwise continuous slope. Where a Spital Terrace gable meets a slate roof, short valleys can disappear behind the projection when viewed from street level. A stain beside a Spring Gardens upstairs window may result from water entering at the top of that valley rather than directly above the mark. On a Spital Terrace roof, checking the head where the two channels meet the main slope is therefore as important as examining the exposed lower lining.

For a valley beside a Spital Terrace projection, we plan scaffold to reach above the feature before deciding whether the defect is confined to one short channel. The usual Spital Terrace opening sequence lifts slates around the valley head, inspects the support and underlay junction, then works down the channel so the replacement sheds water continuously to its outlet. Near Spring Gardens, street frontage access and limited rear space can affect where materials are lifted and stored. Any conservation requirements at a Spring Gardens property should inform its valley lining and slate details, with the paired valley junction checked before the surrounding courses conceal it again.

A short Spital Terrace dormer valley can take longer than its length suggests when the hidden head or neighbouring channel also needs opening. For a Spring Gardens projection, the itemised written quote needs to account for access height and rebuilding the concealed valley support beneath individually cut slates. The free survey investigates the Spital Terrace upper junction, with photographs of what we find explaining whether both channels are involved. Following renewal near Spring Gardens, observe the window reveals during rain and arrange safe clearance behind the projection if debris collects, keeping the repaired valley head able to shed water onto the lining below.

What valley replacements in Gainsborough involves

• Lead valleysTraditional lead lined valleys formed in the correct code, on new boarding, with the tiles cut and bedded to a clean line.
• Cleaning and clearingValleys cleared of moss, debris and old mortar so they run properly again.
• 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 Gainsborough property needs this

• Moss and debris packed into the channel so water backs up under the tiles
• Cracked or split lead visible in the valley
• Rust or holes in an old metal 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.
