Valley replacements in Hull

Valley replacements in Hull

Valley replacements in Hull. We survey the roof first, photograph what we find and give you an itemised written quote, so you know what you are paying for before anyone starts. Our Hull office covers Hull on 01482 424 674.

Hull is in the middle of our Hull patch, so it is part of the Hull office's normal patch rather than a job we have to travel for. It covers the HU1, HU2, HU3, HU4, HU5 and HU9 postcode districts. That matters when you need somebody back to look at something.

The roofs in Hull

Hull is the most mixed roof stock we work on. The Avenues and the terraces off Beverley Road and Newland Avenue are largely Victorian and Edwardian, which means natural slate, lead valleys and party wall abutments shared with the house next door. Move out to Bransholme, Sutton and the west of the city and it is post war concrete interlocking tile on felt underlay, most of it laid within the same twenty year window and now arriving at the end of its fixings together.

Hull's housing runs from the Avenues and the terraces off Beverley Road through to the post war estates north and east of the centre, and the roofs change completely as you move between them.

Valleys are a common source of leaks in Hull, particularly on terraced and semi detached property where two roofs meet. Cement filled valleys, left behind by an earlier repair, are one of the most frequent things we find and one of the most reliable causes of a returning leak.

Valley replacements that respect Hull's Garden Village roof shapes

Garden Village's steep clay tiled roofs around James Reckitt Avenue include projecting gables and smaller roof sections whose intersections need careful valley assessment. On Garden Village's early twentieth century housing, small plain tiles can form a traditional swept detail rather than the open trough familiar on a larger concrete tiled roof. A leak beneath a Garden Village junction therefore does not automatically call for cutting out a wider channel and inserting a modern lining. The Garden Village valley survey needs to identify how the original tiles turn through the valley, and whether the failure lies in that arrangement, the supporting timber or an earlier alteration.

Before a valley replacement around James Reckitt Avenue, we record the tile courses and establish the property's conservation requirements, because changing a visible roof junction can affect its character. James Reckitt Avenue valley access needs scaffold suited to the steep slope, with protection for hedges and the garden path below the projecting gable. On a Garden Village tiled valley, the usual repair sequence is careful lifting, inspection of underlying support and reinstatement of the appropriate weathering detail before the small tiles are relaid. Where a Garden Village trough is suitable for renewal, its replacement should be specified around the actual tile arrangement and pitch.

Rebuilding a Garden Village tiled valley takes longer than exchanging a straight trough, particularly where matching small tiles must be sorted and cut. The free survey around James Reckitt Avenue records that tile arrangement, with photographs of what we find explaining whether the original valley form can be retained. Scaffold geometry, usable tiles, support condition and conservation requirements belong in the itemised written quote for the Garden Village junction. After reinstatement near James Reckitt Avenue, arrange safe debris clearance and avoid pressure washing the valley, which could disturb the closely arranged tiles beside the newly repaired channel.

What valley replacements in Hull involves

• Mitred and swept valleysOn plain tile roofs where the original detail is a mitred or swept valley, restored rather than replaced with a trough.
• Valley boards and structureThe boarding and any structure under the valley checked and replaced where it has been wet for years.
• Cleaning and clearingValleys cleared of moss, debris and old mortar so they run properly again.

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 Hull property needs this

• Tiles along the valley cut badly, sitting proud or slipping into the channel
• A persistent leak in a room below the junction of two roof slopes
• 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.

What affects the price in Hull

• Lead, GRP or metal, and the code of lead where lead is used
• Whether the boarding underneath is sound
• How far the tiles have to be lifted back on each side
