Stone, clay and Weald weather in Horsham
Horsham gave its name to a roofing stone. Horsham stone is a sandstone split into thick, heavy slabs, and you see it on the old houses along the Causeway and on the great roof of St Mary's Church. Those roofs weigh far more than tile or slate, so over time rafters spread, ridges dip and slabs slip on perished pegs. We rehang slabs, source reclaimed stone to match, and strengthen tired timbers so the roof holds its shape. On listed buildings, check with the council before any work that changes the roof.
Away from the old town, Horsham sits on Weald clay, and clay from the Weald has been made into bricks and plain tiles here for generations. Those tiles cover the Victorian and Edwardian terraces around the station and Denne Road, and they weather beautifully until frost splits the older ones and the faces flake away. Roffey, Holbrook and Littlehaven add later estates under concrete tiles, while Broadbridge Heath and the new Highwood homes carry dry fix ridges and verges. With St Leonard's Forest and plenty of mature trees nearby, moss and leaf-filled gutters are part of life here.

Common roof faults around Horsham
Frost, trees and heavy old materials are what wear Horsham roofs down.
Sagging Horsham stone roofs
The weight of stone slabs pushes rafters outward and bends battens, so the roof dips and slabs slide. We strip the slope, strengthen the timbers and relay the stone on new battens.
Frost-damaged clay tiles
Water soaks into older clay tiles, freezes and splits the face off. Flaking tiles let in water and crack further each winter, so we swap them for sound reclaimed or new tiles in a matching colour.
Moss under forest trees
Shade from St Leonard's Forest and big garden trees keeps roofs damp, and moss thickens fast. We remove it, clean and treat the tiles, and clear out the gutters it chokes.
Leaf-filled gutters and hoppers
Autumn leaves pack gutters, hoppers and downpipes, and water spills down the walls. We clean them out, repair leaking joints and fit new uPVC runs where the old ones have sagged.

Roofing questions from Horsham
Can Horsham stone roofs be repaired, or do they need replacing?
Most can be repaired. Slipped slabs can be rehung, broken ones replaced with reclaimed Horsham stone, and dipped sections relaid once the timbers underneath are strengthened. A full strip and relay is needed only where rafters have spread badly or the battens have failed right across the roof. We reuse every sound slab, because good stone is scarce and worth keeping.
Why are the clay tiles on my Horsham house flaking?
Frost is the cause. Older and softer clay tiles take in water, it freezes inside them, and the face shears off in thin layers. Once a tile starts flaking it holds more water and fails faster. We replace the damaged tiles with sound ones that match, and check the felt and battens beneath while those tiles are off.
Is moss on my Horsham roof doing any real damage?
Yes, once it gets thick. A moss cushion holds water against the tiles, which feeds frost damage in winter, and it lifts tile edges so rain blows underneath. Clumps that break away end up choking the gutters and downpipes. We remove the moss by hand, clean the roof, treat it and clear the gutters in the same visit.
Can you take down an old chimney on a Horsham house?
We can, either down below the roofline with the gap tiled over, or removed completely at roof level. Plenty of Victorian and 1930s houses around Horsham have stacks serving fireplaces nobody uses, and they still need pointing and flashing. Once the stack is gone, we felt, batten and tile the roof to match, and the loft is left weathertight.
