Frodsham sits at WA6 on the northern edge of Cheshire, on a ridge of sandstone that rises above the Mersey marshes and the Weaver estuary. The elevation is the key fact about Frodsham roofing. Main Street climbs steadily up the sandstone escarpment, and properties along Castle Street, Church Street and the hilltop roads face south-west across open marshland with nothing significant to break the prevailing wind between here and the Welsh hills.
The property stock is mostly sandstone and tile, period character from the core Georgian and Victorian streets on the ridge, with 1930s and post-war semi-detached on the residential roads lower down toward Overton and Netherton. The period sandstone properties along Church Street and around the old town centre sometimes carry original plain clay tile in warm red, and the exposed elevation means the west and south-west facing slopes lose their verge mortar ahead of schedule. We have found ridge failure on Frodsham properties where the equivalent property in sheltered Tarporley would have at least another ten years of life.
The Mersey marshes also mean persistent dampness from the west, and north-facing slopes on the ridge properties carry more biological growth than comparable exposure elsewhere in Cheshire. Biocide treatment before any mortar repair work is standard practice on Frodsham jobs.
