Chapter 1: Is our Lower Earley roof due a re-roof, or can the tiles be kept?
What we find
Estate houses of Lower Earley's first years were typically finished with concrete interlocking tiles over bitumen-based felt, fixed to softwood battens. Concrete tiles are tough, and many of these roofs have plenty of life left in the covering. What ages faster is everything under and around it. The felt dries out and cracks where it is exposed at the eaves, the battens can soften where moisture has sat, and the mortar under the ridge shrinks away from the tile.
From the ground, a roof near the end of its working life shows tiles with a rough, eroded surface, patchy green moss that holds water in the joints, and a ridge line that no longer looks crisp. From the loft, you may see pin-prick daylight, damp felt or dark staining on the battens. A single patch of damp rarely means the whole roof has failed, which is why the loft inspection matters.
What we fix
We lift sample tiles in different places, check the battens with a probe, and look at the felt from inside. If the covering and battens are sound, repair is the better value: new ridge fixings, renewed eaves felt and a few replaced tiles. If the felt has failed over most of the slope, a strip and re-cover with new breathable underlay, new battens and either the cleaned tiles or a fresh set is the honest answer.
For a three-bed semi in concrete tile, the typical UK range for a whole re-roof is £6,500 to £10,500, and the price you receive is fixed after the survey. A job of this size is usually notifiable, so we handle building control for you. Our roof replacement page explains what a re-roof involves.
