New Roof Specialists across the North West.

A full reroof is the right call when repairs stop being economic: when more than a third of the tiles are cracked or porous, when the underlay is split and no longer shedding water, or when the battens have rotted through. On most post-war semis across Liverpool, Wirral, Chester and Cheshire, that point arrives somewhere between 40 and 60 years after the original build. We survey first, strip everything back to the rafter line, and fit a complete new system that BS 5534 requires at every layer.

Stockholms has been reroofing in this region long enough to know that two streets in the same town can need different solutions. The detached stock around Heswall and Upton sits on heavier rafters than the terrace belt running through Toxteth and Bootle, and the material call reflects that. We do not fit one tile everywhere.

Materials we run

On the dominant concrete-tile stock, the replacement we specify most often is Marley Edgemere or Marley Duo Edge in slate grey or smooth grey. Both are BBA approved and carry a 60-year manufacturer guarantee. Where the property is in a conservation area or the planners require a specific profile, we move to Cembrit fibre cement or, on listed stock, to Welsh slate from the Penrhyn quarry in Bethesda.

Underlay goes in as Tyvek Pro or an equivalent vapour-permeable membrane across the whole deck before any batten or tile is fixed. That is not optional on a new roof; Part L of the Building Regulations requires minimum U-values that a dry-fix system without vapour control will not meet.

Ridge and hip units are mechanically fixed rather than mortar bedded on all new roofs we put on. Mortar bedding was standard until BS 5534:2014 tightened the wind uplift requirements. Dry-fix is now the correct spec, and it outlasts mortar in salt-air exposures by a considerable margin.

When a reroof makes more sense than a repair

If the repair cost is more than 40% of what a new roof would cost, the repair is rarely good value. You get a patched job on an ageing deck with ageing underlay. A second call-out tends to follow inside three years. We will always tell you which side of that line your roof sits on after inspection, and we will not push a reroof if the case does not stack up.

Original Welsh slate in good condition is an exception. Individually cracked slates can be swapped out for decades on a structurally sound deck. Welsh slate done right outlasts the owners of the house.

What it costs and why

A standard semi-detached reroof in the CH, L or WA postcode areas runs between £5,000 and £9,500 depending on pitch, roof area, chimney count and whether the existing battens need replacing. Welsh slate or conservation-grade clay materials add 30 to 50% over standard concrete tile. We quote fixed-price after a free survey, so what we quote is what you pay.

What we back it with

Every new roof comes with a 10-year workmanship guarantee backed by our FMB membership and an insurance-backed guarantee through Q Assure. The Marley tile system itself carries a 60-year manufacturer guarantee. We register that guarantee in your name on the day the scaffold comes down.
