    Overview

    Why a proper roof matters more than any other trade

    Every other trade in your house depends on the roof working. Once water gets in, plaster softens, joists rot, electrics short and insulation collapses. A £400 patch that fails saves nothing if it costs £6,000 in interior damage.

    We offer full re-roofing, slate and tile repairs, flat roof replacement (EPDM, GRP, single-ply), traditional lead work, ridge tile re-bedding, gutter and fascia replacement, chimney repairs and emergency leak response across Yorkshire.

    Who it's for

    Homeowners with leaks, slipped tiles or visible sagging, owners of pre-1990 homes whose original roof is reaching end-of-life, and anyone preparing to sell who needs the roof signed off.

    When you need it

    Visible water staining inside, missing or slipped tiles, sagging ridge line, granules in the gutter (felt/mineral roofs), or simply 40+ years since the original install.

    Why use a professional

    Roofing is high-risk work that requires scaffolding, fall protection and proper detailing at every junction. Cheap roofers skip all three.

    Why It Matters

    Roofing failures we get called out to fix every winter

    Most roof failures are not the tiles themselves — they're the detailing.

    RISK 01

    Mortar-bedded ridges letting go

    Old mortar bedding cracks and lets ridge tiles slip. Modern dry-fix systems use mechanical fixings and last decades. Re-bedding in mortar is now banned in new work under BS 5534.

    RISK 02

    Lead flashings cracked or stripped

    Around chimneys and abutments, failed lead is the single most common leak point. We strip and replace with code 4 or 5 lead to proper laps.

    RISK 03

    Felt failed under tiles

    Original bitumen felt eventually cracks. Once it does, every wind-driven rain event ends up in your loft. Re-roofing with breathable membrane is the only fix.

    RISK 04

    Flat roofs ponding

    Inadequate falls cause water to pool. Pools become leaks. Modern EPDM or GRP roofs need proper falls (minimum 1:80) and verge upstands.

    RISK 05

    Gutters undersized

    Original 100mm gutters can't cope with modern rainfall intensity. Upgrading to 125mm half-round or square-line resolves overflow that's washing your wall.

    Our Process

    A clear five-step system, from first call to final sign-off

    1. 01

      Roof inspection

      We inspect from the ground, in the loft and from a roof ladder or scaffold, then issue a written report.

    2. 02

      Fixed written quote

      Itemised within 48 hours. We separate must-do safety work from nice-to-have improvements.

    3. 03

      Scaffolding & strip

      Full scaffold erected (no ladders for full re-roofs), old covering stripped to the rafters, materials skipped responsibly.

    4. 04

      Re-roof / repair

      New breathable membrane, new battens to spec, tiles or slates fixed mechanically, ridge dry-fixed, all flashings in fresh lead.

    5. 05

      Sign-off & guarantee

      Building Control notification where required, manufacturer warranty registered, written workmanship guarantee handed over.

    In Detail

    Roofing systems and detailing we install

    Different roofs need different specifications. Here's how we choose.

    Concrete tile re-roofs

    The most common Yorkshire spec — Marley, Redland or Russell concrete tiles on 38×25 treated battens over breathable membrane (Tyvek, Klober or Cromar). Cost-effective and 50+ year service life.

    Natural slate

    Spanish or Welsh natural slate for period properties and conservation areas. Hand-cut, copper or stainless nailed, with proper underlay and ventilation.

    Clay plain tiles

    Traditional small-format tiles for older properties. Beautiful but heavier and slower to lay — priced accordingly.

    EPDM flat roofs

    Single-ply rubber membrane installed in one continuous sheet — no joints to fail. Service life 30–50 years. Best for extensions and outbuildings.

    GRP fibreglass flat roofs

    Wet-laid resin and matting cured to a seamless finish. Excellent for complex shapes with upstands and trims.

    Lead flashings & weatherings

    Code 4 (1.8mm) for most domestic flashings, code 5 (2.24mm) for chimneys and stepped abutments. Proper laps, lead clips at edges, no nails through the visible face.

    Ridge & hip systems

    Dry-fix systems (Hambleside, Klober) using mechanical fixings — meeting BS 5534 and removing the failure mode of mortar-bedded ridges.

    Guttering & fascia replacement

    UPVC or aluminium gutters in 100mm or 125mm half-round/square-line, on new fascia and soffit boards. Often combined with a re-roof for one-time scaffold cost.
