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.
    

Benefits 

## What you actually get when we run the job

### Fully scaffolded

Safe access, faster work, better detail. Scaffold cost is included in our quotes.

### BS 5534 compliant

Mechanical fixings throughout, dry-fix ridges, proper underlays. Built to current British Standard.

### 25-year tile warranty

Manufacturer cover on the tiles or slates themselves.

### 10-year workmanship guarantee

Written cover on the install. Transferable when you sell.

### Lead work to code 4/5

Real lead, properly lapped and clipped — not lead-look polymer.

### Emergency response

We carry tarps and temporary repair kit for genuine emergencies.

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.
