About Cannon Hill

Cannon Hill is a small residential area between Morden and the Northern Line at Morden South. Almost entirely 1930s semi-detached family homes with traditional pitched roofs. Common work: full re-tiling, insulation upgrades, and chimney repairs.

What we offer in Cannon Hill

A new roof is one of the biggest investments you'll make in your property. Done well, it protects your home for 40-100+ years, lifts kerb appeal, and adds real value to your sale price. Done badly, it costs you sleep, leaks within a few years, and costs a fortune to fix.

When you need a new roof

Most roofs don't fail suddenly — they give years of warning. You probably need a full replacement if:

• The roof is over 25 years old and showing multiple problems
• You've had several repairs in the last 5 years and they keep recurring
• Tiles or slates are visibly deteriorating — cracking, spalling, missing granules
• The felt or membrane underneath has failed in multiple places
• There's visible sagging between rafters
• Multiple leaks in different parts of the roof
• The roof was poorly installed originally (we see this often)

What's involved

A full re-roof isn't just a re-tile. Done properly it includes:

1. Strip the existing roof — remove all tiles/slates, battens, felt/membrane, ridge and hip tiles, lead flashings
2. Inspect the structure — check rafters, trusses, valley boards, fascias for damage or rot
3. Replace any damaged timber — if we find rotten rafters or sarking boards, we replace them at cost
4. Install new breathable membrane — modern high-performance felt that allows the roof to breathe
5. Install new treated battens — pressure-treated softwood battens to BS 5534 standards
6. Fit new tiles or slates — using copper or stainless steel nails and clips
7. Renew all leadwork — valleys, flashings, chimney backs, abutments
8. Re-bed ridges and hips — using mortar or dry-fix systems depending on specification
9. Install new eaves protection — eaves trays and ventilation strips
10. Final inspection and sign-off — plus warranty registration

How long does it take?

For a typical 3-bed semi in Wimbledon, expect:

• Strip and re-tile in slate: 5-8 working days
• Strip and re-tile in concrete tile: 4-6 working days
• Larger detached properties: 7-14 working days

Weather dependent — we monitor forecasts and may pause for safety in high winds or heavy rain.

Building regulations and approvals

In England, re-roofing is typically covered by Building Regulations approval if more than 25% of the roof is being replaced. We handle this for you — most projects are approved through a Competent Person Scheme (we're registered) without need for full plans.

Properties in conservation areas (Wimbledon Village, parts of Putney, Southfields, Carshalton Ponds) may need planning permission as well as Building Regulations. We're familiar with Merton, Wandsworth and Sutton conservation area requirements and will guide you through.

How much does it cost?

Costs vary widely based on size, material, complexity and access. Typical Wimbledon ranges:

• Concrete tile re-roof (3-bed semi): £8,000–£12,000
• Clay tile re-roof (3-bed semi): £10,000–£16,000
• Natural slate re-roof (3-bed semi): £14,000–£22,000
• Larger detached or complex roofs: £18,000–£35,000+
