Why Homeowners Choose a New Roof Installation in Ealing
If your roof is more than 50 years old, suffers from multiple leaks, shows a sagging ridge line, or needs repeated expensive repairs, a full new roof installation in Ealing often becomes the most cost-effective long-term choice.
What This Guide Covers
In particular, this guide focuses specifically on Ealing properties. You will learn the seven clearest signs that you need a new roof, the materials that suit Victorian terraces in W5, interwar semis in W7 and post-war homes in W13, the exact steps we follow, transparent 2026 prices, and the five checks you should always make before you appoint a contractor.
Our Experience and Standards
Above all, we base every recommendation on more than 15 years of practical experience across West London. In addition, we follow NFRC guidance and the British Standard BS 5534:2014+A2:2018. We also advise on Building Regulations, including thermal upgrades under Approved Document L when we renew a large part of the covering.
Not sure whether you need a full replacement or simple repairs? First, we inspect the loft and the exterior (where safe) and give you an honest written assessment — with no pressure and no obligation. Book your free survey or call 07424 323113.
7 Clear Signs You Need a New Roof Installation in Ealing
- Your roof is over 50 years old and has never been fully replaced
Concrete and clay tile roofs normally last 40–60 years. After that point the underlay, battens and bedding usually reach the end of their life, even if the tiles still look acceptable from the street. - You have multiple leaks from different areas
One isolated leak is usually a repair job. However, three or more simultaneous leaks almost always signal widespread underlay or batten failure. - More than 20–30 % of the tiles have slipped, cracked or broken
Once the damage becomes this extensive, individual replacements cost more than a complete strip-and-re-roof. - You can see a sagging or uneven ridge line
This movement points to problems with rafters, purlins or the ridge board, so a full investigation becomes necessary. - Daylight is visible from inside the loft
The underlay has failed and the covering no longer keeps the weather out. Therefore you should arrange an urgent survey. - Moss roots have penetrated the tile bedding
Surface moss is only cosmetic. In contrast, roots that lift tiles create permanent routes for water to enter. - You keep paying for repairs that never fully solve the problem
Spending £1,000–£3,000 every few years on patches often exceeds the cost of a new roof within a short time.
If any of these signs apply to your property, a professional survey is the logical next step. For isolated issues on a younger roof, see our roof repairs in Ealing page.
Best Materials for a New Roof Installation in Ealing
In fact, Ealing’s housing stock ranges from late-Victorian terraces to 1970s semis. Consequently, the right material must match the original design weight, local climate and any conservation restrictions.
Concrete Interlocking Tiles
- Lifespan: 40–60 years
- Typical cost for a 3-bed semi: £5,000–£10,000
- Best for: 1930s–1970s semis in W7 and W13
- Advantages: Most economical choice and wide colour range
Clay Plain or Pantiles
- Lifespan: 60–100 years
- Typical cost for a 3-bed semi: £6,000–£12,000
- Best for: Victorian/Edwardian properties and many conservation areas
- Note: These tiles are heavier, so we often check the structure first
Natural Welsh Slate
- Lifespan: 80–100+ years
- Typical cost for a 3-bed semi: £8,000–£18,000
- Best for: W5 conservation areas and high-value period homes
- Advantages: Excellent longevity and authentic heritage appearance
Synthetic / Fibre-Cement Slate
- Lifespan: 30–50 years
- Typical cost for a 3-bed semi: £6,000–£12,000
- Best for: Properties that need a slate look but have limited structural capacity
How We Install Every Roof
Furthermore, in every case we use a high-performance breathable underlay, treated battens set to the correct gauge, and mechanical fixings that meet BS 5534. Furthermore, we offer dry ridge and dry verge systems as standard because they remove the long-term problems that mortar can cause.
New Roofs in Ealing: Pitched Roofs, Roof Tiling and Slating
Most new roofs in Ealing are pitched roofs, so the job usually means stripping and re-covering an existing structure. In most cases, the rafters stay and we renew the underlay, battens and covering. However, if timbers are rotten or undersized, we will show you and include any repairs in the written quote.
Generally, roof tiling suits many 1930s semis and later homes, using concrete or clay tiles. By contrast, Victorian and Edwardian terraces often call for natural slate to keep the original look. So we match the covering to the house, and we check conservation area rules first where they apply. For more detail, see our pitched roof specialists in Ealing and our slate roof repairs in Ealing.

New Roof Installation in Ealing – Requirements by Postcode
W5 — Ealing Broadway & South Ealing
Victorian and Edwardian terraces (1880s–1914) dominate this area. As a result, many original Welsh slate roofs are now 100–140 years old.
Key points:
- Conservation areas such as Haven Green, Ealing Common, Ealing Green and Montpelier Park require materials that preserve character. Check current boundaries on the official Ealing Council conservation areas pages.
- Original timber structures were designed for lighter slate. Therefore we assess rafters and purlins before we recommend heavier concrete or clay tiles.
W7 — Hanwell & Boston Manor
Most properties here are 1930s–1940s interwar semis with plain concrete or clay pantiles. Consequently, these roofs are now 80–90 years old. In addition, the nearby Grand Union Canal raises humidity and encourages faster moss growth. As a result, we always specify breathable underlay to protect the older timber.
W13 — West Ealing & Drayton Green
This area contains a high concentration of 1950s–1970s homes, many with flat-roof rear extensions. When we carry out a full new pitched roof, it is often more economical to replace the flat roof at the same time under one guarantee. See our flat roof installation page for details.
The Complete Process for a New Roof Installation in Ealing
We follow a clear, disciplined sequence on every job.
1. Free Survey and Structural Assessment
We inspect the loft and (where safe) the exterior. Then we check rafters, purlins, the ridge board, underlay and battens. Any structural work is identified before tiling begins.
2. Detailed Written Specification and Itemised Quote
We list every element: tile type and profile, underlay, batten size and gauge, valley system, ridge type, flashings and scaffolding. You receive a clear document with no vague “ballpark” figures.
3. Scaffolding
We erect full safe-access scaffolding before any work starts. This step is non-negotiable for both safety and quality.
4. Strip-Out
Next, we remove the existing tiles, battens and underlay and dispose of them properly. We also replace any rotten or damaged timber at this stage.
5. New Underlay and Battening
We lay a breathable membrane and then fix new treated battens to the exact gauge required by the tile manufacturer.
6. Tiling or Slating
After that, we lay the new covering from eaves to ridge. At the same time we form and dress lead flashings at every chimney, abutment, soil pipe and penetration.
7. Ridge, Verge and Finishing
We prefer dry ridge and dry verge systems for longer life, although traditional mortar remains available if you request it.
8. Final Inspection and Written Guarantee
Finally, we carry out a joint inspection with you present, check that the gutters fall correctly, and issue a signed 10-year workmanship guarantee on completion.
Typical Timescale
Most standard 3-bed semis need only 3–5 working days of roofing once the scaffolding is up. Moreover, we make the roof weather-tight at the end of every day so you can continue living in the property without disruption.

London and South-East labour rates sit 20–35 % above national averages, and the ranges above already reflect that premium. We always provide a fully itemised written quote after the free survey so you can compare options on equal terms.
How to Choose the Right Contractor for a New Roof Installation in Ealing
Before you appoint anyone, check these five points:
- Ask for proof of public liability insurance and examine the certificate.
- Insist on a fully itemised written quote that lists materials, labour, scaffolding and contingencies separately.
- Read recent independent reviews on Google, Trustpilot and Checkatrade yourself.
- Demand a written 10-year workmanship guarantee plus the manufacturer warranties.
- Accept only a reasonable deposit (10–25 %). Requests for 50 % or more before work begins are a clear warning sign.
In addition, prefer contractors who demonstrably follow NFRC guidance and BS 5534 and who understand Ealing’s conservation areas and housing stock. You can verify the National Federation of Roofing Contractors at nfrc.co.uk.
Common Mistakes to Avoid with a New Roof Installation in Ealing
- Accepting a vague “new roof £X” quote that contains no detailed specification
- Choosing the cheapest quote without checking insurance, guarantee or local experience
- Ignoring conservation-area rules in W5 and risking enforcement action later
- Failing to upgrade insulation when a large percentage of the covering is renewed
- Leaving the property completely unsupervised — a good contractor welcomes you being present for key stages

Frequently Asked Questions about New Roof Installation in Ealing
How long does a new roof installation in Ealing take?
Most standard 3-bed semis need 3–5 working days of roofing once scaffolding is erected. The total project, including scaffold up and down, usually lasts 7–10 days.
How much does a new roof installation in Ealing cost in 2026?
Most 3-bed semis fall between £5,000 and £15,000 depending on the material. Natural slate and complex roofs cost more. Scaffolding is extra.
Do I need planning permission for a new roof installation in Ealing?
Like-for-like replacement is normally permitted development. However, conservation areas in parts of W5 or any change to the roof profile or materials may require prior approval. Always check with Ealing Council Planning or the Planning Portal. Building Regulations notification is often needed when we recover a significant proportion of the roof — see the Planning Portal Building Regulations page.
Can you carry out a new roof installation on conservation-area properties in W5?
Yes. We specify natural or synthetic slate and appropriate clay tiles that meet conservation requirements and advise on any approvals before we quote.
What is the best material for a 1930s semi in W7 or W13?
Concrete or clay plain tiles that match the original profile, installed with breathable underlay (especially important near the canal in W7).
Should I repair or replace my roof?
Isolated defects on a roof under about 40 years old usually call for repair. In contrast, widespread tile failure, failed underlay, multiple leaks or age over 50 years make a new installation the more cost-effective choice. We give an honest written recommendation after the free survey.
How long will a new roof last?
Concrete tiles last 40–60 years, clay 60–100 years, natural Welsh slate 80–100+ years, and synthetic slate 30–50 years. All our work carries a 10-year workmanship guarantee.
Does a new roof add value to an Ealing property?
Yes. A recent installation with a documented guarantee removes a major point of negotiation for surveyors and buyers, especially on period properties in W5.
Do you offer dry ridge and dry verge systems?
Yes — we recommend them as standard because they need less maintenance and perform better over time.
Can I stay in my home during the work?
Yes. We protect the roof every night and limit noise to normal working hours (approximately 8 am–5 pm).
Will the new roof meet current Building Regulations for insulation?
When we renew a significant area we advise on, and can install, insulation upgrades that meet current thermal performance requirements under Approved Document L.
