When a roof is beyond repair, we carry out a full re-roof done properly, in tile, slate or flat roof systems. Honest advice on whether you really need a new roof, a 10-year workmanship guarantee and a free fixed quote. No call-out charge.
Tell us about your roof. We usually reply the same day.
At Alliance Roofing & Building, we replace worn-out and failing roofs with new roofs built to last. When your roof has reached the end of its life, patch repairs stop being worth the money, and a full re-roof is the honest, long-term answer. We strip the old covering back, put right anything underneath, and install a new roof that keeps your home warm, dry and protected for decades.
We re-roof houses of every type, from Victorian terraces and 1930s semis to detached family homes and bungalows, in concrete tile, clay tile, natural or fibre-cement slate, and flat roof systems where a section of the roof is flat. We serve Surrey, Berkshire, Buckinghamshire, Hertfordshire and West London, and we will always tell you honestly whether a repair will do before we quote you for a replacement.
A roof usually gives you plenty of warning before it needs replacing. If you are seeing several of these together, it is often more cost-effective to re-roof than to keep paying for repairs:
Not sure how bad it is? We will inspect the roof, get in the loft, take photos and give you a straight answer on whether a repair will see you right or a re-roof is the better long-term value.
The most popular choice for pitched roofs across the South East. Hard-wearing, cost-effective and available in a huge range of profiles and colours to match your home.
A classic, elegant finish that lasts for generations. Natural slate for period and conservation-area homes, or lighter fibre-cement slate for a similar look at a lower cost.
Where part of your roof is flat, we install durable EPDM rubber, GRP fibreglass and felt systems as part of the re-roof. See our flat roofing →
The cost of a new roof depends on the size and shape of your roof, the covering you choose, the condition of the timbers underneath, and access for scaffolding. As a rough guide for the South East:
| Property type | Typical roof area | Indicative guide price |
|---|---|---|
| Terraced house | Smaller pitched roof | £5,000 - £9,000 |
| Semi-detached house | Medium pitched roof | £6,000 - £12,000 |
| Detached house | Larger or complex roof | £9,000 - £18,000+ |
| Natural slate roof | Any of the above | Priced at a premium |
Guide figures for illustration only. Natural slate costs more than concrete tile because the material itself is dearer and takes longer to lay. Your written quote is free, fixed and based on a proper inspection, with no call-out charge and no obligation.

We inspect the roof inside and out, take photos and tell you honestly whether a repair will do or a full re-roof is the better value. No call-out charge.
A fixed price with the covering, timescale and guarantee spelled out in plain English, usually back to you the same day.
We erect safe scaffolding, strip the old covering, then replace the battens, felt and breathable membrane so the new roof is built on a sound base.
Your new tiles or slates go on, ridges, verges and flashings are dressed in properly, and we finish with photos and your 10-year workmanship guarantee.
Not every roof that looks tired needs replacing. Plenty of roofs we are called out to just need a targeted repair, and we will tell you so, even when a re-roof would earn us more. We would rather do the honest job and keep you as a customer for the next roof than sell you something you do not need.
If a repair will genuinely see you right for years to come, we will quote you for the repair. If the roof is past saving and you would only be throwing good money after bad, we will explain exactly why, with photos. Either way you get a straight answer. See our roof repairs service if a repair is all you need.

"Full re-roof on our semi. Mitchell and the team stripped the old tiles, replaced the battens and felt and had the new roof on within a few days. Tidy, professional and exactly the price quoted. Highly recommend."
"We thought we needed a whole new roof but they inspected it and told us honestly a repair would do for now. When it eventually did need replacing they were the first people we called. New slate roof looks fantastic."
"Excellent from start to finish. Scaffolding up quickly, old roof off and new tiled roof on with photos at every stage. Left the garden spotless. Ten year guarantee gives real peace of mind."
