Service overview
What New Roof Installations Involves
A new roof installation means stripping the existing roof covering, checking and replacing battens and underlay, and laying a complete new roof. Done properly, it gives you a roof you don't need to think about for a very long time, with none of the repeated patching and worry of an old one.
It's for homeowners whose roof has reached the end of its life, widespread slipped or broken tiles, sagging, recurring leaks, rotten battens, or whose roof was badly done in the first place. One of our reviewers came to us after being left with a poor roof replacement by someone else; we carried out a full replacement at an excellent price with good workmanship.
A new roof is one of the biggest investments you'll make in your home, and it's the part of the building that protects everything else. Choosing an experienced, straightforward roofer matters. Our customers describe us as friendly, straightforward and never pushing unnecessary extra work, with fair pricing and regular updates throughout the project.
The cost of waiting
What Happens If It's Left
An old roof that's past repair will keep costing you money. Each winter brings more slipped tiles, more call-outs and more risk of water damage inside the house, and the eventual replacement doesn't get any cheaper.
Repeated repair bills
Patching a failing roof year after year can add up to a significant part of the cost of replacement.
Hidden timber damage
Long-term leaks rot battens and rafters, adding structural work to the eventual job.
Internal damage
Ceilings, insulation, decorations and belongings are all at risk from ongoing leaks.
Reduced property appeal
A visibly tired or failing roof is a red flag for buyers and surveyors.
Common mistakes homeowners make
- Delaying replacement until a storm forces an emergency job.
- Choosing a roofer on price alone: cutting corners on underlay and battens shortens the roof's life.
- Not asking what's included: stripping, battens, underlay, ridge, verges and waste removal.
- Being pushed into replacement when repairs would do: always get honest advice first.

In detail
A Closer Look at New Roof Installations
Choosing a roof covering
The right material depends on your property, its surroundings and your budget. Clay plain tiles suit many Kent cottages and period houses and weather to a traditional look. Concrete interlocking tiles are cost-effective and robust, and common on post-war homes. Natural slate is thin, elegant and long-lived, and typical of Victorian terraces. Matching the character of your street matters too, especially in older town centres.
What's underneath matters most
The tiles are only the visible layer. Underneath, battens hold the tiles and a breathable underlay acts as a secondary barrier against water and wind. On older roofs the original underlay may have perished or be missing entirely. A new roof replaces all of this, which is why a full replacement solves problems that no amount of tile repair can.
Ridges, hips, verges and ventilation
The details are where a roof succeeds or fails. Ridges and hips must be securely fixed, verges finished neatly and weather-tight, and flashings to chimneys and walls properly dressed. Adequate roof ventilation helps prevent condensation building up in the loft. These are the areas where corner-cutting shows up first.
Replacing a poor previous roof
Sadly, a good number of new roofs we fit replace ones that were installed badly: underlay not lapped properly, tiles not fixed correctly, flashings missing. If you've been left with poor workmanship, we can assess what's wrong and give you an honest view of whether it can be rectified or needs replacing.
Planning around weather and your household
A re-roof involves the house being partly open to the weather, so the work is planned carefully and the roof is kept protected at the end of each day. We'll talk you through what to expect, access, scaffolding, noise and timescales, before work starts, and keep you updated as it progresses.
Signs your roof may need replacing
Common signs include widespread slipped or broken tiles, a sagging roofline, daylight visible through the roof in several places, recurring leaks in different spots, crumbling or delaminating tiles, and underlay that has perished or is missing. On older roofs, the original nails and battens can also fail across the whole roof, causing tiles to slip repeatedly. One or two of these on their own may be repairable; several together usually point towards replacement.
The age of the roof alone doesn't decide it. Some old roofs have years of life left; some newer ones were installed so badly that they fail early. The only way to know is to have the roof looked at properly by someone who'll give you a straight answer.
Scaffolding and access
Most full re-roofs need scaffolding to give safe access around the roof edges and a secure working platform. The scaffold also provides protection for people below while old materials are being stripped. Access requirements vary with the property, terraced houses, bungalows and detached homes all present different challenges, and they're factored into the quote.
Questions to ask any roofer before a re-roof
Ask what the price includes: stripping and disposal of the old roof, new battens and underlay, ridges, hips and verges, flashings, and scaffolding. Ask what warranty applies and what it covers. Ask how you'll be kept updated during the work. And read recent reviews from homeowners who have had similar work done. A good roofer will be happy to answer all of these clearly.
