Houses on the same estate were built together, roofed together and have weathered together, so when one roof on a row needs replacing, the rest often follow within a few years. A new roof means stripping the old covering, checking the timbers, fitting a breathable membrane and new battens, then laying tiles or slate fixed to today's standards. We're roofers based in west Dartford, under a quarter of an hour from Swanley, and we'll give you a written quote that breaks down every part of the job. If a repair would do, we'll say that instead. A new roof is a lot of money to spend on a hunch.
A roofer rings you back to arrange a visit.
A new roof should last decades. These are the parts we put the most care into.
01
Once the old covering is off, we inspect every rafter and the wall plates. Damp, rot or old woodworm get dealt with before new materials go on. On a roof that has been covered for forty-plus years, it's the only way to be sure.
02
Older roofs often still have bitumen felt, which can trap condensation in the loft. We replace it with a breathable membrane that lets moisture escape and keeps rain out, protecting the timbers and any insulation you've added. The difference shows up quickly in a loft that used to smell damp.
03
Older roofs often relied on gravity and mortar to keep tiles in place. A new roof from us has tiles nailed and clipped to the current standard, with ridges and verges mechanically fixed so they don't lean on mortar alone. Mortar-only ridges are one of the faults we repair most often on older roofs.
04
Inland Kent winters bring regular frosts. We fit tiles and slates suited to those conditions and steer clear of cheap, porous products that flake after a few hard winters. Ask about the frost rating of anything you're considering and you'll get a straight answer.
05
Re-covering a roof counts as work to a thermal element, so the insulation should be upgraded at the same time. We'll explain what that means for your loft and include it in the price. Done properly, it makes the top floor more comfortable in winter and in summer.
06
A full re-roof covers more than half the roof, so it needs building control approval. We'll explain the route, deal with the paperwork and make sure you get a completion certificate at the end. Without one, a buyer's solicitor will usually start asking awkward questions.

Most of Swanley was built between the war and the late 1980s, and stays under three storeys. That makes re-roofing here simpler than in towns full of tall Victorian terraces, because the scaffold is lower and quicker to put up. The estates bring their own wrinkles, though. Homes on St Mary's and White Oak are mostly rented from West Kent Housing Association, with some in private hands, so two roofs on the same row can be in very different states.
The older houses need a different approach. Late Victorian and Edwardian homes on Swanley Lane and Birchwood Park Avenue, and the Georgian semis on Goldsel Road, deserve a covering that suits their age. In the Swanley Village conservation area, which has been reviewed several times since it was designated in 1972, a change of material could need consent from Sevenoaks District Council. We'll flag any of this at survey stage.
If the roof is basically sound and only one area has failed, roof repairs in Swanley could save you the cost of a full replacement.
"When we re-roof one house on a Swanley estate, it's common for a neighbour to ask us to look at theirs before the scaffold comes down."
We measure the roof, check its pitch, look at chimneys, valleys and abutments, and inspect the loft. That tells us how much material is needed and whether any structural work is likely. On a typical estate semi this takes about an hour.
You choose between concrete tiles, clay tiles or slate, and we explain the cost, weight and look of each. If you're in Swanley Village, we'll check whether the change needs planning consent.
Building control is notified before the job starts and the inspections are booked in. It protects you, and a properly signed-off roof matters when you come to sell. We handle the notification and tell you the inspection dates in advance.
Scaffold goes up around the house and a skip arrives for the old materials. We agree where both go so your driveway and your neighbours' access stay as clear as possible. It's worth letting the neighbours know a few days before it arrives.
The old roof comes off in sections. We inspect and repair the timbers, replace any damaged rafters and make sure the structure is level and sound before going any further.
Breathable membrane, treated battens and the new covering go on in that order. Tiles are fixed to current standards, ridges and verges are dry-fixed, and lead or flashings are renewed at every junction. Each stage is photographed before the next one covers it.
Building control signs off the finished work. We clear the site, take down the scaffold and give you photos, the completion certificate and the details of your 10-year guarantee. Keep all of it together with the house documents.

Paperwork in your hand on the last day. Not posted out "in due course".
Re-roof a house in Swanley with us and you get 10 years of cover on the workmanship. It's a written document. It has your address on it, lists what was done, and is dated the day the roof is signed off. If water gets in because something was fitted wrong - a batten, a fixing, a lap, a flashing - a roofer comes back and puts it right. You don't pay for that.
Why are we happy to promise ten years? Because of how the roof goes on. Every tile or slate is mechanically fixed to BS 5534, the current British Standard. Ridges and hips are fixed too, not just sat in mortar. A breathable membrane goes down first. Where a roof meets a wall, a chimney or the house next door, it gets proper lead or a tested dry system. Shortcuts there are what make a guarantee expensive, so we don't take them.
Tiles, slates and membranes also carry the maker's own warranty. Those vary by product, and your paperwork tells you which ones apply. If a job is too unusual to guarantee in the normal way, you'll hear that at quote stage.
The table compares the main roof coverings we use. For most Swanley estate homes, concrete tiles are the practical choice. The older houses on Swanley Lane and Goldsel Road may suit clay or slate better.
| Comparison point | Concrete interlocking tile | Clay plain tile | Natural slate | Fibre cement slate |
|---|---|---|---|---|
| Typical lifespan | 50 years or more | 60 to 100 years | 80 to 100+ years, depending on source | Around 30 years |
| Weight | Heavy | Heaviest, as each tile is double-lapped | Light | Lightest of the four |
| Relative cost | Lowest | Mid to high, slow to lay | Mid to high, Welsh slate dearest | Low to mid |
| Look | Chunky profile, common on postwar homes | Small, warm-coloured, traditional Kent look | Thin, dark and neat | Uniform slate look, flatter colour |
| Planning and conservation | Fine for most homes, can jar in a conservation area | Often expected on older Kent buildings | The like-for-like choice for slate roofs | May be refused on listed or conservation roofs |
| Best for | Budget re-roofs on postwar and newer houses | Period homes and steeper pitches | Victorian terraces, slate-to-slate jobs | Lighter swap where rafters are marginal |
Every quote is based on a survey. Here are the four factors that make the biggest difference in Swanley. Each one is listed separately on the quote.
A terraced house in Swanley usually costs £8,000 to £14,500 to re-roof, a semi £10,500 to £16,000 and a detached house from £14,000 upwards. Hipped roofs, dormers and valleys add labour and material compared with a simple gable.
Concrete tiles are typically the lowest-cost option. Clay and natural slate cost more but may suit older homes on Swanley Lane or Goldsel Road better. In the Swanley Village conservation area, the council's view on materials may settle it.
Postwar roofs that have never been stripped can hide rot or damp in the rafters and wall plates. We include an allowance for this in the quote and show you photos of anything beyond it before carrying out extra work.
With scaffold already up, it often makes sense to replace fascias, soffits and gutters, or to add rooflights. Doing them together saves paying for access twice. We price each extra separately so you can pick and choose.
Usually not. Replacing a roof with similar materials doesn't normally need planning permission from Sevenoaks District Council, which handles planning for Swanley. It's different in the Swanley Village conservation area or for a listed building, where changing materials or adding rooflights may need consent. Separately, a full re-roof needs Building Regulations approval because it affects more than half the roof, and if the new covering is 15% or more heavier, the structure has to be checked too.
No, the roof belongs to your landlord, so it's their decision and their cost. Report any leaks or damage to them in writing. If you've bought your home from the association, the roof is now yours, and we can survey it and quote like any other private property. Leaseholders in flats should check their lease, as the freeholder usually controls the roof.
Allow roughly a week to a fortnight for most Swanley semis and terraces, from scaffold up to scaffold down. Bungalows can be quicker, while hipped roofs or houses needing timber repairs take longer. Weather can add a day or two. We'll give you a timescale when we quote and keep you posted as the job goes on.
Late spring to early autumn is easiest, as the days are longer and frost isn't a risk to fresh mortar. Winter isn't off limits. We can work through the colder months, but cold snaps can pause mortar work and short days slow progress. If your roof is leaking now, waiting for summer isn't always sensible.
It's hard to put a figure on it, and we won't pretend otherwise. What a new roof does do is remove a problem buyers' surveyors often flag. An old roof with brittle felt or crumbling ridges can knock money off an offer or slow a sale. A new roof with a building control certificate answers those questions before anyone asks them.
