Roof Replacement In Weymouth
Is it time your roof was done properly, once?
Complete re-roofs in natural slate, clay and concrete tile, built to current standards with a 10 year guarantee
A new roof is something most people buy once in a lifetime, so it's worth understanding what you're paying for. When we replace a roof in Weymouth we take it right back to the rafters, check every timber, and build it up again with breathable membrane, treated battens and a fixing for every single slate or tile. The result should see out the next forty years or more. It comes with a 10 year guarantee on our workmanship as standard, and a fixed price agreed before the scaffold goes up.

Why a properly built new roof is worth the outlay
The difference between a good re-roof and an average one is almost all hidden underneath. These are the parts that matter most.
01
Every slate and tile mechanically fixed
Current British Standard guidance means nothing on a new roof should rely on its own weight to stay put. Ridges and hips are fixed mechanically too, not just bedded in mortar.
02
A breathable membrane underneath
Modern vapour-permeable underlay lets moisture escape from the loft while keeping driven rain out. Many older roofs here have perished bitumen felt or none at all, so this is often the single biggest upgrade.
03
Timber checked and put right
Once the old covering is off, rafters, wall plates and fascia boards are open to inspection. Anything soft or split is repaired or replaced before the new roof covers it up again.
04
Ventilation designed in
Condensation in lofts causes as much damage as rain. Eaves, ridge and tile vents are planned into the new roof so the loft stays dry, especially if you've added insulation.
05
Junctions done in lead
Chimneys, abutments and valleys are where re-roofs most often go wrong. We dress them in code-appropriate lead or a proven dry system, never a mortar fillet that cracks within a few winters.
06
A 10 year guarantee as standard
On a roof replacement, your guarantee is a signed document handed over with the completion photos. It sets out what was installed and what's covered.

Re-roofing in a town built in two big waves
Walk from the harbour up through Rodwell and out towards Southill and you pass through most of the last two centuries of British roofing. Welsh slate on the Victorian terraces, often well past the century mark and running out of nail. Interwar clay tiles on the semis. Then long streets of postwar houses in concrete interlocking tiles that were put up quickly and are now reaching the age where the felt underneath has gone brittle.
Each of those needs a slightly different conversation. On the older streets it's often about matching slate and keeping the look of a terrace consistent, and in a conservation area that matters to the council as well as the neighbours. On the postwar estates it's usually about the hidden layers: underlay, battens and the fixings that a 1960s roof simply never had.
"On most of the postwar roofs we strip in Weymouth, the tiles are still sound - it's the felt and battens underneath that have failed."
How a Weymouth roof replacement runs, start to finish
- 1
Free survey and roof measure
We inspect the roof outside and from the loft, measure every slope, and note the timbers, chimneys, vents and any conservation-area or listed-building considerations.
- 2
A detailed written quote
Materials are named, not described vaguely. The quote covers scaffold, skip, labour, membrane, battens, fixings, leadwork and VAT, so you can compare it fairly with anyone else's.
- 3
Scaffold and protection
Scaffold goes up with edge protection, and set out so people can still get by where it stands over a pavement. Gardens, conservatories and driveways are covered before stripping begins.
- 4
Strip back to the rafters
The old covering, felt and battens come off in sections so the roof is never left open overnight without temporary sheeting. Timbers are inspected as soon as they're exposed.
- 5
Membrane, battens and lead
Breathable underlay goes on, then treated battens to the correct gauge for your chosen slate or tile. Valleys, abutments and chimneys are dressed in lead or a tested dry system.
- 6
New slates or tiles fixed
Every slate is nailed or hooked and every tile clipped or nailed. Ridges, hips and verges are mechanically fixed, and ventilation is built in at the eaves and ridge.
- 7
Inspection, clean-up and handover
We walk the finished roof, clear gutters and downpipes, remove the scaffold and take away every scrap of waste. You get completion photos and your signed 10 year guarantee.
Ten years on a new roof, written down and signed
When we replace a roof in Weymouth, the paperwork you're handed at the end will, on all but a handful of unusual jobs, include a 10 year guarantee on the work. If yours is one of the exceptions, you'll know at quote stage, not after. It names your address, says what was done and is dated the day we sign the roof off. It covers the installation itself, meaning the battens, membrane, fixings, the slates or tiles and the junctions where the roof meets walls and chimneys. If any of that lets water in through a fault in how it went on, we come back and fix it without charging you.
A guarantee that long only makes sense if the roof is built properly underneath, so it shapes the job from day one. Every slate or tile is mechanically fixed to the current British Standard rather than relying on its own weight, which matters on a stretch of coast where the wind arrives with nothing in its way. Breathable membrane goes on before the battens. Valleys, abutments and chimneys get proper lead or a tested dry-fix system, never a smear of mortar that cracks in its third winter.
Materials carry their own manufacturer cover on top, and that differs from product to product. Your paperwork says which one applies to your roof.

What to look for in a roof replacement company
A quote that names the materials
"New slate roof" isn't a specification. A quote you can trust names the slate or tile, the membrane, the batten size and the fixing method, and says what happens at the chimneys and valleys. If two quotes are thousands apart, the difference is usually hiding in exactly these lines.
They expect to find something under there
Nobody knows exactly what's beneath a roof until it's stripped. A sensible quote explains how unexpected timber repairs will be priced, ideally as a rate per metre, so you aren't presented with an open-ended bill halfway through the job.
The guarantee is written down
Ask to see an example of the guarantee before you sign. It should name the installer, say how long it lasts and what it covers. A verbal promise from a firm you can't find in five years' time is worth very little.
Natural slate, clay tile or concrete tile?
The three roof coverings we fit most often around Weymouth. Each is a good choice in the right place. These are rough guides for a typical house rather than guarantees.
| Comparison point | Natural slate | Clay plain tile | Concrete interlocking tile |
|---|---|---|---|
| Expected lifespan | 80 years or more for good quality slate | 60 years or more | 40 to 60 years |
| Weight on the roof | Light | Heavy, needs sound timbers | Heavy |
| Minimum pitch | Generally 20 to 25 degrees, varies by size | Steep, usually 35 degrees and over | Low, some profiles to 15 degrees |
| Appearance | Traditional on Georgian and Victorian streets | Warm, textured, suits interwar houses | Practical, common on postwar estates |
| Relative cost | Highest | Mid to high | Lowest |
| Planning in conservation areas | Often the expected material | Acceptable where it matches | May not be accepted on older streets |
Choosing a roof that suits the house and the street
Most of the time the right covering is the one the house was built with, or the one its neighbours wear. A Victorian terrace in slate looks wrong in concrete tiles, and in a conservation area the council may well say so. On a 1960s semi there's more freedom, and a modern fibre-cement slate or a good concrete tile can be the sensible middle ground.
We'll bring samples to the survey, talk about weight, pitch and budget, and tell you which options we'd steer clear of on your particular roof.

What a new roof costs in Weymouth
A small terrace re-roofed in concrete tile sits at the lower end. A larger semi in natural slate, or a detached house with hips, dormers and chimneys, sits towards the top. Scaffold, skips and any timber repairs make up a bigger share of the total than most people expect, which is why we itemise them.
Roof replacement questions
How long does a roof replacement take?
A typical terrace or semi takes one to two weeks once the scaffold is up. Larger or more complicated roofs, or long spells of bad weather, can stretch that. We never leave a stripped section open overnight without secure temporary covering.
Is planning permission needed for a new roof in Weymouth?
Replacing a roof like-for-like doesn't normally need planning permission. If you live in a conservation area, in a listed building, or want to change the material or shape, check with Dorset Council first. We can help you work out which applies.
Do I need Building Regulations approval?
Re-roofing has to meet the Building Regulations. If more than half of the roof is stripped and rebuilt, Part L expects the insulation to be brought up to the current standard where that's practical, and the new covering mustn't overload the timbers. We deal with the building control side as part of the job and tell you what paperwork you'll receive at the end.
What does the 10 year guarantee cover?
It covers our installation: the membrane, battens, fixings, slates or tiles, ridges and the lead or dry-fix junctions. If water gets in because of a fault in how the roof was installed, we return and put it right at no cost. Manufacturer cover on the materials comes on top.
Will we have to move out while the roof is done?
Yes. Almost everyone does. There's some noise and dust in the loft during the strip, so clear anything precious out of the loft space before we start.
Can I add insulation at the same time?
It's the ideal time. With the roof open we can improve ventilation and, where it suits the house, add insulation between or over the rafters. We'll talk through the options and the effect on cost at the survey.
