Extensions & Orangeries
Pitched or flat, tied into the existing roof or abutting a wall. The most common new roof we install across Ascot.

A roof on a new structure has to satisfy two masters: current building regulations, and a period house that has been settling for a century.
A Different Discipline
New Roofs Against Old Buildings
Replacing a roof means reinstating something that already worked. Installing a new one means creating something that has never existed, on a structure that is itself brand new, butted up against a building that has moved and settled for well over a century.
That junction is the whole job. A new extension roof must be tied into the original roof or wall so the two behave as one building — which, since they will move at quite different rates, means leadwork designed to absorb that movement rather than resist it. Sized and stepped correctly it will last generations. Run as one long rigid sheet, it will crack within a few winters, right at the point that is most disruptive to put back.
On Ascot properties there is usually an aesthetic problem to solve alongside the technical one. A new roof on a substantial period house has to look as though it was always intended, which means matching slate or tile sympathetically and setting out courses to line through with what is already there.
There is also more regulation than most homeowners anticipate. New roofs must meet current standards for insulation, ventilation and structure — not the standards in force when the house was built — and that affects build-up depth, ridge height and sometimes the design itself.
What We Roof
New Structures We Install Roofs On
If it is newly built and needs covering, it is likely something we take on.
Loft Conversions
Working alongside your conversion specialist on dormers, rooflights and the alterations to the main roof that the conversion requires.
Dormers
Cheeks, roof and the flashings that marry them into the main slope — the detail that decides whether a dormer stays dry.
Garages & Outbuildings
New garages, workshops, stores and stabling, in pitched slate or tile or a modern flat system as the design demands.
Garden Rooms & Studios
Home offices, gyms and garden studios, where insulation and ventilation matter every bit as much as they do on the house.
New Build Housing
Complete roofs on new dwellings and small developments, from first truss through to final ridge.
Working Together
How A New Roof Installation Runs
New build work involves other trades, so sequencing and communication matter as much as the roofing.
-
Drawings & Specification
We review the plans, agree covering, build-up and ventilation strategy, and raise anything that will not work in practice before materials are ordered.
-
Programming With The Build
The roof cannot go on before the structure is ready, and every trade after us waits on the building being watertight. We book realistically and hold the date.
-
Weatherproofing First
Membrane, battens and covering go on to close the building in as quickly as possible, so internal trades can get started.
-
Tying In & Finishing
Leadwork to abutments, flashings into the existing roof, and roofline completed so the new work reads as part of the original house.
Planning An Extension Or Conversion?
Speak to us before the drawings are signed off. Roofing input at that stage costs nothing and regularly avoids expensive compromises later.
What's Involved
What A New Roof Installation Covers
Everything from the membrane up, plus the junctions that connect new work to old.
- Breathable membrane, treated battens and the chosen covering
- Natural slate, clay tile or a modern flat roof system
- All leadwork tying new work into existing roofs and walls
- Valley formation where a new pitch meets the original roof
- Dormer roofs, cheeks and their flashings
- Lantern and rooflight kerbs built and detailed in
- Fascias, soffits, guttering and downpipes on new elevations
- Eaves and ridge ventilation designed to current standards
Why Us
New Work That Looks Original
The measure of a good extension roof on a period house is that a visitor cannot see where the original stops.
- Coverings matched sympathetically, with course lines set out to line through
- Junctions formed in dressed lead, sized and stepped for movement
- Ventilation and insulation specified to current regulations
- Realistic programming so following trades are never left waiting
- Direct liaison with your builder, architect or project manager
Common Questions
New Roof Installation Questions
What homeowners, builders and architects ask before a new roof goes on.
Cannot see your question? We are always happy to talk it through — there is no such thing as a silly question when it comes to your roof.
Can you work alongside my builder or architect?
Regularly, and it is how much of our new build work arises. We liaise directly on sequencing and detailing so nobody is waiting on anybody else, and you are not left relaying technical questions between two trades who ought to be talking to each other.
Will the new roof match my existing one?
That is always the aim and on a period property it matters enormously. Where the original slate or tile is still available we use it; where it is not, we source the closest match in size, colour and texture. A new covering will read brighter until it has weathered a season or two.
Do I need building regulations approval?
For an extension, dormer or loft conversion, yes — the roof forms part of that application and must satisfy current thermal, ventilation and structural requirements. We build to those standards and provide whatever detail your building control officer asks for.
How quickly can the building be made watertight?
It is normally everyone’s priority on site, since the internal trades cannot begin until it is. Once the structure is ready for us, membrane and battens go on quickly, and we will always prioritise closing the building in over finishing cosmetic detail.
Can you roof a garden room or home office?
Yes, and they repay doing properly. A garden room with poor insulation or no ventilation becomes an unusable room — freezing in winter, unbearable in summer and prone to condensation. On a small building the roof build-up matters more, not less.
Do you fit the guttering on new work too?
We do. Fascias, soffits, guttering and downpipes on new elevations are all part of the installation, matched to the existing roofline and discharged somewhere sensible rather than onto a path.
