The service
Roofing built to the same standard as our extensions
DBD Builders Ltd carries out roofing as a genuine part of the wider building service, not as a bolt-on trade. Whether it is the roof going onto a new extension, a full re-roof of an existing home, or a standalone repair to fix a leak, the same team, the same survey process and the same fixed-price approach apply. This matters because roofing is one of the areas where corners cut early show up years later as leaks, sagging felt, or slipped tiles.
Tom Dobson has 26 years of hands-on building experience, and roofing has been part of that from the start, whether forming the shell of a new extension or repairing an existing pitched roof that has been neglected for years. Where roof alterations form part of a structural change, such as a dormer for a loft conversion, the structural engineer we work alongside designs the opening and building control is involved through to sign-off.
We work on both pitched and flat roofs, covering tiling, slating, felt and single-ply flat roofing systems, fascias, soffits and guttering. Roofing jobs are quoted as a fixed price after a free survey, so you know the figure before scaffolding goes up, and if additional work is found once the roof is opened up, it is quoted and agreed separately rather than added to your bill without discussion.
This service covers homeowners across Aylesbury and throughout Buckinghamshire, including High Wycombe, Amersham, Beaconsfield, Chesham, Tring, Wendover, Princes Risborough, Great Missenden, Marlow, Gerrards Cross and Leighton Buzzard, on everything from a single repaired section of a roof to a complete re-roof of a large detached house.
Who it is for
- Homeowners with a roof leak or visible slipped or missing tiles
- Anyone extending or converting a loft who needs new roof structure and covering
- Owners of an older roof that has reached the end of its working life
- Anyone with flat roofing on a garage, extension or dormer that needs replacing or repairing
When it is needed
- Water staining appearing on ceilings or in the loft space
- Tiles or slates visibly slipped, cracked or missing after weather damage
- A flat roof is ponding water or the covering has clearly perished
- You are extending or converting and the roof structure needs to change to suit
Why this is not a job to take on unmanaged
A roof has one job — keeping water out — and it only takes one badly detailed junction, one poorly lapped felt, or one incorrectly fixed tile to let water in somewhere it will do real damage before anyone notices. Roofing needs to be done properly the first time, by people who understand how the covering, the structure and the detailing around chimneys, valleys and abutments all work together.

Free survey, normally within a week. Fully insured, and the price you agree is the price you pay for the scope quoted.
What you get
What roofing with DBD actually gets you
Fixed price agreed before scaffolding goes up
You know the cost for the agreed scope from the outset, rather than facing extras once the roof is already stripped.
Detailing given the attention it needs
Valleys, flashings and abutments — the areas where roofs actually leak — are treated as the priority, not an afterthought to the plain tiled area.
Structural roof work engineer-designed where needed
Dormers and structural roof alterations are designed with the structural engineer we work alongside and taken through building control to sign-off.
Pitched and flat roofing under one contractor
Whether your roof is tiled, slated or flat, the same team and the same quoting process apply, so mixed roofscapes on extensions are not split between separate trades.
One team from roof to finish
Where roofing is part of a bigger extension or loft conversion project, the same team continues through to the finished internal space, avoiding handover gaps between separate contractors.
26 years of building experience behind the work
Roofing has been part of Tom's hands-on building work throughout his 26-year career, from new roofs on extensions to repairs on older properties.
What it costs to wait
Why a poorly done roof causes problems well after the work finishes
Roofing problems are rarely obvious immediately. A poorly lapped flashing around a chimney, an under-specified flat roof covering, or tiles fixed without the right batten spacing can all look fine on the day the job finishes and start causing damage a year or two later, by which point water has already got into timbers, insulation or ceilings below.
The other common issue is roofers who focus only on the visible covering and ignore the detailing that actually keeps water out — valleys, abutments, chimney flashings and verge details. These are the points where the vast majority of roof leaks actually originate, not in the middle of a plain tiled slope.
Mistakes we get called in to undo
- Patch-repairing a roof repeatedly instead of addressing the underlying cause
- Using mismatched tiles or slates that do not weather consistently with the rest of the roof
- Choosing a flat roof covering not rated for the exposure or foot traffic it will see
- Ignoring loft ventilation when re-roofing, leading to condensation problems
- Ignoring detailing around chimneys and valleys in favour of the plain tiled area
Water ingress from poor detailing
Valleys, chimney flashings and abutments are where most leaks start. Poorly detailed junctions let water in gradually, often unnoticed until timber or ceiling damage appears.
Structural timber left exposed to weather
If a re-roof takes longer than it should, or is left partly stripped without adequate temporary cover, structural timbers can be exposed to rain and start to deteriorate before the new covering goes on.
Under-specified flat roofing
Flat roofs need the right fall for drainage and a covering system suited to the exposure and use of the roof. Get the specification wrong and ponding water shortens the roof's working life significantly.
Working at height without proper safety measures
Roofing is high-risk work. Scaffolding, edge protection and safe access need to be in place properly, both to protect the workforce and to avoid damage to the property below.
Our process
How the job runs from first call to sign-off
The same sequence on every project, so you always know what happens next and who is responsible for it.
STEP 01
Free roof survey
Tom inspects the roof from the ground, the loft space and, where needed, close up, to identify the covering type, structural condition, and any specific problem areas such as valleys, flashings or flat roof sections.
STEP 02
Fixed-price quote
You receive a fixed quote for the agreed scope, normally within a week of the survey, covering the covering type, any structural timber work, and detailing such as fascias, soffits and guttering.
STEP 03
Scaffold, access and weather protection
Scaffolding and edge protection are put up before any covering is stripped, and temporary weatherproofing is used to protect exposed structure if the work spans more than a single day.
STEP 04
Structural and covering work
Any structural timber repair or alteration is carried out first, followed by the new covering, felt or membrane, flashing details around chimneys and valleys, and fascias, soffits and guttering.
STEP 05
Inspection and handover
The finished roof is checked from inside the loft and externally before the scaffold comes down. Where the roof forms part of a structural alteration, building control sign-off applies as with any other structural stage.
In detail
What our roofing work covers
Roofing spans several distinct types of work, each with its own materials and methods. The sections below cover what we do and how we approach the different situations you might be dealing with.
Pitched roofing materials and methods
Pitched roofs are covered in tile or slate depending on the property and what matches the surrounding roofscape. Concrete and clay tiles are common across Buckinghamshire housing, while slate is more often found on period properties where matching the existing material matters for appearance. Underneath the covering, breathable membrane, battens and ventilation are specified to current building practice, which matters particularly on older roofs being re-covered, where the original construction may not have included proper ventilation and can suffer from condensation once upgraded insulation is added underneath.
Flat roofing systems
Flat roofs on garages, extensions and dormers are covered using felt or single-ply membrane systems, chosen based on the exposure, expected foot traffic and budget for the specific roof. Falls are set correctly during construction so water drains to the outlets rather than ponding, which is the single biggest factor in how long a flat roof lasts. We will tell you honestly at survey stage if an existing flat roof's falls are inadequate, since re-covering over a poorly built structure without correcting the falls only repeats the same problem.
Full re-roofing versus repairs
A full re-roof strips the existing covering back to the structure, replaces damaged timbers, upgrades the underlay and ventilation, and re-covers the whole roof. This is usually the right approach once a roof is reaching the end of its working life or has multiple problem areas. A targeted repair — replacing a section of slipped tiles, re-flashing a chimney, or patching a specific area of flat roof — makes sense when the rest of the roof is sound and the problem is localised. Our survey identifies honestly which situation you are in rather than defaulting to the larger job.
Roofing as part of extensions, loft conversions and new builds
New roof structures form part of most extension, new-build and loft conversion projects, and are built by the same team carrying out the rest of the structural work. Dormers for loft conversions require the roof to be opened up and a new structural opening formed, which is designed with our structural engineer and taken through building control alongside the rest of the loft conversion works. This integration avoids the handover gap that comes from bringing in a completely separate roofing contractor partway through a bigger project.
Fascias, soffits and guttering
The trim and drainage around the roofline are as important to keeping water away from the building as the roof covering itself. We replace fascias, soffits and guttering as part of a re-roof, or as a standalone job where the roof covering itself is sound but the trim has failed. uPVC is the most common choice for durability and low maintenance, though timber is sometimes matched on period properties where appearance matters more than maintenance-free convenience.

Before you commit
Roofing — your questions answered
Straight answers, so you know exactly how we work before picking up the phone.
- How much does a new roof cost?
- Roofing is priced individually after a free survey, since cost depends on roof size, pitch, covering material and the condition of the existing structure. You receive a fixed price for the agreed scope before any work starts.
- How long does a re-roof take?
- It depends on the size and complexity of the roof and the weather at the time. Rather than quote a generic figure, we set out a realistic programme alongside your fixed quote once the survey has established the scope.
- Can you repair just one section of my roof?
- Yes, where the rest of the roof is structurally sound. The survey establishes whether a targeted repair is appropriate or whether the wider roof condition means a full re-roof is the more sensible option, and we will tell you honestly which situation applies.
- Do you do flat roofing as well as pitched?
- Yes. We carry out flat roofing using felt and single-ply membrane systems, as well as pitched tile and slate roofing, so mixed roofscapes on a single property can be handled by one contractor.
- Do you offer a guarantee on roofing work?
- We do not provide a formal written or insurance-backed guarantee. If a problem arises with the roofing work after completion, Tom comes back and puts it right.
- How long should a new roof last?
- Lifespan depends heavily on the covering material chosen, the quality of the underlying construction and ongoing exposure. We discuss expected durability honestly for your specific roof at survey stage rather than quoting a blanket figure.
- How quickly can you get to a leaking roof?
- We do not offer 24/7 emergency call-out, but we aim to arrange a survey promptly where there is an active leak, so we can assess and quote the repair as quickly as our schedule allows.
- Are you insured for roofing work?
- Yes. DBD Builders Ltd carries £2,000,000 public liability cover and £10,000,000 employers' liability cover, and roofing work is carried out with proper scaffolding and edge protection in place.
- Do you carry out roofing work for structural alterations like dormers?
- Yes. Structural roof alterations for dormers and loft conversions are designed with the structural engineer we work alongside and go through building control at each stage through to sign-off.
- Do you cover roofing across all of Buckinghamshire?
- Yes. Alongside Aylesbury, we carry out roofing work across High Wycombe, Amersham, Beaconsfield, Chesham, Tring, Wendover, Princes Risborough, Great Missenden, Marlow, Gerrards Cross and Leighton Buzzard.
