A new roof starts with understanding the structure below it
A new roof creates the weatherproof covering for a new part of your home, such as an extension or garage. Re-roofing usually means removing and renewing the covering on an existing roof, with the supporting layers assessed as work progresses. Neither should be treated as simply choosing a tile colour. The existing structure, pitch, insulation strategy and connections to adjacent walls all influence the right approach.
For a homeowner facing repeated leaks, re-roofing can offer the chance to address several deteriorating components together. It is not automatically the answer to every roof problem, however. An isolated flashing defect on an otherwise sound roof may be better addressed with a repair. We explain why renewal is being considered and what it would include, so the decision reflects the condition rather than the age alone.

Replacing only what is visible can leave important problems untouched
A new covering needs sound support and carefully detailed edges. If a quote ignores the layers beneath the tiles or the way the roof meets walls and gutters, the apparent saving may leave unresolved defects within the finished roof.
Hidden deterioration discovered too late
Old battens, local timber damage and deteriorated underlay may only become fully visible after stripping. Planning for inspection at that stage allows findings to be discussed rather than covering over a problem that the new roof still depends on.
Incompatible material changes
Different coverings can change the load on the structure and the required batten gauge, overlap and fixing arrangement. Choosing a material purely on appearance can overlook whether the existing pitch and structure are suitable for it.
Poorly coordinated insulation and ventilation
Changing the roof build-up can alter how moisture behaves. Insulation placed without attention to ventilation routes or the intended construction can create condensation risks, so these decisions need consideration together.
Common mistakes homeowners make
- Assuming re-roofing always includes replacing the structural roof timbers.
- Selecting a tile or slate before confirming the pitch and structural suitability.
- Comparing replacement quotes that include different access and junction work.
- Leaving insulation and ventilation decisions until the covering is being fitted.
Our 5-Step Process
- 01
Inspect the roof and establish your plans
We assess the existing roof, discuss leaks or deterioration and ask about proposed alterations. The inspection considers shape, covering, accessible supporting areas and practical access, with any limits to what can be seen explained at this stage.
- 02
Set out the specification and quote
We explain the proposed covering, supporting layers and associated junction work. Your fixed written quote identifies the agreed scope. Where structural advice or confirmation of regulatory requirements is needed, this should be resolved before relying on assumptions about the replacement.
- 03
Strip and renew in a planned sequence
The agreed work is organised around access and weather conditions. Once old coverings are removed, exposed supporting components can be assessed. Any unexpected defects affecting the scope are discussed before additional work is agreed, rather than automatically concealed beneath the replacement.
- 04
Verify coverings, junctions and drainage
We check the finished roof details, including the arrangement of coverings, ridges, verges and relevant flashings. Eaves and rainwater routes also need attention, because a new roof must shed water into the intended drainage system rather than simply look complete.
- 05
Handover and guarantee confirmation
We explain the completed work and any relevant maintenance observations. All work comes with a guarantee; we confirm the guarantee for your job in your quote. Keep the agreed scope and guarantee information together for future reference.
What You Get
A coordinated programme from the outset
Deciding on the covering, access and associated details before stripping begins reduces avoidable uncertainty. You can plan around the proposed sequence and understand which stages depend on weather or findings once the roof is open.
Access considered as part of the job
Renewing a roof involves handling materials and working around exposed edges. Suitable access needs to be planned for the property and scope, rather than treated as an optional extra to be improvised after work starts.
A roof build-up considered as a whole
New coverings depend on battens, underlay, fixings and junctions doing their jobs. Looking at those components together gives the replacement a sounder basis than renewing the visible surface while ignoring worn or unsuitable supporting details.
A clearer repair-versus-renewal decision
Replacement is a substantial decision, so it should be supported by an explanation of condition. Comparing the likely extent of recurring repairs with a defined renewal scope helps you decide where your spending is justified.
Consistency across connected details
A new covering should connect properly to valleys, wall abutments, roof openings and gutters. Including these interfaces in the discussion helps you understand which existing components can remain and which need attention alongside the replacement.
Time to decide without a deposit
Our free site inspection and no-obligation quote let you review the proposed work before agreeing to it. No deposit is required. Customers review us 5 stars on Yell, and the guarantee for your job is confirmed in your quote.
What to consider before replacing a residential roof
The useful questions concern more than surface area. A replacement should suit the roof geometry, the building beneath it and any planned improvements, with clear boundaries between covering work and structural alterations.
New construction, re-roofing and structural changes
For a new extension or garage, the roof covering needs coordination with the supporting design and the junction to the existing home. Pitch, spans, openings and drainage routes should be established before materials are ordered. A lower extension roof joining a house wall presents different detailing requirements from a simple detached garage with two clear roof slopes.
On an existing home, re-roofing does not necessarily mean replacing rafters or trusses. Sound structural members may remain while coverings, battens and underlay are renewed. If deterioration, deflection or a proposed loading change raises a structural question, appropriate assessment is needed. A covering replacement should not be described as a structural solution unless that work is actually included and properly considered.
Choosing tiles or slate for the roof you have
Concrete tiles, clay tiles and slate differ in weight, format, appearance and installation requirements. The slope and exposure influence the overlap and fixing specification, while the roof layout affects cutting and detailing around valleys and hips. A material that looks suitable on a neighbouring house may not be appropriate for a shallower extension roof on your property.
Changing covering type also affects how the roof looks at the eaves, ridge and verge. Tile profiles and slate sizes can alter the appearance of a broad roof slope considerably. We discuss these practical choices alongside suitability, rather than treating finish and construction as unrelated decisions. Where planning constraints may apply, establish the position before changing the appearance of the roof.
Underlay, battens, insulation and moisture management
Removing the old covering creates an opportunity to assess the battens and the condition of the roof beneath. New underlay needs appropriate support and detailing, including at the eaves where water must be directed outwards. Battens and fixings must suit the chosen covering. These layers are not decorative extras, even though they disappear from view once the roof is finished.
Insulation and ventilation need to reflect the intended roof construction. Adding insulation can change temperatures and moisture behaviour within the roof space, while blocked air paths can create problems in a ventilated arrangement. Relevant Building Regulations requirements should be checked for the proposed renewal, including thermal performance where applicable. The quote should make clear which insulation or related work is included rather than assuming it is part of every re-roof.
Sequencing, weather exposure and finishing details
A re-roof is planned around the size and complexity of the property, the available access and the forecast. Stripping exposes parts of the building, so the sequence and temporary weather protection need consideration. No contractor can control the weather, and a realistic programme allows for conditions that may make roof work unsuitable or affect the pace of progress.
Completion involves more than reaching the ridge with new tiles. Flashings, valleys, verges, ventilation components and the connection to gutters all influence performance. On homes in Woking, Camberley, Guildford and surrounding Surrey areas, roof forms vary from straightforward bungalow slopes to houses with several extensions. A property-specific inspection is therefore more useful than estimating the whole project from floor area alone.

Frequently Asked Questions
Roof size, shape, height, covering choice, access and the condition of supporting components all affect cost. Valleys, chimneys, roof openings and insulation work can change the scope too. A free inspection gives a fixed written quote for the agreed specification, allowing you to understand what is included rather than relying on an approximate rate.
