If your existing roof is approaching the end of its serviceable life, Georgian Roofing can provide a detailed roof replacement quote based on the condition of the property, the proposed roofing system and the full scope of work.
We deliver flat and pitched roof replacement projects throughout London and the surrounding areas, working across commercial, residential, education, healthcare and specialist developments. Our quotations clearly explain the proposed roof build-up, associated works and any important assumptions, qualifications or exclusions.
For further information about the circumstances in which complete renewal may be necessary, read our guidance on roof replacement.
When Should a Roof Be Replaced?
Continued repairs can become impractical or uneconomical when a roof has suffered widespread deterioration. Complete roof replacement may be appropriate where there is:
- Persistent or recurring water ingress
- Widespread failure of the existing waterproofing
- Wet or ineffective insulation
- Deterioration of the supporting roof deck
- Inadequate drainage or poorly designed falls
- Defective perimeter details and penetrations
- A requirement to improve thermal or fire performance
- An existing system that has reached the end of its serviceable life
We assess the available information before recommending replacement and will not propose complete renewal where a more proportionate solution is appropriate. Depending on the condition and construction of the roof, options such as a roof overlay or partial strip may also be considered.
What Does a Roof Replacement Quote Include?
Every project is different, but a typical roof replacement quote may include:
- Removal and responsible disposal of the existing roof covering
- Inspection, preparation or renewal of the supporting roof deck
- Vapour-control layers and thermal insulation
- New waterproofing membranes or pitched roof coverings
- Formation or improvement of roof falls
- Outlets, gutters and associated drainage details
- Perimeter upstands and termination details
- Rooflights and service penetrations
- Leadwork, flashings and associated weathering
- Access, edge protection and site-specific logistics
- Testing, quality inspections and certification
- Manufacturer-backed guarantees where applicable
Our quotation will identify the proposed system, scope, quantities, qualifications and exclusions so that the cost can be reviewed properly. When comparing roof replacement quotes, it is important to confirm that each contractor has allowed for the same specification, insulation, access arrangements and associated works.
Flat Roof Replacement
Georgian Roofing installs a comprehensive range of flat roofing and waterproofing systems, including high-performance reinforced bituminous membranes, single-ply membranes, liquid-applied waterproofing, insulated warm roofs and inverted roof systems.
Our capabilities include Bauder reinforced bituminous systems and Bauder single-ply roofing, alongside other appropriate manufacturer-backed solutions.
We also deliver complete systems incorporating green roof systems, blue roof drainage, photovoltaic installations, roof terraces and podium finishes. These elements are coordinated with the waterproofing design to create a compatible and properly detailed roof build-up.
As a Bauder Approved Contractor, we can deliver manufacturer-backed roofing systems with technical support available from design through to project completion.
Pitched Roof Replacement
Our pitched roof replacement services include Welsh and Spanish natural slate, fibre cement slates, clay tiles and concrete tiles. We can also undertake the associated underlay, battens, ventilation, insulation, ridges, hips, valleys, fascias, soffits and rainwater goods.
More information about the available materials and services can be found on our slate roof repair and replacement page.
For refurbishment and heritage projects, we carefully consider the character of the building and can source materials that complement or match the existing roof where appropriate. We also undertake associated lead roof and traditional leadwork installations.
Surveys and Technical Assessment
An accurate roof replacement quote depends on having sufficient information about the existing building and proposed works. Depending on the project, we may review drawings, specifications, photographs and existing survey information or arrange a site inspection.
Where the existing construction is concealed or its condition cannot be established visually, further investigation may be recommended before the quotation is finalised. This could include a roof defect inspection, core sampling, moisture testing, thermographic surveying or electronic integrity testing, where appropriate.
This process helps establish:
- The type and condition of the existing roof covering
- Whether insulation or the supporting deck has been affected
- The likely cause and extent of any defects
- The suitability of the roof for overlay or complete replacement
- The thermal, drainage and fire-performance requirements
- Any access, logistical or sequencing constraints
