Discuss Your Flat Roof Explore Flat RoofingRepairing, replacing or constructing a flat roof?
Tell us about the property, approximate flat roof size, current condition, London location and whether the roof forms part of an extension or wider refurbishment project.
Consider the complete roof build-up
Flat roofing is more than the visible outer covering. Falls, outlets, junctions, insulation, deck condition and surrounding construction can all affect the final work package.
Discuss your flat roofing project
Provide the main project information below.
Flat roof repair, replacement and refurbishment
Flat roofs are used across London on houses, extensions, garages, commercial buildings and many other property types.
Over time, existing flat roofing can require local repair, refurbishment or more substantial replacement depending on the condition of the roof and surrounding details.
Crestane Construction can coordinate suitable flat roofing projects across London as standalone works or as part of a wider construction package.
New flat roofing can also form part of suitable extension, refurbishment and larger residential or commercial projects.
From local repair to complete flat roof projects
The appropriate work package depends on the existing roof, condition and wider construction requirements.
Flat Roof Repairs
Suitable local repairs to defective areas where a focused repair approach is appropriate.
Flat Roof Replacement
Suitable broader replacement works where the existing roof requires more substantial renewal.
Flat Roof Refurbishment
Coordinate suitable refurbishment around the existing roof and surrounding construction.
Extension Flat Roofs
Coordinate new flat roofing within suitable rear and side-return extension projects.
Garage Flat Roofs
Suitable repair, refurbishment and replacement work to garage flat roofs.
Rooflight Integration
Coordinate suitable rooflight and skylight work within new or refurbished flat roofs.
Roof Junctions
Coordinate suitable detailing where the flat roof meets walls and surrounding construction.
Drainage Details
Consider suitable falls, outlets and drainage arrangements within the roofing package.
Commercial Flat Roofing
Suitable flat roofing within larger commercial refurbishment and construction projects.
The roof covering is only one part of the system
A flat roof also depends on the condition and arrangement of the supporting deck, insulation, falls, outlets, perimeter details and roof junctions.
Where a roof is being replaced or incorporated into new construction, these elements need to work together as a complete roof build-up.
Crestane can coordinate suitable flat roofing alongside the wider construction works around it.
Not every flat roof requires complete replacement
Where an existing roof has a localised defect and the surrounding construction remains suitable, a focused repair may be appropriate.
Where defects are widespread, the roof has deteriorated significantly or wider refurbishment is already planned, a more substantial roofing package may make greater sense.
The appropriate scope depends on the existing roof construction and condition rather than simply the presence of one visible leak.
For general roofing repairs, see our Roof Repairs London service.

Flat roofing for rear and side-return extensions
Flat and low-profile roofs are commonly used on residential extensions throughout London.
Suitable extension roofing may also incorporate rooflights to introduce natural light into new kitchen, dining and living areas below.
Crestane can coordinate suitable roofing together with the structure, glazing, internal finishes and wider extension works.
See our House Extensions London service.
Bring natural light through the roof
Rooflights can form an important part of flat-roofed extension and refurbishment projects.
Their position and surrounding roof detailing need to work with the wider roof construction.
Crestane can coordinate suitable rooflight installation together with the flat roofing and surrounding building works.
See our Roofing, Skylights & Glazing London service.
Flat roofing within suitable commercial projects
Commercial properties can include substantial flat roof areas requiring repair, refurbishment or works associated with wider construction projects.
Crestane can consider suitable commercial flat roofing where it forms part of an appropriate multi-trade construction scope.
The final project requirements depend on the existing building, roofing system, access and extent of work required.
See our Commercial Construction London service.
