Grade II* Listed Roof Replacement, Lonsdale Square
Natural Welsh slate, leadwork, insulation and structural repairs coordinated around a listed London terrace.

Roof repairs, re-roofing, leadwork, flat roofing and roof refurbishment planned around the property, its occupants and the quality of finish the building requires.
Specialist residential roofing contractors
ER Group London undertakes roof repairs, re-roofing, flat roofing, specialist leadwork and roof refurbishment for private homes across West London, Surrey and Elmbridge.
Our work is particularly suited to period houses, listed and conservation-area properties, substantial private homes and architect-led residential projects where access, protection, materials and visible detailing need careful thought.
A good roofing scope starts with understanding the defect. Water ingress may come from the main roof covering, but it can also begin at valleys, abutments, chimneys, parapets, rooflights, outlets, guttering or the junction between pitched and flat roof areas.
Where an architect, surveyor, designer, estate manager or property professional is involved, we can work from drawings, reports, schedules and site information so the roofing package remains aligned with the wider project.

Our Work
Selected roofing projects showing repair, renewal, access, protection and detailing across private homes, listed buildings and roof-terrace work.
Natural Welsh slate, leadwork, insulation and structural repairs coordinated around a listed London terrace.
A pitched roof area converted into a finished roof terrace with access, decking and glass guarding.
A leaking asphalt roof rebuilt as an insulated EPDM roof terrace with walk-on rooflights and decking.
A slate roof renewal where opening-up identified additional structural repairs before completion.
Repair of slipped or damaged slate and tiles, failed flashings, valleys, gutters, chimneys, rooflights and vulnerable roof junctions, with the cause reviewed before the repair is agreed.
Roof refurbishment, new roofs and re-roofing for properties where coverings, underlay, battens, insulation, leadwork or drainage details need a coordinated long-term approach.
Repair and renewal of traditional roofs using appropriate slate, clay tile, leadwork and conservation-sensitive detailing for older and protected residential buildings.
Lead flashings, valleys, gutters, abutments, parapets and other weathering details formed and repaired as part of the surrounding roof construction.
Repair what can be retained. Renew what has failed.
Some roofs need a focused repair. Others need planned renewal of coverings, leadwork, insulation or drainage. ER Group London helps define a practical, technically coherent scope and then carries out the agreed work with suitable access, protection and control.
Period, listed and conservation-area homes
Where existing slate, tile or leadwork remains serviceable, it should be identified before a renewal scope assumes full replacement.
New slate, tile, mortar and lead details should be selected with the existing roof, appearance and building fabric in mind.
Valleys, abutments, chimneys, parapets, rooflights and penetrations are often as important to performance as the main covering.
Listed-building conditions, conservation requirements, drawings, surveys and specifications should inform the work where they apply.
Photographs and condition records help distinguish retained fabric from newly exposed defects and support clear decisions if the scope changes.
Sensitive roof areas should be opened in a controlled sequence, with temporary weathering planned around the property and retained fabric.
Working with professional project teams
ER Group London works with architects, building surveyors, designers, estate managers and residential property professionals where roofing needs to align with drawings, specifications, existing fabric, access constraints and the sequence of other trades.
We review the available information, raise clear questions when site conditions change and help keep the roofing package understandable within the wider programme.

The enquiry establishes the property, the symptoms or intended work, access considerations and any drawings, reports or previous repair history.
Recommendations distinguish between local repair, temporary risk reduction, planned refurbishment and full roof renewal.
Work is planned with consideration for interiors, occupants, neighbours, gardens, deliveries and waste movement.
Leadwork, drainage, rooflights, parapets, walls and adjoining roofs are treated as part of the weathering strategy.
Concealed defects and necessary changes are explained clearly rather than absorbed into vague descriptions of extra work.
The completed scope, relevant observations and sensible maintenance priorities can be recorded for future reference.
Insights
Practical guidance for homeowners and professional teams planning roof repairs, refurbishment or conservation-sensitive roofing work.
What to check before work begins, including permissions, existing materials, surveys, roof details, access and protection.
How access, temporary weathering, protection, deliveries and communication can be planned around people and finished spaces.
A practical guide to visible defects, access limitations, drone imagery, concealed conditions and the next steps after inspection.
From first review to handover
Share the property address, the issue or intended work, photographs and any drawings, reports or repair history.
The visible roof condition, access, likely water-entry routes and critical junctions are reviewed at the appropriate level.
The proposal sets out the intended work, assumptions, limitations and any decisions or specialist input still required.
Access, protection, temporary weathering, sequencing and communication are considered before the agreed roofing work proceeds.
The completed work is reviewed, relevant observations are recorded and sensible future maintenance priorities are explained.
