Commercial Roof Repairs
Commercial roof defects at height are an access problem first. We reach the work with rope access and powered access so occupied buildings stay open while leaks, roof lights and associated high-level roof repairs are closed out.
ARRT Group is SafeContractor accredited and can offer an insurance-backed guarantee of up to 20 years on the work.
Commercial roof repairs in London without scaffold shutdowns
ARRT Group delivers access-led commercial roof repairs in London and the South East — leak works, roof lights and high-level roof repairs — using rope or powered access where scaffold would close trading. UK-wide cover applies for planned programmes. Roof scopes sit alongside high-level glazing so envelope defects are closed out by one coordinated commercial team.
ARRT Group delivers commercial roof repairs where specialised access is the constraint: flat and pitched commercial roofs, roof lights and interfaces with glazed envelopes. We survey at close quarters, identify the entry path, and repair using the method that costs the least disruption — not a default scaffold.
This is access-led roof repair for landlords, FM providers and estates teams across London and the South East, not a general domestic roofing service. Where roof works sit alongside glazing or atrium interfaces, one team owns the survey and the fix.
Glazed and part-glazed roofs sit inside this offer: external roof sealing, roof lights and roof lanterns over occupied space. At Alexandra Palace, a Grade II listed London landmark and live events venue, works have included external sealing to the three major glazed roofs — see the Alexandra Palace hub.
Where the roof is awkward to walk or the first need is a condition record, a drone roof survey captures aerial photography that feeds the same high-level repair programme.
For an occupied-building flat-roof leak that needs a fast commercial response — survey, make-safe, permanent repair, not a domestic roof — see emergency flat roof repairs.

Questions we get asked
Are you a general roofing contractor?
No. We are a specialised-access contractor delivering commercial roof repairs at height — the jobs where scaffold would shut the building or blow the budget.
Do you work on live venues and occupied buildings?
Yes. That is the design constraint. Rope access and powered access keep trading space open wherever the method allows. Named example: external roof sealing to the three major glazed roofs at Alexandra Palace, a Grade II listed London landmark and live events venue.
