Roofing in London
Roof repairs and replacement, gutters, fascias, flat roofs, leadwork and roof windows.
About our roofing service
Most roof failures we attend started as a small defect that nobody could see from the street: a slipped slate, a cracked cement fillet, a blocked parapet outlet. GEM's roofing teams inspect properly — with access equipment or drone survey where appropriate — and repair the actual defect rather than chasing symptoms through the ceiling below.
We work across the roof types London actually has: pitched slate and tile, flat roofs in felt, GRP and single-ply, mansards, parapets and leadwork on period terraces. Gutter clearance, fascia renewal and roofline maintenance are handled as planned works for subscribers, ideally before autumn rather than after the first storm.
When replacement is genuinely due, we scope, scaffold and programme the work with fixed staged pricing and photographic progress reporting throughout.
Questions we hear about roofing
Can you find a leak that only appears in heavy rain?
Intermittent leaks are usually detailing failures — flashings, junctions or outlets — rather than the roof covering itself. We survey the suspect zone, test where practical and evidence the defect before quoting.
How often should gutters be cleared?
Annually for most properties, twice a year where there are overhanging trees. Subscribers can have this scheduled automatically as planned maintenance.
Do you provide guarantees on new roofs?
Yes — workmanship guarantees on our installations plus the manufacturer warranties on membranes and coverings, all recorded against the property file.
