Home › Flat Roof Replacement Lewisham
Complete flat roof replacement in Lewisham using EPDM rubber, GRP fibreglass or high-performance felt — with upgraded insulation, proper falls and long manufacturer-backed life expectancy.
When a flat roof reaches the end of its life, patch repairs become false economy. Our flat roof replacement service in Lewisham strips the old covering back to the deck, replaces any water-damaged timber, corrects the falls so water actually drains, and installs a modern covering with a design life measured in decades — not years.
We install the three leading systems and will recommend the right one for your roof: EPDM rubber for clean, seamless durability; GRP fibreglass for a hard-wearing finish on complex shapes; and modern high-performance felt where budget leads. Replacements can include upgraded insulation to current building regulations, which cuts heat loss through what is often the coldest part of the house.
From terraced back additions to whole-garage roofs across Lewisham, you get a fixed written quote, a tidy site, and a team that turns up when it says it will.
From Victorian terraces in Brockley borders to inter-war semis towards Catford, Lewisham’s mixed housing stock throws up everything from slipped slates to tired concrete tiles. We cover the whole of SE13 with the same fast, tidy service we’re known for west of the river.



It depends on the roof. EPDM suits large simple roofs, GRP suits complex shapes and roofs that get foot traffic, and high-performance felt remains a solid budget option. We’ll recommend honestly rather than pushing one system.
A typical extension or garage roof in Lewisham takes two to four days including any timber work, longer if insulation is being upgraded or the deck needs significant replacement.
Installed properly, EPDM and GRP systems routinely exceed 25 years; high-performance felt around 20. We install to manufacturer specification so the guarantee actually stands.
