New flat roof build-ups
Flat roof installation should specify the deck, insulation, vapour control, waterproofing system, falls, edge trims, outlets and upstand details before work starts.

Flat Roof Installation
New flat roof installation for extensions, garages, dormers, commercial roofs and planned construction projects.
Extensions, dormers and commercial roofs
New installations need enough detail at abutments, parapets, rooflights and rainwater outlets. These junctions usually decide whether a flat roof performs well over time.
Future maintenance built in
A good installation makes future inspection easier by keeping outlets accessible, avoiding awkward ponding areas and documenting the system used.
Flat roof installation for extensions, garages and dormers
Common searches around flat roof construction details, garage roof types and extension roof types show that new flat roofs need specification before work starts. Falls, outlets, insulation, vapour control and upstands should all be decided early.
Flat roof structure, falls and outlet design
A new installation should move water reliably to outlets and avoid weak edge details. Firrings, gradients, parapets, rooflights and abutments are practical details that affect long-term performance.
Survey-led recommendations
Flat roofing work should start with the roof build-up, falls, drainage and edge details. A targeted survey helps decide whether a local repair, overlay or full replacement is appropriate.
Next steps for flat roof work
After the roof has been assessed, the next step may be a local membrane repair, drainage improvement, planned replacement, maintenance advice or a more detailed flat roof survey.

What is flat roof installation best for?
Flat Roof Installation is suited to new extensions, dormers, garages, commercial roof areas and planned construction where the build-up can be specified from the start. A survey confirms whether the existing deck, falls and drainage can support the recommended approach.
Can a leaking flat roof be repaired?
A leak can often be repaired when the membrane and deck are otherwise sound. Widespread splits, trapped moisture, failed falls or rotten decking may point towards replacement.
What defects should be checked?
The inspection should look for design risks such as poor falls, weak outlet positions, awkward upstands, insufficient ventilation and exposed roof edges, plus hidden moisture where the roof has leaked more than once.
How do you decide between repair and replacement?
The decision depends on the age of the covering, the number of defects, insulation build-up, drainage performance, safe access and whether previous patch repairs have failed.
Which flat roofing system is right?
A new installation can be designed around the preferred system rather than constrained by a failed existing covering. GRP, felt, EPDM and single ply all have useful roles when specified for the roof size, use and detailing.
Do you work on commercial flat roofs?
Yes. Flat roof surveys, repairs, planned replacement and maintenance can support shops, schools, healthcare buildings, local authority property and low-rise commercial units.
