Flat roofs for extensions, garages and outbuildings, including felt and GRP systems. Practical advice on repair or renewal.
Start underneath the covering.
We consider the condition of the deck, the space below and the insulation arrangement alongside the waterproofing. This helps us recommend work that suits the use of the building.
Give rainwater a way out.
Falls, outlets and gutters work together to drain a flat roof. We assess these details with the upstands and junctions, including where the roof meets a wall or rooflight.
Make a sensible repair-or-renew decision.
A sound roof with a local defect may be repairable. Where wear is more widespread, we explain the renewal options and the reasons behind our recommendation.
What to share when you get in touch
Let us know what you have seen, when it started and whether it changes with the weather. Photographs taken safely from the ground can help explain the issue. We can then discuss the right next step for your roof.
