Start with the deck and drainage
A flat roof needs a sound deck, correctly formed falls and clear outlets. A new covering over a weak base leaves the real problem underneath. Your survey checks the existing roof, edges, wall junctions and the route rainwater takes off the roof.
EPDM, GRP or felt
EPDM is a rubber membrane. GRP uses a reinforced fibreglass system. Felt uses bonded layers with sealed laps. We explain the covering and roof details in your quote, including the treatment around rooflights, pipes and adjoining walls.
Details around the edges matter
The upstand at the wall, rooflight kerb and drip edge all need to work with the main covering. Our gallery shows an extension roof with a lantern, new decking and completed felt roofs. These are our own job photographs.
