Expert RooferVerified memberFlat roofs repaired properly or rebuilt from a sound deck.
Flat roofs fail quietly. Water ponds where the fall has gone, the old felt splits at the edges, and by the time a stain appears inside, the deck underneath is often soft. On rear extensions, garages and dormers across Dublin we see the same pattern again and again.
We tell you straight whether a repair will do or the roof needs replacing. When it is time for a new one, our photographs show how we build it: old covering off, new joists where needed, insulation between them, a fresh OSB deck, new timber edges, then the new covering sealed at every upstand and outlet. Felt, fibreglass and EPDM rubber systems are all part of our flat roofing work.
Every flat roof starts with a free, no-obligation quote and ends with a 5-year guarantee on the work.

Before you book
Straight answers about your roof
Repair or replace: how do you decide?
We look at the deck and the covering. If the deck is sound and the covering has life left, we repair. If the deck is soft or the roof is old, we tell you a new roof is the better spend.
Which flat roof systems do you fit?
Felt, fibreglass and EPDM rubber, chosen for the roof and your budget and set out in your quote.
Can you insulate the flat roof while it is open?
Yes. When we rebuild from the joists we fit insulation between them before the new deck goes on.
Is a new flat roof guaranteed?
Yes. Our work carries a 5-year guarantee.
