EPDM rubber, GRP fibreglass and torch on felt for extensions, dormers, garages and commercial units.
EPDM rubber, GRP fibreglass and torch on felt are three different systems with three different lifespans, and the right one depends on the deck, the falls and how the roof gets used. Fitting the wrong one is the single most common reason a garage or extension roof fails again a few years later. We will tell you which suits your roof and why.
Whatever goes on top only works if the boards underneath are sound and the roof actually drains. We check both before recommending a system.
Old covering off and new decking where the existing has softened. Laying a new membrane over a soft deck is a guaranteed callback.
EPDM rubber in a single sheet with no joins to fail, GRP fibreglass laid wet and cured in place for a hard wearing finish, or torch on felt in layers. Each has its place.
Edge trims, upstands against the wall and the outlet detail are where flat roofs actually leak, so they get the time they deserve.
Before we finish we make sure water runs to the outlet rather than sitting in the middle of it.

Neither, in the abstract. EPDM goes on as one sheet with no joins and copes well with movement. GRP gives a harder surface that suits a roof people walk on, such as a balcony. The roof decides.
A properly fitted EPDM or GRP roof on a sound deck should give you decades rather than years. The old three layer felt roofs people remember failing were a different thing entirely.
A little after heavy rain is normal. Water still sitting there days later means the falls are wrong, and no covering will fix that on its own.
We would rather not. It hides whatever is wrong with the deck and adds weight. Occasionally it is the sensible option, and we will say so if it is.
Yes. Garages, workshops, units and extensions all get the same approach, and we can work around your opening hours where that matters.
