We replace and repair flat roofs in EPDM rubber, traditional felt and asphalt. Flat roofs cover extensions, garages, dormers, porches and bay windows, and each one needs a covering that suits how it is built and used.
Flat roofs, asphalt ones especially, are prone to leaking, mainly through poor maintenance, age and years of exposure to the weather. If a leak goes unnoticed, water can soak the decking, the insulation and the woodwork beneath it, and the rot that often follows is expensive to put right. Damp also brings health risks.
Watch for cracks, splits or blisters in the surface, a deck that has started to dip, and stains on the ceiling below. We are happy to come and survey your roof and provide free estimates for all the work we recommend.
EPDM is a synthetic rubber membrane, usually laid as a single sheet so there are few joints for water to find. Modern felt systems are built up in layers and finished with a mineral surface that protects them from sunlight. Asphalt is laid hot and sets into a hard, seamless finish.
Questions about flat roofing
Which is best: EPDM, felt or asphalt?
Each has its place. EPDM is light and flexible and has very few joints, which suits most extensions and garages. Felt is a tried and tested choice that copes well with awkward details. Asphalt is very hard-wearing and is often found on older or larger roofs. We can advise on the right one for yours.
Can a leaking flat roof be repaired, or does it need replacing?
Small splits, blisters and failed joints can often be repaired. If water has got into the deck and it has gone soft or started to sag, the covering and the boards beneath usually need replacing, or the leak will keep coming back.
Why does water sit on my flat roof?
A flat roof needs a slight fall so that rain runs off to the gutter or outlet. Puddles that stay long after rain mean the deck has sagged or the fall was never quite right, and standing water wears the covering out faster. The fall is usually corrected when the roof is replaced.
Can a new flat roof be insulated?
Yes. When a flat roof is replaced, insulation boards can be laid over the deck and under the new covering, which is known as a warm roof. It keeps the room below warmer and reduces the risk of condensation.
