Flat roofs on Cambridge extensions
A huge number of Cambridge homes have a flat roof somewhere, usually a 1960s or 1970s rear extension, a dormer, a bay or a garage. The old built-up felt on these tends to blister, split and pond water after 15 to 20 years. When it goes, the leak often shows up well away from the actual fault, which is why a proper survey matters.
EPDM, GRP and felt compared
We work with all the main flat-roof systems and recommend the right one for the job:
| System | Best for | Typical lifespan |
|---|---|---|
| EPDM rubber | extensions and garages, one-piece, few seams | 25 to 30+ years |
| GRP fibreglass | balconies and walk-on roofs, hard-wearing | 20 to 30 years |
| Built-up felt | budget repairs and small areas | 15 to 20 years |
Warm roofs, insulation and Part L
A modern flat roof should be a warm roof, with the insulation above the deck so condensation cannot form underneath. We typically build up the deck, add PIR insulation and finish in EPDM or GRP. Where the work is large enough to fall under Part L, we make sure the insulation meets current standards. The guidance is in Approved Document L. We can also fit triple-glazed roof domes and approved VELUX flat-roof windows to bring in light.
What flat roofing costs in Cambridge
Price comes down to the area, the system and how much of the old deck needs replacing. EPDM on a standard extension is a quick, tidy job; a walk-on balcony in GRP costs more. Your written quote is fixed once we have surveyed it.
"On Cambridge extensions we nearly always specify EPDM. It goes down in one piece with almost no seams, so there is simply less to fail, and it shrugs off our freeze and thaw winters," says the lead roofer at Alpha Roofing.

Trusted across Cambridge
Spotted a leak before the storms hit, called Alpha and they were round the next morning. Tidy, friendly, and a fair price. Wouldn't use anyone else.
Full re-roof on our 1930s semi. The team explained everything, stuck to the quote, and left the garden cleaner than they found it. Genuinely lovely lads.
Had VELUX windows fitted in the loft conversion. Faultless work, no mess, and they sorted everything themselves. Highly recommend to anyone in Cambridge.

Frequently asked questions
How long does an EPDM flat roof last?
A well-fitted EPDM rubber roof lasts 25 to 30 years or more. It goes down in one piece with very few seams, which is why it copes so well with Cambridge winters.
EPDM or GRP fibreglass, which is better?
EPDM is ideal for extensions and garages because it is one continuous sheet. GRP fibreglass is harder-wearing and better for balconies and walk-on roofs. We will recommend the right one for your roof.
Can you fix a leaking flat roof rather than replace it?
Sometimes, if the deck is sound and the fault is local. If the covering is past its life and ponding, a new warm roof is the better spend. We will give you an honest answer after a survey.
How much does a new flat roof cost in Cambridge?
It depends on the size, the system and how much of the deck needs renewing. We give a free, fixed-price quote in writing with no obligation.
