Question 1

How long does an EPDM roof last on a North Feltham extension?

Accepted Answer

25–40 years is the honest range. On a well-detailed TW14 install the membrane itself typically outlives the trims, which are the first thing to need attention around year 20.

Question 2

Can you fit EPDM without removing the old felt in North Feltham?

Accepted Answer

Only if the felt is fully bonded, dry and flat. On most TW14 strips we lift the old cover — otherwise the EPDM inherits the felt's bond failures.

Question 3

Do you install EPDM in one piece for North Feltham garage roofs?

Accepted Answer

Yes — for anything up to about 50 m² it's one sheet, no joins. That's why we prefer EPDM over lapped felt on garage roofs across TW14.

Question 4

Is EPDM warmer than a felt flat roof?

Accepted Answer

The membrane is similar; the warmth comes from the insulation build-up beneath. On North Feltham extensions we typically use 100–120mm PIR to hit current U-values.

Question 5

How disruptive is an EPDM install in North Feltham?

Accepted Answer

Most TW14 domestic jobs are 1–3 days: strip day, deck-check and dry-in day, membrane and trims day. No noise, no torch, no smell.
