Can you overlay an existing flat roof on a Lincoln extension?
Sometimes — but only when the deck is genuinely sound. We inspect the substrate first before recommending overlay vs. full strip on any Lincoln property.

Frequently asked questions about flat roofing in Lincoln
Which flat roof system suits a Lincoln extension best?
It depends on the deck, falls and budget. We price EPDM, GRP and felt side-by-side for Lincoln homes so you can compare honestly.
How long does a flat roof last in Lincoln?
EPDM and GRP installed properly across Lincoln routinely last 25–30 years; torch-on felt 15–20. The detailing at upstands and outlets matters as much as the material in LN1, LN2, LN5, LN6.
Which flat roof system do you recommend most often in Lincoln?
For domestic extensions across Lincoln, EPDM rubber is our most-recommended system — it copes well with drier than the Pennine side of the county but with sharp eastern winds that can drive rain horizontally into north-facing roof slopes and detailing around upstands is straightforward.
Can a flat roof in Lincoln be insulated at the same time?
Yes — when we strip back a flat roof in LN1, LN2, LN5, LN6 we can upgrade the insulation to current standards, which makes a real difference to the room below.
