Flat roofs around East Grinstead
East Grinstead has grown in stages, and each stage left its own flat roofs behind. Postwar estates such as those around Imberhorne and Sunnyside have flat roofed garages, porches and single storey rear extensions. Larger Edwardian and Victorian houses towards the south of town often have flat roofed bays, dormers or later kitchen extensions. Many of these roofs were laid as traditional felt on timber decks with little insulation and almost no fall, which is why they pond and fail.
Because the town sits high on the Weald ridge, flat roofs here also see plenty of wind uplift at the edges, and those near mature trees collect leaves and moss that block the outlets.
Which flat roof system suits your property?
| Roof | What we usually recommend | Why |
|---|---|---|
| Single garage | EPDM rubber | Simple shape, one sheet, cost effective |
| Single storey extension | EPDM or GRP | Depends on rooflights, edges and appearance |
| Dormer on a period house | GRP or lead | Neat detailing around cheeks and windows |
| Balcony or roof terrace | GRP with anti slip finish | Designed for foot traffic |
| Large or complex roof | Modern reinforced felt | Handles detail and size well |
We explain the options at the survey and recommend one, with the reasons in writing. For the detail on each, see EPDM rubber roofing and GRP fibreglass roofing.

Repair or replace?
A split or a lifted edge on an otherwise dry, firm roof can usually be repaired. If water ponds across the roof, the deck feels soft from below, or the ceiling has been stained more than once, replacement is normally the better value. We show you photographs from the survey so you can see the evidence for yourself.
Insulation and Building Regulations
If you replace more than half of a flat roof, Building Regulations normally expect the insulation to be upgraded where that is practical. We usually do this with a warm deck: insulation boards on top of the deck with the waterproofing above. It keeps the room warmer and avoids disturbing the ceiling. We check door thresholds and window sills first, because the roof finishes higher than before.
What our flat roof price includes
- Stripping the old roof and any rotten deck boards
- New deck boards where required
- Vapour control layer and insulation with falls built in
- Your chosen waterproofing system
- Edge trims, upstands, flashings and outlets
- Waste removal, before and after photographs and VAT
Conservation areas and listed buildings
Parts of central East Grinstead are within a conservation area, and the town has many listed buildings. Visible changes to flat roofs on these properties, such as new rooflights or a different finish, may need permission. We will flag this at the survey.

Warning signs your East Grinstead flat roof is failing
- Puddles that are still there days after rain
- Moss and leaf litter collecting near the outlet
- Cracks or blisters in old felt
- Lifting trims at the edges
- Damp patches on the ceiling below or on walls under the roof edge
With the woodland and mature gardens around East Grinstead, blocked outlets are one of the most common causes of ponding and leaks we find.

Flat roofs on hilly and exposed sites
East Grinstead stands on high ground, and some homes on its edges are exposed to strong westerly winds. Flat roof edges and trims must be fixed securely so wind cannot get under the membrane. We pay particular attention to perimeter detailing on exposed roofs.
Materials we use
We work with EPDM rubber, GRP fibreglass and built up felt systems, along with insulation boards, vapour control layers, edge trims and lead. See EPDM rubber roofing, GRP fibreglass roofing and our guide how long does a flat roof last.
