Is Velux Repairs the Right Fix?
A flat roof problem usually shows as a damp patch on the ceiling below, ponding water that never drains, or a felt surface that has blistered, split or lifted at the edges.
- Damp patch on the ceiling directly under a flat roof
- Water pooling and not draining within 48 hours
- Felt blistered, cracked or lifting at the upstands
- Soft or springy feel underfoot indicating deck rot
- Repeated patch repairs to an ageing felt roof
When it is not the answer: If the deck is sound and only a seam has failed, a targeted repair may hold rather than a full re-cover Read the full guide.
Local Factors in Havant
Slightly inland but still salt-exposed; Leigh Park's 1950s–60s fixings have reached end of life across whole streets. Havant and the vast Leigh Park estate mix town-centre stock with England's largest post-war estate — open access, endemic nail sickness. It is why we specify marine-grade fixings and correct lead codes as standard on Havant roofs — the coastal environment punishes anything less.
What to Expect: Velux Repairs in Havant
1. Survey
We assess the covering and, critically, the deck condition underneath — the biggest cost variable on a Portsmouth flat roof.
2. Written quote
An itemised quote specifying the system — GRP, EPDM or felt — and any deck replacement, priced upfront.
3. Scheduling
We book the work and arrange access; most flat roofs are a one to three day job.
4. The work
Strip, assess and replace any rotten deck, then lay the chosen coastal-grade membrane with proper upstands and drainage falls.
5. Cleanup & sign-off
Site cleared, waste removed, and your 10-year workmanship guarantee issued alongside the membrane manufacturer warranty.
Typical Timescales
| Job | Typical duration |
|---|---|
| Small flat roof / porch | 1 day |
| Garage-sized GRP or EPDM | 1–2 days |
| Large or multi-level flat roof | 2–4 days |
| Deck replacement (add-on) | +1 day |
| Dormer flat roof | 1–2 days |
GRP needs dry, workable temperatures to cure — we schedule around the forecast and never lay over a damp deck.
Getting Safely onto Havant Roofs
Most flat roofs work from towers or a small scaffold; access is straightforward on single-storey extensions and garages. Scaffold is specified for: first-floor and above flat roofs, or where edge protection is needed for safe working - always itemised in your written quote, never a hidden extra, and we arrange it.
Havant and the vast Leigh Park estate mix town-centre stock with England's largest post-war estate — open access, endemic nail sickness. Pavement scaffold and skip permits go through Havant Borough Council; allow a few working days on streets like West Street, North Street, Market Parade where space is tight.

Your Guarantee, Explained
The flat roof carries a 10-year workmanship guarantee; GRP and EPDM membranes carry manufacturer warranties of 20–25 years on top.
- Covered: workmanship for 10 years, in writing, transferable if you sell.
- On top: manufacturer warranties on materials (terms vary by product).
- Not covered: storm or impact damage - that is an insurance matter, and we will document it for your claim.
If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.
Living Around the Work
One to three days of work over a single roof area, minimal internal disruption — we protect the space below and clear all waste. You do not need to stay home for external work - we just need power and access agreed in advance.
EPDM can be laid in most conditions; GRP needs dry weather to cure properly, which we plan around Portsmouth's coastal forecast. Slightly inland but still salt-exposed; Leigh Park's 1950s–60s fixings have reached end of life across whole streets.
