Common questions in Hammerwood
Do you cover Hammerwood?
We do. The survey and report are the same in Hammerwood as anywhere else.
How do I find out if my home in Hammerwood is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
What’s in the report?
It explains what we saw, what it means and what we’d suggest, backed by photographs. It also says if any part of the roof couldn’t be seen safely.
Will you check the loft?
If it’s needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement.
What’s the price of ELD?
We quote for each roof individually. Tell us about the roof and where it leaks, and call 07833 053749 or drop us an email for a quote.
What happens after the survey?
The report comes by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Does this replace a RICS home survey?
No. It’s a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Electronic leak detection in Hammerwood: what you get
A leak in a flat roof often shows up a long way from where the water gets in. That makes leaks hard to trace by eye. Electronic leak detection tests the membrane itself and locates the breach. It’s testing only, and the repair is for your roofer. On a suitable roof, it takes the guesswork out of finding the hole. The results then follow in a written report with photos. We survey roof terraces and balconies, liquid-applied waterproofing and green roofs, and common reasons people get in touch are repairs that haven’t stopped the leak and a flat roof leak that can’t be traced.
Somewhere as small as Hammerwood, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them as you book.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

What we do, step by step
It is useful to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take a time that depends on the size of the roof and how it’s built, which we’ll explain when we quote. Somewhere as small as Hammerwood, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Point out any leaks or damp patches
- Keep pets inside or away from the areas we’re looking at
- Mention any parking restrictions on your street
How to book
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply ring 07833 053749 or email us whenever suits you.

Electronic leak detection in Hammerwood: local notes
Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. Some old buildings in Sussex have Horsham stone slab roofs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. With Hammerwood Park about 0.8 miles south-east, Hammerwood sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
For site and facilities teams at buildings such as Sackville School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Take an older house close to Church of St Stephen: flat-roofed rear additions and dormers added over the years are worth checking. If you let a flat or house near Dormans station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Hammerwood is about 3 miles east of East Grinstead, in West Sussex. From houses to flats and shops in Hammerwood, the roof can be surveyed on a weekday or at the weekend. Across West Sussex, we cover Hammerwood and the places around it. Crawley is in our area too.

What affects the price in Hammerwood
A few things affect what a survey costs:
- Roof area
- The height of the building and how the roof can be seen safely
- The type of building, from a house to a block or an office
- Features like valleys, chimneys, dormers and parapets
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Booking your survey
You don’t need to know any roofing terms. Just tell us:
- Dates you’re working to, such as exchange
- Why you want a survey: buying, a leak, a storm or new work
- Any photos you have, taken from ground level or a window
- The kind of building and roof involved
We confirm the price for your roof before you book, so you know where you stand. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, ring 07833 053749 or send us an email.
Why it’s worth a survey now in Hammerwood
Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. In a small place like Hammerwood, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.

- Photographs and a written report every time

Useful tips for Hammerwood property owners
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Find the breach before more patching
- Test new membranes before covering them
- Keep a note of leaks after rain
- Keep outlets clear of debris
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.
