Roof leak investigations in Worth: 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. Each of these roof types has its own typical places for water to get in. Crawley, which Worth is part of, is one of England’s post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Low pitches let wind-driven rain reach further under the tiles, and flat-roofed garages and porches are common leak points.
Shop and office owners around County Mall may find that finding where water is getting in quickly keeps disruption down. Living close to Worth Park Gardens is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls.
Worth is about 2 miles east of Crawley, in West Sussex. Worth is part of the area we cover as part of our work across London and South East England. Worth is one of the towns and villages in West Sussex where we work for roof leak investigations.
Surveys in RH10 work the same way as everywhere else we cover. You will find streets like Worth Road, Banks Road and Saxon Road, all of which we cover. Nearby, we also carry out roof leak investigations in Pound Hill (1 mile north), Maidenbower (1 mile south), Three Bridges (1 mile north-west), Tilgate (1 mile south-west) and Forge Wood (2 miles north). Further out, we also cover Horsham (8 miles south-west), Haywards Heath (8 miles south), Burgess Hill (11 miles south), East Grinstead (6 miles east), Broadfield (3 miles south-west) and Billingshurst (15 miles south-west).
Local landmarks in Worth
We work in homes and buildings around Oriel High School, Worth Park Gardens and Dem Shish pub, among other places. The closest station to Worth is Three Bridges station, about 0.7 miles north-west of the centre. Well-known places in the area include Crawley Hospital (2.2 miles west) and County Mall (1.6 miles west). Open spaces near Worth include Tilgate Lake.
How a roof leak investigation works in Worth
Some leaks only appear in certain weather. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. Telling us when it happens helps a lot, along with any photos you’ve taken. Even on a dry day, a leak typically leaves clues: stained timbers, tide marks and damp underlay. Moisture detection shows which materials are still damp. Typical surveys look at staining around the chimney inside and ceiling stains that grow after rain, across flat roof details, valleys and parapet gutters and the roof space.
In a smaller place like Worth, some roofs face open ground, where driving rain gets into any gap at a ridge, verge or flashing. If a leak shows only when the wind is in a certain direction, that is a useful clue. Let us know when it happens when you contact us. The gutters on the most exposed side can overflow too.
Nothing in the report is left vague: if work is needed, the report says so clearly, and where it can wait, that is said too.

What happens on the day
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes roughly 1–2 hours at a typical home, with bigger or more complicated roofs taking longer. A visit to Worth is planned like any other: the time, the access and where to park are agreed in advance. Weekday and weekend visits are both possible. Let us know about any garages, outbuildings or extensions you want included.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- We inspect inside and out, starting from the stain.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Preparing for the visit
- If the roof is shared, arrange access with whoever manages the building
- Unlock side gates and any roof access doors
- Clear the way to the loft hatch
How to book
If you are buying, it’s useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or email us whenever suits you.

Why act early in Worth
Guesswork repairs are a common reason leaks keep coming back. The real way in may be a metre or more away. We find the probable source before anyone starts work. In an older home around Worth, water from a roof defect can get into timber and plaster, and that’s a much bigger job than the original defect.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
What you get with us
- We hold a CAA Flyer ID and Operator ID
- Plain-English reports with photos
- More than 5,000 surveys completed

Practical tips
You don’t need to be a roofer to help. What helps most:
- Take dated photos of the leak
- Leave roof access to professionals
- Keep water away from lights and sockets
- Let us know what has already been tried
If there are several possible sources, we list them in order of likelihood. We say which items need prompt attention.
Do not block the vents at the eaves. Air movement keeps condensation down, and condensation is a common false alarm. Check insulation doesn’t block airflow at the eaves.
What we’re asked to look at in Worth
Condensation is often mistaken for a leak. Moist air from bathrooms and kitchens condenses on the cold underside of the roof, particularly in lofts with blocked eaves. Drips from nails and damp underlay are typical signs.
Most people get in touch when they’ve noticed one of these:
- Staining where a gutter or parapet meets the wall
- Damp ceilings under a flat roof
- Water marks that spread in wet weather
- A leak that comes and goes with the weather
Historic houses like Gravetye Manor, about 4.2 miles south-east, show how far back building around Worth goes. Older roofs in the area may have lead flashings, valleys and gutters that have been patched many times.
Questions to ask before you book
- What they will not be able to tell you
- Will they check the loft as well as the outside?
- Is VAT included in the price?
- Which viewpoints they use to see the roof
Honest limits
Every survey has limits, and it is better to know them up front. Keep these in mind:
- A promise to find every leak on a single visit
- What’s under the covering or behind the plaster
- Putting the leak right

What we look for on each type of roof
Valleys
A valley takes the rain from both sides of the roof. Worn or split linings and slipped valley tiles let it under the coverings.
Parapet and box gutters
Some older terraces have a butterfly roof with a valley gutter in the middle. Problems there frequently show in the rooms on the top floor.
Questions from Worth
How do I find out if my home in Worth is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you cover smaller places like Worth?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Why is the stain in a different place from the leak?
Because water travels. It can follow a timber or the underlay a long way first, so the stain may be some distance from where it gets in. That’s why we trace the route rather than patching above the stain.
Will you fix the leak as part of this?
The investigation is about finding the cause. The repair isn’t part of it. You get a report with photos showing where the water is getting in and what needs attention.
How do you tell a leak from condensation?
Condensation can look very like a leak. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We check the pattern of damp and the ventilation, then say which is most likely.
Do you look in the roof space?
If it’s needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement.
Is thermal imaging part of a leak investigation?
It can, when the conditions are right. It works best after a sunny day, with a dry roof surface and little wind. Damp areas can hold heat differently from dry ones. Its findings are confirmed with a moisture check.
