How a roof leak investigation works in Hassocks
Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, plus recommendations on what needs attention. It gives any roofer a clear brief. We find and report the source, and the repair itself is a separate job. Common reasons to book are staining where a gutter or parapet meets the wall and water dripping from rafters or underlay, on flat roof details, lead flashings and rooflights and dormers.
Chimney stacks on older houses around places like Hassocks can let water in, through worn flaunching, failed pointing or lifted flashings. Damp in a chimney breast can have more than one cause, so it is not always obvious where it starts. The stack, its flashings and the loft space beside it are all worth checking.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Before and after the survey
From years of surveys, a few habits stand out as worth the effort:
- Clear the loft hatch so we can get in
- Note the weather when the leak shows
- Put a bucket under the drip and move valuables
- Do not touch fittings that water is reaching
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Many leaks start with a blocked outlet. Leave the clearing to someone with the right equipment.
Roof leak investigations in Hassocks: local notes
In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. 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. An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. In either case, a change of roofing material may need consent.
If you let a flat or house near Hassocks station, a tenant living with a leak needs the cause found, not just the stain painted over. If you own one of the older houses in the streets near St Francis of Assisi, old mortar, worn lead and slipped slates are the usual suspects when water gets in.

Prices for roof leak investigations in Hassocks
What a survey costs depends on the time and equipment it needs. That comes down to:
- Building height and the viewpoints available
- The package you choose: Basic, Standard or Premium
- The shape of the roof and its details
- The roof’s overall size
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Roof leak investigation starts from £150, including VAT.
What to tell us when you contact us
A few details help us suggest the right survey and price. When you get in touch, it’s useful to mention:
- Where water is showing inside, if it is
- The reason for the survey, like buying, a leak or storm damage
- The kind of building and roof involved
- Anything about access we should know
Every survey is priced before it’s booked, so you know where you stand. Our price is from £150, including VAT. For a price for your roof, call 07833 053749 or email us.
What we cannot see
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Water from pipes, tanks or heating systems
- Leaks that only appear in weather we cannot recreate
- Faults hidden behind ceilings or boarding

Signs you need a roof leak investigation in Hassocks
Chimneys can let water in by several routes. Water can enter through crumbling mortar, cracked flaunching, worn flashings or uncapped pots. It can show up on the chimney breast, nearby ceilings or in the loft space.
It is worth booking a survey if you’ve seen:
- Damp underlay across a wide area
- Damp ceilings under a flat roof
- Drips in the loft during heavy rain
- Damp patches next to the stack
For site and facilities teams at buildings like Hassocks Infant School, on a building that size, finding the source of a drip means looking well beyond the stain.
What to check before booking
- Whether they hold professional indemnity and public liability insurance
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- When you will get the report
- What happens after the report arrives
How the survey works
Before we start, tell us why you’ve booked: 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 about 1–2 hours for most homes, though a hard-to-trace leak can take longer. For a survey in Hassocks, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.

Before we arrive

Different roofs, different checks
Valleys
A valley leak can appear well away from the valley inside. From inside the loft space, we follow the water’s route back.
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Ageing felt eventually lets water through.
