Roof leak investigation in Blackstone, West Sussex
Tracing where water is getting into your roof for Blackstone and the rest of West Sussex. We survey on any day of the week.
- Water through the ceiling under a flat roof
- Wet patches high on an inside wall
- Drips in the loft during heavy rain
What we are asked to look at in Blackstone
Blocked gutters can look like a roof leak. Hidden gutters behind parapets cause the most trouble, since a blocked outlet sends water over the lining and into the building.
Common reasons to book include:
- Condensation that looks like a leak
- Drips in the loft during heavy rain
- Leaks that appear only in driving rain
- Water coming in around a roof light or dormer
For an older house near a landmark such as The Parish Church of St Bartholomew, old mortar, worn lead and slipped slates are the usual suspects when water gets in.

Roof leak investigation in Blackstone
On older houses, leaks frequently start at lead work and hidden gutters. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. A central valley gutter on a butterfly roof often turns out to be the source in heavy rain. We check parapets, valleys and flashings from each safe vantage point. Our report shows what we found, with photos. We are often asked to look into drips in the loft during heavy rain and water coming in around a roof light or dormer, across slate and tile slopes, the roof space and valleys and parapet gutters.
Being in a small place like Blackstone makes no difference to how a leak or storm damage is looked at: the journey and access are just planned beforehand. Let us know where the water shows, when it appears and anything you’ve noticed outside, along with any repairs done before. If you have photos of the water coming in, they help as well.
After the visit, you get a written report with photos, emailed to you. It sets out the condition of the leaking roof, any defects and our written recommendations.

Wind, rain and roofs in Blackstone
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. A few old Sussex buildings still carry heavy Horsham stone slabs. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand.
If you own a rental within reach of Hassocks station, a clear finding on where water gets in helps you brief a roofer right away.

Practical tips
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Leave roof access to professionals
- Put a bucket under the drip and move valuables
- Mention any plumbing above the damp area
- Take dated photos of the leak
Keep the report after the work is done. If water appears again, it shows what was found before.
After a storm, check the roof from the garden and the street. Pieces of slate or tile in the garden mean something has moved. Prompt repairs stop gaps turning into leaks.
Why act early in Blackstone
Lingering damp encourages mould on ceilings and walls. It is unpleasant, and it is harder to deal with once established. Stopping the water is the first step. For an older or listed building in a place like Blackstone, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.
Every price we give includes VAT, and the report is not charged as an extra. Roof leak investigation starts from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

FAQs for Blackstone
Will you come out to Blackstone?
Yes. Blackstone is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when booking.
Do you carry out roof surveys in Blackstone?
We do. The survey and report are the same in Blackstone as anywhere else.
Is thermal imaging part of a leak investigation?
Thermal imaging is used where it is useful, and it’s part of the Premium Survey. It shows temperature differences, not water itself, so anything it suggests is checked with moisture readings.
Do you take photos of the roof?
Yes. Photos are part of every report.
Does the investigation include the repair?
This service finds and reports the cause, and the repair is separate. With the report, a roofer knows exactly where to look.
What happens next?
You receive the written report by email, with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
How experienced are you?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys across London and South East England.
How the survey works
It is useful to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. Most visits take roughly 1–2 hours, more where the leak is intermittent or the roof is large. Around Blackstone, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We start with what you’ve seen: where the stain is and when it gets worse.
- The visit starts indoors, at the stain and in the loft.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- Moisture readings and thermal imaging are used where they help.
- We email a report with photos, the likely entry point and recommendations.
Getting ready for the survey
- If you’re buying, let the agent know when we’re coming
- Gather any invoices or paperwork from past roof work
- If the roof is shared, arrange access with whoever manages the building
Book a survey
Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To get started, phone 07833 053749 or use the contact form.
