How a roof leak investigation works in Pin Green
Older homes have more places for water to get in. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. If your home has a butterfly roof, the central valley gutter is a common culprit in heavy rain. Parapet walls and their gutters are checked from wherever it is safe. The findings are recorded with photos. Typical surveys look at stains around a skylight and damp on a chimney breast, across chimney stacks, lead flashings and flat roof details.
Chimney stacks on older houses around places like Pin Green can let water in, through worn flaunching, failed pointing or lifted flashings. Damp on a chimney breast is not always rain from above, which is why it is worth tracing properly. It’s worth looking at the stack from outside and at the timbers beside it in the loft.
After the visit, you get a written report with photos, sent by email. It explains the condition of the leaking roof, the defects we found and what we recommend.

How we price roof leak investigations
Not every roof costs the same to survey, and it comes down to:
- Extra roofs, like extensions, dormers or garages
- How complicated the roof is, with its valleys, chimneys and parapets
- The package you choose: Basic, Standard or Premium
- Whether thermal imaging or a drone is needed
Every price we give includes VAT. Our price is from £150, including VAT. You’ll know the price for the job before you book.

When to book a survey in Pin Green
Many leaks begin at a flashing. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. Once that seal cracks or lifts, water gets behind it.
Problems we come across often include:
- Stains around a skylight
- Damp underlay across a wide area
- Water through the ceiling under a flat roof
- A leak that comes and goes with the weather
Anyone responsible for a site like Trotts Hill Primary and Nursery School will know that tracing a leak on a big roof starts with where the water appears and works back.
Questions to ask before booking
- What follow-up you get after the report
- Is VAT included in the price?
- What’s outside the scope of the survey
- Their insurance cover
How the survey works
Before we start, let us know why you’ve booked: 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 an hour or two, more where the leak is intermittent or the roof is large. With a bit of garden around a house, as there often is around Pin Green, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. The loft, where there’s safe access, completes the picture.
- You tell us where the water shows and when it appears.
- We look at the stain, the ceiling and the loft above it.
- Outside, we check every likely route in.
- We use moisture detection, and thermal imaging where it is useful.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
How to prepare
- Let us know about parking near the property
- If you are buying, check with the agent that we can get in
- Have any questions written down, so nothing gets missed

Related advice
What we look for on each type of roof
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. When one blocks, water ponds and finds any weak spot. Outlets and the area around them are checked.
Parapet and box gutters
A butterfly roof drains to a central valley gutter. Problems there often show in the rooms on the top floor.
What you can safely check yourself
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can point to a blockage or a sagging run.
Pin Green: your questions answered
Do you cover smaller places like Pin Green?
Yes, Pin Green is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Is my home in Pin Green listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Will you definitely find the leak?
Not always, and we’ll be honest about that. Some leaks hide well, particularly those that need wind-driven rain. Where the source isn’t certain, we list the likely routes in order.
Do you climb onto every roof?
Only where it is safe to do so. We inspect everything that’s safely in view: from ground level, from windows, from inside the roof space, from the roof where it is safe and by drone where it applies. The report says if anything couldn’t be seen.
Can you survey at the weekend?
We carry out surveys on any day of the week. To arrange a date, phone 07833 053749 or drop us an email.
Will you fly a drone over my roof?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Is it a structural engineer’s report?
No. We’re roof surveyors, not structural engineers. If we see signs that need an engineer’s opinion, we will recommend one.
Roof leak investigations around Pin Green
About 3 miles south-east lies Aston Bury, a reminder of how long the area around Pin Green has been built on. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. The covering and its details give the first clues when tracing where water is coming from.
For an older house near a landmark such as Church of Saint Nicholas, water on an older roof tends to find its way in at the lead, the valleys or the chimney. If you own a rental within reach of Stevenage station, a clear finding on where water gets in helps you brief a roofer straight away.
