Roof leak investigations for homes and businesses in Astwick
We use moisture detection and thermal imaging where they help. Moisture detection confirms where timbers, plaster or insulation are damp. A thermal camera shows patterns of temperature rather than water, so its findings are checked with moisture readings. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. The best thermal results come after a sunny day, with a dry roof and little wind. We survey slate and tile slopes, valleys and parapet gutters and lead flashings, and the problems we’re asked to look at most are brown rings on upstairs ceilings and a leak that comes and goes with the weather.
Being in a small place like Astwick makes no difference to how a leak or storm damage is looked at: the journey and access are just planned ahead of time. Tell us where the water shows, when it appears and anything you’ve noticed outside, plus any earlier repairs. If you have photos of the water coming in, they help as well.
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.

Roof by roof
Lead flashings
Water from a failed flashing can travel down the wall or along a rafter. That is why we check the flashings near a stain, not just the one directly above.
Slate and tile slopes
Cracked mortar lets ridge and hip tiles move. Water then gets in along the top of the roof.
Tips from our surveys
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Some tips:
- Check whether pipes or tanks run near the stain
- Clear the loft hatch so we can get in
- Tell us about any past repairs to the roof
- Note the weather when the leak shows
Standard includes a follow-up consultation to talk the findings through, while Premium includes one in person. You can ask us about anything that is not clear.
Have leaves and moss cleared from gutters, valleys and outlets, especially in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.
How we price roof leak investigations
A few things affect what a survey costs:
- Height and safe access
- How complicated the roof is, with its valleys, chimneys and parapets
- Which survey package you book
- The size of the roof
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. The price is always agreed first.
Helping us price your survey
The more you tell us, the easier it is to price the survey. When you contact us, it helps to mention:
- Whether there’s a loft hatch, a shared roof or tricky access
- Any marks or damp showing indoors
- Where the property is, with the postcode
- Pictures of the roof from a safe spot, if you have them
If you are buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or send us an email when you’re ready.

Honest limits
In fairness, a roof survey has limits:
- Leaks from plumbing, tanks or pipework rather than the roof
- A promise to find every leak on a single visit
- Structural calculations (that is a structural engineer’s job)

Roof leak investigations around Astwick
Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. With Hinxworth Place about 1.7 miles east, Astwick sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
If you own a rental within reach of Arlesey station, tracing a leak quickly matters when a tenant is living with it. Take a building like St Mary's CofE Academy Stotfold: a leak through a large roof is frequently found some distance from where the water shows inside.
Astwick is about 1 mile north of Stotfold, in Hertfordshire. We provide roof leak investigations for householders, landlords and businesses in Astwick and the surrounding area. Astwick is one of the places in Hertfordshire we cover for roof leak investigations. We also survey roofs in Milton Keynes.

We also work in nearby towns such as Stevenage (9 miles south), Hitchin (6 miles south), Letchworth (4 miles south), Letchworth Garden City (4 miles south), Baldock (4 miles south-east) and Benslow (6 miles south).

Signs you need a roof leak investigation in Astwick
Flashings are one of the commonest sources of roof leaks. 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.
It’s worth booking a survey if you’ve seen:
- Brown rings on upstairs ceilings
- Damp on a chimney breast
- Leaks at a dormer or roof window
- Staining where a gutter or parapet meets the wall
Take an older house close to Church of Saint Guthlac: water on an older roof tends to find its way in at the lead, the valleys or the chimney.

Your questions about roof leak investigations in Astwick
Do you carry out roof surveys in Astwick?
Yes. We survey roofs across London and the South East, and Astwick is part of that. You can ring 07833 053749 or email us with the address and some details.
Does a conservation area affect roof work in Astwick?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first, with the freeholder or managing agent. Tell us about it as you book and we will plan the survey around it.
Do you climb onto every roof?
Only when it is safe. Some roofs are too steep or fragile to walk on safely. We use safe viewpoints, the roof space and a drone where applicable, and the report records anything we couldn’t see.
Are you insured?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
Does the report include photos?
Yes. Photos are part of every report, so you can see each point for yourself.
What we do, step by step
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. A typical survey takes between one and two hours, more where the leak is intermittent or the roof is large. Somewhere as small as Astwick, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We start with your notes and photos of the leak.
- Inside, we check the stain and the ceiling around it.
- From the loft space, we trace the water’s route where there is safe access.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Preparing for the visit
- Keep pets out of the way during the survey
- Tell us where we can park nearby
- Buyers: confirm access with the estate agent or seller
