Roof leak investigations for homes and businesses in Holmbury St Mary
On a flat roof, water can travel a long way under the covering. Common causes are splits and blisters, tired upstands and outlets that do not drain. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. If you’ve noticed leaks at a dormer or roof window and leaks that appear only in driving rain, a survey will tell you what’s going on, whatever the roof.
For a small place like Holmbury St Mary, the inspection is the same as anywhere: we simply plan the journey and access ahead. Tell us where the water shows, when it appears and anything you’ve noticed outside, along with any repairs done before. Photos of the stain and of the roof from outside are helpful too.
The report doesn’t just list problems. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

What a roof leak investigation looks like in Holmbury St Mary
Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. Polesden Lacey, about 4.8 miles north, is one of the historic houses in the wider area around Holmbury St Mary. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
The streets around a church like St Mary The Virgins Church are often among the oldest in a place, and if yours is one of the older homes nearby, the leak may come from a chimney, a valley or tired lead rather than the covering itself. Landlords with a home close to Gomshall station may find that a clear finding on where water gets in helps you brief a roofer straight away.

Signs you need a roof leak investigation in Holmbury St Mary
Many leaks begin at a flashing. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in.
These are some of the problems a survey can pick up:
- Leaks at a dormer or roof window
- Drips in the loft during heavy rain
- Damp walls below an overflowing gutter
- Leaks below a flat extension roof
Take a building like Belmont Prep School: a leak through a large roof is frequently found some distance from where the water shows inside.
What to check before booking
- Will the report include photos?
- Whether the loft space is looked at, where there is one
- What’s outside the scope of the survey
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
What affects the cost of roof leak investigations
All our prices include VAT. What changes the price is:
- Extra roofs, like extensions, dormers or garages
- The height of the building and how the roof can be seen safely
- House, block, shop or office
- The size of the roof
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, with VAT included. We’ll tell you which package suits the questions you have.
Helping us price your survey
We’ll usually ask about:
- The type of building and roof, like pitched or flat
- Why you want a survey: buying, a leak, a storm or new work
- Access details, such as a loft hatch or a shared roof
- When you need the report by

Common questions in Holmbury St Mary
Do you cover smaller places like Holmbury St Mary?
Yes, Holmbury St Mary is covered. Our area covers London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
How do I find out if my home in Holmbury St Mary is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
How long will you be at the property?
The visit normally takes about 1–2 hours at most homes, and longer for a large or complex roof. We will give you an idea of timing when you book.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. We’ll talk about access when booking.
Can thermal imaging help find my roof leak?
We use thermal imaging where it helps, and it’s part of the Premium Survey. It picks up temperature patterns rather than water, so anything it suggests is checked with moisture readings.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Will you fly a drone over my roof?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.

What happens on the day
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes about 1–2 hours, more where the leak is intermittent or the roof is large. Somewhere as small as Holmbury St Mary, access is frequently the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Getting ready for the survey
- If the roof is shared, arrange access with whoever manages the building
- Check we can get to the back of the property
- Clear the way to the loft hatch

What you can safely check yourself
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book and it will help the survey.
Your own check is a good start, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Surveys for landlords and agents in Holmbury St Mary
Any of our surveys can be booked by landlords, agents and building managers in Holmbury St Mary. To discuss a property or a block, ring 07833 053749 or drop us an email.

- Water from pipes, tanks or heating systems
- Carrying out the fix
