FAQs for Windmill Hill
Will you come out to Windmill Hill?
Yes, Windmill Hill is covered. Our area covers London and South East England, and smaller places are part of that. Longer journeys are simply planned beforehand.
Is the coastal weather around Windmill Hill hard on roofs?
Generally, yes: wind and salt air take more of a toll near the sea. Ridges, verges, flashings and fixings are where it usually shows.
Does this replace a RICS home survey?
No. We look at the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Will I get photos?
Yes, every report has them. Pictures sit next to the findings they show, so you can see what we mean.
Why isn’t the leak directly above the stain?
Because water travels. It can follow a timber or the underlay a long way first, so the stain may be some distance from where it gets in. That is why we trace the route rather than patching above the stain.
What’s the best way to book?
It is easiest to call 07833 053749 or send us an email. Tell us the address and a little about the roof, and we will point you to the right survey. Surveys run on weekdays, Saturdays and Sundays.
Will you go up on the roof?
Only when it is safe. Safe viewpoints, the loft space and a drone where it applies cover most of what’s needed.
How a roof leak investigation works in Windmill Hill
The aim is to find where the water is getting in and explain it. You get a written report with photographs showing the likely entry point and the route the water is taking, and recommends what should be done. It gives any roofer a clear brief. The investigation finds and explains the cause, and the repair itself is a separate job. We survey flat roof details, the roof space and rooflights and dormers, and people most often book us about damp ceilings under a flat roof and staining where a gutter or parapet meets the wall.
In a smaller place like Windmill Hill, some roofs face open ground, so wind and driving rain find any weakness in ridges, verges and flashings. A leak that only appears in certain weather frequently points to an exposed detail. It is useful to know when and where the water appears. The gutters on the most exposed side can overflow too.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Useful tips for Windmill Hill property owners
A survey works best with a little help from you, before and after. Tips:
- Take dated photos of the leak
- Mention earlier attempts to fix the leak
- Leave roof access to professionals
- Clear the loft hatch so we can get in
Keep the report after the work is done. If water appears again, it shows what was found before, which makes the next step quicker.
Check the loft after heavy rain, with care and a good torch. Look for drips, damp patches and stains on timbers. Photograph anything new.
What we look for on each type of roof
Chimney stacks
A stack has several possible ways in for rain. Each is looked at from each safe vantage point.
Slate and tile slopes
On slate roofs, corroded nails let slates slip. One slipped slate can be enough to cause a leak, especially in driving rain.
Should I look at the roof myself first?
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking, as it helps us focus the survey.
Roof leak investigations around Windmill Hill
The coast is about 2 miles or less from Windmill Hill, and being near the sea means more wind and salt than a roof inland would face. Wind lifts loose slates, tiles and ridge pieces, and driving rain finds any gap they leave. The wider area around Windmill Hill has a long history of building, with Cobham College about 3.3 miles south. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead.
For hotels and guest houses around Windmill Hill, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do. Anyone responsible for a site like Wrotham Road Primary School will know that tracing a leak on a big roof starts with where the water appears and works back. Take an older house close to Christ Church Milton: the leak may come from a chimney, a valley or tired lead rather than the covering itself.

Leave it or get it looked at?
A small drip today can be a bigger leak after the next storm. Wind lifts loose slates further and gaps widen. Tracing it now lets you plan the work rather than react to it. On a bungalow or cottage around Windmill Hill, the roof sits close to the rooms below, so a small leak can mark a ceiling within a few storms. Finding the cause first saves a second job inside.
