Pratt's Bottom: your questions answered
Does a conservation area affect roof work in Pratt's Bottom?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Is parking a problem for a survey in Pratt's Bottom?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. That way the visit can be planned around it.
How do I arrange a flat roof survey in Pratt's Bottom?
Simply phone 07833 053749 or send us an email. We will ask a few questions, confirm the price and agree a date, weekday or weekend.
What if it rains on the day?
Light rain does not normally stop a survey, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions are not right we will arrange another day with you.
Can you tell me how long my flat roof will last?
We don’t give a fixed number of years, because so much depends on upkeep, exposure and workmanship. Our report describes the condition and what needs doing, and when.
Do you cover flat roofs on blocks of flats?
Yes. We survey flat roofs on commercial buildings as well as homes. Expect about 3 to 4 hours on site for most commercial roofs, and larger roofs are quoted for their size.
Will you check the loft?
If it’s needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging.
Flat roof survey in Pratt's Bottom: what you get
A Basic Survey, from £150, covers a visual inspection, a condition report, photos and written recommendations. For moisture detection and a structural check, the Standard Survey starts from £250. On a flat roof, moisture readings can help show whether water has got under the covering. Bigger commercial roofs are priced on their size and access. If you’re worried about leaks around rooflights and upstands pulling away from walls, a survey will tell you what’s going on, whatever the roof.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Pratt's Bottom, roof access is agreed with the building manager or owner beforehand. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

What affects the cost of flat roof surveys
Several things affect the price of a survey:
- Which survey package you book
- How tall the building is and how easy the roof is to see
- Extra roofs, like extensions, dormers or garages
- The use of thermal imaging or a drone
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.
Helping us price your survey
You do not need to know any roofing terms. Just tell us:
- How the loft is reached, if there is one
- Where any leaks, stains or damp patches show inside
- Any photos you have, taken from ground level or a window
- The property’s address and postcode
If you are buying, it is useful to book soon after your offer is accepted, so there is time to use the report before exchange. Otherwise, simply call 07833 053749 or use the contact form whenever suits you.
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.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
How the survey works
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit typically takes about one to two hours at most homes, or half a day or so for a commercial building. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, tell us as you book.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We view the roof from the ground, from windows and from the roof where it is safe to do so.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- Where there is safe access, we check the ceilings and spaces below for signs of water.
- The findings are written up with photos and recommendations and emailed to you.
Preparing for the visit
- Let us know about parking near the property
- Clear the way to the loft hatch
- Leave side gates unlocked
Book a survey
Most bookings start with a short call: call 07833 053749 or drop us an email, and we will ask about the building and what you need. You’ll have a price before anything is arranged.

Local flat roofs in Pratt's Bottom
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Down House, about 2.7 miles west, is one of the historic houses in the wider area around Pratt's Bottom. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If you let a flat or house near Knockholt station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For site and facilities teams at buildings such as Pratts Bottom Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. Pratt's Bottom is in London, so parking needs planning: let us know about permits, visitor bays or off-street space when you book.

Why get it checked now?
On a commercial building, a flat roof leak can disrupt tenants, staff and stock. Surveying the roof in good time means work can be planned and budgeted around the business. In a London terrace or conversion, a roof defect rarely stays your problem alone: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Flat roof survey starts from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we will tell you which fits.

What we can’t see

- Areas we can’t see or reach safely, including fragile rooflights and sheeting
- A promise that the roof will not leak in future
- Testing older roof sheets for asbestos
