Colthrop Flat Roof Survey
Find out what’s going on with the flat roof before you decide what to do next. We carry out flat roof surveys in Colthrop.
- A sagging deck under the covering
- Pools of water lying on the roof
- Edge trims that have lifted or split
Flat roof surveys for homes and businesses in Colthrop
Each type of flat roof has its own weak points. Felt can blister and crack, asphalt can craze and split, EPDM seams and laps can lift, and GRP can crack where boards meet or at the trims. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Knowing what you have and how it is doing helps you plan what comes next. We survey upstands and outlets, single-ply membranes and felt flat roofs, and people most often book us about pools of water lying on the roof and cracked or split membrane.
Some older homes in villages like Colthrop are listed or in a conservation area, which can shape what a new flat roof may look like. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can decide what to do next.

Leave it or get it looked at?
Standing water on a flat roof rarely sorts itself out. It normally points to an outlet, the falls or a sagging deck, and every wet spell adds to the wear. Finding the cause now keeps more options open. Where a roof is exposed, as many are in small places like Colthrop, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.

Local flat roofs in Colthrop
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. With Shaw House about 3.5 miles west, Colthrop sits in an area with a long building history. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
If your home is one of the older ones in the streets near St Mary's Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Anyone responsible for a site like Francis Baily Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Colthrop is about 1 mile east of Thatcham, in West Berkshire. Colthrop gets the same service as everywhere else we work: a careful inspection, photographs and a written report.

Landmarks near Colthrop
Typical jobs here are in homes near The Swan pub and Kennet School and the streets around them. The closest station to Colthrop is Thatcham station, about 0.5 miles south-west of the centre. A little further out are Old Chapel Textile Centre (2.6 miles south-west) and Donnington Castle (4.6 miles west). Not far away are Thatcham Reed Beds.
What a survey costs
Prices vary from roof to roof, for these reasons:
- How big the roof is
- If the survey needs thermal imaging or a drone
- Chimneys, valleys, parapets and other details
- Extensions, dormers and garages with roofs of their own
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, all including VAT. What your roof costs depends on its size, access and what you want to find out.
Booking your survey
The more you tell us, the easier it is to price the survey. When you get in touch, it’s useful to mention:
- The style of property, from a terrace to a block
- Anything about access we should know
- The address and postcode of the property
- Any photos you have, taken from the ground or a window
Most bookings start with a short call: call 07833 053749 or use the contact form and we will ask a few questions about the roof. You will have a price before anything is arranged.
Do you need a flat roof survey in Colthrop?
No flat roof covering lasts for ever. Around 15 to 20 years is common for felt, while EPDM frequently lasts 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. A survey shows how yours is holding up, whatever its age.
Look out for signs like these:
- Water getting in at rooflights
- Edge trims that have lifted or split
- Splits, cracks and crazing
- Blisters and bubbles in the covering
Landlords with a home close to Thatcham station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before you book
- Whether VAT is added on top
- How long the report takes to arrive
- What they won’t be able to tell you
- Will they check the loft as well as the outside?
How the survey works
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take an hour or two at a typical home, rising to roughly 3–4 hours on a commercial building. Older roofs in small places like Colthrop can have low, tight loft spaces, so tell us about the loft hatch and any ladder. We only go where it’s safe.
- We start with the address and, on larger roofs, the roof area and access.
- We check the rooms or spaces under the roof for staining where there is access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before the survey
- Leave a clear route to the loft
- Make sure pets are kept safely away
- Jot down any questions you want answered

Common questions in Colthrop
Do you cover Colthrop?
Yes. We work right across London and South East England, and Colthrop is part of that. You can phone 07833 053749 or use the contact form with the address and a few details, and we will talk through which survey suits.
How do I find out if my home in Colthrop is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Are you structural engineers?
No. Our survey isn’t a structural engineer’s report, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
What types of flat roof do you survey?
Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. If you do not know what your roof is, we’ll identify it on the day.
How do I arrange a flat roof survey in Colthrop?
To arrange a survey, phone 07833 053749 or use the contact form and tell us the address and what you’d like to know. We will confirm the price and find a day that suits.
Do you go up onto the roof?
We inspect from wherever is safe: on the roof where it’s safe, and from windows, nearby vantage points and inside. Fragile rooflights and fragile sheets are never walked on.
Will I get photos?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
What a flat roof survey does not cover
We only report whatever is safely visible on the day, so some things are outside what a survey can do:
- Parts of the roof that aren’t safe to walk on or view
- An exact number of years the roof has left
- Testing older roof sheets for asbestos
If in doubt, ring 07833 053749 or email us and we will suggest the right survey. What a survey covers and does not.
