Codicote Bottom Roof Leak Investigation
Roof leak investigations in Codicote Bottom, with over 20 years’ experience behind it. Every survey ends with a written report and photographs.
- Condensation that looks like a leak
- Stains around a skylight
- Staining around the chimney inside
Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can point to a blockage or a sagging run.
Roof leak investigations for homes and businesses in Codicote Bottom
Some leaks only appear in certain weather. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Telling us when it happens helps a lot and so do photos. Even on a dry day, a leak usually leaves clues: stained timbers, tide marks and damp underlay. Moisture readings show where materials are still wet. Typical surveys look at water through the ceiling under a flat roof and staining where a gutter or parapet meets the wall, across slate and tile slopes, chimney stacks and valleys and parapet gutters.
Many homes in small places like Codicote Bottom face open ground, where storms hit ridges, verges and chimneys hardest. Damp in old stone, brick or timber walls is slow to dry out, which makes finding the cause quickly worthwhile. A record with photographs is useful if you need to show the damage to anyone else.
Where we cannot see part of the leaking roof, the report says so. You’ll know exactly what was inspected and what wasn’t.

Common questions in Codicote Bottom
Is Codicote Bottom within the area you cover?
Yes, we do. We cover the whole of London and South East England, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Codicote Bottom?
Yes, Codicote Bottom is within the area we cover. We work right across London and South East England. Just phone 07833 053749 or drop us an email and let us know about the property, and we’ll talk through which survey suits.
Are you structural engineers?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
What does a roof survey cost?
Roof leak investigation starts from £150, including VAT. The final figure depends on the roof and the package you choose, and it’s agreed before booking.
Do you climb onto every roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and the report notes anything we couldn’t see.
Will you fly a drone over my roof?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules. We are a CAA-registered drone operator.
Why doesn’t the damp patch line up with the hole?
Because water travels. It runs along rafters, battens or underlay before it drips, so the entry point is frequently well away from the mark. That is why we trace the route rather than patching above the stain.
Roof by roof
Lead flashings
Mortar fillets are sometimes used instead of lead. They crack as the roof and wall move, letting rain run behind the joint.
Chimney stacks
Water that gets in at the top can show up lower down. Unused flues with open pots can let rain straight in.
What affects the price in Codicote Bottom
Not every roof costs the same to survey, for these reasons:
- Height and safe access
- How many separate roofs there are, like extensions, dormers and garages
- The size of the roof
- Features like valleys, chimneys, dormers and parapets
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all with VAT included. The roof’s size, height and access matter as well.
Helping us price your survey
We’ll typically ask about:
- The property’s address and postcode
- Anything about access we should know
- Your timetable, like an exchange date
- Pictures from the garden or a window, if you have them
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or email us.
Why it’s worth a survey now in Codicote Bottom
Patching the spot above the stain often doesn’t work. Because water travels, the real entry point may be somewhere else. An investigation finds the likely cause first. Older cottages and farmhouses around Codicote Bottom can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Prices start from £150, including VAT.
Why book with us
- An independent look at the roof
- Every finding written up with photos
- More than 5,000 surveys completed
- Over 20 years’ experience
What we’re asked to look at in Codicote Bottom
A chimney stack has plenty of places for rain to get in. Water can enter through crumbling mortar, cracked flaunching, worn flashings or uncapped pots. The damp may appear on a chimney breast, a ceiling or in the loft.
Things that frequently lead to a survey include:
- Damp underlay across a wide area
- Water coming in around a roof light or dormer
- Damp on a chimney breast
- Leaks that appear only in driving rain
For an older house near a landmark such as Parish Church of St Giles, lead flashings, valleys and old chimneys are typical places for water to get in.

How it works
The aim of the visit is simple: to look at the leaking roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It usually takes roughly 1–2 hours for most houses, while a commercial roof takes nearer three to four hours. For a village or hamlet like Codicote Bottom, the journey is planned beforehand: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it is safe.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- We inspect inside and out, starting from the stain.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before we arrive
- Unlock side gates and any roof access doors
- Let us know about parking before the day
- If the roof is shared, arrange access with whoever manages the building

Advice
Codicote Bottom roofs and the weather
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Different coverings let water in at different points, which shapes where the search starts.
