Roof leak investigation in Sawbridgeworth: what you get
Our job is to find the likely source and tell you. You get a written report with photos showing the likely entry point and the route the water is taking, and recommends what should be done. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, while the repair is a separate matter. Common reasons to book are staining around the chimney inside and staining where a gutter or parapet meets the wall, across the roof space, flat roof details and valleys and parapet gutters.
Chimney stacks on older houses around places like Sawbridgeworth can let water in, at the flashings, the pointing or the mortar round the pots. Damp on a chimney breast isn’t always rain from above, which is why it is worth tracing properly. It is worth looking at the stack from outside and at the timbers beside it in the loft.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Honest limits
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Defects hidden under coverings or inside walls without opening up
- Plumbing leaks that look like roof leaks
- Carrying out the fix
If in doubt, call 07833 053749 or use the contact form and we will recommend the right survey before you book. What a survey covers and doesn’t.
What this survey covers
- Slate and tile slopes
- Lead flashings
- The roof space
- Chimney stacks
- Flat roof details
- Valleys and parapet gutters
- Rooflights and dormers
What happens if roof problems are left?
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. Blocked gutters on homes around Sawbridgeworth overflow and soak walls, particularly where trees overhang. It’s easy to sort the cause early and slow to dry a damp wall.
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all inc. VAT. Size, height and access can affect the price too.

Wind, rain and roofs in Sawbridgeworth
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Different coverings let water in at different points, which shapes where the search starts. Historic houses like Much Hadham Palace, about 4.4 miles north-west, show how far back building in the area around Sawbridgeworth goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
For site and facilities teams at buildings like Fawbert and Barnard Infants' School, tracing a leak on a big roof starts with where the water appears and works back. Homes near green spaces like Gibberd Garden can get more leaves in their gutters in autumn, and an overflowing gutter soon means a wet wall.

Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when booking.

What does a roof survey cost?
Our price is from £150, including VAT. You will know the price for your survey before booking, based on the roof’s size, access and package. To get a price, phone 07833 053749 or email us.
Is thermal imaging part of a leak investigation?
Where conditions suit, it can. It works best after a sunny day, with a dry roof surface and little wind. Wet insulation holds heat longer than dry, which can show up on the image. We always check what it shows with moisture readings.
Tips that help
Nothing here needs a ladder. A few suggestions:
- Let us know if there are tanks or pipes in the loft
- Keep water away from lights and sockets
- Let us know what has already been tried
- Leave roof access to professionals
Once the work is done, hold on to the report. If the leak returns, it is a useful record of what was found, which makes the next step quicker.
Have flashings and flat roofs looked at every few years. They’re where most leaks start, and catching wear early keeps water out.
How the survey works
We check the roof from outside and, where it is relevant and there is safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit normally takes about 1–2 hours for a house, and about three to four hours for a commercial roof. For a survey in Sawbridgeworth, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- We inspect inside and out, starting from the stain.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Before we arrive

What else we do in Sawbridgeworth
Do you need a roof leak investigation in Sawbridgeworth?
A chimney stack has lots of places for rain to get in. Water can enter through crumbling mortar, cracked flaunching, worn flashings or uncapped pots. It can show up on the chimney breast, nearby ceilings or in the loft space.
Signs worth acting on include:
- Water dripping from rafters or underlay
- Leaks at a dormer or roof window
- Leaks that appear only in driving rain
- Staining where a gutter or parapet meets the wall
The streets around a church such as Sawbridgeworth Congregational Church are frequently among the oldest in a place, and if your home is one of the older ones nearby, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
