Roof leak investigations for homes and businesses in Thornwood Common
On older houses, leaks often start at lead work and hidden gutters. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. If your home has a butterfly roof, the central valley gutter is a common culprit in heavy rain. Parapet walls and their gutters are looked at from wherever it’s safe. Our report shows what we found, with photos. Common reasons to book are leaks that appear only in driving rain and wet patches on loft insulation, across lead flashings, rooflights and dormers and the roof space.
Many homes in small places like Thornwood Common face open ground, so storms hit ridges, verges and chimneys hard. 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.
What you get is a clear record of the leaking roof on the day we saw it. It is useful straight away, and a good reference for later.

Can I check my roof myself?
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we look at the roof.
Thornwood Common roofs and the weather
The wider area around Thornwood Common has a long history of building, with Hill Hall about 3.3 miles south. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. In Essex, older buildings are often clay-tiled, many with weatherboarding, and plenty of post-war and modern estates besides. Where water gets in depends a good deal on what the roof is made of and how it is detailed.
For site and facilities teams at buildings such as St John's Church of England Voluntary Controlled School, a leak through a large roof is frequently found some distance from where the water shows inside. If you let a flat or house near Harlow Town station, a clear finding on where water gets in helps you brief a roofer straight away. Homes near green spaces like Thornwood Common Flood Meadow can get more leaves in their gutters in autumn, so outlets and downpipes are worth watching.

Thornwood Common questions
Do you carry out roof surveys in Thornwood Common?
Yes, Thornwood Common is one of the places we work. The survey and report are the same in Thornwood Common as anywhere else.
Is my home in Thornwood Common listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Is thermal imaging part of a leak investigation?
Where conditions suit, it can. The best results come after a sunny day, on a dry roof with 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.
How long will you be at the property?
On site, it typically takes an hour or two for a house, and more on a big or complicated roof. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
How quickly is the report sent?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, tell us as you book.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
What’s the best way to book?
The quickest way is to ring 07833 053749 or drop us an email. Give us the address and some details about the roof, and we will take it from there. We survey on weekdays, Saturdays and Sundays.
Rented homes, blocks and businesses
Landlords, agents and building managers in Thornwood Common and across Essex can book any of our surveys. To discuss a property or a block, call 07833 053749 or send us an email.
Businesses and commercial landlords can book us too. Bigger roofs take more time, so they’re priced to suit.
What a roof leak investigation doesn’t cover
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Defects hidden under coverings or inside walls without opening up
- Leaks from plumbing, tanks or pipework rather than the roof
- An intermittent leak that shows no trace on the day
If in doubt, call 07833 053749 or send us an email and we’ll recommend the right survey before you book. What a survey covers and doesn’t.
What this survey covers
- Lead flashings
- The roof space
- Chimney stacks
- Slate and tile slopes
- Valleys and parapet gutters
- Flat roof details
- Rooflights and dormers
Tips from our surveys
From years of surveys, a few habits stand out:
- Clear the loft hatch so we can get in
- Have an electrician check any wet fittings
- Don’t climb onto the roof to look
- Put a bucket under the drip and move valuables
Keep the report after the work is done. If the leak returns, it’s a useful record of what was found.
Have flashings and flat roofs looked at every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.

Why it is worth a survey now in Thornwood Common
A small drip today can be a bigger leak after the next storm. Each storm can open a gap a little more. An investigation now gives you time to plan the work. Older cottages and farmhouses around Thornwood Common 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 survey, step by step
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, photograph what we find and record our findings for the written report. It typically takes an hour or two at most homes, though large, tall or awkward roofs take more time. Older rural homes like those around Thornwood Common can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from each safe vantage point.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- Check we can get to the back of the property
- If you’re buying, let the agent know when we are coming
- Have any paperwork from past roof work to hand
