Roof leak investigations for homes and businesses in Sydenham
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that don’t drain. Ponding water makes any weakness worse. We check the roof surface and the ceiling below. Leaks under flat extension, garage and dormer roofs are common. Felt often lasts around 15 to 20 years, so age is part of the picture. Typical surveys look at wet patches on loft insulation and damp ceilings under a flat roof, on valleys and parapet gutters, lead flashings and chimney stacks.
Roofs in small places like Sydenham frequently stand in the open, so storms hit ridges, verges and chimneys hard. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A record with photographs is useful if you need to show the damage to anyone else.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Why act early in Sydenham
Damp in a ceiling or loft can lead to mould. It’s unpleasant, and it’s harder to deal with once established. Stopping the water is the first step. For older village homes like those around Sydenham, the right replacement materials are not always easy to find quickly. That’s one more reason to find defects before they become urgent.
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, from £400 including VAT. We can help you choose the package that fits what you need to know.

What to let us know when you contact us
If you can, have these to hand when you contact us:
- Your timetable, such as an exchange date
- Access details, such as a loft hatch or a shared roof
- Why you want a survey: buying, a leak, a storm or new work
- Where the property is, with the postcode

DIY checks: what’s safe
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.
It’s useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry, as it helps us focus the survey.

How the survey changes by roof type
Flat roof upstands and outlets
Upstands seal the edge of a flat roof where it meets a wall. If it’s too low, cracked or poorly dressed, water gets behind it.
Lead flashings
Water from a failed flashing can travel down the wall or along a rafter. That is why we check the flashings near a stain, not just the one directly above.
What we do, step by step
Before we start, tell us why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit typically takes about one to two hours, more where the leak is intermittent or the roof is large. Rural addresses near Sydenham can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we look at the stain and the ceiling around 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 every safe viewpoint.
- We email a written report showing where the water most likely gets in.
Before the survey
- Move anything stored under the loft hatch
- Unlock side gates and any roof access doors
- If you are buying, let the agent know when we are coming
Booking a survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just ring 07833 053749 or drop us an email when you are ready.

Questions from Sydenham
Is my home in Sydenham listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you cover Sydenham?
Yes, Sydenham is within the area we cover. We work right across London and the South East. You can phone 07833 053749 or send us an email with the address and some details.
Can you trace a leak in dry weather?
Typically, yes. Moisture detection shows where materials are damp even on a dry day. If a leak only appears in driving rain from one direction, we will tell you what we found and what’s most likely.
Will you fly a drone over my roof?
Yes, where it’s applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
What insurance do you have?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
Do I have to be there for the survey?
Someone needs to let us in if we are looking inside or in the loft. Access is agreed with you as you book.
Do you need to get into the loft?
Typically, if there is one and it can be reached safely. From inside, the underside of the roof frequently shows damp, staining or daylight that can’t be seen from outside.
