Flat roof survey in Sewardstone: what you get
Buying a home with a flat-roofed extension, dormer or garage? It helps to know that roof’s condition before you exchange. Many felt roofs need renewing after around 15 to 20 years, and EPDM and GRP frequently go on for longer. Our report records the covering, how it’s holding up and any defects we can see, with photographs of each. You then have something specific to put to the seller or agent. If you’ve noticed edge trims that have lifted or split and blocked or damaged outlets, a survey will tell you what’s going on, whatever the roof.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Sewardstone, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
If any part of the flat roof couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Why it is worth a survey now in Sewardstone
Most flat roofs are out of sight, so they’re easy to forget. Owners frequently learn the roof is at the end of its life only when it leaks. Regular surveys mean it won’t come as a surprise. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.

- Single-ply membranes
- Felt flat roofs
- EPDM rubber
- Mastic asphalt
Signs you need a flat roof survey in Sewardstone
Every flat roof covering has a working life. Felt roofs often last around 15 to 20 years, EPDM often 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. We can tell you how your roof is doing, whatever its age.
People normally book a survey when they’ve noticed something like this:
- Splits and cracks in the covering
- Outlets that hold water back
- Signs of deflection in the roof deck
- Gaps at upstands and abutments
For site and facilities teams at buildings such as Prince of Wales Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Before booking any roof surveyor
- When you will get the report
- What they will not be able to tell you
- Their track record with similar roofs
- What the report includes, and whether it has photographs
Different roofs, different checks
Felt and built-up roofs
Built-up felt is one of the most common flat roof coverings on extensions, garages and dormers. The survey checks for blisters, cracks, open laps and bare patches where the surfacing has worn.
Single-ply membranes
Single-ply relies on its welded laps staying sound. We look at seams, corners and the joints around outlets and upstands.
How it works
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. The survey itself takes an hour or two on an ordinary house, rising to roughly 3–4 hours on a commercial building. In Sewardstone, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First we go through the roof, what’s beneath it and any problems so far.
- We check the roof from the ground, windows and the roof where it’s safe.
- The covering is checked for wear, splits, blisters and standing water.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- A written report with photos and recommendations is emailed to you.
How to prepare
- Make sure the loft hatch can be reached
- Make a note of anything you’d like us to look at
- Check pets are kept safely away

Advice
Common questions in Sewardstone
How do I find out if my home in Sewardstone is listed?
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.
Do you cover Sewardstone?
We do. The survey and report are the same in Sewardstone as anywhere else, and visits run on weekdays and weekends.
Can you test old roof sheets for asbestos?
We do not carry out asbestos surveys. Buildings built or refurbished before 2000 may contain asbestos, for instance in cement roof sheets. We note anything that could contain it, and a specialist asbestos surveyor should check it before it is disturbed.
How soon will I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, like an exchange date, let us know as you book.
How many years has my flat roof got left?
There’s no honest way to give an exact number of years. As a guide, felt often lasts around 15 to 20 years, EPDM frequently 30 to 50 and GRP up to about 30, but your report describes the actual condition.
What’s the best way to book?
Simply ring 07833 053749 or use the contact form with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
Do you look for flat roof leaks?
We check the covering and every detail where leaks commonly start, recording anything that could let water through. Where the source isn’t obvious, a roof leak investigation or electronic leak detection may be the next step.
Local flat roofs in Sewardstone
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses like Forty Hall, about 2.8 miles west, show how far back building in the area around Sewardstone goes. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
For a London address like Sewardstone, it helps to know about controlled parking before the day. If you own a rental within reach of Enfield Lock station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
