Flat roof survey in Langley Bottom: 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 often go on for longer. Our report records the covering, how it’s holding up and any defects we can see, with a photo of every defect. You then have something specific to put to the seller or agent. Common reasons to book are blistering in felt or asphalt and blocked or damaged outlets, on EPDM rubber, GRP fibreglass and upstands and outlets.

Somewhere as small as Langley Bottom, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when you book.

Every survey ends with a written report, with photographs, sent by email. It sets out the condition of the flat roof, any defects and our written recommendations.

Landlords, agents and block managers in Langley Bottom

Where a roof is shared: we need access agreed with the building owner or managing agent. Let us know about it when you book and we will plan the survey around it.

We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Bigger roofs take more time, and they’re priced for the size.

Common roof problems in Langley Bottom

Flat roofs swing between hot and cold more than most parts of a building. That movement pulls at seams, laps and the joints between boards, and in time it can open up splits and cracks. Coverings that have hardened with age tend to suffer most.

We are often asked to look at:

  • Blisters and bubbles in the covering
  • A sagging deck under the covering
  • Outlets that hold water back
  • Gaps at upstands and abutments

For landlords with property near Stevenage station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Before booking anyone

  • What’s outside the scope of the survey
  • Do they have a CAA Flyer ID and Operator ID for drone work?
  • Whether VAT is added on top

What a roof survey includes

Leave it or get it looked at?

By the time a flat roof leak shows indoors, water has already passed through the roof build-up. We can pick up worn covering and failing details sooner, while there is still time to plan the work. Matching old materials, such as handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.

The Premium Survey includes thermal imaging and drone inspection where it applies, from £400 with VAT included. We’ll tell you which package suits the questions you have.

Langley Bottom: your questions answered

Is my home in Langley Bottom listed or in a conservation area?

We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.

Is Langley Bottom within the area you cover?

Yes, Langley Bottom is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.

Will I get photos?

Yes, every report has them. Pictures sit next to the findings they show, which makes the report easy to follow.

Are you insured?

We hold professional indemnity and public liability insurance.

Can you survey a flat roof on an office or unit?

Yes. Commercial and residential flat roofs are both covered. A commercial roof typically takes about 3 to 4 hours on site, longer if it’s large or complex, with larger roofs quoted on their size.

How many surveys have you done?

Over 5,000 surveys so far, across 20+ years of surveying roofs, and 98% of clients are satisfied.

How quickly is the report sent?

That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.

Flat and commercial roofs around Langley Bottom

Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. With Knebworth House about 1.8 miles south-east, Langley Bottom sits in an area with a long building history. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.

For site and facilities teams at buildings like The Thomas Alleyne School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Roof by roof

Single-ply membranes

Plant, fixings and foot traffic can all damage a single-ply roof. We note any punctures, tears and loose areas we can see.

Felt and built-up roofs

On felt, the upstands and edge details often fail before the main surface. Every upstand and edge is looked at, with photos of any that have lifted or cracked.

The survey, step by step

Safety comes first on every visit. We inspect whatever is safely visible, and if part of the roof can’t be seen, the report says so. Most visits take about 1–2 hours for most houses, and more on a big or complicated roof. Older roofs in small places like Langley Bottom can have low, tight loft spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.

  1. You send us the address and, for commercial roofs, an idea of the roof’s size.
  2. Inside, we look for signs of water under the roof where we can reach.
  3. The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
  4. Each defect is photographed and its likely cause noted.
  5. The report explains the condition and recommends what to do first.

Getting ready for the survey

  • Make a note of anything you’d like us to look at
  • Point out any leaks or damp patches
  • If the roof is shared, arrange access with whoever manages the building

Getting a price

Every survey is priced before it’s booked, so you know where you stand. Our price is from £150, including VAT. For a price for your roof, phone 07833 053749 or drop us an email.

Prices quoted always include VAT, and the written report is part of the package. Prices start from £150, including VAT. Size, height and access decide where your roof falls.

What to tell us when you contact us
