Flat roofs in High Wych
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. With Much Hadham Palace about 3.9 miles north-west, High Wych sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
If your home is one of the older ones in the streets near Parish Church of St James the Great, the flat roofs on later extensions tend to wear out long before the main roof. If you let a flat or house near Harlow Mill station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
High Wych is about 3 miles north of Harlow, in Hertfordshire. If you are in High Wych, booking works exactly as it does anywhere else: get in touch, agree the price and pick a day.

How a flat roof survey works in High Wych
A flat roof survey looks at the covering, the edges, the outlets and the details where the roof meets walls and rooflights. Felt, asphalt, EPDM, GRP and single-ply PVC or TPO roofs are all part of the work. It suits a small roof over an extension or garage as well as a large one over flats, offices or units. You get a written report with photos and our recommendations. Common reasons to book are ponding water that doesn’t drain away and outlets that hold water back, across GRP fibreglass, upstands and outlets and felt flat roofs.
Older buildings in small places like High Wych may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Tips that help
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Ask whoever fits equipment on the roof to make good the covering
- Book a survey every few years
- Treat rooflights and old sheeting as fragile
- Limit foot traffic on the covering
If anything in the report is not clear, just ask us. Standard Surveys come with a follow-up consultation, and Premium Surveys with an in-person one, giving you a chance to go through what we found.
Get splits, lifted seams and loose trims seen to while they’re small. A flat roof that is looked after between surveys normally lasts longer.
Why it’s worth a survey now in High Wych
Ponding seldom gets better on its own. It typically points to an outlet, the falls or a sagging deck, and each wet season wears the covering further. Knowing the cause early gives you more choice over what to do. In a place like High Wych, a barn or garage roof left to fail puts whatever is inside at risk. It is worth including them in a survey before a winter does the damage.

When to book a survey in High Wych
Many flat roof problems start at the details rather than the main surface. Upstands, trims, outlets and rooflight kerbs each move and weather in their own way. Where they weren’t finished well, they tend to fail before anything else.
A survey can pick up problems such as:
- Damaged trims at the roof edge
- Gaps at upstands and abutments
- Blistering in felt or asphalt
- Dips that suggest the deck is deflecting
For site and facilities teams at buildings like High Wych Church of England Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Before you book any roof surveyor
- Do they have a CAA Flyer ID and Operator ID for drone work?
- How long they’ve been surveying roofs
- Whether they hold professional indemnity and public liability insurance
- Whether the price includes VAT
FAQs for High Wych
Do you cover High Wych?
We do. The survey and report are the same in High Wych as anywhere else, and visits run on weekdays and weekends.
Do you cover smaller places like High Wych?
Yes, we do. We survey roofs across London and the South East, and smaller places are part of that. Longer journeys are simply planned ahead of time.
How long have you been surveying roofs?
We’ve completed more than 5,000 surveys, over more than 20 years, and 98% of clients are satisfied.
How long does the survey take?
It normally takes about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. You’ll then get the report by email.
Do you give a life expectancy for the roof?
We don’t put a figure on it. As a guide, felt often lasts around 15 to 20 years, EPDM often 30 to 50 and GRP up to about 30, but your report describes the actual condition.
How quickly is the report sent?
It depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
Which days do you carry out surveys?
We carry out surveys seven days a week. To find a day that suits you, phone 07833 053749 or send us an email.
What a survey costs
Every roof is different, so prices are confirmed before booking. This is what makes a difference:
- How many separate roofs there are, such as extensions, dormers and garages
- Whether you choose the Basic, Standard or Premium Survey
- Whether it’s a home or a commercial building
- Building height and the viewpoints available
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Prices start from £150, including VAT.
Helping us price your survey
Here’s what helps us most when you contact us:
- Any stains, drips or damp patches you’ve seen indoors
- The style of property, from a terrace to a block
- Dates you are working to, such as exchange
- Any photos you have, taken from ground level or a window
Photos help, if you have them. Pictures from the ground or a window are fine; never climb up to get a better view. To get started, ring 07833 053749 or send us an email.
How it works
We look at the roof from outside and, where it is relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey usually takes about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Older roofs in small places like High Wych can have low, tight loft spaces, so it’s useful to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- We view the roof from safe positions and never walk on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Getting ready for the survey
- If you’re buying, let the agent know when we are coming
- Make sure we can get to the back of the property
- Agree roof access with the managing agent if it’s shared

Felt and built-up roofs
On felt, the upstands and edge details often fail before the main surface. We check each one and photograph any that have split or pulled away.
Mastic asphalt
Older asphalt can become brittle and crack as the roof moves. The report shows where it’s cracking and how far it seems to extend.
