Flat roof surveys for homes and businesses in Tewin
A flat roof doesn’t shed water the way a pitched roof does. Water lies on the surface for longer, so a small split or a blocked outlet can soon lead to a leak. The surface, the falls, the upstands and the trims are all looked at closely, and we note any sign that the deck below has got wet. The aim is to find problems before they show up as a stain on a ceiling. If you’re worried about splits and cracks in the covering and pools of water lying on the roof, we can find out what’s behind it.
Somewhere as small as Tewin, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. We simply plan the journey and access ahead of time. If there are outbuildings or garages with flat roofs, mention them when you book.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

What a flat roof survey looks like in Tewin
About 2.1 miles west lies Digswell House, a reminder of how long the area around Tewin has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Anyone responsible for a site like Ridgeway Academy will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you look after a shop, office or commercial unit, for instance near Howard Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling.
Tewin is about 2 miles north-east of Welwyn Garden City, in Hertfordshire.

What happens if roof problems are left?
A survey can show whether a whole new roof is needed or whether the problems are in a few places. Sometimes a few details are to blame, and sometimes the covering has simply had its day. Our report gives you the evidence to discuss with a roofer. For older village homes like those around Tewin, the right replacement materials aren’t always easy to find quickly. Spotting a problem early leaves room to find them.

Tewin questions
How do I find out if my home in Tewin is listed?
We cannot 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 Tewin in the area you cover?
We do. The survey and report are the same in Tewin as anywhere else.
Do you go up onto the roof?
It depends on what’s safe: on the roof where it’s safe, and from windows, nearby vantage points and inside. Fragile rooflights and fragile sheets are never walked on.
How long will you be at the property?
That depends on the size and shape of the roof; most visits take about one to two hours at a typical home, with bigger or more complicated roofs taking longer. The report is sent afterwards by email.
Can you survey in bad weather?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions are not right, we’ll talk to you about another date.
What’s in the report?
It sets out what we found, why it matters and what we recommend, with photos throughout. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Do you look in the loft space?
If it is needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Checking the roof from the ground
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us as you book, as it helps us focus the survey.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.

Tips from our surveys
There is plenty you can do without going near the roof. What helps most:
- File the paperwork for the roof and any repairs
- Note any new marks on ceilings beneath the roof
- Keep people off the roof unless they need to be there
- Check the outlets after the leaves fall
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, so you can talk the findings through.
Small defects are simpler to deal with while they’re still small. A flat roof that is looked after between surveys usually lasts longer.
How the survey works
After the inspection, everything we found is written up as a written report with photos, emailed to you. As for time on site, it typically takes between one and two hours for a small flat roof at home, and longer for a large commercial one. For a village or hamlet like Tewin, the journey is planned ahead of time: let us know about lanes, gates and parking. On the day, we inspect what can be seen safely, inside and out.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- We view the roof from the ground, from windows and from the roof where it is safe to do so.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- Where there’s safe access, we check the ceilings and spaces below for signs of water.
- The findings are written up with photographs and recommendations and emailed to you.
Before we arrive
- Let us know about any leaks, stains or damp patches you know of
- Keep pets in another room
- If the roof is shared, arrange access with whoever manages the building
Booking a survey
Booking is simple: just call 07833 053749 or email us, let us know about the property and we will explain which survey suits. We confirm the price before anything is booked.
Advice
Surveys for landlords and agents in Tewin
An agent can book and manage the survey for a landlord, and the report can go to both. Access is agreed with the tenant beforehand.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work.
When to book a survey in Tewin
Ponding keeps the covering wet and wears it faster. It usually comes from poor falls, a blocked outlet or a deck that has dipped. Leaves and silt from nearby trees can soon choke an outlet.
Things that often lead to a survey include:
- Ponding water that doesn’t drain away
- Dips that suggest the deck is deflecting
- Upstands pulling away from walls
- Raised blisters across the surface
If you let a flat or house near Welwyn North station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Before booking anyone
- Are they insured for the work?
- Whether the loft is part of the inspection
- What the survey will not cover
- How much experience they have with roofs like yours
