About our flat roof survey in St Stephens
Our flat roof survey checks the waterproof covering and every detail around it, from edges and upstands to outlets and rooflights. We cover felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply roofs. It suits a small roof over an extension or garage as well as a large one over flats, offices or units. The findings go into a written report with photos, setting out the defects and what we’d recommend. If you’ve noticed signs of deflection in the roof deck and blistering in felt or asphalt, a survey will tell you what’s going on.
Flat roofs in smaller places like St Stephens can be more exposed, particularly where nothing shelters them, so wind catches loose edges and trims. Sun on a flat roof also ages felt and bitumen. The signs are splits, blisters and edges coming away, along with water that sits after rain. Standing water that lingers for days after rain is another sign worth watching for.
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.

What we can’t see
A survey is a proper look at the flat roof, but it cannot do everything. Its limits include:
- Parts of the roof that aren’t safe to walk on or view
- Asbestos testing, which needs a specialist asbestos surveyor
- A structural engineer’s assessment of the deck
If in doubt, call 07833 053749 or send us an email and we will recommend the right survey before booking. What a survey covers and doesn’t.

Practical tips
Over many surveys, some simple habits stand out:
- Watch the ceilings below the flat roof for stains
- Make sure new fixings through the roof are properly sealed
- Ask contractors to protect the roof if they work on it
- Book a survey every few years
Questions about the findings are always welcome. 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 usually lasts longer.
Checking the roof from the ground
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Flat and commercial roofs around St Stephens
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Within a mile and a half or so of St Stephens there are several hotels, and hotels, like offices and blocks of flats, frequently have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
For businesses in and around places like Village Arcade St Albans, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you look after a building such as Marlborough Science Academy, a large flat roof with a good many outlets and rooflights has many places where a membrane can fail. The streets around a church such as St. Stephen's Church are often among the oldest in a place, and if your house is among the older ones nearby, the joins between later flat roofs and the old walls are where problems usually start.
St Stephens is about 1 mile south-west of St Albans, in Hertfordshire.

For landlords and managing agents
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait.
If the property is let, the agent or a tenant can let us in, at a time agreed in advance. Surveys run on any day of the week, which helps when tenants work during the week.
St Stephens: your questions answered
Do you cover smaller places like St Stephens?
Yes, St Stephens is on our map. A small place gets exactly the same survey as a big one.
Do you cover commercial flat roofs around St Stephens?
Yes, commercial flat roofs are part of what we cover. Larger commercial roofs are quoted for the building.
Will you walk on the roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the loft space and a drone where applicable.
How do I arrange a flat roof survey in St Stephens?
Just ring 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day, weekday or weekend.
Will you fly a drone over my roof?
Where it is applicable and safe, yes. We are a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. It’s included in the Drone Roof Survey and, where it applies, the Premium Survey.
What’s in the survey report?
You get our findings in writing, part by part, with photos, finishing with recommendations. Points are put by urgency where it matters.
Can you survey in bad weather?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions aren’t right, we will talk to you about another date.
What we look for on each type of roof
Mastic asphalt
Mastic asphalt is a heavy, seamless covering often found on older blocks, balconies and commercial roofs. The survey checks for crazing, cracking, blistering and splits where the asphalt turns up the walls.
Rooflights and upstands
Rooflights, lanterns and upstands are where many flat roof leaks begin. We check the seals and the covering around each one.
How it works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect between one and two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. For a survey in St Stephens, we agree the time, the access and parking before the day. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- First we go through the roof, what’s beneath it and any problems so far.
- The roof is viewed from safe positions, including the roof itself where that is safe.
- We check the covering for splits, blisters, ponding and wear.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photos and recommendations, comes to you by email.
Getting ready for the survey
- Make a note of anything you’d like us to look at
