About roof leak investigations in Hertfordshire

Moisture readings and thermal imaging are used where they’re useful. Moisture readings show which materials are wet. A thermal camera shows patterns of temperature rather than water, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. The best thermal results come after a sunny day, with a dry roof and little wind. We’re often asked to look into leaks that appear only in driving rain and staining where a gutter or parapet meets the wall, on rooflights and dormers, valleys and parapet gutters and chimney stacks.

Once we have finished looking, we write up our findings as a written report with photographs. On timing, most surveys take an hour or two for most houses, and longer for a large or complex roof.

We help you choose the package that suits the leak.
We agree a date, including weekends.
We inspect inside and out, starting from the stain.
Where it is useful and included, we take moisture readings and use thermal imaging.
You get photos, the likely cause and clear recommendations.

How our prices work

A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. We’ll give you the figure before anything is booked.

What’s near Watford

Around Watford, our work takes us to homes and buildings near The Estcourt Arms, Watford St John's Church of England Primary School and Church of St Andrew and the streets around them. You’ll also find Cassiobury Park (0.8 miles west) and The Watford UTC (0.5 miles east). There is a railway station in Watford itself: Watford Junction station. Other landmarks nearby include Hilfield Castle (2.8 miles east) and Charter Place (0.5 miles south). For a walk, there is Harrow Weald Common.

Roof leak investigations across Hertfordshire: local notes

Across Hertfordshire, we check leaks and storm damage on homes and businesses, from Watford, Hemel Hempstead and Stevenage to the quieter places in between. Each report records what was seen, with photos.

Our area takes in slate-roofed London terraces, clay-tiled Weald houses, Essex weatherboarding and post-war new towns. Roofs in Hertfordshire are part of that picture.

Watford: If you live in an older home near Church of St Andrew, water on an older roof tends to find its way in at the lead, the valleys or the chimney. Shop and office owners around Charter Place may find that a leak can close part of a shop or office, so finding the cause quickly matters.

Common roof problems in Hertfordshire

Valleys carry a lot of water. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. The stain may appear well away from the valley itself.

We are often asked to look at:

Drips in the loft during heavy rain
Brown rings on upstairs ceilings
Wet patches high on an inside wall
Water that shows only in certain storms

Landlords, agents and block managers in Hertfordshire

Businesses and commercial landlords can book us too, including offices, shops and units. Bigger roofs take more time, so they’re priced to suit.

Landlords and agents in Hertfordshire book surveys as well as householders. A written report with photos gives you a clear record of the leaking roof, which helps you plan work between tenancies.

Checking the roof from the ground

The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That’s where a survey comes in.

After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.

What a survey doesn’t cover

Before booking, it is worth knowing what a survey won’t do:

Structural calculations (that’s a structural engineer’s job)
Water from pipes, tanks or heating systems
Putting the leak right

Roof by roof

Parapet and box gutters

A butterfly roof drains to a central valley gutter. Problems there often show in the rooms on the top floor.

Slate and tile slopes

Cracked mortar lets ridge and hip tiles move. Rain can then run in at the ridge.

Common questions in Hertfordshire

Do you carry out surveys on Saturdays and Sundays?

Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.

Is this a RICS survey?

No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.

Is Hertfordshire in your area?

Yes. Our area covers London and South East England, Hertfordshire included.

Why is not the leak directly above the stain?

Rain that gets in will run along whatever it lands on. On a pitched roof it often runs down a rafter before it finds a way through the ceiling. Following that route is what our investigation does.

Can you tell me if my roof has asbestos?

No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.

Does the report include photographs?

Yes, every report has them. Pictures sit next to the findings they show, so you can see what we mean.

How experienced are you?

We have more than 20 years’ experience and have carried out more than 5,000 surveys.
