Hemel Hempstead questions
Does a conservation area affect roof work in Hemel Hempstead?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Should a flat-roofed garage or porch in Hemel Hempstead be checked too?
Often, yes, so mention it when booking. Flat-roofed garages and porches are common in new towns like Hemel Hempstead, and older felt coverings may be near the end of their life.
Does this replace a RICS home survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you’ll need a RICS survey as well.
How do I arrange a roof leak investigation in Hemel Hempstead?
To book, ring 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We’ll confirm the price and find a day that suits.
Will you go up on the roof?
Only when it’s safe. Some roofs are too steep or fragile to walk on safely. Safe viewpoints, the loft and a drone where it applies let us see the rest.
How much is a survey?
Roof leak investigation starts from £150, including VAT. What you pay for your roof depends on its size, height, access and the package.
Do you use thermal imaging to find leaks?
We use thermal imaging where it helps, and it is part of the Premium Survey. It picks up temperature patterns rather than water, so we confirm its findings with moisture readings.
Roof leak investigation in Hemel Hempstead
The aim is to find where the water is getting in and explain it. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. It gives any roofer a clear brief. We find and report the source, and the repair itself is a separate job. We survey chimney stacks, valleys and parapet gutters and the roof space, and common reasons people get in touch are damp walls below an overflowing gutter and damp on a chimney breast.
When a storm passes over a place the size of Hemel Hempstead, lots of roofs can be hit at once. An independent record of what can be seen, with photos, helps you explain the damage or the leak to whoever deals with it next. What a report cannot do is decide an insurance claim: that is up to the insurer. Wear and tear is normally excluded, so it helps to know what is old and what is new.
Where we can’t see part of the leaking roof, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

The survey, step by step
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. The survey itself takes an hour or two for most homes, though a hard-to-trace leak can take longer. Jobs in Hemel Hempstead might be a terraced house one day and a block of flats the next. Let us know the type of building and who can let us in, so the right access is in place on the day.
- You let us know where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- From the roof space, we trace the water’s route where there is safe access.
- We inspect the likely entry points outside, from ground level, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Preparing for the visit
- Unlock side gates and any roof access doors
- Tell us about any leaks, stains or damp patches you know of
- Have any questions written down, so nothing gets missed

Advice
Hemel Hempstead roofs and the weather
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. The covering and its details give the first clues when tracing where water is coming from. Hemel Hempstead was built as one of England’s post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Low pitches let wind-driven rain reach further under the tiles, and flat-roofed garages and porches are common leak points.
Historic houses such as High Elms Manor, about 4.6 miles south-east, show how far back building around Hemel Hempstead goes. Older roofs in the area may have lead flashings, valleys and gutters that have been patched many times. If you own a rental within reach of Apsley station, tracing a leak quickly matters when a tenant is living with it.

Checking the roof from the ground
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we check the roof.
What we look for on each type of roof
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. We check each one as far as we can safely see.
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Older felt may hold for a while, but it tears with age.
Useful tips for Hemel Hempstead property owners
You do not need to be a roofer to help. What helps most:
- Note the weather when the leak shows
- Let us know about any past repairs to the roof
- Do not touch fittings that water is reaching
- Photograph the stain each time it appears
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention.
Keep the loft space ventilated. Good airflow reduces condensation, which is often mistaken for a leak. Check insulation doesn’t block airflow at the eaves.
When you need someone else
In fairness, there are limits to any roof survey:
- Leaks from plumbing, tanks or pipework rather than the roof
- A promise to find every leak on a single visit
- Carrying out the fix

Do you need a roof leak investigation in Hemel Hempstead?
Many leaks begin at a flashing. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. Once that seal cracks or lifts, water gets behind it, often well away from where it shows.
Here are some of the things we see frequently:
- Brown rings on upstairs ceilings
- Water coming in around a roof light or dormer
- Drips from nail tips in a cold loft
- Water through the ceiling under a flat roof
If you look after a building like Broadfield Academy, a leak through a large roof is frequently found some distance from where the water shows inside.
Before you book anyone
- How long they’ve been surveying roofs
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Will they check the loft as well as the outside?
- How long the report takes to arrive
