Roof leak investigations for homes and businesses in Hillstreet
On a flat roof, water can travel a long way under the covering. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath to narrow it down. Leaks under flat extension, garage and dormer roofs are common. Felt often lasts around 15 to 20 years, so age is part of the picture. Typical surveys look at damp patches next to the stack and ceiling stains that grow after rain, across valleys and parapet gutters, chimney stacks and slate and tile slopes.
Many homes in small places like Hillstreet face open ground, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A written record also helps if you need to explain it to anyone else.
We keep jargon out of it: where something needs attention, it says so plainly.

Wind, rain and roofs in Hillstreet
The coast is about 3 miles or less from Hillstreet, and places near the sea get more salt in the air and more wind than inland. Driving rain off the sea can be pushed into gaps that stay dry in calmer weather, and salt air slowly wears metal fixings. If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
Anyone responsible for a site like Calmore Junior School will know that tracing a leak on a big roof starts with where the water appears and works back. If you own a rental within reach of Totton station, a clear finding on where water gets in helps you brief a roofer straight away.
Hillstreet is about 2 miles north of Totton, in Hampshire. Houses, flats, blocks and commercial buildings in Hillstreet can all book roof leak investigations. Hillstreet is one of the towns and villages in Hampshire where we work. For surveys nearby, see our Southampton page.

How the survey changes by roof type
Lead flashings
A leak at a flashing often shows some way from the joint. That is why we check the flashings near a stain, not just the one directly above.
Slate and tile slopes
On slate roofs, corroded nails let slates slip. One slipped slate can be enough to cause a leak.
Useful tips for Hillstreet property owners
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Some tips:
- Put a bucket under the drip and move valuables
- Record whether it leaks in every downpour or only some
- Have an electrician check any wet fittings
- Check whether pipes or tanks run near the stain
If there are several possible sources, we list them in order of likelihood. Recommendations are prioritised by urgency where relevant, so you know what to deal with first.
Do not block the vents at the eaves. Good airflow reduces condensation, which is frequently mistaken for a leak. Check insulation does not block airflow at the eaves.
Questions from Hillstreet
Is the coastal weather around Hillstreet hard on roofs?
It can do. Within about 3 miles of the sea, as Hillstreet is, metal fixings wear faster and gales find any loose ridge or slate.
Do you cover smaller places like Hillstreet?
Yes, we do. Our area covers London and the South East, from towns to the smallest villages. Longer journeys are simply planned beforehand.
How long does a roof leak investigation take?
The visit typically takes about one to two hours, more where the leak is intermittent or the roof is large. We’ll confirm what to expect when we arrange the visit.
Does the report include photos?
Yes. The report includes photos of what we found.
What insurance do you have?
Our cover is professional indemnity plus public liability.
Is this an asbestos survey?
No. We don’t sample or test for asbestos. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
Why is the stain in a different place from the leak?
Water rarely drops straight down. It can follow a timber or the underlay a long way first, so the entry point is often well away from the mark. We follow the route back instead of guessing.
The survey, step by step
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photos as we go and record our findings for the written report. It normally takes between one and two hours, more where the leak is intermittent or the roof is large. Around Hillstreet, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. We only go where it’s safe.
- 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.
- We email a written report showing where the water most likely gets in.
Before we arrive
- Let us know about parking near the property
- Have any questions written down, so nothing gets missed
- Make sure we can get to the back of the property
Getting a price
Getting a price is simple: just phone 07833 053749 or email us, let us know about the property and we will explain which survey suits. The price is agreed up front.

What we’re asked to look at in Hillstreet
Slipped or missing slates and tiles let rain reach the underlay. Old bitumen felt may cope for a while, but it tears and sags with age, and very old roofs may have no underlay at all. On slate roofs, slipping is often caused by corroded nails.
A survey can pick up problems such as:
- Wet patches on loft insulation
- Condensation that looks like a leak
- Leaks below a flat extension roof
- Leaks at a dormer or roof window
For an older house near a landmark like St Anne's, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
Choosing a roof surveyor
- What they will not be able to tell you
- Which viewpoints they use to see the roof
- Their track record with similar roofs
- When you will get the report
DIY checks: what’s safe
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. Do not go up yourself.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That’s where a survey comes in, using safe viewpoints and a drone where it applies.
