Roof leak investigations for homes and businesses in Haslar
Some leaks only appear in certain weather. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Telling us when it happens helps a lot and so do photos. We look for the clues it leaves behind, like tide marks, stained timbers and damp underlay. Moisture readings show where materials are still wet. If you are worried about water that shows only in certain storms and water dripping from rafters or underlay, a survey will tell you what’s going on, on valleys and parapet gutters, rooflights and dormers and slate and tile slopes alike.
For a small place like Haslar, the inspection is the same as anywhere: we simply plan the journey and access ahead. It helps to know where the water appears, in what weather, and what you’ve seen outside, plus any earlier repairs. If you have photographs of the water coming in, they help as well.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

What you can safely check yourself
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. Don’t go up yourself.
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Roof leak investigations in Haslar: local notes
Haslar lies within about 1 mile of the sea, and places near the sea get more salt in the air and more wind than inland. In a coastal gale, rain is driven sideways into laps, verges and flashings. A number of Hampshire villages keep thatched roofs on their older buildings. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Each of these roof types has its own typical places for water to get in.
If you live in an older home near St Francis, leaks on older roofs frequently start at lead flashings, valleys or around old chimney stacks. Shop and office owners around Tricorn Centre may find that water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.

What affects the cost of roof leak investigations
When we price a survey, we consider:
- Features like valleys, chimneys, dormers and parapets
- The use of thermal imaging or a drone
- Roof area
- Commercial roofs and larger buildings
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. Prices start from £150, including VAT.
What to tell us when you get in touch
These details help when you get in touch:
- What’s prompted the survey
- Where any leaks, stains or damp patches show inside
- Any photos you have, taken from the ground or a window
- When you need the report by
When you’re ready to go ahead, phone 07833 053749 or drop us an email. We’ll suggest a package, agree the price and find a date, weekday or weekend.
What happens on the day
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. In total, it takes an hour or two at most homes, or half a day or so for a commercial building. Rural addresses near Haslar can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.
- You tell us where the water shows and when it appears.
- Inside, we check the damp area and the roof space above it.
- Likely entry points outside are looked at, from flashings and valleys to gutters and outlets.
- Where it helps, we take moisture readings and use thermal imaging.
- You receive a written report with photos showing the likely source and what needs attention.
Preparing for the visit
- If it is not your property yet, arrange access through the agent
- If the roof is shared, arrange access with whoever manages the building
- Make a note of anything you’d like us to look at
Booking a survey
Most bookings start with a short call: call 07833 053749 or send us an email, and we will ask about the building and what you need. You’ll have a price before anything is arranged.

For landlords and managing agents
Letting agents frequently book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant in advance.
If the property is let, the agent or a tenant can let us in. Surveys run on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
What we are asked to look at in Haslar
When a slate slips or a tile cracks, the underlay takes the water. 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.
Most people get in touch after spotting one of these:
- Damp ceilings under a flat roof
- Water coming in around a roof light or dormer
- Wet patches on loft insulation
- Damp on a chimney breast
Landlords with a home close to Portsmouth Harbour station may find that a tenant living with a leak needs the cause found, not just the stain painted over.

Haslar questions
Will you come out to Haslar?
Yes, smaller places are covered as well as towns. We survey roofs across London and the South East. Let us know about access, parking and anything unusual about getting there as you book.
Do roofs near the sea, like those around Haslar, take more of a battering?
Generally, yes: wind and salt air take more of a toll near the sea. Ridges, verges, flashings and fixings are where it usually shows, and Haslar is within about 1 mile of the coast.
Will you check the loft?
If it’s needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement, as far as the space allows.
How do I book a survey in Haslar?
Just ring 07833 053749 or email us with the address. We’ll ask a few questions, confirm the price and agree a date, weekday or weekend.
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, and it’s agreed before booking.
Will you fly a drone over my roof?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
Can you give me structural calculations?
No. Visible signs such as deflection or sagging are recorded, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
How the survey changes by roof type
Flat roof upstands and outlets
On a flat roof, a leak can show some distance from the split. Where conditions allow, moisture readings and thermal imaging help narrow it down.
Lead flashings
A leak at a flashing often shows some way from the joint. We check every flashing that could feed the stain.
