An experienced roof surveyor for roof surveys in Northaw Valley. Over 5,000 surveys and 20+ years behind us.
- Slates or tiles that have slipped or broken
- Crumbling chimney pointing or cracked flaunching
- Cracked or blistered flat roof coverings
What happens on the day
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, take photos as we go and make notes for the report. Most visits take an hour or two for an ordinary house roof, and longer if there are extensions, dormers or several chimneys. Cottages and farmhouses around Northaw Valley often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- We start with the property details and any concerns.
- A visit is booked for a weekday, Saturday or Sunday.
- Outside, we inspect from ground level, windows and other safe vantage points, and from the roof where safe.
- Inside, we check the loft space where there is safe access.
- We email a written report with photos and recommendations.
Getting ready for the survey
- Show us where any leaks or stains appear
- Have any questions written down, so nothing gets missed
- Have any paperwork from past roof work to hand
Getting a price
Roof survey starts from £150, including VAT. The exact figure depends on the roof and the package, and you can ring 07833 053749 or drop us an email to find out.

Roof surveys for homes and businesses in Northaw Valley
Three packages cover most roofs: Basic from £150, Standard from £250 and Premium from £400, with VAT included. Basic is a visual inspection with photos and written recommendations. Standard and Premium go further, such as moisture detection, a structural check, thermal imaging and a drone where applicable. Each one comes with a written report. If you’re worried about flashings that have come away from the wall and loose ridge or hip tiles, we can find out what’s behind it, on ridges, hips and valleys, chimney stacks and the roof space alike.
Somewhere as small as Northaw Valley, homes are frequently older cottages and farmhouses, with outbuildings and some newer houses. Older roofs may be clay tile, slate, stone or thatch, frequently with chimneys that have stood a long time. We report on everything that’s safely in view, and thatch is a specialist material. Chimneys and lead flashings on old roofs frequently need the most attention.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

Businesses and commercial landlords can book us too, from shops and offices to industrial units. Larger roofs take longer, so they’re priced to suit.
Common roof problems in Northaw Valley
Every roof takes years of rain, wind, sun and frost. Strong gusts work at anything that isn’t firmly fixed, while rain gets into every gap. What starts as one slipped slate can become a leak.
Here are some of the things we see often:
- Blocked, sagging or leaking gutters
- Cracked mortar along the ridge
- Crumbling chimney pointing or cracked flaunching
- Lifted, split or missing lead flashings
Landlords with a home close to Crews Hill station may find that the gap between tenancies is a good time to have the roof looked at.
Questions to ask before booking
- Whether they hold professional indemnity and public liability insurance
- Whether you can ask questions once you have the report
- How long the report takes to arrive
- Whether VAT is added on top
Should I look at the roof myself first?
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
Honest limits
Every survey has limits, and we’d rather be clear about that before you book. Keep these in mind:
- Confirmation of asbestos in soffits or cement sheets
- Faults hidden behind ceilings or boarding
- Structural calculations (that is a structural engineer’s job)
If in doubt, ring 07833 053749 or email us and we will suggest the right survey. The full list of what we check.

Your questions about roof surveys in Northaw Valley
Do you cover smaller places like Northaw Valley?
Yes, Northaw Valley is on our map. A small place gets exactly the same survey as a big one.
I let a flat near Crews Hill station. Can you check the roof?
Yes, landlords and agents are among the people we work for. You can phone 07833 053749 or use the contact form with the address and what you need, and we’ll talk through which survey suits.
Do I have to be there for the survey?
Not necessarily. If we only need the outside, we can agree that beforehand, but anything inside needs someone there to give access.
Will the report say how many years my roof has left?
Not as a figure. The report explains the condition of each part and the signs of wear, with recommendations ranked by urgency.
Do you look in the loft space?
If the survey needs it and the loft space can be reached safely, yes. A clear path to the hatch helps, and if the loft can’t be reached safely, the report says so.
How quickly will I get the report?
It depends on the package: Basic within 48 hours, Standard within 24 to 48 hours and Premium the same day. We send it by email.
How much is a survey?
Prices start from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, with VAT included.

Useful tips for Northaw Valley property owners
You don’t need to be a roofer to help. Here’s what helps most:
- Make sure we can open the loft hatch
- Mention any flat roofs as well as the main roof
- Mention any damp patches when you book
- Keep the report with your property records
We email the report to you. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium. Findings are explained in plain words.
Every so often, look in the roof space with a torch, keeping to boarded areas. Look for water marks, damp wood and chinks of light. Take photos of anything that changes.

Wyllyotts Manor, about 2.4 miles west, is one of the historic houses in the wider area around Northaw Valley. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
