Why it is worth a survey now in Letchworth Garden City
Damp loft insulation loses much of its value. A slow leak can soak it for months before a stain appears. The sooner the cause is found, the less needs replacing. A defect spotted early can be planned and budgeted for, while one found after water comes through normally has to be dealt with in a hurry, in Letchworth Garden City as anywhere.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.

Roof leak investigation in Letchworth Garden City: what you get
Our job is to find the likely source and tell you. You get a written report with photos showing the likely entry point and the route the water is taking, and recommends what should be done. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, and the repair itself is a separate job. Typical surveys look at ceiling stains that grow after rain and wet patches on loft insulation, on chimney stacks, flat roof details and lead flashings.
When a storm passes over a town like Letchworth Garden City, loose tiles, slates and ridges are the first to move. Many policies treat gusts of about 55 mph as storm conditions, though it varies. A report setting out the damage, with photographs, helps you explain what you’ve found, whether to an insurer or a roofer. Policies usually exclude wear and tear, which is why the age of the damage matters.
The report records the leaking roof as we found it on the day. It is useful straight away, and a good reference for later, for example when you want to check whether anything has changed.

Tips from our surveys
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Note the weather when the leak shows
- Mention any plumbing above the damp area
- Stay off ladders and the roof
- Check the loft is accessible
If condensation is the cause, we explain it, with recommendations on ventilation. That avoids roof work that wouldn’t help.
Keep the loft space ventilated. Good airflow reduces condensation, and condensation is a common false alarm. Keep insulation clear of the eaves.
What we are asked to look at in Letchworth Garden City
Many leaks begin at a flashing. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in, frequently well away from where it shows.
A survey makes sense if you’ve noticed:
- Ceiling stains that grow after rain
- Damp walls below an overflowing gutter
- Leaks that appear only in driving rain
- Water coming in around a roof light or dormer
Anyone responsible for a site like Pixmore Junior School will know that water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
What to check before booking
- Whether VAT is added on top
- What follow-up you get after the report
- Which viewpoints they use to see the roof
- Whether the inside of the roof is included
What we can’t see
Before you book, it is worth knowing what a survey won’t do:
- What’s under the covering or behind the plaster
- Leaks from plumbing, tanks or pipework rather than the roof
- An intermittent leak that shows no trace on the day
If you are not sure which survey you need, phone 07833 053749 or use the contact form and we will give you a straight answer. What a survey covers and does not.
What this survey covers
- Slate and tile slopes
- The roof space
- Rooflights and dormers
- Lead flashings
- Flat roof details
- Chimney stacks
- Valleys and parapet gutters
The survey, step by step
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from each safe vantage point, take photographs as we go and record our findings for the written report. Most visits take between one and two hours, more where the leak is intermittent or the roof is large. Most visits in a town like Letchworth Garden City start at the front of the house and work round to the back. The back garden is frequently where extensions, dormers and rear slopes are best seen, so unlocked gates help. Then, if it can be reached safely, we look in the loft.
- You get in touch with details of the leak and any photos.
- Inside, we check the damp area and the roof space above it.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- Where it helps, we take moisture readings and use thermal imaging.
- We email a report with photos, the likely entry point and recommendations.
Before we arrive
- Gather any invoices or paperwork from past roof work
- Mention any parking restrictions on your street
- Keep pets inside or away from the areas we’re looking at
