When is a flat roof survey worth it in Calne?
Older extensions and garages in Calne frequently have felt roofs that have been patched several times. Before paying for another repair, many owners want to know whether the roof has much life left. That is exactly the question a condition survey answers.
Calne's flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches, with plenty on shops with flat-roofed rear stores below flats too. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage.
How much does a flat roof survey cost in Calne?
At South West guide rates, a condition survey and leak investigation comes to £150–£310 including VAT. We confirm the price once we've traced the leak or seen the damage.

How long does a flat roof survey take and how long is it valid?
A survey of a typical garage or extension roof usually takes an hour or two on site. Larger, higher or multi-area roofs take longer, and the written report follows afterwards.
A survey describes the roof on the day it was inspected. It stays a useful baseline for planning, but roofs change, particularly older ones and after a hard winter or a storm. If you are using a report to plan a replacement some time later, or after a fresh leak, a short follow-up check is sensible. For roofs you manage over the long term, a regular inspection backed by the maintenance checklist picks up problems early.
What's included?
- Plain written report with ranked recommendations
- Moisture meter readings across the roof
- Free quote if replacement is the right answer
- Checks on walls, copings and trays above the roof
Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

Can a survey tell me if my flat roof has condensation rather than a leak?
It can often point to it. Damp that appears in cold weather without rain, a cold roof build-up with little ventilation and a dry covering above the damp all suggest condensation rather than a leak.
Can you trace a flat roof leak without opening the roof up?
Often, yes. Careful inspection and moisture readings can usually locate the problem area. Where they can't, a small core sample is the most reliable way to confirm what is happening under the covering.
