Get a quote →The By Brook valley creates high humidity and heavy tree canopy — moss growth rates are among the fastest in our Wiltshire coverage, and lead corrosion is accelerated by valley moisture. For flat roofing work in Box, this means specification choices that reflect the actual conditions rather than generic Wiltshire averages.

Flat roofing calls from Box are predominantly on rear extensions of the period and modern fringe properties. The By Brook valley's moisture retention means flat roofs here accumulate moss and algae faster than on drier, higher ground — accelerating felt surface degradation. We replace with GRP as standard, which is moisture-resistant and easy to treat for biological growth.
Conservation area and AONB designations in Box don't typically constrain rear flat roof replacement, but visible flat roofs on listed buildings may need prior approval. We confirm planning status during the free survey before any specification is agreed.

GRP fibreglass carries a 25-year material guarantee and significantly outlasts felt. It's seamless once cured, handles thermal cycling well, and doesn't suffer the joint failures common on felt. We recommend GRP over re-felting in almost all cases.
A standard single-storey extension flat roof up to 25m² is typically completed in one day. Larger or more complex roofs may take two days. We give an accurate timeline in every quote.
Yes — garages, outbuildings and garden buildings are a regular part of our flat roofing work in Box. Same specification and 25-year guarantee as domestic extensions.
If the roof is more than 20 years old and showing active failure, replacement is almost always more cost-effective than repair. We survey and advise honestly — we won't recommend replacement if targeted repair genuinely meets the situation.
