Which flat roofs are common in Cornwall?
Flat roofs in Cornwall sit on 1960s and 1970s link-detached houses with flat-roofed garages and porches, shops with flat-roofed rear stores below flats and 1930s semis with flat-roofed garages and kitchen extensions. 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. Approximate 1991–2020 regional averages based on Met Office data.
Building regulations in England
Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. Renovated roofs over heated rooms are insulated to around 0.16 W/m²K where that's feasible, and new extension roofs are built to 0.15 W/m²K. In Cornwall the application goes to Cornwall Council. More on the rules.
What does a temporary weatherproofing visit involve?
A temporary visit stops the water getting in until a permanent repair can be made. It is not the finished repair.
Depending on the weather and the damage, the team may clear a blocked outlet or gutter that is backing water up, fix a heavy-duty temporary sheet over the damaged area, weight or secure lifted membrane and trims, or apply a temporary seal to a split or open lap. Where a rooflight or upstand is the cause, they make it as weathertight as they safely can.
Before they leave, the team will tell you what they found and what they did. They may also be able to give you an early view of whether the roof looks repairable or is due for replacement. That is followed by a written quote for the permanent work.
How quickly can someone come out?
We send a team for a temporary weatherproofing visit as soon as one is available. We don't promise a set response time, because demand jumps after storms and we would rather give you an honest answer on the phone than a figure we can't keep.
When you call, we ask a few questions about the roof and the leak so we can judge how urgent it is and what the team will need. Height matters: a single-storey garage or extension can usually be reached with ladders and edge protection, while a dormer or second-floor roof may need scaffold or a tower.
Safety comes before speed. In high winds, lightning or heavy rain, a team may not be able to work on the roof safely, and the visit may need to wait until conditions ease. Your best protection in the meantime is to contain the water indoors, as above.

What causes a sudden flat roof leak?
Common causes are storm damage that lifts seams, edges or trims, outlets blocked by leaves so water backs up over upstands, and old felt cracking after a cold snap. Sometimes the cause is a wall or coping above the roof rather than the roof itself.
Why can't you give me an exact arrival time?
Because we would rather not promise a time we can't keep. Demand spikes after storms and safe working depends on the weather, so we send a team as soon as one is available and keep you updated.
Can I put a tarpaulin on my flat roof myself?
We'd advise against it. Getting onto a flat roof in bad weather is dangerous, and many roofs and rooflights are fragile. Contain the water indoors and call us instead.
