Quality, reliable roofing services in Surrey

Winter is coming. The last thing you want on a cosy autumn evening is a cold drip down your neck as you settle down in front of Strictly.

Water coming through the very part of your house that’s meant to keep you dry is every occupant’s worst nightmare. But the chances of your roof springing a leak varies widely depending on where you live in the UK.

We set out to discover exactly how widely, and which cities will have you reaching for the roofer’s number.

First we looked at data from the Met Office to rank UK cities by their average rainfall per year. The more rain, the quicker roofs wear out, and the more likely that pesky wet stuff is to find its way into your home.

We gave all 63 UK cities a score of 1 to 63 (1 being the most rainfall).

Next we investigated online search volume for related terms like “roof repair” or “leaking roof”. For this we used Google Keyword Planner, which gives you estimates of the numbers of people searching for the terms you’re interested in, which can be narrowed down to geographical area.

After we’d checked all the relevant search terms for each city, we adjusted for population differences by dividing their populations by their search volumes, to get a “demand average” score.

Then we ranked them by this score, to get another 1 to 63 list, lowest again being the “higher” score.

After that it was a simple case of adding together the scores to get an overall “leakiness” score. The lower the score, the higher the rainfall in a particular city, and the higher the demand for roof repairs.

While it was no surprise to see that cities from the North of England, and Scotland, in the top 10, who would have thought that the city with the leakiest roofs in the UK was…


In fact, Plymouth also made a high entry at number 5. Being down south doesn’t guarantee you the dry life. Maybe being close to the sea isn’t the best for roof health.

Meanwhile it was also not a shock that the least leaky cities were towards the southern end of our island, and generally fairly inland. If you don’t like leaks, Cambridge is the place to be.
