What the Weather does to Your Roof

Fortunately in the UK we experience mostly mild weather. It isn’t extremely hot, it isn’t extremely cold, despite how we feel most of the time!

Also, we don’t experience any crazy natural phenomena like blizzards, hurricanes or any other extreme weather. 

However, most every climate affects the roofs in their vicinity differently. England is no different and Cambridge is no different further to that. 

As ever, it is important to carry out maintenance if you want a really lasting product over your head. It will save you from costly roof repairs and even more costly roof replacements.

The weather in England is pretty predictable. We have lovely cool temperatures and clear blue sky during Autumn and Spring. Then the sporadic heat in the Summer, mixed with those cool icy nights in the Winter. Unfortunately, these seasonal changes are going to have an impact on your roof. Let alone the good old, consistent rain-water we get in England! 

Ideally, you would have a seasonal routine checklist to maintain your roof. Check your slates, tiles, edges, flashing… Check your gutter, chimney, the inside and outside of your roof. Basically look at it all at least a few times a year! We don’t want to say check it every day, like we always say, but you can do seasonal, right?!

Your roof in Summer

Although our Summers are… Well, weak. To say the least. We still get some sun… So stay with me.

Believe it or not, the UV damage caused by the English sun DOES affect your roof. As your roof is the blockade between you and the sun… it absorbs all the UV. The rays dry out your wood under your tiles, causing them to shrink, bleach and potentially split. 

Your roofing tiles, after being exposed to the sun for a long period of time, like our recent good weather, can buckle and break and the join between your tiles can become weak too.

Fortunately, if you maintain your roof correctly, whether by you or us, you can survive many hot summers. You aren’t out of the game yet. Especially if your roof is new or not under ten to fifteen years old.

An old roof might start to cave under the pressure of the UV and other changes in the weather when your tiles and wood have weakened. A big storm all of a sudden is going to cause all sorts of problems! 

Thermal shocking 

Something which will deteriorate your roof is when the weather suddenly goes from that nice, rare Summers day… Then the sun goes down ant the temperature is quartered. The erratic change in temperature and moisture in the air can cause your roofing materials to expand and contract too quickly. Everything will become weaker and susceptible to damage.


Over time, and if you never get roofing maintenance or repairs, you might have moisture trapped within the ridges and support structure. With really hot temperatures, plus occasional downpours, mould can be encouraged to grow. You want to look out for it on top of your roof, as well as in your attic. Quell the growth early so it doesn’t spread and impact internal and external walls. 

Your roof in Winter

With Winter, we are dealing with more consistent rain, less heat, frosty, snowy and just all round cold days…


Rain is our biggest problem. The relentless rain becomes tiresome after a while, but you have to stay vigilant with your property. Check that your roof isn’t puddling or suffering from any kind of water damage, as this can lead to catastrophic problems down the line. 

Especially look after any flat roofs you might have. You don’t want puddling AKA water collecting then damaging the integrity of any structure. You can reason our article on extending the life of your flat roof here. 

Make sure to check your gutters and pipes so that there is no debris blocking the rain-water funnelling away from your home. 

Clear drainage is incredibly important. Not only do we want to move away the water we can see. We also don’t want to encourage our roof to become moist and soak up liquids. As we saw above, harsh weather changes, combined with moist roofing materials make for a bad, bad combo. 

Icy, cold winds! 

Our tasty, icy cold winds don’t help either. When strong and powerful, they can even start to move and disjoin tiles. There’s not a lot you can do about this, other than cross your fingers and pray to the weather Gods. You could, we suppose, pay close attention to your roof and ensure no tiles are loose. That way, everything will stay in tact. 

Wrapping up.

That’s it for now, hopefully that was insightful on how the weather can mess with our roofs!
