You may already be aware, but thanks to a permanent relaxation in planning rules homeowners now have the freedom to add an extra space to their home in the form of a single storey extension without the need for planning permission. Due to this change, many builders and roofers are overflowing with requests to create such extensions. After all, given the current climate, it’s much more favourable to ‘improve’ as opposed to ‘move’! Interest rates and mortgages are fluctuating and are becoming increasingly unpredictable, which may make you feel a little uneasy about making any drastic decisions. So, if you don’t want to be caught up in the headache of selling your home and uprooting, perhaps an extension might be a better option for you?
One of the major factors to consider when planning an extension is the type of roofing as single storey home extensions typically have a lower roof pitch. Let’s take a closer look at the considerations for low pitched roofing…
What are the key low pitched roof considerations?
Whilst the rules have been relaxed, there are still some considerations that need to be thought of when planning your extension…
You’ll still need to match your existing roof tiles
Now this could be tricky if the material in question is no longer available and it might mean you need to seek an alternative solution to replace your existing roof and cover the new extension too. So make sure you check this before you go ahead and purchase the new roofing for your home extension. The last thing you’ll want to do is have an unexpected cost and buy two lots of roofing, blowing your project’s budget.
You will need to check the minimum pitch of the roof tiles you choose
Don’t get caught out here! You might think ‘will one degree make a difference?’ and the answer is, yes, absolutely. You need to tread carefully and ensure you aren’t tempted to tile below the manufacturer's recommended pitch as this could end up causing you a major headache in the future. Not only can this totally invalidate any guarantee you have with the supplier, it may also result in a roofing system that doesn’t offer full weather protection, and who wants to be dealing with leaks during the winter months? Another costly price to pay when you have only just paid out for the extension itself - especially if the leaks reach through to the inside of your newly, beautifully decorated space!
Rain, rain, go away!
Another key consideration when it comes to extending with a low pitched roof is water run-off. It’s quite common that a low pitched roof will have to deal with the inconvenience of water running off from a higher, larger roof. Therefore, an adequate system must be in place to ensure it is able to effectively run off into a sufficient drainage system, which will also need to be able to to cope with the amount of water coming from both the immediate roofing and the higher, larger roof above. Without these in place…you guessed it, more costly leaks and water damage. As you can see, low pitched roofing does come with various obstacles, headaches, and the high risk of costly water damage, but the GOOD news is, here at Onduline, we’ve made life a bit easier for you, or perhaps, your roofing contractor with our ISOLINE LOW LINE roofing system.
