Should you get a new rooflight when you replace your roof?
Deciding whether to get a new rooflight when you are replacing your roof can be a tricky decision, as can deciding which rooflight you need.
You can either keep your existing rooflight and reflash it, or replace it with a new one. Although keeping your current rooflight may appear to be the more cost effective option, this may not be the case once you take into account how reliable the end result will be.
Here are a few things to consider when making your decision:
How long before you’ll need a new rooflight
If you are experiencing any leaks or condensation then you probably need a new rooflight anyway. You may consider fixing rather than replacing your rooflight but the cost involved means you are better off paying extra to get a new one instead.
It’s also worth considering how long the seal on your rooflight is likely to last. If it’s not going to last much longer, that’s a good sign you need to replace your rooflight.
How long before the warranty runs out
If your warranty is about to run out, then it’s not worth keeping your existing rooflight.
Getting a new rooflight, with a new warranty, means your two warranties will be synchronised, so you can do any future work at the same time.
Risk of leaks and breaking the seal
Re-roofing is bound to disturb the area around your rooflight and could damage it too.
Reflashing can also be risky and increase the chances of breaking the seal, or causing a leak. Such damage could invalidate your warranty, so you’ll end up needing to pay for a new rooflight anyway.
Benefits of the latest technology
If you bought your rooflight a while back, there’s likely to be new technology that’s emerged since then.
Re-roofing is a good opportunity to upgrade your rooflight, so you can take advantage of the latest technology.
You can get much more energy efficient rooflights, which will help keep your home warmer in winter and save money on your energy bills. You can also get handy features like a rain sensor that triggers your window to close automatically and keep your home dry in wet weather.
Given the risk involved in reflashing, we generally advise replacing old rooflights when you do re-roofing work.
You’ll save money in the long run and minimise the risk of damage.
