The next time you step outside your house, take a second to look up and inspect the condition of your roof because we are about to reveal how to tell when a roof needs replacing.
The good news is it doesn’t require a long pair of ladders and a head for heights. Many problems with roofs can actually be identified from the ground.
Only if you spot cause for concern will you need to ask a specialist to go up and take a closer look.
So, with that in mind, here is our guide on how to tell when a roof needs replacing:
The ridge is the very top of the roof where the two (or more) sides meet. It usually runs the full width of the roof. If this looks particularly uneven, twisted, or curves upwards or downwards, it could indicate that it’s time to call in the roofers.
An uneven ridge may just need the tiles re-laying if it’s particularly old. However, a bowing or sagging ridge could indicate some structural problems that will need the advice of a structural engineer.
A healthy ridge should be straight and level the whole way across.
A few missing roof tiles shouldn’t be too concerning, they’ll need replacing but shouldn’t mean the whole roof needs replacing.
However, if a significant number of tiles are cracked, chipped, or missing, it may be more cost-effective to replace the entire roof rather than repairing the tiles one by one.
If your roof has a significant amount of moss growing on it, it could be causing issues to your roof structure.
The moss has a tendency to grow between the gaps of tiles, gradually forcing them apart and creating openings where water and other debris can penetrate.
When checking your roof, don’t just look up! The ground can have clues too. If you are finding bits of mortar around the edges of the building or in the guttering, the chances are they came from your roof.
They may signify that some repointing is necessary but could also be the first signs of a roof needing to be replaced.
Heading back inside, if you notice damp patches on the ceiling or upper walls of rooms on the top floor of your property, that could indicating a leaking roof.
Try to trace the cause of the damp back to its origin, you may need to enter the loft space (if possible) to do this.
Pitched roofs are usually built with a fabric underlay beneath the tiles. If you head up into your loft space you should be able to identify the underlay pretty easily.
Check that the underlay appears in good condition and is not deteriorating in any areas.
While you’re in the loft space during the day, turn off the lights. If you see any daylight coming in through the roof then it indicates there are gaps or holes in your roof that will need attention.
Damage To Flat Roofs
Flat roofs are commonly used for extensions and other add-ons that weren’t part of the original fabric of the building. Because of the nature of flat roofs, water will tend to sit on on the roof for a little while after a period of rain.
This is not usually too much of a concern, but, if the water is taking more than two days to disappear, it could be a sign your flat roof needs replacing.
Other things that indicate a flat roof is ready to be replaced include cracking of the roof or loose roof felt.
How To Tell When A Roof Needs Replacing – Summary
As you’ve read, there are a number of things you can do to check the condition of your roof without having to even touch a pair of ladders.
Knowing how to tell when a roof needs replacing is a good skill to have as it means you’re more likely to spot issues early, and that can save you considerable money when it comes for paying for repairs.
Just ensure that if you do spot a potential problem that you call in a suitably qualified expert to take a look.
