Do I need a new roof?
Not 100% sure whether your roof needs replacing?
Here are some of the key signs that a roof replacement should be on the cards.
Water damage
If you notice staining on your interior walls or the ceiling, then there's very likely a leak.
Head up into the loft and look to see if you can spot the leak and confirm it's the roof.
Misshapen, sunken or missing tiles
Think that your roof doesn’t look quite right? This could be due to structural sagging or missing roof tiles.
Either way, it's worth getting your roof checked by a professional.
Worn-looking chimney flashing
Flashing is the grey-looking material that protects roof joints. Over time, old rooftop flashing will wear, allowing rain into your home.
It could be time to review the entire roof structure if it looks patchy or peels away.
Moss and mould growth
Check the roof to see if there's a lot of moss and mould inside your home.
Streaks of light coming into the attic
This is a big telltale sign that your roof needs urgent attention.
Damaged or rotten underlay
Have you discovered the underlay in your roof, and is it damaged or rotting? This is another big sign that it's time for a new roof.
Your roof is over 20 years old
Just like any part of your home that’s exposed to the elements, your roof will be subject to wear and tear over the years.

Improved protection
A new roof gives you the peace of mind that your home will be protected from the elements.
Increased energy efficiency
A re-roof can maximise the efficiency of your home by retaining heat better. This means less energy used to heat your home and fewer pennies on your energy bills.
A facelift for your home
It’s hard to overstate the effect your roof has on how your home looks.
After years of use, tiles can become discoloured. Replacing tiles can bring your roof back to life and improve the look of your home.
Adds value
A new roof can add value to your home and increase the kerb appeal for future buyers
