Roof maintenance advice or programme? we can offer you advice on how to care for your roof or put together a programme maintenance schedule to cater your requirements!

Spotting roofing problems early can save you a fortune. Here are some of the telltale warning signs to look out for:

All Roofs

Moss, grass, plants, tennis balls, drink cans & bottles…yes we have seen it all on roofs, to prevent unwanted leaks we advise to make sure your roof is clean of all unwanted debris and plant life as they can lead to bigger problems further down the line.

Roof types

Most houses have pitched (raised) roofs covered in tiles or slate.

  • Tiles are commonly made out of cement or clay. Cement tiles should last 40-50 years. 
  • Slate is hard-wearing but rarely used because it's expensive. More slates than tiles are needed due to how they overlap. Reclaimed slates are cheaper.
  • Felt - Many outbuildings and garages, and some extensions, have flat roofs. Felt is the most common covering but newer materials such as fibreglass and PVC are now used.

What you should look for

Spotting these early warning signs can prevent more expensive problems.
Tiled/slate roofs

  • Damp or leaks may signal a cracked or slipped tile/slate.
  • If a tile/slate has blown off, it should be replaced quickly to prevent water from penetrating the felt underneath. Also, more tiles/slate can be dislodged in high winds if there is one missing.

Flat roofs

  • Cracks or splits round the edges.
  • Sagging – as water builds up boards can break under the weight.
  • Damp patches on the ceiling – the roof may have a tear.

Stand back and check your flat roof from the ground periodically. If you spot uneven lumps, repairs may be needed.


If you would like us to put together a programme for you to maintain your roofs we will give you a quote with optional times a year we will visit to maintain your roof.

While we are there we will inspect & take photographs of the roof for any defects or potential future problems and make you aware of this.

Before you carry out any maintenance works make sure you have a safe procedure in place to carry this out as working at heights is one of the biggest risks in construction industry; alternatively you could ring in the professionals,
