How it works

  1. Describe the roof

    Type of covering, what is wrong and approximate sizes. The drawing shows you what you are telling us.

  2. We look at your case

    We point you to the right guide for your problem, what you can expect and what to ask whoever does the work.

  3. Decide calmly

    With prices that have a source and a date, compare quotes and choose. We do not do roof work.

Where a roof fails

A tiled roof has several layers. Water only gets in when more than one fails at the same time. Knowing which saves unnecessary work.

abcdefg
Section of a tiled roofDiagram, not to scale
  1. a
    Tiles

    They break with frost, wind or people walking on them. One tile out of place is enough to let water in.

  2. b
    Battens

    The battens hold the tiles. With damp, the wood rots and the tiles slip.

  3. c
    Underlay

    The second barrier against water. Many old roofs do not have one.

  4. d
    Insulation

    Without it, heat leaves through the roof in winter and comes in during summer.

  5. e
    Structure

    Timber, concrete or metal beams. Dark stains or sagging beams call for a specialist.

  6. f
    Gutter

    When it is full of leaves, water overflows and runs down the wall.

  7. g
    Ridge

    The tiles on top sit on mortar, which cracks over time.
