Roofs leaking causing damage

Roofs leaking causing damage

Leaking roof causing damage to a newly built house.

  • Consistent leaking from a roof valley to a 5 year old house causing rot to some roofing timber and part of the roof truss.
  • Although valleys are a very common point of water entry, this should not be happening in a 5 year old building.


  • Further leaking can usually be stopped by bedding of the valley tiles (tiled roof) or fitting additional flashing (metal roof).

Common areas for roof leaking to occur.

  • Box gutters.
  • Spinning roof vents.
  • Skylights.
  • Dome-lights.
  • Dormer windows.
  • Split level sections.
  • Vent pipes.
  • Roof tiles.
  • Flashings.
  • Roofs with no eaves.

Anything that extends through a roof.

What you need to know about roofs and leaking.

  • Never lose sight of the fact that every roof will leak at some stages, taking into consideration the severity of some storms.
  • Generally, consistent leaking is what causes serious problems, over a long period of time, but sometimes from a huge deluge of rain.
  • Exact source of leaking is often difficult or impossible to determine, unless observing at the time of leaking during a storm.
  • In some cases the source can easily be identified by checking the roof exterior then the roof interio.

Unfortunately it is often a case of trial and error to determine if a roof leak has been stopped.

What to do to avoid damage occurring from roofs.

  • Roof’s must be checked on a regular basis by a qualified person for maintenance, especially after a storm.
  • It is also important to check your ceiling linings for sagging and have them resecured or if necessary, replaced.

Warning about some roof restoration companies and their claims.

  • Watch out for companies or individuals trying to sell you their products.
  • Restoration of a roof cannot be 100% guaranteed against roof leaking.
  • Read their disclaimers.
  • Often their limited warranty is voided if someone has been on the roof to check it out, read the fine print!

I would recommend contacting a qualified roofing plumber or a roof tiler.
