Valley Replacement

When to Replace A Roof Valley

When we are on your roof repairing the ridge cap repointing on your tiled roof, we will take a look at the valleys as well for you. If they are showing any sign of rust, it's best to change the valleys before the ridge capping work.

Otherwise, if the valley is changed after the ridge caps are repointed - the ridge capping work will have to be done again!

If the rust is too bad to repair, we will recommend replacing it with new Colorbond valleys that are colour matched to the roof tiles. We prefer installing colour matched valleys as they look good, and last longer - at no extra cost to you.

We can replace worn or rusted valleys, flashings, box gutters, worn metal skillions, and skylights.

We use and recommend Roof Protect industrial roofing membrane.

Valley Repairs on the Gold Coast

Most roofs have several valleys. A valley is that section of your roof where two slopes join at an angle.

Rusted or damaged valleys are some of the most common causes of leaks in your roof.

Valleys should normally last well over 20 years, but their life span is shortened as corrosive debris builds up, especially if your roof is under trees. In this case, the valleys will need frequent cleaning and rust-proofing to extend their life and prevent leaks.

If your valleys have started to rust, an inexpensive solution is to prepare the surface and paint it with a special cold galvanising paint that will slow the rust and extend the life of your valleys for years to come.

Galvanising paint is a cheaper option because the ridge capping won't need to be cracked in order to replace the valley.
