Roof Valley Leak: A Problem that Needs Professional Attention

Roof valley leaks require professional repair service. It is very complicated to fix damages on closed valleys because it will require the removal of surface shingles and reinstallation of metal roof flashings that connect the roof to the walls. If a leak develops in the valleys of your roof, you can call roof repair expert and our roofing experts will quickly inspect the causes of leaks and perform the necessary repairs.

Common Causes For Roof Valley Leak:

  • Improper installation of roof nails to pipe flashing
  • Roof nails exposed in flashing to close to roof vent pipe.
  • Improper sealed around pipe collar or no sealant.
  • Leak originating from a different area and finding an
    opening at the vent pipe.

Roof valley leaks can be caused by improperly placed roofing nails. Roof nail fasteners should not be placed too close to the center line of the valley. The tension created and indentations surrounding the installation of fasteners may crack open some parts of the valley. These cracks are usually not visible when you inspect your valley.

This is because the metal fasteners are located underneath the roof shingles. To repair the cracks we will have to remove the overlaying shingles on your roof valley. Roof nail fasteners would have to be pulled out and the sealed with adequate roof sealant. The fasteners then would have to be placed a little wide outside the center line of the valley in order to avoid recurrence of the problem. The shingles then would have to be refastened over the valley edges to ensure adequate waterproofing.

Another source of a valley leak could come from the shingles. Normally, shingles provide adequate protection. Shingles in good condition ensure that the connections in your roof valley system will be water tight. Deteriorated, cracked, blown out, curling, and broken shingles can cause innumerable damage to the underlying membrane of the valley.

Water will definitely seep through broken shingles. Clawing shingles will also accommodate backing up water. Blown out roof shingles on the other hand will definitely expose the inner roofing materials to rain or snow. All these will cause leaks and the best way to solve these problems is to call roof repair expert.
