Five Things That Cause Damage to Flashings

The main purpose of roof flashings (barge cappings, apron flashing etc) is to seal potential entry points on the roof and then direct wetness away from it in order to protect and preserve the interior components of a building. Needless to say, flashings are crucial components of a roofing system, which is why they should be installed correctly at all times and protected from damaging elements and situations.

If you wish to preserve your roof flashings really well, it’s important to know the factors that cause damage to them. Five of the most common causes are provided below.

  • Incompatibility of the flashing to the material it’s attached to.

There are amateur roofers that actually make the mistake of using aluminium flashings against a brick chimney. While aluminium works well in many locations, it is incompatible with masonry of any type. The alkaline chemicals in mortar can corrode aluminium and it’s just a matter of time before flashings come loose from where they’re attached.

  • Excessive weight on the flashings.

The heavy weight of people visiting the roof (window washers, painters, smokers, HVAC technicians, et cetera) can be too much to bear for flashings and the roof valleys they’re attached to. If constantly subjected to heavy weight, the flashings can come loose and develop holes and tears.

  • Deterioration of the material it’s attached to.

If you install flashings on old roofing iron or a crumbly chimney, you can expect them to come off easily and get damaged in different ways. They can tear and develop cracks and holes since the materials they’re attached to morph in durability and size.

  • Shaking.

Anything that can shake the entire building structure – like earthquakes and groundwork – may cause damage to roof flashings. If there has been severe ground shaking, then you better inspect your roof flashings immediately to see if they withstood the movement and stayed put.

  • Neglect and abuse.

Neglecting to carry out regular maintenance and mistreatments of a roof are perhaps the most common of all causes of flashing damage. Not getting rid of debris that may be sharp can puncture holes into flashings when people accidentally step on them during a roof visit. Abuse, meanwhile, can come from window washers and painters that hang access equipment on the sides of the roof and kick flashings as they navigate the roof. Kicking flashings often leads to leaks.

To outwork these causes behind flashing damages, do consult a roofing specialist and implement their advice; this way, you can preserve not only your roof but also everything else it protects.
