Can Water Get Under Kickout Flashing?

September 6, 2024

While kickout flashing is meant to divert water into the gutters, improper installation can allow water to penetrate behind the material. Protect your client’s exterior cladding with proper installation of flashing from Kickout Flashing by PBZ.

Why Can Water Get Under Roof Flashing?

Water can divert under roof flashing and damage the roof and other structures in cases like these:

  • Improper installation: Installation at the wrong angle or in the wrong location won’t divert water as intended. The original installer may have made other errors, such as not clearing the roof of debris before putting in the kickout flashing.
  • Incorrect sizing: If kickout flashing is too large or small, it won’t lay correctly between the roof and the wall. 
  • Inadequate or incorrect sealing: Kickout flashing needs sealant to stay watertight and prevent water from seeping under.
  • Storm damage: Weather conditions such as high winds or flying debris can compromise kickout flashing. Check these components during a post-storm inspection.
  • Low-quality materials: Materials like galvanized steel may rust over time, creating holes that allow water where it shouldn’t go. Kickout flashing and its fasteners should be made of corrosion-resistant material.
  • Adjustments by homeowners: Homeowners may not understand the importance of kickout flashing and try to remove theirs or minimize the appearance by cutting it shorter.
  • Poor maintenance: Just as homeowners should inspect and clear their gutters, they should examine their kickout flashing. Checking for debris and clearing buildup keeps water from sitting and getting under flashing.

How to Properly Install Kickout Flashing

This flashing goes above the gutter where the roof meets a wall. Install it so it extends 4 inches or more up the sidewall and sits at a 110-degree angle. Choose flashing made of corrosion-resistant materials, like aluminum products from Kickout Flashing by PBZ, for dependable results.

Signs of Damaged Kickout Flashing

If you notice a client has damaged roof flashing with rust or small holes, it’s time for a replacement. Worn roof flashing can cause water damage and related issues such as:

  • Stained fascia boards
  • Mold on exterior walls
  • Damage to the siding, like discoloration, rotting materials or peeling paint
  • Leaks inside the home

Because kickout flashing wasn’t a requirement under the International Residential Code (IRC) until 2009, older homes may not have this essential roofing component. You can add kickout flashing to an existing roof to follow the code requirements and prevent roof damage for your client.

Old, worn sealant can also let water flow where it isn’t supposed to. Roof sealant can last from 10 to 20 years, so if your client’s roof flashing does not appear sealed, it may be time for a new installation.
