What Is The Deal With Gutter Flashing – Why Is It So Important? 

It may not sound crucial but having a proper functional gutter flashing system is important for a running roofing system. Flashing and gutter relationship helps identify the issues before they progress and become complex and cost a fortune.

Gutter Flashing

Gutter flashing is a component that acts as a waterproofer since its job is to divert the water from the roof to the gutters. It is a thin long carrier material made of aluminum or plastic, placed between the gutter and roofline. The position prevents the water from flowing behind the gutter.

Flashings have a standard size of 2×3 inches of 10 ft in length. The contractors have to customize the size according to the level of commercial building they are planning to construct.

Commonly, a flashing is made of aluminum, steel, or plastic, which is added underneath the layer like a roofline to the gutter. Its placement is best over the joints on the roof and wall.

Importance of Commercial Roof Flashing 

What makes flashing so important? Well, it acts as a seal between the roofline and gutters, preventing leaks and water dripping behind it. This would lead to serious damage to the part of the building present right underneath the roof.

Water seeping inside would cause structural damage, reducing not only the curb appeal but also the cost of the property. Flashing for gutters comes in very handy for the rain-struck areas for most parts of the year. Additionally, it makes the building aesthetically pleasing.

Maintenance of Roof Gutter Flashing 

Flashing is an integral part of the roofing system. Regular maintenance ensures its overall health and lasting. Flashings, after some time, get rusty, causing the nails to loosen up the shingles. But, it is inevitable to save flashings from all the external damaging factors. Heavy winds, storms, and rainfall episodes will take a toll on it. That is why it is important to have a good look for any impairments periodically.

  • It is set along the roof’s edge, which helps the water flow dripping away without damaging the building.

  • Corner Flashing
  • It is placed where the walls meet, roof to floor.

  • Continuous Flashing
  • A long piece of continuous flashing, installed between the vertical wall and roof slope.
