Ridge Flashing Replacement & Nailing Board

Ridge Flashing Replacement

The replacement of ridge metal flashing involves the work of replacing the metal flashing installed at the ridge part of the roof with new materials.

Inside the ridge flashing, there is a nailing board that is used to secure the ridge flashing, and we will also replace the nailing board along with the ridge flashing.
Typically, the nailing board used during construction is made of cedar, so replacement of the ridge flashing or the internal nailing board is necessary every 10 to 15 years.

If the durability period is exceeded, the internal nailing board may begin to rot, leading to the risk of the ridge flashing being blown off, lifting, or deforming, which increases the risk of leaks.

Internal Nailing Board Replacement

Internal batten replacement involves reusing the ridge cap and only replacing the internal batten.
Kakeru Koumuten Co., Ltd. can also handle “batten only replacement.”
Since the ridge cap is reused, if it is deformed, the work cannot be performed, but costs can be reduced compared to a standard ridge cap replacement.

Ridge caps are usually made of Galvalume steel, but we offer three types of battens: Cedar, Resin, and Galvalume steel, each with different durability lifespans.

The durability lifespans are as follows:

Cedar batten … durability lifespan 10 to 15 years

Resin batten … durability lifespan 20 to 25 years

Galvalume steel batten … durability lifespan 30 to 35 years

Benefits of Ridge Cap Replacement

Here are three benefits of ridge cap replacement.

  1. Improved waterproofing: The ridge cap is a crucial element that covers the ridge of the roof and is considered a vital point of the roof. By replacing damaged or deformed ridge caps, waterproofing is enhanced. New ridge caps prevent rainwater intrusion and protect the interior of the roof from damage and leaks.

  2. Improved durability: New ridge caps are made of high-quality Galvalume steel and are resistant to deterioration and rust.

  3. Aesthetic enhancement: Old or rusty ridge caps can detract from the appearance of a building. Installing new ridge caps will beautify the building’s exterior and enhance its real estate value.

As evident from the benefits above, replacing the roof ridge cap is an important process that enhances the overall health and value of the building. It also leads to future cost savings, making regular maintenance the best approach.

Roof Ridge Cap Replacement Plan (Using Resin Battens)

・Roof ridge cap replacement (using resin ridge board)
Unit price per meter m/¥5000~
Materials used Ridge cap: Galvalume steel plate, Ridge board: Resin ridge board

The roof ridge cap replacement involves replacing the metal sheets installed at the ridge part of the roof with new ones.

This work is carried out to protect the roof and prevent leaks, while also enhancing the appearance of the building.

If a cedar ridge board is used, the cost can be slightly lower.

About the Ridge Tile Surface Plaster

Another process included in Kakeru Koumuten’s ridge construction plan is the ridge tile surface plaster. This process involves the application of a special coating material called Nanban plaster to the ridge tiles located at the ridge part of the building’s roof.

The price starts at 5,000 yen per meter, and the specific estimate will vary depending on the quantity and shape.

If the peeling plaster is left unattended, the foundation soil (Arakida soil) may wash away, increasing the risk of instability and collapse of the ridge. If applying the surface plaster is difficult, it may be necessary to carry out re-stacking work on the ridge.

Benefits of Ridge Tile Surface Plaster

Here are three benefits of applying ridge tile surface plaster.

  1. Improved Waterproofing: The application of ridge tile surface plaster uses a high-strength plaster called Nanban plaster, protecting the ridge part of the roof. This prevents the intrusion of rainwater, protecting the interior of the roof and the building’s structure from water stains.

  2. Enhanced Protection and Durability: The application protects the ridge tile surface, improving its durability over a long period. It reduces the impact of external factors and deterioration, extending the lifespan of the ridge part.

  3. Aesthetic Enhancement: The application of ridge tile surface plaster affects the building’s appearance as part of the exterior wall, and a beautifully finished ridge part enhances the overall aesthetics of the building.

The application of ridge tile surface plaster is an important process that protects not only the building’s appearance but also against rain leaks into the interior and damage, improving durability. This can extend the lifespan of the building and enhance its value.

Maintaining Waterproofing: The ridge area is where rainwater concentrates more than other areas, making waterproofing extremely important. If the waterproof materials or ridge metal deteriorate, the risk of leaks increases, so it is essential to maintain waterproofing through regular maintenance.

Extension of Lifespan: The materials in the ridge area are exposed to external environments and deteriorate over time. Through regular maintenance, old materials can be replaced, extending the lifespan of the roof. This can delay the need for major roof repairs.

  • Protection from Wind Damage and Typhoons: The ridge area plays a role in protecting the building from wind pressure and wind damage. Deteriorated ridge areas increase vulnerability to wind damage, raising the risk of building damage. Regular maintenance helps protect the building from wind damage, enhancing safety.

  • Maintaining Aesthetic Appeal: The ridge area also affects the appearance of the building. Rusted or deteriorated ridge flashing and paint can detract from aesthetics, worsening the overall impression of the building. Regular maintenance allows you to keep the appearance beautiful.

  • Preventive Measures: Regular maintenance can help detect and repair potential issues early! If small deteriorations or gaps are left unattended, they can eventually lead to severe leaks, increasing the likelihood of needing extensive repairs or replacements. Regular maintenance allows for preventive measures to be taken, preventing deterioration symptoms before they occur.

  • Cost Savings: Regular maintenance can potentially save money in the long run. By maintaining the roof, you can avoid major repairs, extend its lifespan with minor repairs, and reduce future costs.

  • Overall, regular maintenance of ridge work is essential for maintaining the lifespan and value of the building. With benefits such as ensuring waterproofing, extending lifespan, protection from wind damage, maintaining aesthetics, preventive measures, and cost savings, we highly recommend regular maintenance for those with any concerns.
