Roof Repair (Ridge Cap) Replacement Work
1. Existing Ridge Cap Dismantling

We will remove the old ridge cap and the internal wood blocking. Care is taken not to break the roofing material during this process.
Upon removing the side ridge cap, there is internal wood blocking. The existing wood blocking had a significant gap. That’s not good!
This is the state after dismantling the ridge. The hole in the middle is where the ventilation ridge was installed. It serves to expel moisture and heat from the attic!
2. Installation of New Wood Blocking
We will install new wood blocking. There are also resin wood blocks available, which are resistant to corrosion (such as Tough Mock and Eco Lumber).
3. Processing and Installation of Ridge Cap and Side Flow Ventilation Ridge (Completion)

The installation of the ridge cap and ventilation ridge is complete!
Procedure for Rain Gutter Replacement
1. Dismantling Existing Eaves Gutter

The center was distorted due to snow damage. We will remove the eaves gutter and brackets.
2. Installing New Eaves Brackets
We will install new eaves brackets. When installing the brackets, we will use kite string or chalk lines to set the slope of the rain gutter, as the slope is crucial!
It is important to note that due to the fascia (where the eaves brackets were attached) or the building’s distortion, even if the slope is set with the brackets, there may be backflow. It is essential to check the slope with a level against the fascia before attaching the brackets!
3. Installing the Eaves Gutter
We will install the new eaves gutter and downspout!
4. Connecting to Existing Downspout
We will connect the existing downspout to the eaves gutter.
5. Clean Up and Completion!
That’s all!
Type of Rain Gutter Used
The rain gutter installed this time is a type called Panasonic U105. It seems to be commonly used in relatively new buildings. Like the Panasonic PC50 that we often use, it has a steel plate inside!
I’m glad we were able to complete the construction safely this time!
The Necessity of Roof Work (Roof Repair) and Maintenance Schedule
◇ Necessity of Roof Work and Maintenance
・Necessity and Purpose of Roof Work
The roof directly receives damage from rain, wind, and ultraviolet rays, and problems such as cracks and leaks surface over time. By carrying out roof work, we enhance the durability of the building and maintain a comfortable living space. Additionally, improvements in energy efficiency can be expected. For example, using highly insulating roofing materials can lead to reduced heating and cooling costs.
In terms of long-term cost performance, roof work can be considered an important investment.
・Schedule for Roof Work (Roof Repair)
Depending on the type of roofing material and the local climate, in general, roof work (roof repair) is carried out every 10 to 15 years. After that, it is advisable to inspect every five years and carry out repairs or painting as necessary. Regular maintenance can help detect small deterioration or damage early, reducing the risk of large-scale construction or repairs.
However, this is just a guideline, and it can vary depending on the material of the roof and environmental conditions such as high humidity, strong winds, and snowfall. Under severe weather conditions, more frequent checks may be necessary. Additionally, roof work (roof repair) involves working at heights, so it is advisable to hire a professional contractor.
Post-Construction Maintenance
◇ Importance of Post-Construction Maintenance
Maintenance after exterior painting and roof repair is a crucial factor in extending the lifespan of the house. Neglecting maintenance can lead to the newly painted exterior and repaired roof deteriorating quickly, resulting in the risk of incurring high costs. The exterior walls and roof of the building are constantly exposed to harsh natural environments such as rain, wind, ultraviolet rays, and temperature changes. Regular maintenance can minimize damage and maintain the beauty and comfort of the home. Furthermore, it can help avoid large-scale repair work and the associated significant expenses.
◇ Maintenance Methods and Frequency
One effective method for post-construction maintenance is inspections by specialized contractors. This allows for the early detection and repair of even minor damages. The recommended maintenance frequency is generally exterior painting every 5 years and roof repairs every 3 years. This is merely a guideline and may vary based on local climate conditions and the structure of the house.
