Roof Overlay Construction Procedure
1. Demolition of Existing Ridge and Snow Stops
The durability of wooden purlins is about 10 to 15 years. Once the durability period is exceeded, corrosion and discoloration occur, leading to the detachment and scattering of the ridge flashing.
2. Installation of Roofing (Waterproof Sheet) andAccessory Processing (Eaves, Gable, Valley)
Tadi Self Cover is the ideal roofing sheet for overlay methods on fragile slate materials such as non-asbestos roofing. As a secondary waterproofing measure, if the roofing is properly installed, it generally will not leak. We will ensure it is securely applied to prevent it from being blown away by the wind.
Since there are various durability periods and characteristics for roofing sheets, it is important to choose a roofing sheet that matches the durability period of the new roof and the roof slope!
The metal fittings at the ridge are our original integrated waste board ridge base. With a durability of approximately 30 years, it is a ridge base with high wind resistance.
3.Main Construction (Aiji Industrial / Super Galtect)
After processing the
Once the installation reaches the ridge, we will set up the necessary materials to secure the ridge board known as the kanban. We offer three types of kanban: cedar, resin, and galvalume steel, and this time we used galvalume steel!
Galvalume steel is expected to have three times the durability compared to cedar! Unlike resin and cedar, it does not crack, providing peace of mind!
Our original integrated waste board made of galvalume steel for the ridge base is highly durable with excellent fixing power and wind resistance!
Even if rainwater enters from the ridge, it has a mechanism to discharge rainwater to the outside, demonstrating high waterproofing performance!
It is perfect for the ridge base of Super Galtect!
4. Ridge Cap Processing and Sealing at Various Locations
We will process and install the ridge cap
We will use rust-resistant stainless steel screws with waterproof washers for fixing!
Screws with washers are less likely to come loose compared to nails,
securing the ridge cap firmly to the kanban!
Although it is not visible after construction,
installing a face plate inside the ridge cap
enhances waterproofing!
It firmly protects the ridge, which is a critical point of the roof.
5. Cleaning
After the
Additionally, we will wipe away any footprints left on the roof to ensure it is clean.
About Roofing Materials
The roofing material used is Ai-Gi Kogyo / Super Galtect. Super Galtect comes with a 15-year paint warranty and a 25-year hole warranty from the manufacturer, along with a 10-year construction warranty from our company! Additionally, it is made of SGL steel, which is resistant to rust.
The insulation material is tightly applied from edge to edge of the roofing material, creating a metal sheet that integrates the steel plate and insulation. When installed, insulation is applied even to the areas where the roofing materials overlap, and the surface is coated with a high heat-reflective paint, allowing for a cool summer and a warm winter.
Moreover, it has soundproofing properties, reducing the sound of rain. Being lighter than other roofing materials also minimizes the sway during earthquakes, providing earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and our company’s construction results show that Ai-Gi Kogyo’s Super Galtect is the most popular and highly regarded!
