Roof Overlay Construction Procedure
1. Demolition of Existing Ridge and Snow Stops
The lifespan of wooden purlins is approximately 10 to 15 years. Once the lifespan is exceeded, corrosion and discoloration occur, leading to the detachment and scattering of the ridge flashing.
2. Installation of Roofing (Waterproof Sheet)Installation of Accessories (Curlicue, Eaves, Valley)
Tadi Self Cover is an ideal roofing sheet for the overlay method 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 lifespans and characteristics of roofing sheets, it is important to select roofing sheets that match the lifespan of the new roof and the roof slope!
Before the installation of the main roof body, we will process and install components such as the eaves, decorative patterns, and valleys. The components used will be the genuine parts of Galutect made from SGL steel plate!
The metal fittings at the ridge will be our original integrated waste board ridge base. It has a durability of approximately 30 years and provides high wind resistance. [/chat]
3.Main Construction (Aiji Industrial / Super Galutect)
Once the installation reaches the ridge, we will set up the necessary materials to secure the ridge metal, known as the “kanban.” We offer three types of kanban: made from cedar, resin, and galvalume steel, and this time we used the galvalume steel version!
The galvalume steel version is expected to have three times the durability of the cedar version! Unlike resin or 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 strong fixation and excellent wind resistance!
Even if rainwater enters from the ridge, it is designed to discharge rainwater to the outside, demonstrating high waterproof performance!
It is perfect for the ridge base of Super Galutect!
4. Ridge Metal Processing & Sealing at Various Locations
We use rust-resistant stainless steel screws with waterproof washers!
Unlike nails, screws with washers are less likely to come loose
and securely fasten the ridge cap to the underlying board!
Although it’s not visible after installation,
installing a face plate on the inside of the ridge cap
enhances waterproofing!
It effectively protects the ridge, which is a critical area of the roof.
5. Cleaning
After the
We also wipe away any footprints left on the roof to keep it clean.
About Roofing Materials
The roofing material used is Ai-Gi Kogyo / Super Galtect. Super Galtect comes with a 15-year coating warranty and a 25-year perforation 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. During installation, insulation is applied even to the parts where the roofing materials overlap, and the surface is coated with a highly heat-resistant paint, allowing for a cool summer and a warm winter experience.
Moreover, it also has soundproofing properties, reducing the sound of rain. Being lighter than other roofing materials, it minimizes the sway during earthquakes, providing additional earthquake resistance.
It excels in finish, durability, insulation, soundproofing, and wind resistance, and our company’s construction achievements show that Ai-Gi Kogyo’s Super Galtect is the most popular choice, receiving significant attention!
