Roof Overlay Construction Procedure
1. Dismantling Existing Metal Sheets
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 metal.
2. Installing Roofing (Waterproof Sheet)
This underlayment boasts the highest quality, unmatched in both waterproofing and durability. By sandwiching a modified asphalt layer between non-woven fabric and base paper, it fully demonstrates the inherent performance of modified asphalt. The expected durability is about 30 years!
As a secondary waterproofing measure, if the roofing is properly installed, there will be no leaks! We will ensure it is firmly applied to prevent it from blowing away.
Since there are various durability periods and characteristics for roofing sheets, it is important to choose a roofing sheet that matches the durability of the new roof and the roof slope!
3.Accessory Processing (Curly Patterns and Eaves)
The metal fittings at the ridge are our company’s original integrated waste board ridge base. It has a durability of approximately 30 years and provides high wind resistance.
4. Main Construction (Aijii Industry / Super Galtect)
Once the installation reaches the ridge, we will install the necessary materials to secure the ridge flashing called a “kanban.” We offer three types of kanban: cedar, resin, and Galvalume steel, and this time we used Galvalume steel!
Galvalume steel offers three times the durability compared to cedar! Unlike resin or cedar, it does not crack, providing peace of mind!
Our original integrated waste board ridge base made of Galvalume steel is highly durable, has 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 Super Galtect ridge base!
5. Ridge Flashing Processing & Sealing at Various Locations
We use rust-resistant stainless steel screws with waterproof washers for secure fastening!
Unlike nails, screws with washers are less likely to pull out
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 critical area of the roof.
6. Cleaning
After the
We will also wipe away any footprints left on the roof to ensure it looks 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 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 parts 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 also has soundproofing properties, reducing the sound of rain. Being lighter than other roofing materials, it minimizes the sway during earthquakes, providing 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, receiving significant attention!
