Roof Overlay (Cover Method) Construction Procedure
1. Demolition of Existing Ridge and Snow Stops
The existing ridge base is made of cedar, which has a durability of about 10 to 15 years.
Exceeding the durability period can lead to corrosion and discoloration, resulting in the ridge cap coming loose or being blown away.
2. Roofing Installation (Waterproof Sheet) &Accessory Processing (Karakusa, Keraba, Valley)
We will firmly adhere this 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 of the new roofing material and the roof slope!
3.Main Construction (Aijii Industry/Super Galtect)
The roofing material will be secured with stainless steel renovation screws!
At the ridge, we will install the necessary ridge base to secure the ridge cap. The boards we handle come in three types: cedar, resin, and Galvalume steel, and this time we used Galvalume steel.
Galvalume steel is expected to have three times the durability of cedar, and unlike resin or cedar, it does not crack, providing peace of mind!
Our original integrated waste board Galvalume steel ridge base is highly durable, has strong fixing power, and excellent wind resistance! Even if rainwater enters from the ridge, it is designed to discharge rainwater to the outside, demonstrating high waterproofing performance!
4.Ridge Cap Processing and Sealing at Various Locations
The screws used for fixing are rust-resistant stainless steel screws with washers!
Packings with screws are less likely to come out compared to nails, securely fixing the ridge flashing to the underlying board!
Although it is not visible after installation, adding a face plate inside the ridge flashing enhances waterproofing! It firmly protects the ridge, which is a critical part of the roof.
5. Cleaning
About Roofing Materials
The roofing material used is Aijii Industrial’s Super Galtect. Super Galtect comes with a 15-year paint warranty and a 25-year hole warranty, and we also provide a 10-year construction warranty!
Made of SGL steel plate, it is resistant to rust. Insulation material is thoroughly applied from edge to edge of the roofing material, creating a metal plate 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. Additionally, it has soundproofing properties, reducing the sound of rain.
Moreover, it is lighter compared to other roofing materials, which reduces the sway during earthquakes, making it a good earthquake countermeasure. It excels in finish, durability, insulation, soundproofing, and wind resistance, and our company’s construction results show that Aijii Industrial’s Super Galtect is the most popular and highly regarded!
