Roof Overlay Construction Procedure
1. Demolition of Existing Ridge, Purlin, and Snow Guards
Exceeding the durability period can lead to decay and distortion, resulting in the dislodgment or scattering of the ridge flashing.
2. Installation of Roofing (Waterproof Sheet)
Tadi Self Cover is the ideal roofing sheet for covering fragile slate materials, such as non-asbestos roofing. It serves as a secondary waterproofing layer, and as long as the roofing is properly installed, it basically won’t leak!
We will securely attach this to prevent it from being blown away by the wind. Since there are various durability years 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．Accessory Processing (Karakusa, Keraba, Valley, Ridge Underlayment, etc.)
4．Main Construction (Aijii Industry / Super Galtect)
At the ridge, we will install the necessary ridge underlayment to secure the ridge flashing. We offer three types of ridge underlayment: 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 made of Galvalume steel
is highly durable, has strong fixing power, and excellent wind resistance!
Even if rainwater seeps in from the ridge,
it has a mechanism to discharge rainwater to the outside,
demonstrating high waterproofing performance!
It is ideal for the Super Galtect roof base!
5．Ridge Cap Processing and Sealing at Various Locations
The screws used for fixing are stainless steel screws with washers that are resistant to rust!
Unlike nails, screws with washers are less likely to come loose,
and securely fix the ridge cap to the purlin!
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.
6. Cleaning
Additionally, we will wipe away any footprints that may have appeared on the roof to keep it clean.
About Roofing Materials
The roofing material used is the Super Galtect from IG Kogyo. The 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 from SGL steel plate, it is highly resistant to rust. The insulation material is thoroughly applied from edge to edge of the roofing material, creating a metal plate that integrates both 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 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 the Super Galtect from IG Kogyo is the most frequently used in our construction projects and is gaining significant attention!
