Roof Overlay (Cover Method) Construction Procedure
1. Dismantling 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 detachment and scattering of the ridge cap.
2. Roofing Installation (Waterproof Sheet) &Accessory Processing (Karakusa, Keraba,Valley,Ridge Base)
Tadi Self Cover is the ideal roofing sheet for the cover method of fragile slate materials, such as non-asbestos roofing materials. It serves as a secondary waterproofing layer, and as long as the roofing is secure, it basically won’t leak!
We will firmly attach 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 substrate to secure the ridge flashing. The batten we handle comes 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, making it a reliable choice!
Our original integrated waste board Galvalume steel ridge substrate is highly durable, has strong fixing power, and excellent wind resistance! Even if rainwater enters from the ridge, it has a mechanism to discharge rainwater to the outside, demonstrating high waterproofing performance!
4．Ridge Flashing Processing and Sealing at Various Locations
The screws used for fixing will be stainless steel screws with washers that are resistant to rust!
Unlike nails, screws with washers are less likely to pull out and firmly secure the ridge cap to the purlin!
Although it is not visible after installation, by attaching a face plate inside the ridge cap, waterproofing is enhanced! It effectively protects the ridge, which is a critical area of the roof.
5. Cleaning
About the Roofing Material
The roofing material used is the Super Galtect from Aijii Industrial. The Super Galtect comes with a 15-year paint warranty and a 25-year hole warranty, and we also provide a 10-year workmanship warranty!
Made of SGL steel plate, it is highly resistant to rust. The insulation material is tightly adhered 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 areas where the roofing materials overlap, and the surface is coated with a highly 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 lightweight 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 has the most installations of Aijii Industrial’s Super Galtect, making it highly sought after!
