Roof Overlay Construction Procedure
1. Demolition of Existing Ridge and Snow Stops
The lifespan of wooden purlins is about 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 (Eaves, Gable, Valley)
Tadi Self Cover is the ideal roofing sheet for overlay methods on fragile slate materials such as non-asbestos roofing. With the role of secondary waterproofing, as long as the roofing is properly installed, it generally won’t leak. We will ensure it is firmly 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 choose roofing sheets that match the lifespan of the new roof and the roof slope!
The metal fittings at the ridge are our original integrated waste board type ridge base. With a lifespan of about 30 years, it is a highly wind-resistant ridge base.
3.Main Construction (Aijii Industry / Super Galtect)
After processing the
Once the installation reaches the ridge, we will set up the necessary materials to secure the ridge board called “kanban.” We offer three types of kanban: cedar, resin, and galvalume steel, and this time we used the galvalume steel!
The galvalume steel is expected to have three times the durability compared to cedar! Unlike resin or cedar, it does not crack, providing peace of mind!
Even if rainwater enters from the ridge, it has a mechanism to discharge rainwater to the outside, demonstrating high waterproofing performance!
It is perfect for the ridge base of Super Galtect!
4. Ridge Cap Processing & Sealing at Various Locations
We will process and install the ridge cap
For fastening, we will use rust-resistant stainless steel screws with waterproof packing!
Packings screws are less likely to come loose compared to nails,
firmly securing 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 firmly protects the ridge, which is a critical part of the roof.
5. Cleaning
After the
We will 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 thoroughly 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 highly heat-reflective paint, allowing for a cool summer and a warm winter experience.
Moreover, it has soundproofing properties, which reduce the sound of rain. Being lighter than other roofing materials also minimizes the sway during earthquakes, contributing to 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, gaining significant attention!
