Roof Overlay (Cover Method) Construction Photos
1. Existing Roof Material Demolition
2. New Sheathing Installation
3. Installing Roofing (Waterproof Sheet)
It is made of a delayed adhesive modified asphalt roofing material, which is said to have double the durability of regular asphalt roofing.
As a primary waterproofing measure, if the roofing is properly installed, there will be no leaks!
We will ensure it is securely attached to prevent it from blowing away!
4. Fabrication of Accessories (Kera and Curved Metal)
The materials used for the accessories are galvalume steel.
5. Main Construction (Inagaki Shouji/Hiranbee)
After processing the
Once we have installed it up to the ridge, we will place the necessary materials for fixing the ridge cap, known as the kanban. The kanban can be made of cedar or resin, and this time we used a resin type!
The resin type is expected to have twice the durability compared to the cedar type!
6. Processing of Ridge Cap and Sealing at Various Locations
Next, we will process and install the ridge cap
We use stainless steel nails and screws that are resistant to rust for fixing!
7. Cleaning
We will clean up any debris that has fallen onto the balcony or rain gutter. We will thoroughly remove items like nails and metal scraps that could cause injuries. We will also wipe away any footprints left on the roof to keep it clean![/chat]
About the Roofing Material
The roofing material used is Hiranbee 220 from Inagaki Shouji.
Hiranbee 220 comes with a manufacturer warranty of 15 years for the coating and 25 years for perforation.
For re-roofing and overlaying, we also provide a 10-year construction warranty!
If there are any leaks within 10 years, we will make repairs free of charge.
It is made of Galvalume steel, which is resistant to rust.
The shaped panels are treated with iris folding and wave processing to prevent distortion and enhance strength, as well as improve rain drainage and aesthetic effects.
Additionally, it excels in finish, durability, sound insulation, and wind resistance, and is lightweight compared to other roofing materials, which reduces the sway during earthquakes, making it a good earthquake countermeasure.
In this overlay (cover) construction, the roof becomes double-layered, which increases weight, but Hiranbee is a lightweight roofing material, making it suitable for overlay (cover) construction.

What is the Roof Overlay (Cover Method)?
The roof overlay method involves leaving the current roof almost as it is and placing a new roof on top of it, effectively covering it.
Literally, it is a method of covering a roof with another roof. Therefore, the roof becomes double-layered. Since the roof is laid over, it is also referred to as “overlapping roofing.”
Advantages of the Overlay Method
Since a “new roof” is placed over the “current roof,” demolition work is almost unnecessary, meaning that very little waste is generated.
This is the biggest feature and leads to various advantages.
The only parts that require demolition and waste disposal are the ridge flashing, so compared to re-roofing, the cost is lower.
In 2004, regulations regarding the concentration of asbestos in raw materials were changed (for details, please refer to the Ministry of Health, Labour and Welfare’s website).
Building materials used in constructions before 2004 may contain asbestos. Asbestos-containing materials are difficult to demolish due to their high environmental impact, and the costs for demolition and waste disposal are also high. The overlay method, which generates almost no waste, is ideal for such roofs.
Some of you may be wondering, “Is it safe to live in a building that uses asbestos-containing materials?” but rest assured. As long as there is no destruction or crushing, it will not disperse into the air.
If you are unsure about the type of roof on your home, please feel free to consult us.
Additionally, we can complete the work in a shorter timeframe than painting or re-roofing. A shorter construction period means lower labor costs, which in turn makes the expenses more affordable.
The psychological anxiety of having to live in an environment that is different from usual is also reduced.
When scaffolding is set up, there may be inconveniences such as difficulty in entering and exiting or being unable to open windows. Being able to return to normal life in a short period is certainly a significant advantage.
Our company specializes in roofing work, but roof overlay (cover method) projects are the most frequently executed jobs we handle. We are very grateful that we are continuously able to carry out roof overlay (cover method) projects without interruption.
