Miyamae Ward Roof Overlay Construction Photos

1. Existing Roof Ridge Demolition

We will demolish the unnecessary existing ridge flashing for the overlay method!

2. Roofing Installation (Waterproof Sheet)

Next, we will install the roofing sheet (waterproof sheet)!

The roofing used is Tajima Roofing / Tadi Self!
It is a delayed adhesive modified asphalt roofing material, which is said to have double the durability compared to regular asphalt roofing.
Due to its adhesive properties, it sticks to the substrate, providing higher waterproofing than standard roofing.
As a primary waterproofing measure, if the roofing is solid, there will be no leaks!
We will ensure it is securely adhered to prevent it from blowing away.

3. Component Processing (Kera and Karakusa)

Before the main roof construction, we will process and install components such as kera and karakusa flashing!
The materials used for the components are galvalume steel sheets.

4. Main Construction – Asahi Fiberglass / Ridgeway

After processing the ridgeway components, we will install the main body up to the wall edge! We will apply single cement while working on the overlapping areas.
Once the installation is complete, we will set up the necessary materials for fixing the ridge board, known as the kanban. There are two types of kanban: cedar and resin, and this time we used the resin type!
The resin type is expected to have three times the durability compared to the cedar type!

6. Processing of Ridge Board and Sealing at Various Locations

We will process and install the ridge board. We will firmly apply sealing on the inside of the joints.
The nails and screws used for fixing are made of stainless steel, which is resistant to rust!

About the Roofing Material

The roofing material used is the Ridgeway from Asahi Fiberglass.
Ridgeway comes with a 10-year manufacturer warranty.
Since it uses natural stone that is baked and painted on the surface, it is a roofing material that does not require painting, thus reducing maintenance costs!
Additionally, because it uses fine natural stones on the surface, you won’t be troubled by rain noise.
Moreover, it is a lightweight roofing material, making it strong against earthquakes and providing seismic resistance.

*After installation, the surface decorative stones may fall off for about a week, but there is no problem with the quality.

What is the Roof Overlay (Cover Method)?

The roof overlay method involves leaving the current roof almost intact 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 its most significant feature, leading to various advantages.

The only parts that require demolition and waste disposal are the ridge caps, making it more cost-effective compared to complete roof replacement.
In 2004, regulations regarding the concentration of asbestos in raw materials were changed (for more details, please refer to the Ministry of Health, Labour and Welfare’s website).
Some building materials used in structures built before 2004 contain asbestos. Asbestos-containing materials are challenging 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 may wonder, “Is it safe to live in a building that uses asbestos-containing materials?” 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 consult us.

Additionally, the construction can be completed in a shorter time frame compared to painting or complete roof replacement. A shorter construction period means lower labor costs, which in turn makes the overall cost more affordable.
The psychological anxiety of having to live in an unusual environment is also reduced.
When scaffolding is set up, there may be inconveniences such as difficulty entering and exiting or not being able to open windows. Being able to return to normal life in a short period is a significant advantage.

Our company specializes in roofing work, and the roof overlay method is the most frequently performed type of work we undertake. We are very grateful that we continuously have projects for the roof overlay method without interruption.
