Roof Replacement Construction Procedure

1. Dismantling of Existing Roof Ridge Flashing

We will dismantle the existing roofing materials (ridge cap, snow guards) that are unnecessary for the

roof overlay method! The existing wooden purlins in the photo are made of wood. The lifespan of wooden purlins is about 10 to 15 years. Exceeding the lifespan can lead to corrosion and discoloration, resulting in the ridge cap coming loose or being blown away.

2. Roofing Installation (Waterproof Sheet)

The roofing used for

3. Custom Fabrication (Curlicue, Eaves, Valley)

4. Main Construction (Asahi Fiberglass/Ridgeway)

5. Ridge Cap, Rain Guard Metalwork Processing, and Sealing at Various Locations

6. Cleaning

We will clean up the debris that has fallen onto the balcony and rain gutters. We will conduct a thorough cleaning to prevent injuries from nails and metal scraps.

About the Roofing Material

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

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 on top, 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 part that requires demolition and waste disposal is the ridge cap, making it more cost-effective compared to re-roofing.
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 website).
Building materials used in structures constructed 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 may wonder, “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 time frame than painting or roof replacement. A short construction period means lower labor costs, which in turn makes the expenses 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 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, and the roof overlay (cover method) is the most frequently performed type of work we undertake. We are very grateful that we are continuously able to carry out roof overlay (cover method) projects without interruption.
