Hello!
I am Yamanaka from Kakeru Koumuten Co., Ltd., a specialist in roofing, exterior painting, and exterior renovations located in Aoba-ku, Yokohama, Kanagawa Prefecture!
This is a case study of a roof renovation in Machida City, Tokyo.
The work involved a roof overlay (cover method) (Ridgeway)!
We implemented measures against leaks through the roof work!
The existing roofing material is Kubota’s (now Keimyuu) Colonial Neo, which is well-known as a roofing material that cannot be painted.
This roof had approximately 30 cracks…
Thank you very much for choosing Kakeru Koumuten Co., Ltd. from among many contractors.
Roof Overlay Construction Procedure
1. Demolition of Existing Ridge and Snow Stops
We will dismantle only the ridge cap and snow guards that may obstruct the roof overlay work.
2. Roofing Installation (Waterproof Sheet)
The roofing used this time is modified asphalt. It offers double the durability of standard asphalt roofing!
3. Fabrication of Accessories (Karakusa, Keraba, Valley)
We will process and install the keraba and karakusa.
4. Skylight Metalwork
Once the main body is covered up to the skylight, we will proceed with the metalwork for the skylight.
We will process the metal to ensure that rainwater is properly drained off the main body.
5. Main Body Construction
After installing the main body, we will set up the ridge and wall plates. This time, we used cedar plates, but there are also resin plates that are resistant to corrosion.
6. Ridge Metal Processing
We will process and install the ridge metal. We will firmly apply sealing on the inside of the joints.
7. Cleaning
We will remove and clean up any debris that has fallen around the ridge metal, the house, and inside the rain gutters.
We strive to ensure that the area looks cleaner after the work than before!
With that, the construction is complete!
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 onto 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.
Colors
■ Dual Black
■ Harvard Slate
■ Vintage Green
■ Dual Brown
This time, the roofing work with dual brown turned out exceptionally well!
The customer was very satisfied, and I was also very happy!
Thank you very much!
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 layered, it is also referred to as “overlapping roofing.”
Benefits of the Overlay Method
Since a “new roof” is placed over the “current roof,” demolition work is almost unnecessary, meaning that very little waste material is generated.
This is the biggest feature and leads to various benefits.
The only part that requires demolition and waste disposal is the ridge cap, so compared to complete roof replacement, the cost is lower.
In 2004, regulations regarding the concentration of asbestos in raw materials were changed (for more details, please visit the Ministry of Health, Labour and Welfare website).
Some building materials used in structures constructed before 2004 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 with us.
Additionally, the construction can be completed in a shorter period than painting or complete roof replacement. A shorter construction period means lower labor costs, which in turn makes the costs lower.
The psychological anxiety of having to live in a different 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 are continuously able to carry out roof overlay projects without interruption.
