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 roof renovation and rain gutter work in Sagamihara City, Kanagawa Prefecture.
There are various types of roof renovations, and this project involves a roof overlay (cover method) for a slate roof (Ridgway)!
We implemented leak prevention measures through the roofing work!
Thank you very much for choosing Kakeru Koumuten Co., Ltd. from among many contractors.
Roof Overlay Construction Procedure
1. Existing Ridge and Snow Stop Demolition
We will dismantle only the ridge flashing and snow stops that obstruct the overlay work.
2. Roofing Installation (Waterproof Sheet)
The roofing material used this time is modified asphalt. It is expected to have double the durability of asphalt roofing!
3. Fabrication of Accessories (Karakusa, Keraba, Valley)
We will process and install the keraba, karakusa, and valley metal sheets.
4. Skylight Metal Fabrication
Once the main body is roofed up to the skylight, we will proceed with the metal fabrication for the skylight.
We will process the metal to ensure that rainwater is properly drained off the main body.
5. Main Body Construction
After roofing the main body, we will install the purlin and wall plates.
This time, we used a resin purlin that is resistant to corrosion.
6. Ridge Metal Fabrication
We will process and install the ridge metal. We will firmly apply sealing on the inside of the joints.
For the wall edges, we will use a component called rain stop metal.
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 is cleaner after the work than it was before!
This completes the construction!
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 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, we achieved an excellent finish with the Harvard slate roofing work!
Our 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.
Literally, it is a method of covering a roof with another roof. Therefore, the roof becomes double-layered. Since the roof is installed in layers, it is also referred to as “layered roofing.”
Advantages of the Overlay Method
Since a “new roof” is placed over the “current roof,” there is almost no need for demolition work, 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 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 details, please refer to the Ministry of Health, Labour and Welfare’s website).
Some building materials used in constructions completed 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 of you 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 time frame compared to 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 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 have been continuously engaged in roof overlay projects without interruption.
