How to Choose a Leak Repair Contractor
There are many leak repair contractors in Hayama, and you may be unsure which one to choose.
Therefore, when requesting roof repairs and leak repairs, let’s check the following four points.
● Have extensive experience in roof repairs and leak repairs
● Confirm the presence of warranties and aftercare services
● Obtain estimates from multiple contractors (at least three)
● Check if they conduct leak investigations and roof repairs in-house
By confirming the above four points, you will be able to choose a reliable contractor.
Extensive Experience in Roof Repairs and Leak Repairs
Roof repair contractors often have websites that showcase their construction achievements.
The construction results may explain the following items, so be sure to check if similar repairs have been performed on your home.
Repair details,the history leading to the repair,materials used,repair costs,repair duration, etc.
Additionally, having detailed explanations of the repair contents with photos can provide peace of mind as it serves as a reference when you actually request repairs.

Our Proposal
In line with the customer’s request, we proposed four types of roofing materials, including the highly durable and heat-insulating “Super Galtect” and cost-effective roofing materials for comparison!
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, make sure to check for warranty availability.
Since leaks can recur even after repairs, relying on repairs each time a leak occurs can lead to significant expenses.
Therefore, if the contractor offers a warranty period, repairs may be done for free within that warranty period.
The warranty period varies depending on the contractor and the type of work, but it is generally set between 1 to 10 years.
Emergency repairs or partial repairs often do not come with a leak warranty.
Additionally, some contractors offer after-service separate from the warranty, so it’s important to check whether the contractor you are considering has warranties and after-service.
Kakeru Koumuten Co., Ltd. provides a leak warranty for all roof overlay and roof replacement work.
Similarly, for exterior walls, a leak warranty is included for exterior wall overlay work, replacement work, and joint sealing work.
As part of our after-maintenance, we send out annual direct mail, allowing for yearly inspections.
Obtain estimates from multiple contractors (at least 3 companies)
When requesting roof renovations or leak repairs, be sure to get estimates from multiple contractors.
Even for the same repair, costs and warranties or after-services may vary between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower price, it is essential to obtain estimates from several contractors.
If a leak occurs, it’s natural to feel anxious, but
first, perform emergency measures, and if you decide to proceed with repairs, taking your time to consider will lead to a satisfactory outcome!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency leak measures!
Check if the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be quickly identified, while in other cases, it may take time to pinpoint the source, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs may lack the necessary knowledge and experience, leading to suggestions for repairs in the wrong areas or ineffective leak repairs.
Moreover, having to investigate and then outsource to subcontractors incurs additional time and costs.
By having the knowledge and experience to conduct work in-house, we can provide prompt and cost-effective responsible leak repairs.
Kakeru Koumuten Co., Ltd. handles everything from leak investigations to construction in-house!

Features of Hayama Town, Kanagawa Prefecture
Hayama Town, located in Miura District, Kanagawa Prefecture, is situated in the northwestern part of the Miura Peninsula, bordered by Zushi City to the north, Yokosuka City to the east and south, and facing Sagami Bay to the west. It covers an area of 17.04 square kilometers and is characterized by a slightly elongated terrain from east to west. The Morito River and Shimoyama River flow westward within the town, emptying into Sagami Bay. The mountains are covered with beautiful ridges and rich forests due to the Kuroshio current flowing back into Sagami Bay and annual precipitation exceeding 1,000 millimeters.
Hayama Town is a nature-rich area surrounded by the sea and mountains, with a coastline stretching 4 km north to south, featuring beautiful sandy beaches and rocky shores. On clear days, you can see Mount Fuji, Hakone, and Enoshima across the sea.
There is no railway network within the town, so the main mode of transportation is by bus. The nearest train stations are Zushi Station on the JR Yokosuka Line and Zushi-Hayama Station on the Keihin Kyuko Line, from where you can access the town by bus. It takes about 80 minutes from Tokyo Station and approximately 45 minutes from Yokohama Station. If you are driving, you can use the Zushi Interchange or Yokosuka Interchange on the Yokohama-Yokosuka Road, and visit via National Routes 16 and 134.
Hayama Town is known for the construction of the Hayama Imperial Villa in 1894, which served as a retreat for the imperial family. Due to its scenic beauty and mild climate, it is also a popular vacation spot, housing one of the three imperial villas known as “Goyotei” located nationwide.
