The construction results may explain the following items, so let’s check if similar repairs have been carried out on your home.
Repair details,the process leading to the repair,materials used,repair costs,repair duration, etc.

Kakeru Koumuten Co., Ltd.’s roof repair case studies in Zushi City
Our Proposal
Upon visiting the site, we found that the ridge cap was lifted. The internal wood of the ridge was also damaged, so we proposed to replace the wood and the ridge cap.
Additionally,
since this construction was due to wind damage, fire insurance was applicable.
We carried out the replacement work for the ridge cap and wood, and the customer was very satisfied!
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, make sure to check for warranty availability.
Leak repairs can recur even after being fixed once, so if you have to request repairs every time a leak reoccurs, it can lead to significant expenses.
For this reason, if the contractor offers a warranty period, repairs may be done for free within that warranty period.
The warranty period varies by contractor and type of work, but it is generally set between 1 to 10 years.
Emergency measures or partial repairs often do not come with a leak warranty.
Additionally, some contractors offer after-sales service separate from their warranty, so it’s important to check if the contractor you are considering has warranties andafter-sales service.
Kakeru Koumuten Co., Ltd. provides a leak warranty for both roof overlay (cover method) and roof replacement work.
Similarly, for exterior walls, a leak warranty is included for exterior wall cover work, replacement work, and joint sealing work.
As part of our aftercare, 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 can vary between contractors, as well as warranties and after-sales services.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower cost, it is essential to obtain estimates from several contractors.
If a leak occurs, it’s natural to feel anxious, but
first, perform temporary measures, and when considering repairs, taking your time will help ensure you don’t have regrets about the work!
Kakeru Koumuten is happy to assist with temporary measures for leaks!
Check if the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be easily identified, while in other cases, pinpointing the cause can be quite difficult, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs may lack the necessary knowledge and experience, leading to proposals for repairs in the wrong areas or ineffective leak repairs.
Moreover, having to investigate and then request a subcontractor can incur additional time and costs.
By having the knowledge and experience to conduct the work in-house, we can provide prompt and cost-effective responsible leak repairs.
