Repair details,the process leading to the repair,materials used,repair costs,repair duration, etc.

Our Proposal
The existing roofing material is a slate roof containing asbestos and has never been painted.
After checking the condition of the substrate, we found it to be strong, so we proposed three recommended roofing materials that align with the customer’s requests!
In roofing work, not only the roofing materials but also the roofing sheet and ridge base are important, and we provided thorough explanations and proposals regarding these!
The customer obtained estimates from four companies and entrusted the work to us with our Diplomat Star plan!
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, let’s confirm the warranty availability.
Since leak repairs can recur even after one repair, requesting repairs every time a leak reoccurs can lead to significant expenses.
For this reason, if you choose a contractor that offers a warranty period, you may be able to get repairs 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-sales service separate from the warranty, so be sure to check if the contractor you are considering has warranties andafter-sales services.
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 and replacement work as well as 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 work, the costs can vary between contractors, as well as the warranties and after-sales services offered.
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 multiple contractors.
If a leak occurs, it’s natural to feel rushed, but
first perform emergency measures, and if you decide to proceed with repairs, taking your time to consider will help ensure you don’t have regrets about the work!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency leak measures as well!
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 of the leak, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs to subcontractors often lack the necessary knowledge and experience, which may lead to repairs being suggested for the wrong areas or unnecessary leak repairs.
Moreover, having to investigate and then request a subcontractor adds extra 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.
Kakeru Koumuten Co., Ltd. conducts everything from leak investigations to construction in-house!
