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

| Inquiry Details |
| We received an inquiry from a customer living in Kita-ku, Tokyo, saying, “I am considering roof repair and rain gutter replacement, and I requested estimates from other companies, but I don’t know the appropriate price and would like to request a comparative estimate!” |
Our Proposal
The existing roof was a slate roof containing asbestos. Since the condition of the base was solid, we proposed a roof overlay construction.
There was a broken water heater on the roof, and we also proposed its removal and disposal!
It was said that you received estimates from four companies, but you were satisfied with both the cost and the plan, so you entrusted us with the work!
Check for Warranty and Aftercare Services
When choosing a contractor for leak repairs, make sure to check for warranties.
Leak repairs can recur even after the initial repair, so if you have to request repairs every time a leak occurs, it 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 by contractor and the 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 aftercare services separate from warranties, so be sure to check if the contractor you are considering has warranties and aftercare services.
Kakeru Koumuten Co., Ltd. provides a leak warranty for both roof overlay work 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 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 and warranties or aftercare services can differ between contractors.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower price, obtaining estimates from several contractors is essential.
If a leak occurs, it’s natural to feel rushed, but
first, perform emergency measures, and if you decide to proceed with the work, taking your time to consider will help avoid regrets!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency leak measures!
Check if the Company Conducts Leak Investigations and Roof Repairs In-House
There are cases where the source of a leak can be quickly identified and cases where it is difficult to pinpoint the cause of the leak, requiring knowledge and experience for accurate identification.
If a contractor completely outsources roof repairs and leak repairs to subcontractors, they may lack the necessary knowledge and experience, leading to suggestions for repairs in the wrong areas or unnecessary leak repairs.
Additionally, relying on subcontractors after conducting an investigation incurs extra time and costs.
By having the knowledge and experience to perform 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!
