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

Examples of leak repairs by Kakeru Koumuten Co., Ltd. in Suginami-ku
Our Proposal
This time, since the existing roof is a slate roof, we proposed the roof overlay (cover method). The roofing material used is the insulated roofing material, Danetsu Top.
Additionally, Danetsu Top is lightweight and resistant to earthquakes, making it a roofing material that is strong against earthquakes due to its overwhelming lightness and sturdy fastening.
Check for Warranty and Aftercare Services
When choosing a rain leak repair contractor, make sure to check for warranty availability.
Since rain leak repairs can recur even after one repair, requesting repairs every time a leak reoccurs 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 the nature of the work, but it is generally set between 1 to 10 years.
Emergency repairs or partial fixes often do not come with a rain leak warranty.
Additionally, some contractors offer after-sales service separate from warranties, so be sure to check if the contractor you are considering haswarranties and after-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 obtain estimates from multiple contractors.
Even for the same repair work, the costs may 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, obtaining estimates from multiple contractors is essential.
If a leak occurs, it’s natural to feel anxious, but
first, perform temporary measures, and if construction is needed, taking your time to consider will lead to a satisfactory outcome!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency leak measures as well!
Confirm whether 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 challenging, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs may lack the necessary knowledge and experience, leading to repairs in the wrong areas or suggesting unnecessary leak repairs.
Moreover, having to investigate and then request subcontractors can incur additional 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!
