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

Examples of Roof Repairs by Kakeru Koumuten in Minato-ku
Our Proposal
The existing roofing material is “Colonial NEO,” which cannot be painted. Since there are many cracks and you mentioned wanting to live here for a long time, we proposed the roof overlay method using Super Galtect.
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, make sure to check for warranties.
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, contractors that offer a warranty may provide free repairs within the warranty period.
The warranty period varies by contractor and the nature of the work, but it typically ranges from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a leak warranty.
Additionally, some contractors offer aftercare services separately 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 all roof overlay and roof replacement work.
Similarly, exterior wall overlay and replacement work, as well as joint sealing work, also come with a leak warranty.
As part of our aftercare, we send out annual direct mail, allowing for yearly inspections.
Obtain Estimates from Multiple Contractors (at least 3)
When requesting roof renovations or leak repairs, be sure to obtain estimates from multiple contractors.
Even for the same repair work, the repair costs can vary depending on the contractor, and the warranties and after-sales services may differ as well.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower price, it is essential to get estimates from multiple contractors.
If a leak occurs, it’s natural to feel anxious, but
first, perform emergency measures, and if construction is needed, taking the time to consider it calmly will lead to a satisfactory outcome!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency 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, it can be challenging to pinpoint the source. Identifying the cause requires 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 in the wrong areas or unnecessary leak repairs being suggested.
Moreover, having to investigate and then request a subcontractor incurs 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!
