Kakeru Koumuten’sroof repair case studies in Totsuka-ku, Yokohama
A customer living in Aoba-ku, Yokohama contacted us saying, “I’m worried about the durability of the roof, so I would like you to check it once!”
Our Proposal
Since you were concerned about the durability, we specifically proposed the roof overlay method using Super Galtect, which has high durability.
Check for Warranty and After-Service
When choosing a leak repair contractor, let’s check for warranty availability.
Leak repairs can recur even after one repair, so if you request repairs every time a leak reoccurs, it can lead to significant expenses.
For this reason, if the contractor has 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-service separate from the warranty, so be sure to check if the contractor you are considering has warranty andafter-service.
Kakeru Koumuten Co., Ltd. provides a leak warranty for 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 after-service, we send out annual direct mail, allowing for inspections every year.
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, 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 cost, obtaining estimates from multiple companies is essential.
If a leak occurs, it’s natural to feel rushed, but
first, perform temporary measures, and when considering construction, taking your time will lead to a regret-free project!
Kakeru Koumuten is happy to assist with emergency leak repairs as well!
Check if the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be easily identified, while in other cases, it may take time to pinpoint the source, requiring knowledge and experience.
If a contractor completely outsources roof repairs and leak repairs to subcontractors, they may lack the necessary knowledge and experience, leading to repairs in the wrong areas or suggesting ineffective leak repairs.
Moreover, having to investigate and then request a subcontractor will incur additional time and costs.
By having the knowledge and experience to conduct the work in-house, it becomes possible to provide prompt and cost-effective responsible leak repairs.
Kakeru Koumuten conducts everything from leak investigations to construction in-house!
