Kakeru Koumuten Co., Ltd.’s roofing repair case studies in Tsurumi-ku, Yokohama
A customer living in Tsurumi-ku, Yokohama contacted us saying, “I want to take measures against rain leaks due to the age of the building!”
Our Proposal
Since the customer was also concerned about durability, we proposed a roof overlay (cover method) using Super Galtect, which has a long lifespan.
Check for Warranty and After-Service
When choosing a rain leak repair contractor, make sure to check for warranty availability.
Rain leak repairs can recur even after fixing, so if you have to request repairs every time a leak reoccurs, it can lead to significant expenses.
For this reason, if the contractor offers a warranty period, repairs may be done for free within that period.
The warranty period varies by contractor and type of work, but it typically ranges from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a rain 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 options.
Kakeru Koumuten Co., Ltd. provides a rain leak warranty for all roof overlay (cover method) and roof replacement work.
Similarly, for exterior walls, a rain leak warranty is included for exterior wall overlay (cover method) and replacement work, as well as for joint sealing work.
As part of our after-service, 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, 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 obtain estimates from several companies.
If a leak occurs, you may feel rushed, but
first perform temporary measures, and if construction is needed, taking your time to consider will lead to a satisfactory outcome!
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 quickly identified, while in other cases, pinpointing the cause can be challenging, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs to subcontractors 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 adds extra time and costs.
By having knowledge and experience and performing the work in-house, responsible and cost-effective leak repairs can be carried out swiftly.
