It is lightweight, earthquake-resistant, and demonstrates excellent insulation performance throughout the year, achieving long maintenance due to its high durability.
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, make sure to check for warranty availability.
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, if the contractor offers 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-sales service separate from warranties, so be sure to check if the contractor you are considering has warranties andafter-sales service.
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 inspections every year.
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, 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 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 measures as well!
Check if the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be easily identified, while other times it may take longer to pinpoint the cause, 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 ineffective leak repairs.
Moreover, having to investigate and then request a subcontractor can incur additional time and costs.
By having the knowledge and experience to conduct repairs in-house, we can provide prompt and cost-effective responsible leak repairs.
