Our Proposal
This time, we proposed a roof replacement project as requested by the customer. The roofing material we suggested is the Super Galtect from Aijii Industry.
The Super Galtect used this time comes with a 15-year paint film warranty and a 25-year hole warranty from the manufacturer. Additionally, we provide a 10-year construction warranty!
Among our construction achievements, the Super Galtect from Aijii Industry is the most frequently used and has garnered significant attention!
Check for Warranties and Aftercare Services
When choosing a leak repair contractor, make sure to check for warranties.
Leak repairs can recur even after being fixed, so if you have to request repairs every time a leak reoccurs, it can lead to significant expenses.
Therefore, if you choose a contractor that offers a warranty period, you may be able to get repairs done for free within that warranty period.
The warranty period varies depending on the contractor and the type of work, but it is generally set between 1 to 10 years.
Emergency repairs or partial repairs often do not come with a leak warranty.
Additionally, some contractors offer after-service separate from the warranty, so it is important to check if the contractor you are considering has a warranty andafter-service available.
Kakeru Koumuten Co., Ltd. provides a leak warranty for 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 after-maintenance, 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 warranties and after-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 multiple contractors.
If a leak occurs, it’s natural to feel rushed, but
first perform emergency measures, and if construction is necessary, taking your time to consider will lead to a satisfactory outcome!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency leak repairs!
Confirm whether the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be quickly identified, while in other cases, it may take time 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 work in-house, we can provide prompt and cost-effective responsible leak repairs.
Kakeru Koumuten Co., Ltd. handles everything from leak investigations to construction in-house!
