Extensive Experience in Roof Repairs and Leak Repairs
Roof repair contractors often have websites that showcase their construction achievements.
The construction results may explain the following items, so check if similar repairs have been performed on your home.
Repair details,the process leading to the repair,materials used,repair costs,repair duration, etc.
Additionally, if the repair details are explained in detail with photos, it provides peace of mind as it can serve as a reference when you actually request repairs.

Our Proposal
This time, since the condition of the roof had significantly deteriorated, we proposed the roof overlay (cover method).
As the customer desired a material with high durability, we chose Super Galtect for the roofing material.
Check for Warranty and After-Service Availability
When selecting a leak repair contractor, it is important 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 repairs or partial fixes 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 options.
Kakeru Koumuten Co., Ltd. provides a leak warranty for roof overlay (cover method) and roof replacement work.
Similarly, for exterior walls, a leak warranty is included for exterior wall cover work, replacement work, and joint sealing work.
As part of our aftercare, we send out annual DM,
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, costs may vary between contractors, and warranties and after-services may differ.
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 you decide to proceed with construction, 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 in other cases, it can be difficult to pinpoint the source, 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 unnecessary leak repairs.
Moreover, having to investigate and then request a subcontractor adds extra 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.
