Extensive experience in roof repairs and leak repairs

Repair details,the process leading to the repair,materials used,repair costs,repair duration, etc.

Our Proposal
The existing roofing material is a slate roof, and it is important to check the strength of the underlying structure. If the underlying structure is soft or weakened, it will require either a complete roof replacement or an overlay after reinforcing the sheathing.
This time, since there were no issues with the strength of the underlying structure, we prepared an estimate for the roof overlay method as per the customer’s request.
The customer desired lightweight and highly insulated roofing materials, so we proposed Super Galtect.
Check for Warranty and After-Service Availability
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 repairs or partial fixes often do not come with a leak warranty.
Additionally, some contractors offer after-service separately 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 also 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, 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 contractor at a lower price, it is essential to obtain estimates from several companies.
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 temporary measures for leaks!
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.
Contractors that completely outsource roof repairs and leak repairs may lack the necessary knowledge and experience, leading to suggestions for repairs in the wrong areas or unnecessary leak repairs.
Moreover, relying on subcontractors after an investigation incurs 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.
