Kakeru Koumuten Co., Ltd.’s roof repair case studies in Kamakura City


Our Proposal
The existing roofing material is slate containing asbestos, and the disposal cost for asbestos-containing roofing materials is high, making a complete replacement quite expensive. Therefore, since the underlying structure was solid, we proposed the roof overlay (cover method).
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, be 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 you choose a contractor that offers a warranty period, repairs may be done for free within that warranty period.
The warranty period varies by contractor and the nature of the 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-sales services separate from warranties, so be sure to check if the contractor you are considering has warranties andafter-sales services.
Kakeru Koumuten Co., Ltd. provides a leak warranty for both roof overlay and roof replacement work.
Similarly, for exterior walls, a leak warranty is included for exterior wall overlay and replacement work as well as 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)
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.
Furthermore, 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 anxious, but
first, perform temporary measures, and when considering construction, taking your time to think it through will lead to a satisfactory outcome!
Kakeru Koumuten Co., Ltd. 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, the source of the leak may be difficult to pinpoint, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs may lack the necessary knowledge and experience, leading to repairs of incorrect areas or proposals for ineffective leak repairs.
Additionally, having to investigate and then request a subcontractor can incur extra 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!
