Kakeru Koumuten Co., Ltd.’s roof repair case in Kawasaki-ku, Kawasaki City
A customer living in Kawasaki-ku, Kawasaki contacted us saying, “A piece of roofing material has fallen, so I would like you to take a look!”
Our Proposal
We proposed a roof overlay construction based on the customer’s request.
This time, the roofing material used is Ridgeway from Asahi Fiberglass.
Ridgeway comes with a 10-year manufacturer warranty.
Since it uses natural stone that is baked onto the surface, it is a roofing material that does not require painting, thus reducing maintenance costs!
Additionally, because it uses fine natural stones on the surface, you won’t be troubled by rain noise.
Moreover, being a lightweight roofing material, it is also strong against earthquakes and has good seismic resistance.
Check for Warranty and After-Maintenance Availability
When choosing a leak repair contractor, make sure to check for warranty availability.
Since leaks can recur even after a repair, requesting repairs each time a leak reoccurs can lead to significant expenses.
For this reason, contractors that offer a warranty may provide free repairs within the warranty period.
Warranty periods vary 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-sales services separate from warranties, so be sure to check if the contractor you are considering has warranties and after-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 with exterior wall overlay and replacement work as well as 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 get 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.
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 anxious, but
first perform temporary measures, and if you decide to proceed with repairs, taking your time to consider will lead to a project without regrets!
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, it may 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 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. conducts everything from leak investigations to construction in-house!
