Inquiry Details

We received the following inquiry from a resident of Kohoku-ku, Yokohama. “I am considering the roof overlay (cover method) and exterior painting for my 19-year-old house. I have already received estimates from several companies. I would like to request an estimate using Super Galtect, which has excellent insulation and wind resistance. I think 20 years of durability is sufficient, so I would like to lower costs by using lower-grade roofing sheets and purlins. Regarding the exterior painting, since the existing surface is painted, I hope to maintain its aesthetic appeal.”

Check for Warranty and Aftercare Services

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 the type of work, but it typically ranges from 1 to 10 years.
Emergency repairs or partial fixes often do not come with a leak warranty.

Additionally, some contractors offer aftercare services separate from warranties, so it’s important to check if the contractor you are considering has warranties andaftercare services.

Kakeru Koumuten Co., Ltd. provides a leak warranty for all roof overlay and roof replacement work.
Similarly, exterior wall cover work and replacement work, as well as joint sealing work, also come with a leak warranty.
As part of our aftercare, we send out annual newsletters, and inspections can be arranged upon request.

Obtain Estimates from Multiple Contractors (at least 3)

When requesting roof renovations or leak repairs, be sure to get estimates from multiple contractors.

Even for the same repair, costs and warranties or aftercare services can vary between contractors.

Additionally, obtaining multiple estimates makes it easier to negotiate prices.

To request your desired repair contractor at the best possible price, obtaining estimates from multiple contractors is essential.

If a leak occurs, it’s natural to feel rushed, but
first perform only emergency measures, and if you decide to proceed with repairs, taking your time to consider will help ensure you won’t regret your choice!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency leak repairs only!

Confirm if the Company Conducts Leak Investigations and Roof Repairs

There are cases where the source of a leak can be quickly identified, and cases where it is difficult to pinpoint the cause of the leak, requiring knowledge and experience for accurate identification.
If a contractor completely outsources roof repairs and leak repairs to subcontractors, they may lack the necessary knowledge and experience, leading to repairs being suggested for areas unrelated to the cause or unnecessary work being proposed.
Additionally, since they investigate and then request subcontractors, it results in extra time and costs.
By performing the 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!
