| Inquiry Details |
| We received an inquiry from a customer living in Akishima City, Tokyo, stating, “The roof is severely deteriorating, and I think it’s time to seriously consider roof work. I am requesting estimates from several contractors. I believe painting would be difficult, so I would like to request an estimate for lightweight and highly durable roofing materials.” |
Our Proposal
Since the customer wanted lightweight roofing materials that would last as long as possible, we proposed a roof overlay construction using Super Galtect, which is our most popular and highly durable option!
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, let’s confirm the 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, contractors that offer a warranty may provide free repairs within the warranty period.
The warranty period varies by contractor and the nature of the 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 be sure to check if the contractor you are considering has warranties and aftercare services.
Kakeru Koumuten Co., Ltd. provides a leak warranty for all 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 companies)
When requesting roof renovations or leak repairs, be sure to obtain estimates from multiple contractors.
Even for the same repair, the costs can vary between contractors, as well as the warranties and after-service options.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower price, obtaining estimates from multiple companies is essential.
If a leak occurs, it’s natural to feel anxious, but
first perform temporary measures, and if construction is needed, calmly consider your options to ensure you won’t have regrets!
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 be difficult to pinpoint the source, requiring knowledge and experience.
If a contractor completely outsources roof repairs and leak fixes to subcontractors, they 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 can incur additional time and costs.
By having the knowledge and experience to conduct repairs in-house, responsible and cost-effective leak repairs can be achieved quickly.
Kakeru Koumuten handles everything from leak investigations to construction in-house!
