| We received an inquiry from a customer living in Kodaira City, Tokyo, stating, “The roof is deteriorating significantly, and I think it’s time to seriously consider roof work. I am requesting estimates from several contractors. I believe painting will be difficult, so I would like to request an estimate using lightweight and highly durable roofing materials.” |
Our Proposal
Since the customer wanted roofing materials that would last as long as possible, we proposed the roof overlay method using the highly durable Super Galtect.
Check for Warranty and After-Service
When choosing a leak repair contractor, let’s confirm the warranty availability.
Leak repairs can recur even after a repair is done, so if you request repairs every time a leak reoccurs, it can lead to significant expenses.
For this reason, if the contractor has 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 measures or partial repairs often do not come with a leak warranty.
Additionally, some contractors offer after-service separate from the warranty, so be sure to check if the contractor you are considering has warranty andafter-service.
Kakeru Koumuten Co., Ltd. provides a leak warranty for roof overlay (cover method) and roof replacement work.
Similarly, for exterior walls, there is always a leak warranty for exterior wall cover work, replacement work, and joint sealing work.
As part of our aftercare, we send out DM every year, allowing for annual 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, 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 preferred repair contractor at a lower price, it is essential to obtain estimates from several companies.
If a leak occurs, it’s natural to feel anxious, 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, pinpointing the cause may take time and requires 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 ineffective leak repairs.
Moreover, having to investigate and then request a subcontractor adds unnecessary time and costs.
By having the knowledge and experience to perform the work in-house, we can provide prompt and cost-effective responsible leak repairs.
