| Inquiry Details |
| We received an inquiry from a customer living in Kawasaki-ku, Kawasaki: “I am considering a renovation of the roof where solar panels are installed. I think it will be necessary to detach and reattach the solar panels, so I would like a plan that uses highly durable roofing materials to minimize the need for future renovations. Since scaffolding will be set up, I would also like an estimate for exterior wall painting.”! |
Our Proposal
Regarding the roof, since the underlying structure was solid, we proposed the roof overlay method!
We created estimates for four types of roofing materials and explained the advantages and disadvantages of each.
As you requested highly durable roofing materials, we entrusted the roof overlay method using the highly durable Diplomat Star!
For the detachment and reattachment of the solar panels, we will replace the existing base rack with aluminum catch-type fittings, as it is difficult to use the existing one.
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, let’s confirm the availability of a warranty.
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.
Therefore, if the contractor has a warranty period, repairs may be done for free within that warranty period.
The warranty period varies depending on the contractor and the 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-service separate from the warranty, so it’s important to check if the contractor you are considering has a warranty andafter-service available.
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 work, replacement work, and joint sealing work.
As part of our after-maintenance, 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 get estimates from multiple contractors.
Even for the same repair, costs and warranties or after-services may vary between contractors.
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 only emergency measures, and if you decide to proceed with repairs, taking your time to consider will lead to a satisfactory outcome!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency leak repairs!
Check if the company conducts leak investigations and roof repairs in-house
Leaks can sometimes be easily identified, while in other cases, it may take time to pinpoint the cause, requiring knowledge and experience.
Contractors that completely outsource roof repairs and leak repairs to subcontractors 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 adds extra 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.
Kakeru Koumuten Co., Ltd. conducts everything from leak investigations to construction in-house!
