Kakeru Koumuten Co., Ltd.’s roof repair case studies in Aso-ku, Kawasaki
We received an inquiry from a customer living in Asao-ku, Kawasaki, stating, “The roofing material has fallen due to strong winds, so I would like you to take a look!”
Our Proposal
The existing roofing materials have many cracks and some are on the verge of falling off, with numerous repair marks from previous painting.
The existing roofing material is “Resasu,” which is very brittle and cannot be painted.
The only effective roof repair methods are the roof overlay (cover method) or complete replacement.
In the case of the roof overlay, it is necessary to use a roofing sheet specifically designed for covering fragile slate.
There are many solar panels installed, and to perform the roof overlay, they need to be removed and reattached.
Depending on the roofing material, it may be possible to reuse the existing solar panel mounting brackets, but this time the customer requested the roof overlay using the highly durable and insulated Super Galtect, so it will be necessary to change to mounting brackets compatible with Super Galtect.
We proposed the roof overlay using the Super Galtect that the customer desired, along with the removal and reattachment of the solar panels, and they entrusted us with the work!
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, let’s confirm the warranty status.
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 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-sales services separate from warranties, so be sure to check if the contractor you are considering has warranties andafter-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 for exterior wall overlay and replacement work, as well as for joint sealing work.
As part of our aftercare, we send out annual direct mail, 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, costs may vary between contractors, and 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 cost, obtaining estimates from multiple contractors is essential.
If a leak occurs, it’s natural to feel anxious, but
first, perform temporary measures, and when considering construction, taking your time to think it through will lead to a satisfactory outcome!
Kakeru Koumuten is happy to assist with emergency leak measures as well!
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 can be quite challenging, requiring 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 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 perform the work in-house, we can provide prompt and cost-effective responsible leak repairs.
