About 1 week
We received an inquiry from a customer living in Higashiyamato City, Tokyo, stating, “The roof is severely deteriorated, so I would like to request a quote for lightweight and highly durable roofing materials!”
Our Proposal
Since the customer requested lightweight and highly durable roofing materials, we proposed the lightweight and highly durable Super Galtect! The customer chose Super Galtect Fluorine, which has a 5-year longer coating warranty than Galtect, making it a highly durable roofing material.
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, make sure to check for warranties.
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 offers a warranty period, repairs may be done for free within that period.
Warranty periods vary by contractor and type of work, but typically range 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 both roof overlay work 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 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 obtain estimates from multiple contractors.
Even for the same repair, the costs may vary between contractors, and the warranties and after-services may differ as well.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired repair contractor at a lower price, it is essential to obtain estimates from multiple companies.
If a leak occurs, you may feel rushed, but
first perform temporary measures, and if construction is needed, calmly consider your options to ensure the work is satisfactory!
Kakeru Koumuten is happy to assist with emergency leak repairs as well!
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 determine 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 unnecessary leak repairs being suggested.
Moreover, having to investigate and then request a subcontractor will incur additional time and costs.
By having the knowledge and experience to perform the work in-house, responsible and cost-effective leak repairs can be carried out quickly.
