Additionally, since the customer requested a cost-effective roofing material, we suggested using Ridgeway asphalt shingles for this project.
Check for Warranty and Aftercare Services
When choosing a leak repair contractor, make sure to check for warranty availability.
Water leak repairs can recur even after a repair has been made, so if you request repairs every time a leak reoccurs, it can lead to significant expenses.
For this reason, if you choose a contractor that offers a warranty period, you may be able to have repairs done for free within that warranty period.
The warranty period varies depending on the contractor and the type of work, but it is typically set between 1 to 10 years.
Emergency measures or partial repairs often cannot come with a water 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 and after-sales services available.
Kakeru Koumuten Co., Ltd. always includes a water leak warranty with roof overlay work and roof replacement work.
Similarly, for exterior walls, a water leak warranty is always included with exterior wall overlay work, replacement work, and joint sealing work.
We also send out annual direct mail for aftercare maintenance, making aftercare maintenance possible every year.
Obtain estimates from multiple contractors (at least 3 companies)
When requesting roof renovations or water leak repairs, be sure to get estimates from multiple contractors.
Even for the same repair, the 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 secure the best price, it is essential to get estimates from several contractors.
Therefore, while it’s natural to feel rushed when a water leak occurs, it’s best to first perform emergency measures and calmly consider the details of the work to ensure you won’t have regrets!
Kakeru Koumuten Co., Ltd. is happy to assist with emergency measures for water leaks!
Confirm whether they conduct water leak investigations and roof repairs in-house
Water leaks can sometimes be quickly identified, while in other cases, it may take time to pinpoint the cause, requiring knowledge and experience.
Contractors that completely outsource roof repairs and water leak repairs to subcontractors may lack the necessary knowledge and experience, leading to inappropriate or unnecessary repair suggestions.
Moreover, having to investigate and then request a subcontractor can incur additional time and costs.
By handling everything in-house, a contractor can leverage their knowledge and experience to provide prompt and cost-effective responsible water leak repairs.
Kakeru Koumuten Co., Ltd. conducts everything from investigating leaks to actual construction in-house!
