| Inquiry Details |
| We received an inquiry from a customer living in Sumida-ku, Tokyo, stating, “Since the building is quite old, I would like to request an estimate for the roof overlay method!” |
Our Proposal
The existing roofing material is slate, which contains asbestos.
Replacing asbestos-containing roofing materials can be very costly, so the roof overlay method is recommended.
It is important to check the strength of the underlying structure; if it is soft or weakened, a complete replacement or additional sheathing before the overlay work will be necessary.
Since there were no issues with the strength of the underlying structure this time, we prepared an estimate for the roof overlay method as per the customer’s request.
The customer expressed a preference for lightweight and highly insulated roofing materials, so we proposed Super Galtect.
As the customer indicated that “a lifespan of about 20 years for the roof would be sufficient,” we suggested using materials with an approximate durability of 20 years for the ridge structure and roofing sheet to keep costs down.
Normally, we recommend that both the ridge structure and roofing sheet match the main 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.
For this reason, if you choose a contractor that offers 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 warranties andafter-service options.
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 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 work, the costs can vary between contractors, as well as the warranties and after-service options.
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 several contractors.
If a leak occurs, it’s natural to feel anxious, but
first, perform only emergency measures, and if you decide to proceed with construction, 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 may lack the necessary knowledge and experience, leading to suggestions for repairs in the wrong areas or ineffective leak repairs.
Moreover, relying on subcontractors after an investigation incurs additional time and costs.
By having the knowledge and experience to perform the work in-house, we can provide prompt and cost-effective leak repairs with accountability.
