Flow of leak cause investigation
Leaks are not always caused directly above the water stains. Rainwater that enters from the roof or exterior walls often travels through the waterproof sheet or inside the walls and emerges at a distant location. If we only seal the surface without identifying the cause, there is a possibility of recurrence, so Kakeru Koumuten conducts investigations in the following manner.
- Indoor Inspection: Check for water stains, conditions in the attic, and inside the walls to understand where the rainwater is coming from.
- Roof Inspection: Inspect for cracks or misalignment in the roofing materials, lifting or pulled nails in the ridge flashing, valley flashing, and around skylights.
- Exterior Wall and Balcony Inspection: Check for cracks in the exterior walls, sealing around joints and sashes, coping, and the waterproof layer and drainage of the balcony.
- Drone and Thermography: If unable to access the roof, use a drone for photography and, if necessary, check for moisture spread inside the walls and attic with a thermographic camera.
- Report with Photos: We will explain the cause and necessary repair scope with a report that includes photos and provide you with an estimate.
Inspections and estimates are free. We also accept requests for emergency repairs only.

Guidelines for Repair Scope Based on Inspection Results
| Inspection Results | Main Actions |
|---|---|
| Cracks or misalignment in 1 to several roofing materials | Replacement of roofing materials or partial repairs |
| Lifting or pulled nails in the ridge flashing, substrate corrosion | Replacement of ridge flashing and counter battens |
| Water infiltration from exterior wall joints or around sashes | Sealing and repairs of junctions |
| Localized issues around coping or skylights | Partial repairs of flashing and waterproofing |
| Deterioration of the balcony waterproof layer | Waterproofing work and renovation drains, etc. |
| Overall roof deterioration, lifespan of waterproof sheets | Roof overlay (cover method) or re-roofing |
| Substrate corrosion and multiple leak points | Re-roofing work including substrate repairs |
※ The official method will be determined based on the results of the on-site inspection. Please refer to the above as a guideline.
Concept for Preventing Recurrence
To address rain leaks, it is necessary to repair both the “entry points for rainwater” and the “pathway to the interior.” Even if only the entry point is sealed, there may be leaks to other areas due to deterioration remaining in the waterproof sheets or substrate. At Kakeru Koumuten, we not only repair the entry points but also check the condition of the waterproof sheets and substrate along the pathway, including necessary repair areas in our proposals. Depending on the construction content, we conduct water tests and checks after rainfall, and inspect for recurrence during aftercare maintenance.
How to Choose a Rain Leak Repair Contractor
In Edogawa-ku, there are many water leak repair contractors, and you may be unsure which one to choose.
For this reason, when requesting roof repairs or water leak repairs, let’s check the following 4 points.
● Have extensive experience in roof repairs and water leak repairs
● Confirm the presence of warranties and aftercare services
● Obtain estimates from multiple contractors (at least 3 companies)
● Check if they conduct water leak investigations and roof repairs in-house
By confirming the above 4 points, you will be able to choose a reliable contractor.
Have extensive experience in roof repairs and water leak repairs
Roof repair contractors often have websites that showcase their construction achievements.
These achievements may include the following items, so check if they have performed repairs similar to your home.
Repair details,the history leading up to the repair,materials used,repair costs,repair duration, etc.
Additionally, if they provide detailed explanations of the repair contents with photos, it can give you peace of mind as a reference when you actually request repairs.
If you are concerned about whether the contractor you are about to request will respond properly, choose a contractor with extensive repair experience.
Kakeru Koumuten specializes in roof and exterior repairs, and we receive many requests for water leak repairs.
Kakeru Koumuten’s Roof Replacement Case in Edogawa-ku
| Construction Location |
| Edogawa-ku, Tokyo |
| Construction Details |
| Temporary Scaffolding Installation Roof Replacement Work |
| Existing Base/Materials Used |
| Existing Roofing Material: Monier Tiles New Roofing Material: Super Galtect |
| Price Range |
| 800,000 yen – 900,000 yen |
| Completion Month |
| May 2023 |
Our Proposal
Monier tiles are difficult to paint due to the deterioration of the surface slurry layer, and because they are heavy, a roof overlay (cover method) cannot be applied while leaving the existing tiles. Given that the tiles were nearly 30 years old and had also deteriorated, we removed the tiles, installed a new waterproof sheet, and replaced them with lightweight Super Galtect to prevent leaks and reduce the weight of the roof.
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, contractors that offer a warranty may provide free repairs within the warranty period.
The warranty period and the symptoms covered vary depending on the type of work done.
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 leak warranties tailored to the scope of work for roof overlay and roof replacement projects.
Similarly, for exterior walls, we offer warranties for exterior wall overlay and replacement work as well as 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)
When requesting roof renovations or leak repairs, be sure to obtain estimates from multiple contractors.
Even for the same repair, costs can vary between contractors, as well as warranties and aftercare services.
Additionally, obtaining multiple estimates makes it easier to negotiate prices.
To request your desired contractor at a lower price, obtaining estimates from several contractors is essential.
If a leak occurs, it’s natural to feel rushed, but
first perform emergency measures, and if construction is needed, taking your time to consider will lead to a satisfactory outcome!
Kakeru Koumuten is happy to assist with emergency leak measures only!

Check if the Company Conducts Leak Investigations and Roof Repairs In-House
There are cases where the source of a leak can be quickly identified and cases where it is difficult to pinpoint the cause of the leak, requiring knowledge and experience for accurate identification.
If a contractor completely outsources roof repairs and leak repairs to subcontractors, they may lack the necessary knowledge and experience, leading to repairs in the wrong areas or suggestions for ineffective leak repairs.
Additionally, having to investigate and then request a subcontractor adds extra time and cost.
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!
