Hello!
We are Kakeru Koumuten Co., Ltd., a specialist in roofing, exterior painting, and exterior renovations located in Aoba-ku, Yokohama, Kanagawa Prefecture!
This is a case study of exterior renovations in Isogo-ku, Yokohama, Kanagawa Prefecture.
The work involved repairing the roof by reapplying the foundation plaster of the ridge tiles!
We received a request from a customer for whom we previously replaced the rain gutters!
The inquiry was prompted by a passing contractor who mentioned, “The ridge tiles are misaligned.”
When we conducted a site survey, we found that the misalignment of the ridge tiles was not significant, but the foundation plaster of the ridge tiles had mostly peeled off.
If the foundation soil (Arakida) washes away, it can lead to poor balance of the ridge tiles and pose a risk of collapse, so we proposed reapplying the plaster.
On this page, we will explain the actual results of the work carried out by Kakeru Koumuten!
Thank you very much for choosing Kakeru Koumuten Co., Ltd. from among many contractors.
Repointing of Stucco
1. Preparation Work
2. Removal of Existing Stucco
Cracks and peeling are signs of deterioration! We will carefully dismantle it without disturbing the underlying soil! Depending on the type of existing stucco, we generally recommend maintenance every ten years! If the peeling stucco is left unattended, it can cause the base clay known as “Arakita”, which supports the ridge tiles, to wash away.
3. Application of New Stucco
4. Cleaning
5. Completion of Repointing
Type of plaster used

The plaster used for this project is “Nanban plaster” Silguard, black!
It contains a special waterproofing material that reduces the waterproof rate. There are two colors available, including white!
To extend the lifespan of the tiles, maintenance of the plaster is necessary.
If the plaster deteriorates, it can lead to leaks throughout the house, so if it has been over 20 years, we recommend maintenance!
We look forward to hearing from you before any leaks occur!

Summary
This concludes our record of the plaster replacement work for ridge tiles in Isohama-ku, Yokohama.
If the plaster on the ridge tiles is left unattended, it can lead to the collapse of the ridge tiles or require a “ridgetile re-stacking work,” which involves dismantling and re-stacking the ridge.
This type of work is significantly more expensive than just plaster work, so we recommend addressing any peeling plaster promptly, even if it’s just a temporary repair.
