【葺き替え後４年で雨漏り】葺き替えたばかりなのにどうして？（前編動画）

This video brings you a report from a roof renovation site in Sagamihara City, Kanagawa Prefecture. At this site, a slate roof was replaced with a metal roof by another company four years ago, but leaks began occurring just four years later. To address their concerns about leaks, the client subsequently contacted Teigaku, a roofing and exterior wall specialist, to perform a second roof renovation. In this video, we explain in detail why the leaks occurred so quickly, comparing differences in construction methods and fit-ups while actually removing the roof.
