最近、日本瓦の家が激減してる

【拡大してご覧ください。】

　家の中の空気は温まると上昇します。このため、三階の窓を開けたままにして温まった空気を外に逃がし、自然の力で換気してます。しかし、昨日はそれが裏目に出て、窓から吹き込んだ夕立ちの雨で床が大分濡れました。一杯飲んでると一人では気づき難いです。今後は気をつけます。

　ところで、三階の窓から下を見ると一階の日本瓦がきれいに見えます。最近では日本瓦の家が少ないです。築２０年ですが、雨漏りはありません。

　瓦が激減してる理由は重いからでしょう。それは昨今、頻発する地震への対策と想われます。

　
 When it gets warm, the air in the house rises. For this reason, the warm air is released to the outside through the window on the third floor open, and it is naturally ventilated. However, yesterday it was backfired, and the rain blew through the window, and the floor got wet. It's hard to notice by myself, furthermore drinking alone. I will be careful from now on.

 By the way, when I look down from the window on the 3rd floor, I can see the Japanese roof tiles on the first floor beautifully. Recently, there are few Japanese tile houses. It is 20 years old since I built, but there is no leak.

 The reason why the roof tiles are drastically reduced is probably because it is heavy. It may be due to the countermeasure against recent frequent earthquakes.
