Picture someone up a ladder with a stack of sheets and a bag of wide-headed nails. Everything the word means is in that picture: the job being done up there, and the stack of sheets waiting at the bottom. English lets the one -ing word point at either end of it, so the sentence around it decides which you are looking at.
From the word’s history
Wiktionary records roofing (noun 1) as roof + -ing, and glosses that -ing as the 'material, collection' ending rather than the action ending.
Wiktionary 把材料那個 roofing 記成 roof 加 -ing,而且特別註明這裡的 -ing 是「材料、成套」的那一種,不是動作的那一種。所以嚴格說起來,材料義不一定是從「蓋屋頂」這個動作長出來的,它可能是另一條 -ing 的路;學習上把它們看成同一個畫面的兩端仍然好用,但這是教學上的連結,不是歷史上的推導。
