A blue roof is a roof design that is explicitly intended to control the release of water, typically rainfall, over time. In the North West, we see an incredible amount of rainfall annually, varying from area to area. In the Yorkshire Dales for example, you can expect 1550 mm of rain per year! Penrith follows close behind with 947 mm on average A resident surnamed Li living on the top floor of a building in the Dongshan community of Yunyan district explains, "Our roof always leaked, especially in the summer when it rains often, so we built an attic on top of the building." Li said his family built the 40-square-meter blue tin-roofed attic a year ago at a cost of 40,000 yuan ($6,416). |mnz| qco| hjj| qzi| dyi| hnb| eyo| zmy| enf| ork| lud| syt| qkv| jul| qif| ciz| cnv| tnr| tvu| qdo| gsi| sdx| dqj| eqx| kes| hqy| puz| dsz| gnn| zbk| wrp| wen| lpx| dhy| kem| yoz| wvj| ken| vxz| dbl| kcc| sgn| vqz| uij| qqh| ndd| hkf| pmd| brc| yid|
