Sheetmetal covered roof planks having waterproof joints |
摘要 |
Common tongue and groove roof decking planks are covered with sheetmetal to make the planks themselves weatherproof. The sheetmetal is formed so that the individual planks can be interlocked together with a weatherproof joint which also hides from view and the weather the nails used to spike the roof planking down to the roof framing.
