Hi, Maybe you can help me find answers to why my ceiling issues. I hear a small crackling and snapping sound in my ceiling. It is a newly renovated house with ceiling panels made out of metal furring and thin marine plywood. I hear these sounds at any time of the day. When I examine the ceiling, I do not see anything unusual events except that sometimes at mid afternoon I hear my metal sheet roof snapping but hat is very light and faint. I read in other sites that are "western setting" that it could be the metal furring expanding and contracting due to heat but then I do not know of Philippine setting. Please help. Thanks
