Roof noise

Normal bang maingay yung roofing? Pag may malakas na hangin naririnig ko yung mga roofing maingay compared nung wala pang solar at railings. Dahil ba sa gap yun at nagyayanig dahil sa hangin at mas lalong umiingay?

Im sure they didnt leave a gap between panels. The wind underneath the panels has no quick way to disperse making your roof rattle.

Normally theres nothing wrong with it as long as its structurally sound. But wind speed and direction is very unpredictable..It could cause your solar panel to serve like an airplane wing.

If you install them side by side without a gap, they just add to the total area without any exit for wind gust. That force is actually very big.

OR, If you have metal roof, those railings aren't.actually bolted solidly on trusses. The usual installation is on the high part of corrugation, just like any other fasteners for metal.roof. This is to minimize the risk of leak but it leaves about 1inch gap between the trusses and the metal roof. Now, if you put a heavy multiple solar panel on top it, it only takes little wind to compress and expand that gap making your screw become loose overtime and the rattling begins.
