Is an overhanging roof shelter enough to safely leave bike outside? So I’ve built a shelter to keep the rain off my bike and intend to  keep it outside most of the year. It’s just a sloping corrugated plastic roof to keep the rain off it.
Will this be enough do you think? I could also put a tarp over but wonder if it’s better having the air and just being protected by the rain. Not sure if the condensation will do damage if I leave it uncovered.
A roof is better than no roof, but not as good as an enclosed space because wind can blow through bring dust and dirt and moisture.
Sunlight is also a source of slow continuous damage.  For years I kept bikes under a carport that was also sheltered from the sun, and while they still rusted, it was much slower than if they were out in the weather.
If safety means secure-from-theft then a roof makes practically no difference.  If someone wants to steal it they will.
Airflow can be useful, but a closed dry space is good too.  You want to avoid a damp airless space because that's not good.
