Extending the rafters for good soffit ventilation would be great, but would likely require reshingling the entire roof, which might be a good idea but certainly not cheap and easy with scrap materials.
The large jalousy window is nice for rain protection, but inside needs to be covered with 1/2" hardware cloth to exclude predators.
Adding more windows for light and ventilation would be good too.
Wonders if underneath the shed could be home for rodents/predators, etc?
An anti-dig apron all around the building would be good.
What kind of shape is the floor in?
@Ittybittyschmidtie maybe I missed it but....
Where in this world are you located?
Climate, and time of year, is almost always a factor.
Please add your general geographical location to your profile.
It's easy to do, and then it's always there!
