Oak is a by-word for strength and durability but this should not be confused with the fact it is most vulnerable and can be easily degraded if constantly exposed to rain or hot sun.
A South/South Westerly elevation facing the prevailing weather is the worst scenario. To preserve the beautiful appearance and to guarantee long, trouble-free service, it is essential to provide adequate shelter from the worst elements of the weather.
