The pitch is the angle of fall made by the front bar of an awning. The pitch determines how much water may puddle on the awning when the awning is fully extended.
The less pitch an awning has, the more impact rain will have on the awning. All awnings will eventually fail if too much water or weight is allowed to collect on them. When set at the minimum pitch, an awning may collect rain even when the fabric is tight.
The more pitch you have, the less you will have to worry about rain collecting on the awning. Increasing the pitch, even a few inches, will have a dramatic reduction on the awning’s ability to collect rainwater. The pitch of an awning is not a factor if the awning is retracted during rain events. It’s always best to retract the awning when not in use no matter what the weather forecast.
Adjusting the pitch can also provide better shade depending on the angle of the sun in relation to the angle of the awning.
