The ridge flashing is to be used on apex buildings to cover the void where the sheets meet at the ridge of the building. These ridges are in a plain galvanised finish in a 0.7mm gauge. These used to be used with old asbestos roofs but are now more commonly used with 3" galvanised corrugated sheeting.

How much should I lap the ridges over one another?
You should have a minimum of 150mm for lapping the ridges.
Do I just fix it down with the top run of main fixings?
No, you want to use the stitchers screws to stitch the ridge to the highest point of the profile on the sheet.
How do I know what angle ridge cap I need?
To work out the ridge angle, you will need to work out the angle of each slope (commonly the same each side on apex buildings). You then minus the two angles from 180° degrees to give you the angle of ridge you need. E.g. if you have an equal apex roof with 30° it would be 180° - (30° + 30°) = 120°.
Is there any flexibility in the ridge flashing?
There is a small amount of flexibility in the ridge, so if you are using our 120° stock ridge you will be able to flex it some degrees either way.
Can I get different sized flashings?
Yes, we can manufacture made to order flashings. If you want to make an enquiry, please contact our sales team.
Can Southern Sheeting cut flashings?
Southern Sheeting will not cut stock flashings. Made to order flashings can be cut to different lengths and girths.
