Upstand flashing - 45 degree roof - 230mm

Upstand flashing are rigid metal flashings that fit over the flue pipe where it extends out of your roof.
These are approximately 10mm larger than your flue pipe and is ordered according to your roof pitch.
An upstand flashing requires a storm collar which will be fitted over the upstand to seal around the opening making your roof flashing waterproof.
Upstands should be fitted with soaker sheets that extend up to your roof apex. Soaker sheets are fitted under the apex roof cap. This means that any water runs over the soaker sheets and upstands. Upstands and soaker sheets are fixed to your roof with tek screws.
