Expert Verdict — Reviewed by the SuperArbor Pro Desk
The FlashVent's drop-in, fasten-and-weld sequence makes it one of the quicker vent penetrations to complete on a TPO roof. Confirm the pipe diameter matches the 4 in. boot before ordering, and weld the flange fully with a proper seam probe check per FlashCo's instructions. Pair with matching white TPO flashing membrane for a uniform penetration detail.
Heat-welding equipment poses fire and burn hazards; follow manufacturer safety instructions and roof system requirements.
Order the FlashCo 4 in. TPO FlashVent Vent Boot & Sub Base in white for fast TPO vent penetrations.
