Service Mast Roof Flashing - 2-1/2 in Trade Size - Galvanized Steel - Neoprene Seal - RF2-1/2
Roof flashing for a 2-1/2 in trade size service mast, used to help seal roof penetrations against water entry. Based on comparable manufacturer listings, this style is typically galvanized steel with an elastomer or neoprene-style seal for service entrance mast installations.
What this product is for
This roof flashing is used where a service mast or similar electrical mast passes through the roof. It helps shed water away from the roof opening and supports a weather-resistant seal around the mast.
Use for
Use for service entrance mast penetrations on residential and light commercial buildings, especially where a 2-1/2 in trade size mast passes through a sloped roof. Comparable products are commonly used on galvanized, plastic, or cast iron mast materials, but confirm compatibility before ordering.
Avoid for
Avoid using this item where the exact manufacturer, roof pitch range, or seal material must be confirmed for code, engineering, or replacement-match purposes. Also avoid assuming compatibility with hot-mopped or built-up roofing unless the manufacturer specifically states it.
Best for
Best for electricians and contractors replacing or installing a roof flashing on an overhead service mast where a simple, field-familiar weather seal is needed.
Installed in
Typically installed on pitched residential roofs and light commercial roof assemblies where the service mast exits above the roof line. Trade size is 2-1/2 in, approximately 63.5 mm.
Why this product exists
Roof penetrations around service masts are common leak points. A flashing with an integrated seal helps reduce water ingress around the mast and roof opening, which can help protect the building envelope and the electrical service entry area.
Compared with similar products
Compared with plain metal flashings, a flashing with an elastomer or neoprene-style seal can simplify sealing around the mast. Compared with exact manufacturer part numbers such as RF-250 or similar 2-1/2 in roof flashings, this listing remains unverified because the supplied SKU format does not match a clearly confirmed manufacturer catalogue number. Manual verification is recommended before purchase.
