This video provides information on the importance of installing flashing on wood beams to prevent water damage and extend the life of cladding. The video discusses the process of installing flashing, which acts as a barrier that redirects moisture away from building interiors and back toward the exterior of the wall. Common flashing materials include synthetic membranes and metals. To properly install flashing, it is essential to choose the appropriate material, such as lumber, flooring, or prefabricated faux beams.
To retrofit existing exterior walls, add base flashing to improve drainage, mitigate water leaks, and extend the life of cladding. Remove cladding at the base of the wall and examine exposed building wrap or felt. Polyethylene/rubber flashing panels are available for an effective, weatherproof solution.
Flashing and shielding can be done using various materials, including wood, metal, and polyethylene, to protect the wall. Extend the flashing above the beam and up the wall, and if the beam is larger than needed, rout and embed a metal flashing around door and window flanges and over roofing step flashing.
Installation steps include laying out the installation, locating studs, determining the number of mounting blocks needed, and measuring and installing the flashing.

@cattnipp I’m not real familiar with aluminum framed patios or porches. I don’t think there are a lot of building codes for these types of structures and I really don’t know of any thing that you could reference. If you have a problem with your contractor, have them come back and make the necessary adjustments. Hopefully you haven’t paid down all of their money.
thank you for this. our roofer told us we should cover our beams with copper (?) but i imagined that moisture would build up between the metal and wood and cause rot. i asked some construction workers what they were using for a similar application and they said asphalt emulsion but a company that manufactures this told me it wasn’t appropriate.
