Door canopy / portico help, paleeese ;^)
Question:
Search endlessly for some simple palns for what I think is a doorway canopy or portico. We have standard French Doors exiting out to our deck. Its on the side of the house that gets hammered by rain. I just want to build an approximately 8 ft wide small frame and shingle roof/overhang that projects out about 4 or 5 ft. I realize I could just buy and awning but I like the idea/look of this concept better. I know i could build it myself with instructions but don’t trust myself enough to do it without guidance ;^) Will be ataching to brick on the outside. Can’t find any plans anywhere. I dont intend a full portico (slanted roof projecting out and supported by 4×4s). Just a slanted one angle mini overhang with supports that angle back toward the house at the ends and brace against the brick. Ive seen plenty of these in cape cod houses but they are typical 4 ft wide over single entry doors. Mine will be twice that. Any ideas? Thanks everyone Todd

First, the wall system that is to support the cantilevered structure consists of a 3 3/4" thick layer / curtain of brick stacked several feet high and kept in place with metal ties that connect it to the wood frame that is the structure of the building. The curtain of brick is separated from the wood structure by – say – an inch of air. Water penetrates the brick and tends to run down the cavity. This moisture is diverted back out of the cavity at the top / head of any opening in the wall with flashing. So, any structure such as the canopy in question must be supported by members that pass through the brick veneer and the cavity behind it and are attached to the wood frame. At the same time, the wood or steel members need to be protected from any moisture in the cavity; the joint between the canopy roof and the face of the brick must be closed to water; and the brick must be supported. Starting from the last, the brick removed to allow the canopy members to penetrate to the wood structure can probably be removed in small triangular sections and re laid to maintain the fabric of the veneer. Space should be left between the members and the brick to allow some movement in the canopy without stressing the veneer. Flashing can be installed to bridge the gap between canopy and veneer. The quick and easy method is to run the flashing up the face of the brick and seal the top with "stuff" which would be renewed every few years. The more permanent method is to use cap and base flashing with the base flashing running up the face of the wall and the cap flashing starting in a horizontal brick joint and dropping down over the base flashing. Protecting the members in the cavity starts with a choice between short and long term protection. In any case, materials that resist rot or rust are needed. They should be painted to resist moisture intrusion. One can stop there and let any moisture in the cavity drop past the new construction to the flashing and weep holes that already exist over the opening below. A more careful solution would be to install through wall flashing and weep holes above the new construction. TB
