Patio Cover Types
Patio covers provide a more permanent roofed shelter than an awning or pergola. They can be attached to the house or freestanding and can use solid panels, insulated panels or other engineered roof systems.
Pergolas, pavilions and awnings have separate services because their roof openness, scale and attachment methods differ.
Attached vs Freestanding
An attached cover uses the house for part of its support and therefore requires careful connection and weather detailing. A freestanding cover uses its own posts and beams but can need additional footings.
The customer should decide which relationship makes sense for the patio and house before materials are ordered.
Posts, Beams & Roof Panels
Posts establish the elevation and footprint, while beams and roof panels create the drainage plane. The frame needs to remain square and properly supported as panels are installed.
Large roof sections require controlled handling. Missing structural hardware should be replaced with specified components rather than improvised.
House Attachment and Flashing Boundary
Where a cover attaches to the house, the connection must support the structure and prevent water from entering the wall or roof interface. Flashing and siding details can be as important as the visible patio cover.
No guarantee is made for a simple ledger attachment without reviewing the actual exterior wall and roof geometry.
Footings, Drainage & Weather Loads
Posts need support appropriate to the cover and site. Roof slope and drainage should direct water to a planned edge or gutter rather than toward the house.
Snow, wind and approval requirements can affect structural design. Those regulated considerations should be confirmed for the actual project.
FAQ
How is a patio cover different from a pergola?
A patio cover has a more complete roof for weather protection.
Can it attach directly to the house?
It may, but structural and flashing conditions need planning.
Are footings included?
They should be defined as part of the project when required.
