If you want a covered outdoor space beside your home, the SHPAI 12-by-16-foot wall-mounted hardtop gazebo is the clearest match because its listing specifically describes a wall-mounted, lean-to design. The other four options are adjustable-roof or louvered pergolas; their supplied details do not confirm that they attach to a house, so check installation requirements before choosing one. The 10-by-12 model suits a smaller footprint, while the larger PURPLE LEAF models are worth comparing for more coverage.

SHPAI Wall-Mounted Hardtop Gazebo

Best for: Homeowners whose primary requirement is a roofed structure designed to sit against a wall. This is the strongest match for an attached-to-the-house search because the listing describes it as wall-mounted and lean-to. Its 12-by-16-foot footprint is described as spacious for gatherings, barbecues, or relaxing.
The product information specifies a weather-resistant hardtop, sloping galvanized steel roof, rust-resistant metal frame, and upgraded gutter system intended to drain water. It also states a 60 mph wind rating, 22 PSF snow load, and 2,500-pound maximum load capacity.
Limitation: Confirm the mounting surface, installation method, and local building requirements before purchase. The listed load figures do not replace site-specific advice or installation instructions.
10-by-12 Adjustable-Roof Pergola

Best for: Buyers with a more compact patio who want an adjustable roof. The product name identifies a 10-by-12-foot size and thick aluminum frame, and describes the roof as adjustable and intended for all-weather use.
Choose this option if those listed dimensions fit the available area and you want roof adjustment as a feature. It was selected as the smallest stated footprint among these choices, making it easier to compare for tighter spaces.
Limitation: The supplied product details do not confirm wall-mounting or attachment to a house. Check the mounting configuration and installation instructions if an attached structure is essential.
12-by-16 Adjustable-Roof Pergola

Best for: Buyers comparing a mid-size adjustable-roof pergola. The listed name gives a 12-by-16-foot size, thick aluminum frame, and adjustable roof; those details make it a larger-footprint alternative to the 10-by-12 model.
Consider it if you need more listed area than the smaller option and prefer an adjustable roof design. The supplied product information does not describe installation hardware, wall attachment, or specific weather-load performance.
Limitation: Do not assume it attaches directly to the home based on the search term. Verify whether the intended installation is freestanding or wall-mounted before deciding.
PURPLE LEAF 12-by-20 Louvered Pergola

Best for: Buyers who want a long, 12-by-20-foot layout with adjustable louvers. The product name identifies durable aluminum and adjustable louvers, offering a stated roof-adjustment feature for users comparing louvered styles.
This option is better suited to a larger outdoor area than the 10-by-12 and 12-by-16 models. It was selected for its longer listed dimension and explicit louvered-roof description.
Limitation: The supplied details do not establish that this pergola is designed for wall mounting or specify wind, snow, or rain-load limits. Check the product installation information for those requirements.
PURPLE LEAF 14-by-20 Bronze Pergola

Best for: Buyers comparing the widest listed pergola size here. The product name describes a 14-by-20-foot outdoor louvered pergola with large aluminum roofs and a bronze finish.
Choose this if the larger stated dimensions suit your patio and the named finish fits your plans. Compared with the 12-by-20 PURPLE LEAF model, it is listed as wider; both are large-format choices.
Limitation: Product details provided here do not confirm wall-attachment hardware, installation type, or load ratings. Verify those points rather than treating “covered” or “pergola” as proof that it can attach to a roof or wall.
Buying Guide: Choosing A Covered Pergola Beside Your Home
Does the product actually attach to the house?
Check whether the listing says wall-mounted, lean-to, or attached, and review the installation manual for the required mounting surface and hardware. Among these choices, only the SHPAI model is explicitly described as wall-mounted. Do not assume an adjustable-roof pergola can be fastened to a house because it appears near the home in a product photo.
Which size fits your patio?
Measure the available width and projection from the wall, and account for doors, windows, walkways, and roof eaves. Compare the listed footprints: 10 by 12 feet is the smallest; two products are 12 by 16 feet; and the PURPLE LEAF options are 12 by 20 and 14 by 20 feet. Confirm whether listed dimensions describe the frame’s outside measurements.
Should you choose a hardtop or adjustable louvers?
A hardtop provides a fixed roof style, while adjustable-roof and louvered products are presented as adjustable options. The supplied information does not establish how fully the louvers close or how each model performs in specific weather. Review the manufacturer’s directions for operation, drainage, and weather precautions.
What should you verify before installation?
Check local permit and setback rules, attachment points, roof drainage, and the structure’s stated wind and snow limits. Ask a qualified installer or building professional if the house wall or roof framing must support additional loads. Do not rely on general product language as a substitute for site-specific installation requirements.
