Whether you're looking to shield your deck from harsh sun, keep your patio dry in the rain, or create a cozy year-round outdoor space — we build high-quality covered decks and patio roofs made for Maryland homes. At Alliance Deck Builders, we combine local craftsmanship, code-compliant structures, and design flexibility to protect your space while enhancing its style. Every cover is built to last and tailored to your layout, materials, and needs.
A well-built patio roof or deck cover lets you enjoy outdoor living no matter the weather. Our structures are engineered for Maryland’s climate — providing UV protection in the summer and shielding you from snow and rain in colder months. Whether attached to your home or freestanding, we offer fully customized options using wood, composite, or metal roofing systems to match your home’s aesthetic and structural needs.

Increases shade and comfort for outdoor furniture
Designed to match your home’s look and layout

From intense summer heat to freezing winter rain, Maryland homeowners need outdoor covers that do more than just look nice — they need to perform. We use durable materials like pressure-treated wood, standing seam metal, and weather-resistant composites to ensure every covered deck or patio roof stands strong for years. With options like recessed lighting, ceiling fans, or skylights, your space becomes functional, beautiful, and ready for all seasons.

GET MORE FROM YOUR OUTDOOR SPACE
Whether you're hosting weekend cookouts, relaxing with a book, or just enjoying the view — a well-placed roof transforms your deck into a space you’ll actually use. We build patio covers that extend your living area without cutting off airflow or natural light. Choose from solid roof systems for maximum weather protection or open gable styles that maintain openness while blocking harsh sun. Every install is engineered to blend with your home and exceed code requirements.
We take the time to understand your space, your goals, and your budget — then design a deck cover that works for all three. From classic wood beam styles to modern aluminum roofs, we tailor every build for Maryland’s weather and your outdoor lifestyle.

Custom-Fit Designs: Every roof is built to your deck’s exact shape, slope, and material needs — not a prefab kit.
Built for Maryland’s Weather: From heavy snow to scorching sun, our materials stand up to all four seasons.
Options for Every Style: Choose gable, shed, or flat roof styles — with trim, lighting, and finish upgrades available.
