A covered deck gives you more time outside—without worrying about harsh sun, heavy snow, or passing showers. Whether you want to enjoy morning coffee year-round or protect your grill and furniture, a roofed structure keeps your space clean, dry, and usable. It also adds value and curb appeal, with custom styles that complement your home’s roofline. We build both open-air and enclosed options, including shingled gables, metal covers, and wood-framed roofs with lighting, fans, or screens.
Adding a roof to your deck extends the outdoor season and transforms how you use the space. With a permanent cover, you can relax outdoors even during light rain, strong sun, or early snowfall. Covered decks also protect your investment—keeping your deck boards, railings, and furniture in better shape for longer. And they improve resale value with the look and function of a true outdoor room. Whether you prefer open beam, vaulted, or fully enclosed, we build it to last.

Every project begins with a site assessment. We inspect your existing deck or patio, check elevations and attachment points, and design a structure that aligns with your home’s style and code requirements. For new decks, we integrate the cover into the framing from day one. For existing decks, we reinforce framing and posts to support roof loads. From permits to final shingles, we handle the entire process—ensuring you get a clean, safe, and attractive finished product.

We build roofed structures using durable, weather-rated materials suited for New Hampshire homes. Choose from asphalt shingles to match your home, standing seam metal for modern flair, or translucent polycarbonate for light-filtering protection. Framing options include pressure-treated wood, cedar, or wrapped columns for a finished look. For added comfort, we can pre-wire for lighting, fans, or heaters. Whether it’s a simple lean-to or a vaulted ceiling with exposed beams, we’ll match your home’s aesthetic with smart, long-lasting construction.
A patio roof is only as strong as its structure—and in New Hampshire, that means planning for snow loads, wind uplift, and freeze-thaw cycles. We install code-compliant support posts, bracing, and footings deep enough for frost line requirements. Roofing materials are selected for durability and drainage, with sealed flashing to protect your home’s siding. Whether it’s snow in February or downpours in May, your covered deck will stay secure, dry, and low-maintenance through every season.
