Marine, IL

Why Marine homeowners call us

A roof changes how much you use the backyard.

Marine is small-town Madison County at its best - village lots in the core and wide-open acreage past the edge of town, all a short drive from our Edwardsville shop. A pergola or covered patio roughly doubles the evenings a Marine backyard actually gets used - shade in July, cover in a pop-up storm, and a defined room that makes furniture, lighting and a fan possible.

We build across all of Marine - village-core homes, properties along Route 4, and farmsteads and acreage running east toward Alhambra. Every structure is engineered to match the house: roof pitch and shingles carried over on covered patios, cedar sized generously on pergolas, posts on concrete footings poured below the Madison County frost line - never deck blocks.

The most requested Marine build we quote is a gable-roof covered patio with a ceiling fan and lighting, tied visually into the home’s roofline.

Covered structures in Marine

Every way to put a roof over Marine outdoor living.

Cedar pergolas

Generously-sized rough-sawn cedar with clean joinery - shade and structure that looks intentional, not kit-built.

Gable & shed-roof covered patios

Real roofs with shingles matched to the house, vented and flashed correctly where they meet the home.

Pavilions

Freestanding rooms in the yard - vaulted ceilings, fans, lighting, and space for a full outdoor kitchen or dining table.

Attached patio covers

Ledger-mounted covers engineered into the home’s structure - not screwed to fascia and hoped for.

Lighting, fans & screens

Wiring runs planned with the structure: dimmable lighting, ceiling fans, and screened openings where bugs are the enemy.

Deck + pergola combinations

Designed as one structure with one crew and one warranty - not a pergola bolted onto a deck later.

Covered structure questions from Marine homeowners

Real questions we answer at Marine walkthroughs.

Do I need a permit for a pergola or covered patio in Marine, IL?

Yes - covered structures need a building permit from either the Village or Madison County depending on your address; we determine which applies and handle it. We prepare drawings, submit, and meet the inspector - it’s part of every quote.

How much does a covered patio cost in Marine?

Most gable-roof covered patios we build in Marine land between $18,000 and $40,000 depending on size and electrical scope. Cedar pergolas run $6,000 to $14,000, and full pavilions $25,000 to $60,000. Every quote is itemized.

Attached to the house or freestanding - which is right?

Attached covers flow straight off the back door and share the home’s roofline; freestanding pavilions define a separate room deeper in the yard. Lot shape, door height and roof pitch usually make the decision - we walk both options at the free walkthrough.

Will it match my house?

That’s the difference between a structure and a kit. We match roof pitch, carry over shingle color, size posts to the home’s scale, and stain cedar to sit naturally against your siding and trim.

How long does the build take?

Once the permit is approved, most Marine pergolas go up in under a week and covered patios in one to two weeks. Footings are poured first and inspected before framing - we give you the schedule before we start.

Can you add a roof over my existing patio or deck?

Often, yes. We evaluate whether the existing slab or deck framing can carry the structure - covered patios need real footings, so we core through and pour them properly rather than resting posts on a slab that was never designed for the load.
