Common Ways to Add Space
- Widening or lengthening an existing slab or porch deck
- Adding a covered roof over an open patio
- Wrapping a front porch around a corner of the house
- Stepping down to a new paver or stone patio from an existing porch
For patios specifically, our patio extension page goes into surface options.
Making the New Section Look Original
The most important detail is the roof. We match pitch, shingles or metal, fascia and ceiling material so the extension reads as part of the house, and we flash the tie-in carefully to keep water out. Floors are matched as closely as possible, or deliberately contrasted with a border. Columns, railings and trim are sized to match. Slab extensions are doweled or isolated so old and new concrete move without cracking each other.
What an Extension Costs and How Long It Takes
Covered porch and patio extensions commonly range from about $3,000 to $15,000, driven by size, roof complexity, materials and any electrical work. Most projects take two to four weeks from start to finish, including any permitting. Want to keep bugs out once it is built? Consider making the new space a screened-in patio.
Materials That Last Here
Composite decking, sealed concrete and pavers resist moisture and need little care. Fiberglass or PVC columns and trim do not rot. A properly vented roof keeps heat from building up under the ceiling. If you are adding fans and lights, plan for them now; our porch lighting and sound page explains options.
Common Questions
Is it cheaper to extend a porch than build a new one?
Often, yes, because the house connection and part of the structure already exist. The savings depend on the condition of the current porch and how well it can be matched.
Will the new roof leak where it meets the old one?
Not if it is properly flashed and tied in. That connection is the most important part of the job, and we pay close attention to it.
Can I customize the design?
Yes. You can choose size, roof style, flooring, columns, railings, ceiling finish, lighting and fans. We show you options during design.
Are the materials weatherproof?
We use materials suited to Mississippi heat, humidity and rain, such as composite decking, sealed concrete, metal or shingle roofing and rot-resistant trim.
