Patio cover and carport roofing for Los Angeles homes

Patio covers and carports are low-slope roofs that get forgotten until they leak onto the furniture or the car. We re-roof them with the right low-slope system, repair or replace aluminum and wood covers, and tie them into the house so water stays off the wall.

Patio cover roof on a Los Angeles home
Quick answer

Patio cover and carport roofing in Los Angeles covers re-roofing attached and freestanding covers, replacing worn carport roofs, and repairing aluminum and wood structures. Most covers are nearly flat, so we use low-slope membranes or panels and flash the connection to the house, where many patio cover leaks begin.

A patio cover is a roof, just a flatter one

Patio covers and carports are usually built with very little slope, and many were roofed with rolled roofing or shingles never meant to sit that flat. Water lingers, seams open, and the ledger where the cover meets the house lets water run down the wall. Sun and palm debris do the rest.

We look at the structure first: posts, beams, rafters and the ledger connection. Then we choose a covering that suits the slope, such as a modified bitumen or single-ply membrane, or metal panels on steeper covers. If the house roof needs work too, see roof replacement.

Cost factors

What patio cover and carport roofing costs depends on

These small roofs are priced by area and structure. Five things set the cost:

  • Covering type

    Membranes and metal panels price differently.

  • Structural repairs

    Rotted rafters, beams or posts add carpentry.

  • Ledger flashing

    Opening the wall to flash the connection properly.

  • Drainage

    A gutter or downspout at the front edge.

  • Size

    Setup is fixed, so small covers cost more per foot.

Re-roofs, replacements and structural repairs

Patio cover re-roofing

We strip the old covering, repair soft sheathing and rafter tails, and install a low-slope membrane or metal panels suited to the cover's pitch. The ledger gets new flashing tucked behind the wall covering, and a drip edge and gutter carry water off the front instead of onto the patio. If the cover is too flat for any roofing to drain well, we can add a slight taper with tapered boards so water reaches the gutter instead of sitting in the middle.

Carport roof replacement

Carports take heat, sun and debris with no attic to buffer them. We replace worn roofing, rusted metal panels or failed membranes, fix sagging framing, and add drainage so water leaves at one edge instead of dripping on cars and walkways. On freestanding carports we also check the posts at the base, where concrete, water and steel meet and rust starts first, because a solid roof on weak posts isn't a repair that lasts. It's a quick check that saves a bigger job.

Aluminum and wood cover repair

Aluminum patio covers leak at panel seams, fasteners and the house connection; wood covers rot at rafter tails and posts. We reseal or replace aluminum panels and fasteners, repair or replace rotted wood members, and reset posts that have shifted. Aluminum covers are light, so we don't load them with heavy roofing; where a homeowner wants a quieter or cooler cover, we'll talk through insulated patio panels that fit the existing frame and still shed water well.

Roofing in Los Angeles

Los Angeles roofing work calls for coverings with fire, wind and cool-roof ratings, and the permit is typically pulled by the contractor. Many attached patio cover and carport rebuilds fall under that process, and LADBS roofing permits typically run $250-$1,200, about $370 for a standard home. We check whether your scope needs one and include it in the written price from the start.
