Covered Pergola Patio Roof Ideas

A pergola is a non-traditional style roof in that its open and provides filtered shade than protection from the elements. This freestanding structure is supported by posts or columns and the roof is made up of evenly spaced slatted beams.

Plan your pergola carefully; these structures can look large and imposing. You dont want your new patio roof to look out of proportion with the rest of your home. For a traditional look, you can build yours out of wood. For a more modern solution, use vinyl as your building material. It will be resistant to decay and require less maintenance.

Dont be afraid to mix materials. You could create the columns out of elegant stonework. Then use wood for the upper framework of your pergola.

Your completed roof will provide plenty of shade, but if you want a bit more, then let a vine plant grow on your new roof. This will create a filtered light effect and blend in perfectly with a country or traditional home.

Building Over An Existing Slab

How To Build A Gable Roof Over A Patio

If you are building an overhead to cover an existing patio, you must first determine if local codes allow setting it directly on the slab and, if so, is the concrete thick enough to support the weight. Otherwise, you will have to create original footings for the overhead. If you need help with this project, get free bids from local patio roof construction pros.

In many areas, an overhead on a concrete slab is allowable if the slab is at least 3 1/2 inches thick and each post can support combined live and dead loads of up to 750 pounds .

To secure an overhead to an already-existing slab, you must place each post in a post anchor. Standard anchors work with rough and surfaced 4-by-4, 4-by-6, and 6-by-6 posts; any other size anchor will have to be specially ordered.

To install a masonry anchor, use a drill with a masonry-bit attachment to make a hole large enough for a 1/2-inch expanding anchor bolt. After inserting the bolt, secure the post anchor by adding a washer and nut and tightening with a wrench. Cut the end of the post square, sit it in the base, pre-drill holes in the post, and then nail the anchor to the post.

Another way to fasten the post anchor is by securing a short piece of threaded rod in a hole with epoxy cement. Start by drilling a hole slightly larger than the threaded rod.

Installing The Ledger Board

First I removed the 1/4 plywood dressing right below the drip edge and saw a very solid framing 2×4 underneath, perfect for attaching the ledger board, which attaches the cover to the roof frame. The local building code required a 2×6 ledger board, which meant I had to saw off two inches of wood from the top of the bay windows box. Next, I pre-drilled 1/8 holes, 6 inches apart, in the ledger board, because it was treated lumber and the deck screws would need a little help getting started. After attaching the ledger board with 4 decking screws, I used a large staple gun to staple the phone, internet, and cable lines to it, on the inside toward the house, to better protect them from the weather.

What Should You Consider When Building Your Own Deck Cover

The first thing youve got to think about is how the deck roof is going to sit alongside your existing home. If your deck has a gap between it and your house, this might not be a problem as you can simply build a stand-alone deck cover. However, many decks are right next to the back of your house, which raises a few issues.

Joining a home-made roof to your existing roof might require a level of expertise that you dont really have. In this scenario, it might be a good idea to hire a professional to get the job done for you.

It will probably only be a couple of days work and might not cost as much as you think.

One alternative option that you can do yourself is to have a slightly higher roof on your deck, so that its above your main roof slightly, and overhangs.

That way any rainwater can roll off of your deck roof an onto your house roof, feeding into your main guttering system. Thats one of the main issues with building your own roof cover, where is the rain water going to go? If you have a roof at the same height, it will have to join somehow or else therell be a gap between the two constructions for water to come down onto your decking.

Some people also like the feel of having a higher deck roof, so this could be an option you might want to look at.

When you start building your roof over the deck, try and get some material that compliments the decking. You might want to use the same wood, or something else. Treat it with the same products to give it a similar finish.

Patio Roof Lighting Ideas

Creating layers of light is the key to creating a lighting scheme for your outdoor space. Strive to have an ambient, accent, and task lighting fixture. Ambient lighting is the generalized light that illuminates the entire space. You can do this by installing overhead lighting. Pendants, chandeliers, ceiling fan lights, and semi-flush/flush-mounted lights. These fixtures will give you a gentle wash of light over your entire patio.

Accent lighting is more decorative and will highlight specific aspects of your patio. This type of lighting is created by installing track lighting, scones, rope lights, string lights, or LEDs. You could use a track light in the ceiling pointed to your outdoor fireplace or you could have lights that point toward your stairs to make them safer at night.

The third type of lighting is task lighting. This is the light youll use in areas where tasks get performed. If your patio roof covers an outdoor kitchen, grill, or bar, youll want to focus this type of light there. The light should remove shadows and make it easier to see what youre doing. Try pendant lighting to focus the light where you need it most.

  • Lay The Sleepers And Predrill For Concrete Screws

    Design of a roof addition over an existing concrete patio in Bozeman, MT part 1

    The sleepers dont have to be level; they can follow the slope of your patio. But they do need to form a flat plane. If your patio is in good shape, youll get a flat plane automatically. If your patio has ridges and sunken areas, youll spend lots of time fussing with shims.

    To preview the situation, lay a straight board across the patio in a few spots. Look for the highest hump in the patio and fasten your first sleeper there. Then work outward from the high spot, adding sleepers and checking for flatness along each sleeper and across them. Add shims to raise low spots.

    Drill through sleepers, spacers and into the concrete with a hammer drill, then drive in concrete screws. Overhang the sleepers along one edge of the patio and trim them to exact length later.

    Roof Decks Are Ideal For Enjoying Cool Evenings But Adding One Wont Be A Breeze

    Private roof decks, the envy of the neighborhood when the weather is nice, are a trendy accessory in newly built townhouses in town-center-style communities in the suburbs. Adding a roof deck to an existing home is a bit trickier. It might be tempting to just slide open a tall window and shimmy out onto a flat roof, but to be safe and to have a truly functional roof deck, youll need to spend time and money.

    Most roofs werent designed to have people walk on them, much less put furniture on them and entertain up there, said Ethan Landis, co-owner of Landis Architects/Builders in the District. Adding a roof deck is like creating a great outdoor room, which is especially nice if theres no good backyard. But you have to evaluate the condition of the existing roof first.

    Hiring a designer with experience adding roof decks to other homes in your neighborhood can make the project easier and result in a deck thats not only attractive but also structurally sound and compliant with zoning and fire codes.

    Each roof deck project is one of a kind, Landis said. They all have logistical challenges, and many of the ones weve built are on homes in a historical neighborhood, which means they need to be invisible from the street.

    Other issues include skylights, chimneys and air conditioners that might need to be moved or built around.
