Add A Roof Of Lattice To An Existing Pergola

Your first step will be to decide whether to use wood or metal for your lattice. If you are in a humid climate, wood may be more susceptible to rotting and cracking, while metal will last much longer.

Next, decide if you want a painted or stained finish on your pergola roof. A painted design can be as simple as stripes or squares in contrasting colors; it’s also possible to make more elaborate designs using stencils and spray paint.

A stained finish is often easier than painting because there is no need for masking tape around the edges of each plank before staining them individually (which can lead to bleeding between planks).

However, stains tend not last as long as paints so if longevity matters most consider choosing a color that best matches the existing structure of your pergola so that it blends seamlessly into its surroundings

Use Shade Sails On Your Pergola

Another option is to install shade sails on your pergola. Shade sails are easy to install and can be used as a shade cover or as a windbreak.

They’re available in various colors, styles, and materials, so you can choose one that suits your taste and needs.

If you want to position the sail close to the pergola, attach it directly onto the structure with clips or ties. You can also hang it from another nearby structure like a tree branch or roof overhang if you’re worried about damaging your pergola by attaching anything directly to it.

Add A Corrugated Steel Roof To Your Pergola

If you want to add a corrugated steel roof to your existing pergola, you’ll need the following items:

Metal brackets (used to attach the roof structure to the structure of your pergola)
Sheet metal screws (to secure brackets)

Roofing felt or tar paper

Once you have all of your supplies, follow these steps:

Use your measuring tape and pencil to mark out where on top of your columns each bracket will go.

You’ll want them spaced evenly apart so that they support each other as well as hold up any potential weight placed on top of them. Think about how much weight might possibly be added roofs can’t handle a lot!

Proper alignment of pergola posts is essential for structural integrity and visual appeal. Take a look at our recommendations on how to align pergola posts to ensure a stable and beautifully balanced pergola structure.

Add Solid Panels Or Shingles To A Wooden Pergola

If you’re going with solid panels, use a hammer and nails to secure them. If you have a nail gun, that will work too! With shingles, it’s easier to use the nail gun since shingles aren’t self-securing like panels are.

Once the roof is in place, make sure everything is level by using a level on top of each panel as you go.

Create A Shade Canopy For The Pergola

A shade canopy can be created to cover the pergola. A canopy can be made of canvas or other material, and it can be attached to the frame using rope or chain.

Use rope or chain to secure the end of the fabric to each post at eye level.
Cut out a square shape in one corner of your fabric, and attach it with more rope or chain across all four posts in an X-shape (see image).

Brand	Canopy Type	Material	Features
Coolaroo	Shade Sail	HDPE Fabric	UV protection, breathable material, various sizes
Sunjoy	Retractable Canopy	Polyester Fabric	Adjustable coverage, motorized or manual operation
Garden Winds	Replacement Canopy Cover	Ripstop Fabric	Custom fit, easy installation, replacement option

Quik Shade	Instant Canopy	Polyester Fabric	One-piece frame, multiple sizes and colors available

Paint Your Old Vinyl Pergola With Deck Stain Or Water Sealant

Paint your old vinyl pergola with deck stain or water sealant. Once you’ve got the roof on, it’s time to give your pergola a fresh coat of paint.

You can use just about any type of paint for this project even leftover paint from other projects in your home.

Just make sure that whatever paint you choose is safe for vinyl fabrications and will withstand exposure to the elements (and rain).

Use a roller to apply the paint evenly across all surfaces of the pergola. Use a brush to get into tight corners and edges so they’re coated well, too. Let dry 24 hours before letting people use it again!

Cover Your Existing Metal Pergola With Bamboo Roofing Material

The next step is to cover your existing metal pergola with bamboo roofing material. Bamboo is a fast-growing renewable resource that can be used for roofing, decking, fencing and much more. It’s strong and durable. You can nail it down or attach it with screws if you prefer (we chose the latter).

Brand	Material Type	Pros	Cons
Cali Bamboo	Bamboo Reed	Eco-friendly, natural appearance	Requires regular maintenance and sealing
Forever Bamboo	Bamboo Panels	Easy installation, durable and weather-resistant	Limited design options
Backyard X-Scapes	Bamboo Thatch	Tropical aesthetic, provides shade and insulation	May require additional framing for support
Tiki Brand	Bamboo Roll	Quick and convenient installation	Limited coverage area per roll
Sunset Bamboo	Bamboo Matting	Versatile and customizable, can be trimmed to desired size	Requires proper sealing and protection against weather elements

Add A Roof Made Of Old Barn Wood Planks To Your Pergola

The roof you choose can be made of old barn wood planks. You will need to buy a saw and cut these planks to length, then attach them to the pergola with screws or nails. You may want to use a hammer and nails for this task if you do not have access to power tools in your area

Attach Pvc Plastic Panels To Pergola

Use the screws or zip ties to attach the PVC plastic panels to the pergola, making sure that they are waterproof.

If you are using zip ties, it’s a good idea to prime them first so that they don’t stick together and make holes in your roof. Use a drill bit slightly larger than the screws you’re going to use and drill holes into each panel at least every 18 inches (46 cm).

Attach Aluminum Sheeting Over The Existing Wood Slats In The Pergola

Once the aluminum sheeting is in place, attach it to the pergola frame with screws or rivets. You can do this by drilling holes through your aluminum sheets and into the wood slats below. Or if you’re not worried about damaging your existing pergola, simply use strong adhesive to stick the pieces together.

The only remaining step is to paint or leave your new panels raw; whichever option you choose will depend on whether they’ll be visible from inside or outside of your home. If you want them to be visible from inside, consider lighting up their tops with solar lights!

Attachment Method	Pros	Cons
Screw Fastening	Secure and durable attachment	Visible screw heads
Rivet Installation	Strong and reliable connection	Requires specialized tools
Adhesive Bonding	Clean and seamless appearance	May require surface preparation and careful application
Clip System	Concealed fastening for a clean look	Specific clip system compatibility required
Snap Lock Mechanism	Quick and easy installation	Limited flexibility for adjustments or modifications

Use A Canvas Canopy Over The Existing Pergola Frame

A canvas canopy is an easy way to add shade to your existing pergola. These canopies are lightweight and easy to clean, making them a popular choice for patios and outdoor dining areas. They’re also durable and inexpensive, so you won’t need to replace them frequently.

Add Shade Cloths Over The Top Slats Of Wooden Or Metal Pergolas

You can add shade cloths over the top slats of wooden or metal pergolas. Canvas is a good choice for shade cloths because it’s easy to install and remove, it can be painted to match your home, and it’s durable and long lasting.
