How Do You Build A Thatched Roof Gazebo?

A thatched roof gazebo is an elegant and functional addition to your backyard. It provides shade for outdoor activities, a place to relax with friends, and it can even be used as a small workshop. 

If you’re not sure where to start or if you’ve ever wondered how people build these structures from scratch, here’s everything you need to know about building your own thatched roof gazebo!

Thatched Roof Gazebo for Outdoor Picnic Table
Building a thatched roof gazebo requires careful planning and preparation.
Thatching materials such as palm leaves or grass reeds are commonly used for creating the roof.
A solid and sturdy frame is essential to support the weight of the thatched roof.
Proper maintenance and periodic rethatching are necessary to ensure the longevity of the roof.
Thatched roofs provide a unique and charming aesthetic to outdoor spaces.


The first step in building a gazebo is to lay the foundation. The foundation should be level, able to support the weight of the structure and strong enough to hold it up. 

For example: if your ground is soft or uneven, you may need wooden boards as a base for your gazebo flooring (costs will vary based on materials). 

You can also use concrete blocks instead of dirt or sand when building your foundation depending on how much rainwater drains through your land; this way, water doesn’t seep into the soil around where you’ll be constructing your gazebo.

However, if there’s already concrete nearby then simply use that!

You’ll need to construct a frame for the roof of your gazebo. This will consist of beams and posts, which are held together with a ledger board. 

If you’re using treated lumber for this project, you can follow these measurements:

  • Use 5×5 or 6×6 beams for the corners
  • Use 2x4s for braces and sills under any floor joists that span more than 2 feet across (the joists should be spaced every 8 inches).

For posts that aren’t supporting rafters or trusses, use 4x4s; put them at 16-inch intervals along each side wall; make sure they’re plumb (straight up and down), level with each other, and firmly attached to the ground with concrete piers that extend 12 inches below grade. 

If you have trusses in your roof structure and if they support rafters as well as themselves then go ahead and use 6x6s instead of 4x4s on all sides!

Frame TypeDescription
Steel FrameSturdy and durable frame made of steel, providing excellent strength and stability. Ideal for heavy-duty applications.
Aluminum FrameLightweight and corrosion-resistant frame made of aluminum, offering easy portability and resistance to rust. Perfect for portable and outdoor use.
Wood FrameClassic and aesthetically pleasing frame made of wood, providing a natural and charming look. Suitable for traditional and rustic settings.
PVC FrameLightweight and weather-resistant frame made of PVC (polyvinyl chloride), offering durability and low maintenance. Popular for outdoor structures and canopies.
Wrought Iron FrameElegant and ornate frame made of wrought iron, known for its decorative appeal and robust construction. Great for adding a touch of sophistication to outdoor spaces.

The Thatch/Roof

Thatch is a natural material that is made from the leaves of the palm tree. The leaves are woven into a dense mat, which is then placed on top of the frame. 

The thatch is secured with wooden pegs and wire nails so that it doesn’t move around or blow away in high winds.

Alignment and Adjustment

Now is the time to check that everything is level and square. If you’re building a gazebo with a sloping roof, this step will be easier than if you are building an A-frame gazebo. 

If your frame is off kilter, adjust it so that it’s as flat as possible before proceeding with the next step.

After leveling your frame and making sure it’s square, make sure all of your walls are straight up and down. If they aren’t, use shims or boards to make them so (I used 4×8 sheets of plywood). 

And finally, make sure that all four walls are even in length by either measuring from corner to corner using a tape measure or using some sort of level (carpenter’s level or laser) on each side until both ends are even with one another.

Add Up the Walls

Now that the frame is done, it’s time to add the walls. If you’re doing a gazebo with an arched roof, use your flat boards and attach them to one another using metal brackets attached at an angle on both sides of each board. 

This will make a sturdy arch shape that will support your ceiling and prevent any collapse of your structure in high winds or storms.

When you’re attaching your walls to their foundation (if you’re doing this), make sure that they are level and square with one another before attaching them together so that there won’t be any gaps between each wall when it’s finished! When all four walls are built, it’s time for step 6: adding up the ceiling!

Wall MaterialDescription
Vinyl SidingDurable, low-maintenance, and weather-resistant wall material commonly used in residential construction.
BrickClassic and durable wall material known for its strength, longevity, and aesthetic appeal.
StuccoVersatile and customizable wall material that can be applied in various textures and colors, offering a unique look.
Fiber CementStrong and resilient wall material made from a mixture of cement, sand, and cellulose fibers, providing excellent durability and fire resistance.
Wood CladdingNatural and visually appealing wall material that adds warmth and character to a structure. Requires regular maintenance to preserve its condition.

The Door and Windows

You should make your door and windows from wood. The door should be at least 2 feet wide, and the windows should be at least 1 foot wide. 

The doors and windows are placed on the sides of the gazebo, so they can be accessed from inside or outside. 

In order to create privacy in your gazebo, you will need to place them at different heights; this will allow people sitting inside to see out while those standing outside cannot see inside easily.

The Roof Peak (Ridge)

This is one of the most important steps in building your gazebo. Attaching the ridge boards to the frame, as well as adding fascia boards to hold in place a thatch roof. 

The ridge board will be installed first using a nail gun and square cut nails. You’ll want to make sure that you have built your gazebo walls all the way up so that they’re flush with where you will be attaching your ridge board.

To install a thatched roof, you need to have at least 2 foot on each side of where your peak will be (the point where one side meets another). 

You also need an additional 6 feet on either side of this area for attachment purposes below ground level and above ground level respectively. 

The extra 6 feet allows for plenty of room for tacking down with washers and screws into hidden joists or rafters underneath those surfaces; this makes installation much easier!

Attach the Ridge to the Frame and Walls

Now you’re going to attach the ridge to the frame and walls. This is done with a hammer and nails.

Make sure that you place the ridge at an angle so that it slopes towards where your gazebo is being built. 

This will help in drainage during rainy weather, as well as make your roof watertight if there are any leaks in between them.

Attachment OptionDescription
Bolts and NutsSecure attachment method using bolts and nuts for maximum stability and structural integrity.
Brackets and ScrewsQuick and convenient attachment using brackets and screws, allowing for easy installation and adjustment.
ClampsVersatile attachment option using clamps, providing flexibility and adjustability during installation and maintenance.
WeldingPermanent attachment method utilizing welding techniques for a strong and durable connection between the ridge, frame, and walls.
Adhesive or SealantNon-invasive attachment method using adhesive or sealant to bond the ridge to the frame and walls, providing a seamless and watertight connection.

Add Fascia Boards to Hold the Thatch in Place

At this point in the project, you’ll have a basic structure with a framework and a roof. The next step is to add fascia boards to hold your thatch in place.

Attach fascia boards to the frame of your gazebo. These are the horizontal pieces that run along the top of each side wall, attaching at both ends and across their width where they meet at corners or with other pieces of wood, depending on how your gazebo was designed. 

Use screws or nails for these connections; however, be careful not to over-tighten them because this could cause damage or even break off fascias if they’re too thin for their attachment points.

Attach fascia boards around all four sides of your gazebo’s peak (the pointy section atop its roof), using screws or nails again for secure fastening so long as these don’t go through into any interior parts without being covered up later by shingles or other materials used in construction.”

Finish the Thatched Roof Gazebo with Mushroom Sealer and Stain

Mushroom sealer and stain is a water-based product that protects the wood from weather damage and insects. It helps prevent rot and mildew, which can cause the roof to leak.

After you have completed all of your framing, finishing touches, and construction work on the gazebo’s thatched roof, it’s time to apply your mushroom sealer and stain. The directions will differ depending on what brand or type of mushroom sealer/stain you are using, but in general:

Wear gloves for this step!

Apply two coats of mushroom sealer/stain per side (the top sides and bottom sides) of each piece with an applicator brush in even strokes that overlap slightly at each end so no area goes without coverage.
