Many homeowners have determined that a pergola, patio, or verandah addition is the ideal way to utilize their outdoor spaces. Others are trying to figure out how to weatherproof their swimming pools without enclosing them. Polycarbonate roofing is one of the best decisions you can make because it enables you to take advantage of a lot of natural sunshine without worrying about extreme heat, UV rays, rain, or glare.
A pergola is a garden building that provides shade. It can also be called an arbor if it is placed over a walkway, a place to stand, or benches and tables. Pergolas can be a genuinely wise investment for many extensive and medium-sized gardens.
Pergola with polycarbonate roof
It is also possible to waterproof a polycarbonate-roofed pergola. Waterproof tape is put on the roof joints and hinges for this aim. Pergola roof panels have louvered slats. Additionally helpful in keeping out rain or flood, these slats. But most contemporary pergolas need some roofing. These slats control light transmission and ventilation.
The best option is translucent polycarbonate sheets, which can occasionally be constructed of wood or another material. Both sun and rain can be used with this structure.
The thickness of the waterproof pergola with polycarbonate roof
There are numerous sizes of polycarbonate sheets. The most petite sizes, like 4mm and 6mm, are too small and light for pergola roofs, but the most significant sizes, like 25mm and 35mm, are too heavy and unwieldy. Pergolas often use a 10mm polycarbonate twin wall, which strikes the right size-durability balance.
Because polycarbonate sheeting is so light, this is the case. It may be more vulnerable to wind updrafts as a result. 10mm polycarbonate is often thick enough to endure use outside. However, a 16mm polycarbonate triple wall may be used in windy and wet locations.
Benefits of pergola with polycarbonate roof
Clear polycarbonate panels are highly valued in terms of aesthetic appeal and utility. Apparent panel patio expansions are much more popular among homeowners than wooden roofing. So let’s look at some of the benefits of using polycarbonate patio covers.
In terms of strength, polycarbonate is the very best material. Even the most severe impacts will not cause it any harm. Additionally, it is pretty solid and resilient. Polycarbonate panels are an excellent option for pergola roofing because of this. Your polycarbonate pergola roof panels should last for twenty to thirty years.
· Simple Installation
Panels made of polycarbonate are portable and straightforward to handle. Compared to wooden or glass panels, these panels are simpler to install. The pergola’s gridded design can also better support the polycarbonate panels.
· Climate Resistant
The pergola is a house’s outside addition. The varying weather would most impact the outside roofing. Therefore, the roofing material should be resilient to changing climate. Polycarbonate can withstand extreme weather conditions without suffering damage. Polycarbonate panels don’t have to worry about sun fading or roof blistering.
· Transmission of Light
Compared to conventional glass, polycarbonate allows more light to pass through. The ability to transmit light makes polycarbonate an excellent material for outdoor coverings.
· UV Security
Only the bright sun is entertaining to polycarbonate. It implies that only the sun’s warm rays can pass through. Thus, it is entirely healthy for your body to sit under a polycarbonate roof.
How to construct your pergola’s polycarbonate roof
1. Furring Strips Can Be Added To Create a Roof Slope
As shown above, by cutting graduated furring strips and fastening them to the top of your pergola’s purlins, you can give a slight slope to a flat-roofed pergola. The pitch should be at least 1/8 inch each foot (0.6 degrees), but if you can do it, 1/4 inch per foot (1.2 degrees) is preferable.
Purlins in our pre-made pergola plans are generally set at either six ′′ or 12′′ intervals, making it reasonably easy to determine the thicknesses of the furring strips. Without needing to follow a pencil line, you can set up your circular saw to cut a constant thickness by using a straight piece of scrap wood as a fence and a few clamps. Using the edge of the shoe as a reference, measure the cut thickness using a combination square.
2. Installing the H-Channel
You might have one or more H-channels at the panel seams depending on the size of your pergola. These are used to waterproof the area so there are no leaks between the panels.
The two-piece H-channel used in this polycarbonate roof system features a T-track that must be fixed first. In this instance, it is secured in the pergola’s middle. Before using washer head screws to ensure it, an adequately sized bit was utilized to pre-drill the aluminum T-track.
3. Polycarbonate Panels should be added
As the panels can be a little challenging to handle, this phase is the perfect opportunity to enlist the assistance of a helper. Flip the boards over, so the bottom side is facing up, and remove the protective plastic film that was most likely placed over them to avoid scratches during shipping.
The moisture tape and U-Channel can be added now when it’s simpler to do so on the ground if you’d like. However, if the video is on, debris that gets inside the cells of the multiwall panel during pre-drilling for the panel fasteners will be impossible to remove. As a result, you might wish to wait for the time being.
Moisture Tape and U-Channel
The open cell ends of moisture tape and U-Channel Multi-wall polycarbonate must be sealed with moisture tape to avoid condensation. This roof system’s video covers the cut ends of the panels and has adhesive on the edges.
Aluminum U-channel is used to complete the ends visually. Although it ought to be a relatively snug fit, you might be able to install this with just your hands.
Installing the H-Channel Cap
The H-channel cap installation is all that is needed to be done at this stage. Recall that you placed this aside after applying the weatherstripping gasket previously. Re-climb the pergola, using a plank to help you walk so you don’t damage the roof. Overlap the cap over the T-top.
Use a leaf blower to remove any loose material for a clean installation after clearing the roof of anything.
