Let’s just say, if you have a pergola in your home, honey, you need roofing over it. Your pergola may be covering a sitting area in the garden or a patio in your home but in order for it to be utilized. You need to have roofing to enjoy the benefits of your pergola throughout the year. Putting a roof over it will also increase its usage and durability in harsh weathers as well. You can purchase all kinds of roofing from Marco Roofing since they have a huge variety of it.
One way to go is the clear polycarbonate roofing which will block the UV lights from entering while giving you a good enough time of sunlight. This technique will make your patio furniture last longer and would not be bleached by the rays of the sun.
Steps to installing
Gather up your supplies and tool box because we are about to begin the installation.
· Install the Purlins
Purlins need to be installed at the top of the pergola, you can even paint them before hand to match the pergola. If your pergola panels go vertical, make sure to install your purlins in a horizontal manner to give a nice cross. Also try that you have another set of hands to help you with this since it can be hard for a single person.
· Install the closure strips
Closure strips are essential since they hold the roofing in place. These are attached to the bottom of your installed horizontal purlins. These do not require much labor because they just snap right onto the ends. However, to secure these, screwing up from the header of the pergola into the purlin is required. It is a wiser decision to add on a screw at each cross of the crossing beams of the pergola and the purlin. The vertical closure strips just ran at the ends of the horizontal closure strips.
· Installing the clear polycarbonate roof
We know that the preparations took a while but now we have finally reached to the point where we install our polycarbonate roof. Carefully measure your roofing sheets according to the size of your pergola and cut them even more carefully by leaving a leverage at the bottom to hangout of the end of the pergola a little bit.
Now is when you place your measured and cut roofing sheets on top of the pergola. First allow them to sit onto the vertical and horizontal closure strips that you have fixed and once they are where they are supposed to be, begin screwing them in. before screwing them on, make sure you predrill with a ¼” drill at first to allow room for contraction and expansion at different temperatures, or lese there will be unwanted cracks. Now you can fasten the roofing sheets by screws into the grooves but leave the last groove where the next panel would overlap it.
As tried and tested before, installation of such a roof is not actually hard and is pretty much a DIY, but it does require a another set of hands and a favourable weather to work in.
