Installing The Clear Roof Panels

How to build a Pergola – Purlins and Roof Sheets

Now we were finally ready for the roof! All that prep took way more time that actually adding the roof, but I know proper prep is important .

We discovered that our house is not square on the property and made our pergola line up with the fence so it didnt look crooked. So our roofing had to be measured carefully to ensure the overhang was the proper distance all the way down.

So we measured the start and end of every 26 panel and cut each one individually. It ended up being that each panel was 1/4 longer at the back end than the front end. We put the slightly diagonal cut line against the crooked house and left the factory cut line at the overhang.

To cut the panels, we clamped a level to create our cut line and used a circular saw to run right down the edge of it. It was super quick to measure and cut each one. The sound of the saw hitting each corrugation is a little scary at first, but it cuts so clean that there is no need to worry.

After cutting we placed the beautiful clear roof panels on top of the pergola. They just sit onto the horizontal and vertical closure strips. Once in place, it is time to start securing it.

Each screw hole needs to be predrilled with a 1/4 drill bit first to allow for expansion and contraction due to change in temperatures. Without this there might be cracking and that is not desirable! So we used both sets of hands to make quick work of it.

One person predrilled the holes and the other one came in behind with the special screws.

Where To Attach A Patio Roof Ledger

How To Build A Pergola Roof – DIY At Bunnings

On a one-story house, it is often best to attach the ledger for a patio roof just below the houses eaves.

On a two-story house, you can usually tie the ledger into a band joist , located between the floors, as shown below. Find the band joist by measuring down from a second-story window.

Roofing Materials You Can Put On Your Pergola

A lot of homeowners like to stay in their pergola, but when they realize that their pergola can only provide shade and not total protection from outdoor elements, most homeowners decide on adding a little more protection such as a roof.

Roofing materials such as metal, fiberglass, and plastic are quite common and all are excellent solutions. Fortunately, most of these roofing materials are very versatile and can be easily adjusted and cut into different sizes to exactly fit your pergola.

Selecting Materials To Build A Patio Cover

While looks are important, you want to make sure that the materials fit the structure. Since my patio cover was going to have a slight slope, shingles were out. A tar roof would work, but it would be a heavy smell like a BP oil spill. I decided on corrugated metal roofing because its resistant to high winds, is lightweight, and is structurally sound.

Using corrugated metal also allows me to reduce the degree of slope, or roof pitch needed to a mere 10 percent, or a 1-to-10 pitch. This meant the patio cover could start at the edge of the houses roof at a height of eight feet and slope down to seven feet, leaving a clearance of more than six and a half feet between the lowest part of the frame’s headers and the ground at its outer edge.

Corrugated / Flat Panels

A much more cost-friendly solution, it is now possible to buy a whole array of different styles, sizes and materials with various fixings from plain old screws to more optimized solutions that are less likely to leak or make your pergola rot. In order to maintain the same amount of light, in my research, I was looking at clear or lightly tinted panels rather than changing the concept of a Pergola and going for a solid dark roof.

I was initially not interested in using these but having investigated them they are now of real interest. I like them as I could add them to my existing structures and they are compatible with other shade methods, including growing vines and they would still work with the sliding fabric panels if more shade was required.

Having checked some reviews it seems that Fiberglass panels will craze/cloud quite quickly, which will change the appearance and amount of light they allow.

The PVC panels are an improvement but are still quite brittle and susceptible to cracking , although they are more scratch-resistant than polycarbonate.

The strongest and longest-lasting would be the Polycarbonate panels but they are also the most expensive and can last 10-20 years!

Most polycarbonate sheets come with specialist UV coating but for residential applications, it is usually only on one side of the panel. You have to check that it is installed with the UV coating upwards.

Measure The Roof Valley

Metal Roof Pergola

Measure each roof valley from the lower end to the upper end and multiply the result by two, which provides nailers for each side the valley. Count the number of penetrations, such as duct vents and pipe risers that go through the roof. Include 4 feet of stripping for each, which translates to 12-inch-long nailers at all sides of a penetration.

Obtain one-by-three framing lumber for the nailers based on your measurements and calculations. Include 1 pound of 8d framing nails for every 100 square feet of the roof.

Does A Pergola Add Value To A Home

Heres what we tell our customers: yes, a pergola will add market value to any house. Since outdoor living has become more popular than ever, the value of properties with a pergola or a comfortable outdoor space has been on the rise. A safe gauge for a deck or backyard improvement is about 50% 80% for your ROI.

Determine Location Of Rafters

Snap chalk lines on the roof that coincide with the line of each rafter from the lower edge of the roof to the peak. The lines provide references when nailing the stripping. Determine the location of a rafter by a vertical set of nails in the fascia board or by an exposed rafter tail. Measure from one edge of the roof to each location and transfer the measurements across the roof at the peak. Snap lines between each set of upper and lower marks.

Use the lower edge of the roof as a guide and install nailers end to end across the roof, with the lower edge two inches from the edge of the roof. Drive a pair of 8d nails through the wood stripping at each reference line for a rafter. Cut a filler piece to length for the end of the row.

Metal Roof For Pergola Options

Pergola is used in buildings for long ago for different purposes. It provides beautiful walkways, link passages and resting and sitting areas in outdoor of homes. Different pergola or gazebo designs are on hand for selection according to requirement. Pergolas are constructed with roofs or without roofs but with roof pergolas are more secure option. For roofing multiple ways are adopted and metal roofing is one of more effective and durable option. Metal sheets are easy to fix according to the size and shape of pergola. Metal roofs provide more protection and shelter against different harsh weather conditions. Metal roofs for pergola are more favorable in areas where sunlight stays for long and is sharper. Metal roofs have a wide range of metals that can be used according to need and budget. Metal roofs with protective paint layers become more durable and long lasting. Metal roofs are easy to shape and install.

Attach The Horizontal Closure Strips

Building a Large Garage 9: Metal Porch Roof, and the Hardest Cut of Steel

The first step is to attach the horizontal closure strips to the top of the pergola.

For this, youll need wood screws. They work best if they have washers on them to prevent them from pulling right through the plastic closure strips.

Line the end of one of the horizontal closure strips up with the edge of your pergola. Make sure that it is running straight along the beam.

Screw it onto the beam in the low sections of the closure strip.

When you get to the end of the first strip, attach the next strip and continue screwing it on to the beam until you get to the end of your pergola frame.

Once the first row is complete, cut off any extra closure strip with tin snips.

Then move on to the next row. Ideally, it should be 2 feet over from the first strip, but it can be up to 3 feet away.

The important thing is to make sure that youve got the hills and valleys lined up straight across from each other. Otherwise, youll have trouble getting the corrugated roofing to lay flat like its supposed to.

Continue adding horizontal closure strips until you get all the way across the top of your pergola.

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.

Is The Polycarbonate Roofing Expensive

Its not the cheapest project, but its worth it!!

Hopefully I answered all your questions on installing and the upkeep of the polycarbonate roofing panels! If you have any more questions just let me know.

I love that we can keep all this furniture and cushions out year round, and its given us an additional place to escape to.

You can see here how much light it gets in, and how even after two years of not cleaning it it is still crystal clear! We love it and hopefully if you decide to do it you will too!

If you are wondering how we did the rest of this space including our lifted pergola check out the posts below!

What Do You Think Of Aluminum Or Tin For Awning Roofs

In the 1980s, both of these were popular options because they cost less per square foot than stainless steel. I saw a lot of gazebos and picnic shelters with this type of metal roof. However, in the last 30 years the production cost of steel has fallen to the point that they are now more cost efficient than aluminum or tin. If you have an existing awning with either of these metals, you dont need to replace it. That being said, I would not consider starting a new project with any metal other than steel.

How Do You Cover An Existing Pergola

Tin Roof Patio Metal Roof Patio Cover, metal roof patio ...

Tarp. If you need the pergola to be covered only temporarily or the other options are too cost-prohibitive another option is to cover the area with a tarp. Hook rubber tie downs or fabric straps to the corners of the tarp, and then secure the other end to a horizontal or vertical beam on the pergola.

Why Get A Pergola Roof

Your pergola might not be well-equipped to handle every kind of weather.

A lot of them dont come with any kind of shades or covers.

This means that rain will go through them rather easily and youre going to end up with a drenched patio. Snow will be just as annoying during the winter, assuming you like spending time in your backyard on colder days.

Covering your pergola with some kind of roofing material can do wonders for your patio.

It will allow you to enjoy a good cup of coffee in the morning, even if its raining heavily. Most people opt for pergola roofs because of rain, but some people might want to keep out the pesky sun as well. Too much sunlight might annoy you during the summer months.

Getting A Building Permit For A Patio Cover

Some people said a building permit was unnecessary, while others said it was impossible to get without a contractor’s license, or that it would raise my property tax, etc. So I called the permit and licensing office and got the correct answers.

  • Yes, a permit was required.
  • No, it wouldn’t raise my taxes,
  • As long as the property owner didn’t care if I wasn’t a licensed contractor, they didn’t either.

Getting the building permit was actually much easier than I thought. I took the plans to the towns permit and licensing office, filled out some paperwork, and the next morning I got a call and went back to the permit office to pick up and pay for the permit, which came to $85. They made a couple of alterations to the plan that not only were easy to accommodate but also made the project easier and cheaper! To prepare for the final inspection, I took pictures of each critical step to show the building inspector, which made the final inspection a snap.

Fiberglas And Plastic Roofing

This is the easiest roofing material to install and the most popular among homeowners. These roofing materials are typically lightweight and are cost-effective they are also very easy to cut and fit. They allow more light to come in while still protecting you from harmful UV rays.

Fiberglass and Plastic can be put on a pergola in just a few hours by using basic hand tools, a circular saw, and a nail gun.

Fiberglass can be a bit difficult to find than plastic but they are a very eco-friendly option. Most fiberglass is made from recycled materials and helps lessen the waste and pollution on our planet.
