How Many Screws Per Ondura Panel?
Roofs have one of the most important jobs in your entire home. The roof is designed to keep the entire house together by protecting everything underneath it. Roofs come in many shapes and sizes, but they must possess durability and strength.
Because of this, many roofing materials are available in the market, promising durability for many years. One of the most popular brands when it comes to roofing is Onduline, which makes the Ondura line of lightweight roof panels. They are made from premium corrugated asphalt for complete weather protection.
These roofing panels are easy to install and can be installed over most existing roofs. To do this, you'll need a properly calculated number of roof panels and genuine Ondura hex screws to fasten the panels on the roof.
Types of Ondura panels and required screws
Ondura has various types of roofing panels that are available. They have different corrugations to choose from, so the number of screws necessary to fasten them varies.
For the Ondura 6V roofing panels, there are 6 corrugations on the panel. To install them, a minimum of 15 screw fasteners should be used on the panels. The fasteners should be installed in three rows, with five screws per row. When overlapping them with another panel, add one screw each per row.
When using the Ondura 9V roofing panels, there will be 9 corrugations on the panel. The Ondura 9V roofing panel requires at least 17 screws to fasten a panel. An overlapping panel should have about 29 screws maximum on the panel.
The Ondura 10V premium roofing panels will have 10 corrugations. There must be 19 screw fasteners per panel upon installation. When the overlapping panel is installed, 13 additional screws are needed to fasten the overlap panel properly.
For Ondura 10V half panels, 20 to 26 screw fasteners are required. The number of screw fasteners depends on the overlap of the adjacent panels.
Screw the panels perpendicularly to the roof and through the crown of the corrugation. Do not overdrive or underdrive the screw because it can cause the panels to become loose. Always check the rubber washer on the roofing screw, which should be in contact snugly with the roofing sheet.
All Ondura roofing panels must be installed properly to avoid any issues in the future. Improper installation and fastening of the panels will cause waterproofing issues and may ruin the roofing panel prematurely.
How Much Should Ondura Panels Overlap?
Corrugated roofing panels are meant to overlap because it creates a seal and prevents water from seeping through the panel's edges. Overlapping them covers up the edges of the panel, turning them into one solid and seamless roof. Securing the panels makes the roof panels less prone to leaking and also prevents the panels from getting blown off.
Like most corrugated roofs, the Ondura panels should overlap at least 6 or 7 inches over the first set of panels. Make sure to fasten this overlap panel securely to the previous roofing panel to create a seal. Remember to fasten them with at least one roofing screw for every row.
To make it simple, the Ondura panels must overlap by at least one corrugation against the eave of the first panel. This spacing is enough for you to drive fasteners over the overlapped parts of the panel.
How Long Will Ondura Panels Last?
One of the best advantages of Ondura panels is their durability. These roofing panels are made from high-quality organic fiber core. This core is then impregnated with asphalt, which makes them highly durable and weather-resistant.
Since these roofing panels are infused with asphalt, they imbibe all the qualities of bitumen, like impermeability, flexibility, and resistance to heat and rain. According to the manufacturers, the Ondura roofing panels can last up to 40 years or more if they are installed correctly.
Of course, varying conditions can make some Ondura panels weaker. If exposed to extreme heat or freezing temperatures, some Ondura panels may break. Always check to see if these asphalt roofing panels will work well in your area before installing them on your roofs.
Can I Walk On Ondura Panels?
Just like other roofing panels, you can also walk on Ondura panels. However, since they are more flexible than other panels, there are special precautions necessary when walking on Ondura panels.
When walking on Ondura panels, remember to wear soft-soled shoes to avoid breaking the panels. Place your feet perpendicular to the corrugations and walk along this line. Distribute your weight as you walk across the roofing panels. Do not walk against the corrugations because a person's weight can break the panel in half.
Always remember to walk only on areas that have structural support. Check the areas where there is heating or purlins because these structural supports will be able to handle your weight.
The Ondura panels can be slippery when it is wet, oily, dusty, or frosty. If these conditions exist on the roofing panels, avoid walking on them. Do not walk on the panels when it is windy, as it can be dangerous to be in a high location without proper safety precautions. High heat can also be dangerous on asphalt panels, so don't walk on the panels when the sun is very hot.
