Ondura Roofing Basics: Understand Ondura’s lightweight, durable material and its benefits for roofing applications
Ondura roofing stands out in the market due to its lightweight yet durable composition, making it an ideal choice for both DIY enthusiasts and professional contractors. Unlike traditional roofing materials like asphalt shingles or metal, Ondura is made from a corrugated asphalt-saturated fiberglass core, which is then coated with a durable, weather-resistant finish. This unique construction results in a material that weighs significantly less than alternatives, reducing the structural load on your home while maintaining robust protection against the elements. For instance, a single sheet of Ondura can weigh as little as 2.5 pounds per square foot, compared to 3.5 to 4 pounds for standard asphalt shingles.
One of the key benefits of Ondura roofing is its ease of installation, particularly when paired with nailing strips. Nailing strips are pre-cut wooden or composite boards that run horizontally along the roof, providing a solid base for securing the Ondura panels. These strips are essential because Ondura’s lightweight nature requires precise fastening to ensure longevity and resistance to wind uplift. To install, measure and mark the roof’s surface to ensure even spacing between strips, typically 24 inches on center. Use galvanized roofing nails to attach the strips to the roof deck, ensuring they are level and securely fastened. This step not only simplifies the installation process but also enhances the overall stability of the roofing system.
Ondura’s durability is another standout feature, offering resistance to cracking, rotting, and corrosion. Its corrugated design provides added strength, allowing it to withstand heavy rain, snow, and even hail. The material’s UV-resistant coating prevents fading and degradation from prolonged sun exposure, making it suitable for a wide range of climates. For example, Ondura roofing has been tested to withstand wind speeds of up to 120 mph when properly installed, a critical advantage in storm-prone areas. Additionally, its non-porous surface inhibits the growth of moss and algae, reducing maintenance requirements over time.
When considering Ondura roofing, it’s important to weigh its benefits against specific project needs. While its lightweight nature simplifies handling and reduces labor costs, it may not be suitable for extremely steep roofs or areas with stringent building codes. However, for sheds, garages, or residential roofs with moderate slopes, Ondura offers a cost-effective and efficient solution. Pairing it with nailing strips ensures a secure installation, maximizing its performance and lifespan. By understanding these basics, homeowners and contractors can make informed decisions, leveraging Ondura’s unique properties to achieve durable, long-lasting roofing results.

Nailing Strips Purpose: Learn how nailing strips provide a secure base for attaching Ondura panels
Nailing strips are the unsung heroes of Ondura roofing installations, serving as the critical foundation that ensures panels remain securely attached to the roof structure. These strips, typically made of wood or metal, are fastened horizontally across the roof’s rafters or trusses, creating a stable surface for attaching Ondura panels. Without them, nails would directly penetrate the roofing material, increasing the risk of leaks and reducing the system’s longevity. By distributing the load and providing a consistent nailing surface, these strips enhance both the structural integrity and weather resistance of the roof.
Consider the analogy of building a house: just as a solid foundation prevents the structure from shifting, nailing strips prevent Ondura panels from lifting or detaching during high winds or heavy rain. For optimal performance, strips should be spaced 24 inches apart on center, aligning with the panel’s corrugations. This spacing ensures even weight distribution and minimizes the risk of panels sagging between supports. Use corrosion-resistant nails or screws to secure the strips, as this prevents rust and maintains a tight bond over time.
A common mistake is underestimating the importance of strip alignment. Misaligned strips can lead to uneven panel placement, creating gaps where water can infiltrate. To avoid this, use a chalk line to mark the rafter locations before installing the strips. Additionally, ensure the strips are level and flush with the roof’s surface to provide a uniform base. For roofs with a pitch greater than 3:12, consider adding extra strips for added stability, as steeper slopes increase the stress on the panels.
While wood strips are cost-effective and widely used, metal strips offer superior durability, especially in humid or coastal environments. Metal strips resist warping and decay, making them a worthwhile investment for long-term performance. Regardless of material, always pre-drill holes to prevent splitting or weakening the strips. By prioritizing precision and quality materials, nailing strips transform from a simple component into a cornerstone of a reliable Ondura roofing system.

Tools Required: Gather essential tools like drills, nails, and measuring tape for installation
Installing Ondura roofing is a task that demands precision and the right tools. Before you begin, ensure you have a drill with a metal-cutting bit for creating pilot holes, as Ondura’s lightweight material can crack if nailed directly without pre-drilling. Opt for a cordless drill with adjustable torque settings to avoid overdriving screws. Pair this with 1½-inch roofing screws or ring-shank nails, specifically designed for Ondura, to secure the panels firmly without damaging the material. A 25-foot measuring tape is indispensable for marking cut lines and ensuring panels align correctly, especially when working with uneven roof surfaces.
While the drill and nails are obvious choices, a utility knife with extra blades is often overlooked but critical. Ondura’s corrugated design requires precise trimming around edges, vents, and ridges. A sharp blade ensures clean cuts without fraying the material. Additionally, a chalk line helps maintain straight rows by snapping guidelines along the roof’s length. For safety and efficiency, invest in a magnetic wristband to keep screws and nails within reach, reducing the risk of dropping hardware from heights.
Consider the roofing nailer as a time-saving alternative to manual nailing, though it’s not mandatory. This tool drives nails at a consistent depth and angle, ideal for larger projects. However, it’s essential to use the correct nail type—ring-shank nails provide better grip than smooth shank nails in Ondura’s ribbed surface. For smaller installations, a hammer paired with a nail punch ensures nails are driven flush without damaging the panel’s ridges.
Lastly, don’t underestimate the value of a level and straightedge. These tools verify the roof’s slope and panel alignment, preventing water pooling or gaps. A staple gun with ½-inch staples can temporarily hold underlayment in place before securing Ondura, though staples should never replace screws or nails for the final installation. By gathering these tools beforehand, you streamline the process, reduce errors, and ensure a durable, weather-resistant roof.
In summary, the right tools transform Ondura installation from a daunting task into a manageable project. From the drill’s precision to the utility knife’s sharpness, each tool plays a unique role in achieving a professional finish. Prioritize quality over quantity—investing in durable, task-specific tools pays off in longevity and ease of installation.

Installation Steps: Follow step-by-step instructions for installing Ondura panels on nailing strips
Installing Ondura panels on nailing strips requires precision and attention to detail to ensure a durable, weather-resistant roof. Begin by preparing the roof surface, ensuring it’s clean, dry, and free of debris. Nailing strips, typically made of wood or metal, serve as the foundation for securing the panels. Position these strips perpendicular to the roof’s slope, spaced according to the manufacturer’s guidelines—usually 24 inches on center for Ondura panels. This spacing ensures proper support and allows for thermal expansion without warping.
Next, start installing the Ondura panels at the bottom edge of the roof, working upward. Align the first panel with the nailing strip and secure it using corrosion-resistant screws or ring-shank nails. Place fasteners every 12 to 16 inches along the strip, ensuring they penetrate the underlying structure for maximum hold. Overlap subsequent panels by at least 6 inches to create a watertight seal, and use Ondura’s proprietary ridge caps or closures to finish the roof’s peak. This step-by-step approach minimizes gaps and ensures a cohesive, professional finish.
One critical aspect of this installation is managing the panels’ flexibility. Ondura is lightweight and easy to cut, but it requires careful handling to avoid cracking or bending. When cutting panels to fit around obstructions like chimneys or vents, use a fine-toothed blade to achieve clean edges. Additionally, pre-drill holes for fasteners in colder temperatures to prevent material stress. These precautions preserve the panels’ integrity and extend the roof’s lifespan.
Finally, inspect the installation for any loose fasteners or misaligned panels before considering the job complete. Pay special attention to areas prone to water pooling, such as valleys or low spots, and ensure all overlaps are securely fastened. A thorough final check not only guarantees performance but also saves time and resources by addressing issues before they escalate. With these steps, Ondura panels on nailing strips provide a cost-effective, long-lasting roofing solution.
