The thickness of the sheets, which can vary, affects their tolerance and weight, and should be chosen based on the specific structural requirements of the roofing project.

Durability is another critical factor, with the sheets' ability to withstand different temperatures and environmental conditions being paramount. A high glass transition temperature (Tg) of around 80°C indicates the sheet's capacity to maintain structural integrity under heat. Additionally, the sheets should have a balanced laminate structure to ensure stability and flatness.

The manufacturing process also plays a role in the selection criteria. Sheets should be cured under controlled pressure and temperature to achieve the desired mechanical strength. For roofing applications where aesthetics are a concern, the finish on one side of the sheet should be considered, ensuring it meets the visual requirements of the project.

Lastly, the potential for customization should be assessed. While some manufacturers may not offer custom fabrication for small quantities, it's important to know the range of sizes available to ensure they meet the project's needs without excessive waste or additional cutting.

Selecting FRP sheets that are tailored to withstand specific environmental challenges is crucial for maximizing their lifespan and ensuring the durability of the roofing system.

For those considering fiber sheets for roofing applications, understanding the installation process is crucial. These sheets are known for their ease of installation with common tools and can be drilled, sawed, punched, or nailed without damage. When installing, it's important to start at the leeward side of the roof to protect against wind and weather. Overlapping is essential for preventing leaks; a minimum of one corrugation overlap at sides and an 8-inch end-lap for low-pitched roofs is recommended. Fastening should be done through the crowns at every second corrugation, using fasteners with Neoprene washers to ensure a tight seal. During installation, pre-drill holes slightly larger than the fastener diameter to accommodate expansion and contraction, which is particularly important for fiberglass-reinforced panels. To maintain the integrity of the sheets, avoid walking on them and ensure that screws are tightened just enough to prevent washer rotation, followed by an additional turn. By adhering to these application techniques, fiber sheets can provide a durable and effective roofing solution.

For optimal installation of corrugated fiber sheets, it's crucial to follow best practices that ensure stability and longevity. Begin by pre-drilling holes in the panels, which should be larger than the fastener diameter—1/16" for fiberglass and 1/8" for PVC and Polycarbonate—to accommodate expansion and contraction. Install panels starting from the leeward side, progressing to the windward end, to protect against wind and weather. Overlap corrugations by at least one ridge and use an 8" end-lap for low-pitched roofs, reducing to 6" for steeper slopes. Secure the panels by fastening through the crowns at every second corrugation, with fasteners spaced 6" to 8" apart at the ends and 12" to 16" on intermediate supports. Use fasteners with Neoprene washers to prevent leaks, tightening just enough to prevent washer rotation plus an additional turn. To maintain the integrity of the seal, avoid over-tightening, which can cause deflection and damage to the panels. Lastly, ensure that all tools and fasteners are compatible with the material of the fiber sheets to prevent corrosion or damage.

Maintaining a fibre cement roof is crucial for ensuring its longevity and performance. Regular cleaning is essential; remove debris, leaves, and other materials that can accumulate and cause blockages in gutters or seams. Address any damage such as cracks or punctures promptly with appropriate sealants to prevent water ingress. It's also important to inspect the roof regularly for signs of wear, such as loose shingles or missing nails, especially around flashing areas, to avoid moisture buildup and corrosion.

Trees and shrubs near the roof should be kept trimmed to prevent branches from scratching or chipping the roofing material. If heavy items need to be stored on the roof, distribute the weight evenly to avoid damage. Walking on the roof should be avoided as fibre cement sheets can be brittle; if necessary, use a board to distribute your weight.
