How to Install a Roofing Corrugated Fiberglass Panel

A corrugated fiberglass panel is prepared from a mat of high strength glass fibers embedded in an organic resin, creating a semi-transparent coat. This type of panel is shaped into a rolling prototype like a wave. The panels allow the filtration of light, but keep out the severity of direct sunlight. Being bendable, they make an excellent roofing material that is trouble-free to put in and can be drilled, punched, sawed and nailed without causing damage to the panel. Follow the simple steps below to effectively install your own corrugated fiberglass roofing panel.

  • Protective glasses or goggles
  • Mask
  • Barrier cream (for your safety)
  • Mechanical  or Electric Drill
  • Screw
  • Nails
  • Screw driver
  • Hammer
  • Paint
  • Paint brush

Step 1 - Post foots and Anchors

Post foots should be something like 14 inches deep and 12 inches across. Set 8x3/8-inch bolts about 3 inches deep into poured concrete for post anchors. Wood posts may also be secured with 4-inch angle brackets. Attach 2x6-inch rafter hangers to header, then attach header to house studs with lag screws.

Step 2 - Setting Crossbeams

Drill posts and set on pins. Toenail crossbeam to post. NOTE: Allow 7-feet 4 inches from floor to bottom of front header for best ventilation. 

Pre-notch rafters to compensate for slope. Allow a 1-inch minimum pitch per foot for adequate drainage. Put together rafters to header and crossbeam with 1-inch screws and nails.

Step 3 - Installation of Cross Braces

For ease of installation and an attractive design, nail cross braces between rafters using alternate spacing. Nail round and corrugated molding strips to framing, then paint or stain wood before installing panels. Put down panels on rafters with one corrugation overlap, and fasten with aluminum screw nails. Holes should be pre-drilled. Put together flashing at the same time.

Construction Notes

  1. To keep panels from defelcting, tighten screws until washers will not turn around, then tense up one more turn.
  2. Keep away from excess burrs on drilled or punched holes to look after Neoprene sealing face.
  3. Make a hole for and fasten extreme bolts with jam-packed support below all valleys. Then drill for and fasten in-between points.

Cleaning Instruction

Wash panels with either mild detergent-type cleaners or by steam and high pressure spray systems. Apply cleaners with sponge or soft brush and rinse thoroughly in cold water to eliminate cleaning agent film build-up. Test a small area before applying over the entire surface. Hard water deposits may be removed with a 10 percent solution of acetic acid in cold water. Rinse thoroughly.

Universal Information about Corrugated Panels

Panels install easily with ordinary tools and may be sawed, drilled, punched or nailed without causing any damage. The equipment is rot-proof, rust-proof and water-proof and is not harmed by ordinary cleaning solutions.
