Deck Blocks

The grooves in a standard deck block are typically around 1.5 inches wide and 1.5 inches deep, designed to securely hold a 2×4 or 2×6 joist, depending on the specific deck block design; the post-receiving hole in the center of the block is usually sized to fit a 4×4 post. 

Key points about deck block grooves:

  • Size variation:Dimensions can slightly differ based on the manufacturer and model of the deck block. 
  • Function:The grooves allow for horizontal attachment of the deck joists to the concrete block. 
  • Post support:Most deck blocks also have a central hole designed to securely hold a vertical deck post, usually a 4×4.

Roof Over Chicken Run

To ensure the peak of your plexiglass-covered chicken run is watertight, here are a few good options:

1. Use a Ridge Cap

A polycarbonate or metal ridge cap is the best option for sealing the peak. These are designed to bridge the gap between sloped panels and prevent leaks. You can find them in clear or tinted polycarbonate to match your plexiglass.

  • Overlap the ridge cap onto both sides of the plexiglass panels.
  • Use butyl tape or silicone sealant along the edges where the ridge cap meets the panels.
  • Secure it with screws, using rubber washer roofing screws to prevent leaks.

2. Overlapping the Plexiglass Panels

If a ridge cap isn’t an option, you can slightly overlap the plexiglass sheets at the peak:

  • Cut the top edges of the panels at an angle to meet snugly.
  • Allow for a 2–3″ overlap between panels.
  • Apply clear silicone sealant between the overlapping edges.
  • Secure with polycarbonate fasteners to avoid cracking.

3. H-Channel or U-Channel Connectors

For a cleaner look, you can use H-channel or U-channel connectors (typically made of polycarbonate or aluminum) to bridge the gap. These:

  • Provide structural support.
  • Prevent water seepage when used with silicone sealant inside the channel.
  • Allow for slight movement due to temperature changes.

4. Flashing with Waterproof Tape

If you’re using a wooden ridge beam under the peak, you can:

Use EPDM or butyl waterproof tape along the joints for extra sealing.

Attach flashing (aluminum or polycarbonate) over the peak.
