This product requires more silicone to install than the normal range of Defender Pigeon Spikes. We recommend that you use 1 tube of silicone per 10 strips.
PLEASE NOTE : Only use the Defender Ridge Spike™ if your ridge tile is peaked (upside down V shaped). If your roof has a half round ridge tile use the Defender Wide™ Stainless Steel Spikes, there is sufficient room on the half round ridge tile to fix this spike.
These spikes are on a 33.3cm (13 inches) long base, so are 3 per linear metre.
- Squeeze pigeon spike fixing silicone generously onto the base of the spike, about the size of your finger (10mm). Ensure the silicone is applied to both the inside angles of the Defender Ridge Spike™.
- Stick the first row of ridge spikes as close as possible to the end of the ridge tiles, so the end is fully protected. Press down firmly to ensure full adhesion.
- Every effort should be made to spike the full length of the ridge tiles. Using a hacksaw, cut the Defender Ridge Spikes™ into the correct size to finish off the run.
- Try not to damage the spikes during installation as a slightly damaged ridge spike is likely to provide an ideal roosting or nesting spot for a pigeon or gull. Any damaged ridge spikes should be replaced before the birds move in.
