  • Fasteners Plus #3 High Temp Roof Boot Kit – Solid Product, My Sizing Mistake
Size Name: #3 Kit (Pipe OD 1/4" to 5-3/4") Color: Red
I ordered this Fasteners Plus #3 Roof Boot Kit intending to seal a chimney pipe on my metal roof, but I ended up returning it because it was too small for my needs. My fault—I didn’t double-check the specs closely enough. It’s designed for pipes 5-1/2" to 11-1/2" in outer diameter, and my pipe was a beefy 12", so the silicone boot wouldn’t stretch far enough. Lesson learned: measure twice, order once! Before sending it back, I got a good look at it. The kit includes a red high-temp silicone boot (500°F continuous rating), a tube of NovaFlex sealant, 30 red-painted roofing stitch screws, and a 5/16" magnetic nutsetter—everything you’d need for a proper install. The quality seemed spot-on: the silicone felt thick and flexible, the aluminum base was sturdy, and the screws had self-drilling tips. The bright red color was bold (maybe too much for my gray roof), but it matched the description perfectly. It’s USA-made, which I appreciated, and the packaging was intact. I can’t vouch for performance since I didn’t install it, but it looks built for safety—high-temp resistance means no melting or fire risks for the right setup. Compared to a basic boot I’ve used, this kit’s extras (sealant, screws) make it a better deal, though it’s pricier. My sizing flub aside, it seems like a reliable choice for smaller pipes. I’d give it 4 stars—docking one for my own mismatch, not the product. It’s as advertised, so if your pipe’s in the 5-1/2" to 11-1/2" range, this should work great. Measure carefully! ... show more
