on a roof
25 years of watching the same seals fail.
Shawn Ashford has been a qualified roof plumber for 25 years. He’s run forensic leak detection for insurance companies, walked thousands of roofs, and watched the same penetration seals fail in the same ways — perished rubber, pooled water, silicone that never stood a chance. The Penenator is what he built to fix it.
Every leak callout he ever attended started at a penetration. So instead of patching the symptom one more time, he re-engineered the whole flashing — lifting the seal onto a raised flat platform and diverting water around it, not into it.
Designed in Toowoomba. Manufactured by Forma3D in Tweed Heads using Modplas materials. Currently undergoing Australian Standards testing in Melbourne, with a patent application filed. Built for Australian roofs, by an Australian roofer.
"Penetration seals are the main source of leaks I find. So I built the thing that fixes it."
