Stop patching what shouldn't have failed.

Penetration seals are the number one cause of roof leaks. The Penenator re-engineers the entire flashing — lifting the dektite onto a flat platform and diverting water around it.

02 / Diversion
V-Shape Channels
Routes water around the penetration
03 / Base
Corrugated Profile
Slides under via single slit cut
04 / Material
UV-Stable Polymer
Outlasts every silicone seal it replaces
The Problem

Three ways to seal a roof penetration. All three fail.

Every leak callout starts at a penetration. The pipe, the vent, the antenna — wherever something pokes through the roof, something is also failing. Here's why none of it lasts.

DRYPANS · PLACEHOLDER
METHOD 01 Cost on margin

Drypans

Ugly. Slow. Still leaks.

  • Take significantly longer to install
  • Higher labour cost on every job
  • Condensation builds up underneath
  • Ugly metal strips down the roof
Tradies lose margin on labour

SILICONE · PLACEHOLDER
METHOD 02 Cost on callbacks

Silicone

As good as the person putting it on.

  • Lifespan of 2–3 years before it perishes
  • Quality depends entirely on the installer
  • A single pinhole causes a leak
  • Requires complete re-application
Tradies return for callbacks

DEKTITE · PLACEHOLDER
METHOD 03 Cost on warranty

Dektite

Pools water. Squashes badly.

  • Breaks down over time under UV
  • Water sits underneath the seal
  • Doesn't seal properly to orb sheets
  • Has to be squished to fit the profile
Tradies eat warranty claims

I've been a qualified roof plumber for 25 years. Penetration seals are the main source of leaks I find. So I built the thing that fixes it.

The Fix

One flashing. Three problems solved.

FIG 02 · V-Shape
FEATURE 01

Lifts the seal above the water course.

A raised flat platform sits the dektite on a clean horizontal surface above the corrugations. Water flows around the seal, not into it. No damming, no pooling, no perishing silicone trying to bridge a profile.

FEATURE 02

Diverts water laterally.

Contoured diversion surfaces channel water around the penetration rather than damming behind it. The seal sits in calm water, not a current.

FEATURE 03

Kills the drypan. For good.

Traditional installs run a metal drypan all the way from the ridge to every penetration. The Penenator's integrated base makes them obsolete. Less labour. Fewer callbacks. Better margins.

Installation

Three steps. No silicone gymnastics.

STEP 01
[REQUIRED]
Photo: slit cut +
base sliding under

Cut. Slide.

A single slit cut in the roof sheet. The Penenator's corrugated profile slides under the upper sheet and locks against the existing rib.

STEP 02
[REQUIRED]
Photo: Penenator seated,
before dektite mounted

Seat. Fix.

Base sits flush on the roof. Side flanges screw down onto the sheet. The flat platform is ready to receive the seal.

STEP 03
[REQUIRED]
Photo: dektite mounted
on platform

Mount. Move on.

Mount the dektite on the flat platform. No bending, no stretching, no silicone marathons. Onto the next one.

The Range

Four flashings. Every common penetration.

Designed in Toowoomba. Manufactured in Tweed Heads. Trade pricing available on request.

The Story

Designed by a roofer. For a problem he sees every week.

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. The Penenator is what he built to fix it.

Designed in Toowoomba. Manufactured by Forma3D in Tweed Heads. Currently undergoing Australian Standards testing. 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."
