Roof Flashing Systems

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 rubber boot onto a flat platform and diverting water around it.

The Product

Five parts, one job. Sealing a hole in your roof properly.

01 / Platform

Raised Flat Surface

Lifts the rubber boot above the corrugations

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

Two ways roofers do it now. Both cost you.

Every pipe, vent and flue gets sealed one of two ways today. One buries your roofline under metal and your day in labour. The other perishes in the sun and leaks. Neither is the answer.

DRYPANS

METHOD 01 Cost on labour

Drypans

Slow. Costly. An eyesore.

A long metal tray runs from ridge to penetration
Hours of extra labour on every job
Big, ugly strips down the face of the roof
Roofers avoid them wherever they can

Roofers burn hours on every install

RUBBER BOOT

METHOD 02 Cost on warranty

Rubber Boot

Perishes. Pools water. Leaks.

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

Roofers eat the warranty callbacks

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 rubber boot 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.

Material

UV-stable polymer

Compatibility

Corrugated & Orb

FIG 03 · Installed

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 rubber boot 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]

on platform

Mount. Move on.

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