How to Get It
Product Overview
Protection Made Simple
Owens Corning created the Total Protection Roofing System to make it simple to get everything you need in one complete system.
Total Protection Simplified
The Total Protection Roofing System gives assurance that all the roofing components are working together to help increase the performance of the roof–and enhance the comfort for those who live beneath it.
SEAL. Roofing Components
Powerful two-part protection helps keep moisture away from the roof deck by creating a barrier against ice and water infiltration.
A Waterproof Barrier for Vulnerable Areas
Helps protect the roof where water has a tendency to collect or flow, including valleys, eaves, chimneys and skylights.
Exceeds Adhesion Performance Requirements
Helps prevent damage associated with shingle blow-off, wind-driven rain and ice damming.
The New Standard for Deck Protection
Provides a water shedding barrier under shingles as the last line of defense for the roof.
Strong, Durable and Repels Water
ProArmor Synthetic Roof Underlayment helps guard against damage from wind-driven rain.
Creates A Waterproof Barrier
Helps prevent damage associated with shingle blow-off, wind-driven rain and ice damming.
Create a Last Line of Defense
Create a water shedding barrier under shingles with the protection of synthetic underlayment.
Helps Protect Against Nature’s Elements
Starter shingles ensure a straight edge and effective seal along the eaves and rake–areas that are vulnerable to high winds.
Protection to Vulnerable Areas
Add style and extra protection with starter and hip and ridge shingles designed to match.
Balanced Ventilation
Install proper roof and attic ventilation to create balance throughout the home.
Optimize Performance
Optimize value, comfort and performance by adding attic insulation.
WeatherLock Flex Self-Sealing Ice and Water Barrier provides excellent protection against water infiltration resulting from freeze/thaw cycles wind driven rains and normal water flow around eaves, valleys, vents, chimneys and skylights. Plus it can be applied over existing poly surface ice and water barriers so re-roofing is easy and less costly. For optimal protection, apply to entire roof deck on 2:12 to 4:12 pitch roofs. Ensure proper ventilation is met when applied over the entire roof deck.

Absolutely great stuff. I have it on the outside roof exposed to weather and sunlight and it is great going into the third winter . . . and I use it under carpet instead of vinyl and I can put it down cheaply.

Product is very good once down.
Unfortunately product was difficult to lay by not being able to lay half at a time like other brands.
and paper backing sometimes stuck to ice shield.
I would choose a different brand next time only because of this.

Do not know how well it works but putting down is next to impossible. Paper on the backside tears and it is just so sticky. Can't do it by yourself. I have use other s ice seal worked well and I could put it down by myself. Will never use again. It may be great stuff but to labor intense.
