Benefits of the CertainTeed Integrity Roof System, installed by Agassiz Roofing

A quality roofing system involves the underlayments, shingles, accessory products, and ventilation all working together. Day after day, year after year.

At Agassiz Roofing, we take pride in the work we do and providing you with the best possible solutions for your roofing project. As we know, Winnipeg has some of the harshest weather on the planet, ranging from -40 degrees Celsius in the Winter to 40 degrees Celsius in the Summer. This puts your home and especially your roof through a lot of stress.

The Integrity Roof System by CertainTeed is designed to provide optimum performance – no matter how bad weather conditions are. After all, better quality shingles mean longer-lasting roofs. Add in underlayment and accessory products and you’ve got a system that really works.

When you choose an Integrity Roof System you gain the advantage of having CertainTeed as your single manufacturing source to stand behind its roofing system components.

Lets dive into the components of the Integrity Roof System:

Hip & Ridge Accessories

Accessory shingles are used to finish the hips and ridges of the roof and are designed to complement the appearance of CertainTeed shingles. Our most commonly used hip and ridge shingles are the CertainTeed ShadowRidge used with The CertainTeed Landmark Series.

CertainTeed Ridge Vent

Ridge vents combined with sufficient intake vents are the most effective ventillation system. A proper attic ventilation system is a key component to a healthy roof.

CertainTeed Shingles

High-quality shingles available in a wide variety of styles and colors covered by the strongest warranty in the business. The most popular CertainTeed shingle used by Agassiz Roofing is the CertainTeed Landmark Series.

RoofRunner or Diamond Deck

High-performance underlayment provides a protective water-resistant layer over the roof deck and a secondary barrier against leaks. For your peace of mind! RoofRunner lightweight synthetic polymer-based underlayment outperforms felt and outclasses other synthetics. The CertainTeed DiamondDeck underlayment similar to the RoofRunner is a slight step up and provides best-in-class performance in terms of both weather protection and contractor safety.


WinterGuard waterproofing shingle underlayment is installed between the roof deck and the shingles, creating a weather-tight barrier that prevents backed-up water from getting into your home. Installed at the eave edge, in the valleys, and surrounding any penetration, WinterGuard prevents leaks from wind-driven rain and ice dams in these vulnerable areas.

Starter Shingles

Starter shingles are designed to work specifically with each different type of CertainTeed singles for maximum performance. CertainTeed SwiftStart is the most commonly used starter shingle by Agassiz Roofing as it is designed specifically for use with CertainTeed Landmark Series shingles. Agassiz Roofing uses the starter shingles along the roof eaves and rakes providing you with an upgraded 130mph wind warranty when used with the CertainTeed Landmarks.
