Weather-Tite™ Technology: a Technology Worth Patenting!

What is Weather-Tite technology?

Weather-Tite™ technology is a patented roofing shingle technology featuring two sealant bands. It offers many safety and economic benefits, while ensuring your roof will stand up to whatever Mother Nature throws its way.

How are Weather-Tite shingles different?

All of BP Canada’s architectural shingles, as well as the classic shingles produced in the LaSalle, Québec, plant, now feature Weather-Tite™ technology.
The patented dual sealant band is what sets these shingles apart from the competition. While the continuous band ensures maximum adhesion, the discontinuous (“dotted”) band increases the shingle’s adhesion, keeping wind-driven rain where it should be: flowing off your roof.

Does Such a Simple Innovation Really Make a Difference?

Yes! As simple as it may sound, BP Canada’s Weather-Tite™ technology offers many real-life, noticeable advantages, including:

Safety and reliability

Proven over years of use, this patented technology makes shingles reliably tough even when subjected to the worst weather. The result? A roof you can trust. What’s more, the Weather-Tite™ technology is at the core of BP’s high-wind warranty, which covers winds up to 220 km/h*. Simply put, this is the best high-wind warranty in North America!

A flawless look

The most notable advantage of Weather-Tite™ technology is the additional adhesion provided by its second sealant band. This makes for an optimal installation which  translates into improved long-term performance thanks to shingles that will stay in place – for a flawless appearance year after year.

A roof that stands up to rain

Even if wind-driven rain gets under the shingles’ discontinuous band, no water will get past the continuous Weather-Tite band. In other words, water infiltration (and thus roof leakage) is NOT something you will worry about with Weather-Tite™ technology standing guard!
