Certainteed landmark after 10 years

[roof_lover]

I was an installer for this product for close to 20 years.
I still have good things to say
That is i never had one fail.
And even seen roofs where every nail was installed incorrectly and it didnt leak.
But i still need to present this evidence.
Where there is just little algae resistence
And the cap shingles have unsealed but not failed.

Site wont let me post a 50 second video.

Not a single failure, even on roofs with nail mishaps—it’s impressive. Sometimes, though, you might need to provide evidence, especially for minor issues like algae resistance or unsealed cap shingles.
