Steep slope systems — pitches of 3:12 and greater — shed water by gravity, which makes the visible material only half the story. Underlayment, ice barriers, flashing, and ventilation are what actually determine service life. It’s why two identical-looking shingle roofs can differ by decades.
As a GAF Master Elite® certified contractor, Miller installs architectural and designer shingles with the full manufacturer system — and qualifies homeowners and building owners for enhanced warranties up to 25 years. For distinctive buildings we also install synthetic slate and shake that deliver historic character at a fraction of the weight.
