Roofing Systems
Steep Slope Roofing
Where the roof is part of the architecture — shingles, tile, and synthetics installed with the details that decide whether a steep roof lasts.
System Overview
Steep Slope Roofing, Explained
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.

Common Questions
Straight Answers
Architectural (laminated) shingles are thicker, heavier, rated for higher wind, and carry longer warranties — for a modest price difference. They’ve effectively replaced 3-tab as the standard on quality work.
Age matters even when the surface looks good, because underlayment and flashings age too. A free inspection tells you where it really stands — sometimes the honest answer is ‘you have years left.’
