Answers for “Class 3 vs. Class 4 shingles”

Both are excellent when installed right; they solve different problems.

Architectural shingles (like GAF Timberline HDZ) cost roughly half as much installed, look right on most Middle Tennessee homes, install in a day, and carry outstanding warranties. For most homeowners, they're the sweet spot.

Standing-seam metal costs significantly more up front but lasts 40–60 years, sheds storms beautifully, and can lower cooling bills. It makes the most sense if this is your forever home, or on farmhouse/modern styles where the look is the point.

We install both, so you'll get a straight comparison for your specific house instead of a pitch for whatever we happen to sell.
