What's the biggest factor in roofing cost?
Material and roof size dominate, but pitch and stories matter a lot: a steep or multi-story roof is slower and riskier to work on, so labor climbs. Tear-off of multiple old layers and hidden decking damage are the most common budget surprises.
Is a metal roof worth the extra cost?
Metal costs roughly 2–3× asphalt up front but lasts 40–70 years vs 15–25 for asphalt, and can lower cooling bills. It's often worth it if you plan to stay long-term; for a short hold, architectural shingles usually offer the best value.
