Architectural shingles are thicker (2-3 layers vs 1), last longer (30 vs 20 years), handle wind better (110-130 mph vs 60-70 mph), and look more dimensional. The extra $150-200 per square is worth it for the added durability and curb appeal. 3-tab shingles are becoming obsolete except for budget rentals.

Building code allows up to 2 layers in most areas, saving $1-3/sq ft in tear-off costs. However, this voids most manufacturer warranties, hides deck problems, adds weight, and shortens the new roof’s life. Only consider for budget rentals where you own the property short-term. Quality contractors often refuse overlay work.

Despite “30-year” or “lifetime” marketing, expect: 3-tab (15-20 years), Architectural (20-30 years), Premium (25-40 years). Actual lifespan depends on installation quality, attic ventilation, climate, and maintenance. In harsh climates, reduce expectations by 20-30%.

Basic architectural shingles hit the sweet spot for rentals. The upgrade from 3-tab costs about $1,500 extra but lasts 10+ years longer, reducing long-term costs. Skip premium features like impact resistance unless you’re in severe hail areas with insurance discounts.

Manufacturer material warranties are prorated and rarely pay out fully. More important: contractor workmanship warranty (5-10 years) and wind rating certification. If available, system warranties (like GAF Golden Pledge) combining materials and labor are worth the extra cost for primary residences.

Look for: missing/cracked shingles, granules in gutters, daylight through roof boards, age over 20 years, or sagging areas. One major leak often costs more to repair interior damage than proactive replacement. For rentals, replace before problems to avoid tenant issues.

Yes, black shingles can increase attic temperatures by 20-40°F, raising cooling costs 10-15% in hot climates. However, proper attic ventilation and insulation matter more than color. In cold climates, dark shingles actually save money through faster snow melt.
