Roofer in St. Louis, MO

Ask for a written scope naming the shingle line, underlayment, ventilation work, and warranty coverage before any deposit changes hands. Also ask for a written scope, pricing breakdown, and the credentials or insurance documentation that apply to this trade before work starts.

In St. Louis, quotes usually move with roof pitch, tear-off scope, decking damage, material grade, and disposal costs.

Roof permits and inspections vary by city, but full replacements usually require both. Ask what the contract covers if damaged decking is uncovered.

A full roof replacement typically costs $8,000 to $25,000 for an average-sized home (1,500-2,500 sq ft). Asphalt shingles are the most affordable ($4-$8 per sq ft installed), while metal roofing ($8-$14) and tile ($10-$20) cost more but last significantly longer. Factors include roof size, pitch, material, and removal of old roofing.

Roof lifespan depends on the material: asphalt shingles last 20-30 years, architectural shingles 30-50 years, metal roofing 40-70 years, clay or concrete tile 50-100 years, and slate 75-150 years. Climate, ventilation, maintenance, and installation quality all affect longevity.

Signs you need roof work include missing or curling shingles, granules in gutters, daylight visible through the attic, sagging sections, water stains on ceilings, and moss or algae growth. If damage covers less than 30% of the roof and the structure is sound, repair may suffice. Otherwise, full replacement is more cost-effective long-term.
