A roof replacement is the full tear-off of old roofing down to the deck, followed by new underlayment, flashing, ventilation parts and shingles installed as one system.
Whether your roof is showing its age or was recently damaged by a Missouri hailstorm, this complete guide covers everything St. Louis homeowners need to know before replacing their roof.
How Do I Know It's Time for a New Roof?
Most roofs in the St. Louis area last 20–30 years depending on material quality, installation, and our unpredictable Missouri weather. The combination of scorching summers, ice dams in winter, and severe spring hailstorms puts your roof through a brutal cycle every year. Here are the clearest signs it's time to call a professional:
- Shingles are curling, buckling, or missing entirely
- Your attic has visible daylight coming through the roof boards
- Granule loss is filling your gutters (a sign the shingles are aging out)
- Dark streaks or moss growth across the surface
- Interior water stains on ceilings or walls after rainfall
- The roof is approaching or past 20 years old
- Recent hail or high-wind storm damage (even if you can't see it from the ground)
Roofing Material Options for St. Louis Homes
Choosing the right material for your St. Louis home means balancing durability, aesthetics, budget, and local climate performance. Here's a breakdown of the most common options:
Architectural Asphalt Shingles (Most Popular)
Architectural (also called dimensional or laminated) shingles are the most widely installed roofing product in Missouri for good reason. They offer excellent value, a long lifespan of 25–30+ years, and come in dozens of colors and styles. We strongly recommend CertainTeed's Landmark® series for most residential projects — it's one of the best-tested architectural shingles on the market with outstanding wind resistance ratings up to 130 mph.
- Cost: $8,000–$18,000 for a typical St. Louis home
- Lifespan: 25–35 years with proper installation
- Best for: Most residential homes across St. Louis, Chesterfield, and St. Charles
Impact-Resistant Shingles
Given how frequently St. Louis gets hit with damaging hailstorms, Class 4 impact-resistant shingles have become increasingly popular — and often qualify for homeowner's insurance discounts. CertainTeed's Northgate® shingle is a Class 4 rated product we frequently install for clients who want maximum hail protection.
- Cost: 10–15% premium over standard architectural shingles
- Insurance savings: Many insurers offer 10–30% premium discounts
- Best for: Homes in hail-prone areas of Jefferson, St. Charles, and St. Louis counties
Premium Shake & Slate-Look Shingles
For homeowners seeking a high-end aesthetic without the maintenance of real wood shake or natural slate, CertainTeed's Presidential Shake® and Grand Manor® shingles deliver stunning curb appeal with superior longevity.
- Cost: $15,000–$35,000+ depending on roof size and complexity
- Lifespan: 40–50 years
- Best for: Upscale homes in Ladue, Town and Country, Wildwood, and Sunset Hills
The Roof Replacement Process: Step by Step
When you hire STLBRC for your roof replacement, here's exactly what happens from first call to finished project:
- Free Roof Inspection — We come to your home, inspect the roof from all angles, assess decking condition, check ventilation, and photograph any damage.
- Detailed Written Estimate — You receive a line-item proposal covering materials, labor, disposal, permits (if required), and timeline.
- Material Selection — We help you choose the right CertainTeed shingle line, color, and warranty tier for your home and budget.
- Tear-Off & Decking Inspection — We strip the old roofing down to the deck and inspect for rot, soft spots, or structural issues before installing anything new.
- Leak Barrier Installation — We install CertainTeed WinterGuard™ ice and water barrier along eaves, valleys, and penetrations — critical in Missouri where ice dams form.
- Underlayment — Synthetic underlayment goes over the rest of the deck for a secondary water barrier.
- Shingle Installation — Field shingles are nailed to manufacturer specifications. Hips, ridges, and valleys are meticulously flashed and capped.
- Clean-Up & Final Walk-Through — We use magnetic rollers for nails, haul away all debris, and do a full site inspection with you before we leave.
- Warranty Registration — We register your CertainTeed SureStart PLUS™ warranty so your investment is fully protected.
How Much Does Roof Replacement Cost in St. Louis?
Roofing costs vary based on your home's square footage, roof pitch, number of layers to remove, and material selected. Here are typical ranges for St. Louis area homes in 2026:
- Small home (1,000–1,500 sq ft): $7,500–$14,000
- Average home (1,500–2,500 sq ft): $12,000–$22,000
- Large home (2,500–4,000 sq ft): $20,000–$40,000+
- Premium materials (Presidential Shake, Grand Manor): Add 30–80% to base cost
- Steep pitch premium: Add 15–25% for roofs above 8/12 pitch
Understanding Your Roof Warranty
When we install a CertainTeed roofing system, you receive one of the strongest warranty packages in the industry. There are two key warranties to understand:
- Manufacturer's Warranty (CertainTeed) — Covers defects in the shingle itself. The SureStart PLUS™ warranty on Landmark® shingles provides 10-year full replacement coverage, then prorated coverage up to the shingle's rated lifetime.
- STLBRC Workmanship Lifetime Guarantee — We back our installation work for life. If anything we installed fails due to craftsmanship, we come back and fix it. Period.
- Wind Warranty — CertainTeed Landmark® shingles carry a 130 mph wind resistance warranty when installed to spec.
- Algae Resistance — StreakFighter® protection is built into most CertainTeed shingles to prevent black algae streaking.
