Rochester's Trusted Roofing Experts
From emergency repairs to full roof replacements, MJ Exterior delivers durable, weather-tight roofing solutions built to handle Rochester's toughest winters. Licensed, insured, and locally owned.
What We Offer
From a single shingle repair to a full commercial re-roof, we handle every roofing need with the same attention to detail and commitment to quality.
Roof Installation
New construction or full replacement — we install asphalt shingles, metal roofing, and flat roofing systems with precision, proper underlayment, and code-compliant flashing.
Roof Repair
Leaks, missing shingles, storm damage, and failing flashing repaired fast before small problems become costly interior damage. We diagnose the root cause, not just the symptom.
Full Roof Replacement
Complete tear-off and replacement of aging or failing roofs, including new ice-and-water shield, synthetic underlayment, ridge venting, and drip edge for long-term performance.
Metal Roofing
Standing seam and corrugated metal roofing that lasts 50+ years. Superior snow-shedding, energy efficiency, and a modern aesthetic that adds serious curb appeal.
Flat & Low-Slope Roofing
TPO, EPDM, and modified bitumen systems for flat and low-slope roofs on homes, garages, and commercial buildings — properly detailed for Rochester's heavy snow loads.
Gutter Installation
Seamless aluminum gutters fabricated on-site and installed with proper pitch and hanger spacing to move water away from your foundation efficiently.
Gutter Guards & Repair
Micro-mesh gutter guards that keep debris out year-round, plus repair of sagging, leaking, or improperly pitched gutters that are causing water problems.
Storm Damage & Insurance
Hail and wind damage assessed, documented, and repaired. We work directly with insurance adjusters and provide detailed reports to support your claim.

Architectural Shingles
Architectural (dimensional) shingles are the most popular residential roofing material in the U.S. Unlike old 3-tab shingles, architectural shingles are laminated from two layers of fiberglass-reinforced asphalt, giving them a thicker, textured profile that mimics the look of wood shake or slate. They're manufactured by GAF, Owens Corning, and CertainTeed with 30–50 year limited warranties and wind resistance ratings up to 130 mph. For most Rochester homes, architectural shingles offer the best balance of performance, aesthetics, and value.
Key Benefits
- 30–50 year limited manufacturer warranties
- Wind resistance ratings up to 130 mph
- Thicker laminated construction resists cracking and impact better than 3-tab
- Available in dozens of colors and profiles to match any home style
- Best value for most residential applications
- Qualifies for enhanced warranty coverage with certified installers
