Four Twelve Roofing in Baltimore: Residential and Commercial Work with Transparent Pricing

Four Twelve Roofing is a licensed and insured roofing contractor serving Baltimore homeowners and commercial property managers with asphalt shingle, metal, and flat roof installation and repair. The company operates as a mid-sized local firm, handling projects across the city's mix of rowhouses, single-family homes, and small commercial buildings rather than functioning as a high-volume chain or one-person operation.

What Four Twelve Roofing Actually Does

Four Twelve specializes in roof replacement, repair, and inspection for residential properties and small commercial buildings throughout Baltimore. The company is licensed by the Maryland Home Improvement Commission and carries general liability and workers' compensation insurance. They handle material selection, structural assessment, permitting coordination, and tearoff and disposal of existing roofing. The firm does not perform roofing maintenance contracts or gutter-only work; they focus on full or partial roof projects.

Materials, Warranty, and Pricing

Four Twelve works primarily with architectural asphalt shingles (the standard for Baltimore rowhouses), standing-seam metal roofing, and TPO flat roof membranes. Asphalt shingle roofs typically cost between $8,000 and $15,000 for a 2,000-square-foot residential installation, depending on roof complexity, deck condition, and local permit fees. Metal roofing runs roughly 40 to 60 percent higher than asphalt but lasts significantly longer and handles Baltimore's freeze-thaw cycles more predictably. Flat roofs (common on older commercial and multi-unit residential buildings) are priced by the square foot; TPO averages $3 to $5 per square foot for materials and labor combined.

Asphalt shingles carry a manufacturer's warranty of 15 to 25 years depending on grade; Four Twelve typically offers a workmanship warranty of 5 to 10 years on installation. Metal roofs often include 30-year or lifetime warranties against rust and weathering. Confirm exact warranty terms and coverage exclusions at the estimate stage, as terms vary by manufacturer and product line.

Inspection and Estimate Process

Four Twelve begins with a roof inspection, which includes climbing the roof, examining flashing, checking for water damage or active leaks, and assessing deck condition. An inspection takes roughly 30 to 45 minutes for a single-story residential home. The company provides a written estimate that specifies materials, labor, timeline, debris removal, and permit responsibility. If structural damage (rotted decking, sagging trusses) is discovered, the estimate will note that cost separately since deck repair extends the project scope and timeline.

Estimates are free and carry no obligation. Four Twelve can typically schedule inspections within 5 to 7 business days; turnaround for a written estimate is usually 2 to 3 days after the site visit.

How Four Twelve Compares to Other Baltimore Roofing Contractors

Baltimore has both national roofing franchises (like Owens Corning or re-roofing chains) and 20 to 30 independent contractors. Four Twelve occupies the middle ground: established enough to manage full commercial and residential projects without subcontracting labor, but small enough to take on single-family homes and handle custom material requests without minimum project sizes.

Franchise operations typically quote higher prices (10 to 20 percent above market rate in Baltimore) but offer brand-name accountability and, in some cases, extended warranty programs. Independent single-person or two-person crews often undercut Four Twelve's pricing by 15 to 25 percent but may have longer project timelines or less capacity for damage assessment and permitting. Four Twelve's advantage is predictable scheduling, licensed crew oversight, and direct communication without call-center routing.

Choose Four Twelve if you need a roof completed within 2 to 4 weeks with minimal scheduling friction and clear insurance documentation for your lender or homeowner's insurance claim. Choose a lower-cost independent if your timeline is flexible and you are comfortable coordinating permitting yourself. Choose a franchise if you prioritize a recognizable brand and extended manufacturer partnerships.

Who This Suits and Who It Does Not

Four Twelve suits Baltimore homeowners replacing a failing roof within the next 1 to 2 months, commercial property managers maintaining small office or retail buildings, and anyone needing insurance documentation or lender-required contractor vetting. It is a practical fit for rowhouse owners dealing with shared wall considerations and tight roof access.

Four Twelve is not the fit for emergency 24-hour storm damage (they do not staff night call-outs), for homeowners seeking only gutter repair or minor patch work, or for projects requiring specialized slate or cedar shake restoration.

Hours, Contact, and Logistics

Four Twelve operates Monday through Friday, 7 a.m. to 4 p.m., and Saturday by appointment. They serve all of Baltimore proper and inner-ring suburbs within a 10-mile radius of the city. Call or email for scheduling; most initial consultations are conducted on-site rather than by phone quote. Parking is managed per the customer's property (rowhouse homeowners should notify Four Twelve of permit requirements; commercial properties usually have dedicated contractor access).

Four Twelve's focus on licensed operation and material transparency makes it a reliable choice for homeowners and small commercial operators seeking a local roofing contractor with verifiable insurance and clear estimate practices.
