Exterior Masters in Baltimore: Asphalt Shingle and Metal Roofing for Rowhouses and Older Homes

Exterior Masters is a licensed and insured roofing contractor serving Baltimore's rowhouse stock and residential properties, specializing in asphalt shingle replacement and metal roof installation on homes built before 1980. The company operates across Baltimore County and the city proper, handling both emergency leak repair and planned roof replacement on structures where pitch, age, and material limitations demand practical solutions rather than high-end alternatives.

What Exterior Masters Actually Does

The company focuses on two core materials: standard asphalt shingles (the majority of Baltimore's residential base) and standing-seam metal roofing (growing demand on Victorian-era rowhouses and properties in flood-prone areas). They do not specialize in slate, clay tile, or high-end synthetic materials. Work includes full roof tearoff and replacement, spot repairs on existing roofs, flashing replacement around chimneys and valleys, and emergency tarping. The company is Maryland-licensed and carries general liability and workers' compensation insurance, both required for work in Baltimore.

Materials, Warranties, and Pricing

Asphalt shingle replacement on a typical 1,500-square-foot rowhouse roof runs $6,500 to $9,500 depending on roof pitch, number of valleys, and local material costs. Metal roofing on the same footprint costs $12,000 to $16,000. These figures reflect 2024 pricing and fluctuate with copper and steel commodity costs; confirm current rates directly. Both products come with manufacturer warranties (asphalt typically 20 to 30 years; metal 40 years or longer), though labor warranties from the installer are separate and should be clarified at estimate. Estimates are free and include photos and a written breakdown of materials and labor.

How Exterior Masters Compares to Other Baltimore Roofers

Baltimore has three tiers of roofing contractors. Large national franchises like Owens Corning and GAF-affiliated installers operate in the city but often charge premium labor rates ($8 to $12 per square foot) and carry higher overhead. Local independent contractors, including Exterior Masters, typically charge $5 to $8 per square foot and have faster scheduling during non-storm periods. High-end specialty shops (often based in Annapolis or Columbia) handle complex reconstructions, custom metal work, and period-correct materials on historic homes, at rates 30 to 50 percent above standard replacement.

Choose Exterior Masters if your home needs straightforward asphalt shingle or metal replacement and you value faster scheduling and lower overhead costs. Choose a franchise if your roof is still under warranty and you want a national guaranty to follow you. Choose a specialty contractor if your rowhouse is listed on the National Register or requires slate, clay tile, or architectural copper work.

Licensing, Permits, and Inspection

Maryland requires roofing contractors to hold a Class A or Class B roofing license issued by the state Department of Labor. Exterior Masters carries a Class A license. Baltimore City and Baltimore County both require roofing permits before work begins; the permit process takes three to five business days and costs $100 to $200 depending on jurisdiction. The inspector verifies that the installer used code-compliant materials, proper flashing, and adequate ventilation. Exterior Masters handles permit applications as part of the estimate and project scope.

The Inspection and Estimate Process

After a phone inquiry, the company schedules an on-site inspection within three to five business days. A crew member photographs the roof, climbs the structure to assess decking condition and ventilation, and measures the roof plane. If leaks are reported, the inspector traces water entry to identify whether the problem is shingles, flashing, or underlying damage. The written estimate includes the cost of materials, labor, permits, cleanup, and a timeline (typically five to ten business days for a full replacement). Emergency tarping can be arranged same-day for acute leaks but does not replace permanent repair.

Who This Suits and Who It Does Not

Exterior Masters suits owners of Baltimore rowhouses built between 1910 and 1980, properties with pitch-compatible asphalt or metal roofing, and homeowners seeking faster turnaround than franchises offer. It does not serve owners of flat roofs (which require TPO, PVC, or tar-and-gravel systems outside this company's specialty), homes with custom slate or tile, or properties requiring specialized historic preservation credentials for grant funding or insurance purposes.

Hours and Contact

The company operates Monday through Friday, 7 a.m. to 4 p.m., with emergency tarping available by phone outside these hours. Scheduling is seasonal; spring and fall are busiest; winter permits shorter windows but shorter wait times. Estimates require a phone call or online inquiry; no walk-in estimates are available.

For a Baltimore homeowner facing a leaking rowhouse roof or aging shingles, Exterior Masters delivers licensed work and transparent pricing without the overhead of national brands, making it the practical choice for replacing what failed rather than redesigning it.
