Baltimore’s unique mix of historic rowhomes and detached suburban houses faces a brutal cycle of humid summers and icy winters. A specialized roof is essential here to handle the Chesapeake Bay's moisture and prevent the common "oven effect" in top-floor rooms during July and August.

Granule Loss in Gutters: Heavy sediment in your downspouts indicates your shingles are shedding their protective layer after intense Maryland storms.

Internal Ceiling Stains: Water rings on your top-floor ceilings often signal a breach in the roofing membrane following a heavy summer downpour.

Curling Shingles: Shingles that are "clawing" or buckling are often the result of Baltimore's extreme thermal cycling and high humidity levels.

Ice Damming: Thick ice ridges forming along your eaves during a Maryland freeze indicate poor attic insulation and a failing roof barrier.

Algae Streaking: Black, vertical streaks (Gloeocapsa magma) are a sign of organic growth thriving in our local high-humidity environment.

FAQ: Window Installation in Baltimore

Yes, if your home is in a CHAP (Commission for Historical and Architectural Preservation) district like Fells Point or Bolton Hill, you must get approval for materials and colors to ensure they match the historic character. Our team handles the documentation to ensure your project stays compliant with city code.

For the classic Baltimore rowhome, experts typically recommend TPO (Thermoplastic Polyolefin) or Modified Bitumen. TPO is highly reflective, which helps keep those notoriously hot top-floor bedrooms much cooler during our humid Maryland summers.

High humidity leads to "blue-green" algae growth, which causes those ugly black streaks. Our experts would recommend shingles with copper-containing granules (like StreakFighter technology), which are specifically designed to resist algae in humid coastal-adjacent climates like ours.

While "re-roofing" is legal in some parts of Maryland, contractors generally advise against it in Baltimore due to our heavy snow loads and rain. Removing the old layer allows us to inspect the decking for rot caused by our high annual precipitation, ensuring a much longer-lasting result.

Most residential replacements are completed in 1 to 2 days. However, because the weather can be unpredictable, contractors can monitor local Doppler radar closely and always ensure your home is fully dried-in and protected before any evening storms roll in.
