Maryland Roofing Repairs & Replacement Contractor

Get expert roofing repairs, and a 100% Lifetime Labor Warranty on all roof replacements. Costly leaks and ice dams will be banished forever, since we’ll do the job right the first time with durable CertainTeed shingles. (Oh… and Dan’s a CertainTeed Certified Shingle Master).

Seamless Gutters, Downspouts, and Gutter Guards

Keep your home’s foundation stable and dry with “no-leak” seamless gutters, downspouts, and gutter guards. When they’re properly installed in the right locations, they’ll protect your home, plants, gardens, and landscape from costly water damage. Our gutters are available in several styles, materials, and colors to perfectly match your home.


Let the natural sunlight flood into any room. We’ll install a new skylight, or replace an existing one with stylish, energy-efficient models from Wasco and Velux. Virtually leak-proof, you can choose from many options, including remote opening, pre-installed blinds, and much more.

House and Attic Ventilation

The right home and attic ventilation will protect your roof, keep your living space warm in the winter, cool in the summer, and prevent water damage, deadly moldand mildew. We’ll help you determine which combination of ridge vents, soffit vents, attic whole-house fans, and gable vents will work best in your home.

Vinyl Replacement Windows 

Save money and add value and beauty to your home with energy-efficient replacement windows made by Simonton. All windows are low-E Argon, which keeps the heat in – and the cold out. They’re reliable, durable, and easy-to-maintain. Many styles, options, and colors to choose from. Double-hung, casement, bay windows & more.

Vinyl Siding and Trim

Replace your damaged, out-of-style, or plain ugly siding with long-lasting vinyl siding manufactured by CertainTeed. It’s easy-to-clean, virtually maintenance-free, plus mimics the beauty and texture of cedar. Available in wide spectrum of colors, and will never fade.
