Mervin Construction | General Contractors & Roofing in Severn, MD 21144

Yes, we frequently address these common local issues. Roof nail pops in Severn are often caused by the natural expansion and contraction of roofing materials with our seasonal temperature swings. Our roof inspection service identifies the cause—whether it's improper installation or deck movement—and we perform precise repairs to resecure the shingles. For ventilation problems, which can lead to attic moisture and higher energy bills, we assess and correct airflow to protect your roof's structure and improve home efficiency, often as part of a repair or replacement project.

Our process begins with a free, detailed consultation at your Severn home to discuss your vision, budget, and the best use of your outdoor space. For decks, we handle everything from design and securing any necessary permits to construction using durable, weather-resistant materials. For patios, we specialize in masonry and concrete, offering various finishes for walkways, retaining walls, and outdoor kitchens. Throughout the project, we maintain clear communication, manage all construction phases professionally, and ensure the final result is a sturdy, well-crafted addition you can enjoy for years.
