Methodology
How We Ranked the Best Roofers in Calvert County, MD
Every roofer on this list met four objective criteria:
Active Maryland Home Improvement Commission (MHIC) licensing. Verified through the MHIC public license search. Any contractor without a current MHIC license is automatically excluded.
Minimum 4.5-star Google rating with at least 50 reviews. Review depth matters more than a perfect score from 10 reviews. We weighted review count alongside rating.
Demonstrated local service history in Calvert County. Either a physical location in or near Calvert County, or a documented service area covering Calvert County as a primary market.
Advanced manufacturer credentials where applicable. Owens Corning Platinum, GAF Master Elite, or CertainTeed 4-Star ShingleMaster status reflects extended training, warranty access, and accountability that standard licensing does not.
Independence note: JDH Remodeling produces this list. JDH ranks #1 because of verifiable credentials: Owens Corning Platinum (held by fewer than 1% of US roofers) and HAAG Master Roof Inspector. The other 4 contractors are evaluated against the same criteria, with the same level of detail.

FAQ
Choosing a roofer in Calvert County
Most full asphalt-shingle roof replacements in Calvert County run $9,500 to $20,000 in 2026. Smaller or simpler roofs can fall below that range; large, steep, or complex roofs run higher. Always get the scope and warranty in writing.
Maryland home-improvement contractors must hold an active MHIC license. Ask for the number and look it up on the Maryland Department of Labor's license-lookup tool. JDH Remodeling's MHIC license is #137491. Also confirm general-liability insurance before any work begins.
Ask for the MHIC license number, proof of liability insurance, a written scope of work, the manufacturer warranty offered, and references or recent local addresses. Get 2 or 3 written estimates and compare what's actually included, not just the bottom-line price.
A manufacturer warranty (e.g. Owens Corning's 50-year Platinum) covers the materials and is only available through certified contractors. A workmanship warranty covers the installer's labor. The strongest protection is having both, so ask each company which they provide and for how long.
