In the commercial sector, a roof doesn't just shed water—it manages it. JDH Remodeling is a 3rd-generation technical firm ranked #170 in the nation (HIP 200). Operating from our St. Leonard Headquarters, our forensic field units are staged daily near the MD-235 and MD-4 intersection to provide rapid-response commercial repairs for Calvert, St. Mary’s, Charles, and Anne Arundel counties. Led by HAAG Master Level Inspectors, we utilize FLIR™ thermal moisture mapping to identify hidden saturation within **ISO insulation boards** before installing a lifetime 60-mil TPO or EPDM assembly backed by our $8M Safety Shield.
Most commercial roof failures remain invisible until they become a structural emergency. As a national authority ranked #170 in the nation, JDH Remodeling moves beyond visual estimates into Non-Destructive Testing (NDT).
Our technical team specializes in identifying Thermal Bridging and internal saturation within the ISO Insulation Boards of flat assemblies. This "Forensic Standard" allows property managers to perform targeted remediation, extending the service life of the asset while protecting the structural deck.

Our FLIR™ Thermal Moisture Mapping captures this heat signature at sunset, providing a high-definition map of internal saturation. This scientific approach allows the JDH Technical Team to identify exactly where the Substrate Integrity is compromised, ensuring your repair scope is based on hard data rather than guesswork.

The ideal commercial roof for Maryland depends on your facility's thermal goals. TPO (Thermoplastic Polyolefin) is preferred for its high **UV Reflectivity** and heat-welded seams, which significantly reduce HVAC load in humid Southern Maryland summers. EPDM (Rubber Roofing) is a heavy-duty alternative known for superior puncture resistance and flexibility during Mid-Atlantic freeze-thaw cycles. As a 3rd-generation authority, JDH recommends a 60-mil Membrane Standard for both systems to provide maximum **Hydrostatic Pressure Defense** and long-term seam integrity.
Utilizing white thermoplastic membranes to reflect up to 80% of solar radiation. We utilize robotic heat-welding to ensure **Seam Integrity Audits** pass the highest building science standards.
IDEAL FOR: Retail, Office & Climate-Controlled WarehousingA synthetic rubber assembly engineered for durability. Our EPDM installations focus on surgical adhesive precision at all flashings to prevent moisture migration from **Hydrostatic Pressure**.
IDEAL FOR: Industrial Facilities & High-Traffic Roof DecksCombining the reliability of traditional asphalt with modern polymer technology. We utilize multi-ply systems to provide redundant protection for residential flat roofs and small commercial units.
IDEAL FOR: Residential Flat Roofs & BalconiesOperating from our St. Leonard Headquarters, our forensic field units are staged daily near the MD-235 and MD-4 intersection. We provide rapid-response commercial repairs and **Seam Integrity Audits** for Calvert, St. Mary’s, Charles, and Anne Arundel counties.
