The Foundation of Your Roof: Deck Protection
A roof is only as good as the wood it is nailed to. JDH Remodeling is a 3rd-generation roofing authority 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 structural audits for Calvert, St. Mary’s, Charles, and Anne Arundel counties. As an Owens Corning Platinum Preferred Contractor, we utilize Synthetic High-Perm Underlayment and Non-Destructive Testing (NDT) to verify your Structural Decking Integrity before installation, ensuring a 100% moisture-tight home envelope.
Forensic Substrate Triage
Standard roofing estimates focus on the color of your shingles. At JDH Remodeling, we focus on the health of your deck. Before a single nail is driven, our technical team performs Non-Destructive Testing (NDT) to identify Substrate Saturation and delamination that could compromise your roof foundation.
Operating from our St. Leonard Headquarters, our forensic units are staged daily near the MD-235 and MD-4 intersection to ensure that every roof foundation in Southern Maryland meets the HAAG Master Level standard.

Why Synthetic Underlayment is Better than Felt Paper
In Maryland's high-humidity climate, JDH exclusively utilizes Owens Corning® Deck Defense. Unlike traditional felt paper, Synthetic High-Perm Underlayment is non-organic, meaning it will not rot or support mold growth when exposed to Substrate Saturation. This high-performance layer provides superior Fastener Pull-through Resistance during high-wind events and allows moisture vapor to escape your attic, preventing the Delamination Triage issues that lead to structural decay.
Shielding the Foundation
In Maryland, the most common roof failures happen at the joints. We utilize Self-Adhering Ice & Water Shields to create a secondary, watertight gasket in areas where Capillary Action and Hydrostatic Pressure are most aggressive.
Valley Fortification
Valleys handle the highest volume of water. We reinforce these "canals" with heavy-duty barriers to prevent Substrate Saturation during torrential Chesapeake storms.
Ice Dam Defense
We seal the bottom edges of your roof to block water backed up by ice dams. This prevents moisture from "wicking" into your Structural Decking and causing delamination.
Self-Healing Seals
Our armor "grabs" every nail that passes through it. This creates a permanent, rubberized seal around every fastener, ensuring Substrate Integrity for the life of your roof.
St. Leonard Logistics Center
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 structural audits for Calvert, St. Mary’s, Charles, and Anne Arundel counties.
Engineered Substrate Shielding
Standard felt paper is a relic of the past. As an Owens Corning Platinum Preferred Contractor, we utilize 3rd-generation materials designed to protect the Structural Decking Integrity of your Maryland home for 50+ years.
Synthetic High-Perm
Unlike organic felt that traps moisture, our Synthetic High-Perm Underlayment allows water vapor to escape your attic, preventing internal rot and Substrate Saturation.
Tear Resistance
Our shielding features extreme Fastener Pull-through Resistance. This ensures your foundation stays intact even during the high-velocity wind events common in Calvert and St. Mary's counties.
UV Stability
While felt paper degrades within hours of exposure, Owens Corning® Deck Defense is UV-stable for up to 6 months, ensuring your Substrate Integrity is protected during the entire build.

Every roof foundation we install is managed through our St. Leonard Headquarters. Our HAAG Master Level Inspectors ensure your underlayment exceeds VA and FHA standards to protect your long-term home value.
Operating near the MD-235 and MD-4 intersection, we provide rapid-response structural audits for the entire Southern MD region.
Closing the Deal with
Substrate Integrity
In Southern Maryland, roof condition is the #1 cause of delayed real estate closings. Lenders—especially for VA and FHA loans—require verifiable proof that the roof deck is structurally sound. A "new roof" installed over rotten wood is a liability that can kill your home appraisal.
