Project Overview & Hyperlocal Context
Paddy’s recently completed a comprehensive residential roof replacement on Alexandria Drive in Newark, Delaware (19711). Located just steps away from the bustling shopping hub of Suburban Plaza and adjacent to the world-class University of Delaware Science, Technology & Advanced Research (STAR) Campus in College Park, this quiet neighborhood features classic single-family homes that require robust defense against Delaware’s severe humidity, heavy rainfall, and seasonal freeze-thaw cycles that are tough on shingle roofs.
The homeowners reached out to Paddy’s after noticing visible signs of exterior roof distress and degradation. Situated near major local corridors like South College Avenue (Route 896) and Christina Parkway (Route 4), this home was in urgent need of a full system overhaul to restore its structural integrity, weather protection, and curb appeal.
Critical Issues Identified in our Inspection
During our initial roof assessment, our team identified several critical vulnerabilities captured in the project photographs that severely compromised the home’s weather envelope:
-
Heavy Organic Growth & Mold Accumulation: Large patches of vibrant green moss and organic mold had taken root along the lower roof planes, particularly near wall intersections and downspout discharge zones where shade and moisture lingered. This organic growth trapped moisture directly against the shingle granules, rotting the underlying asphalt mats and lifting shingle edges.
-
Ripped, Torn, & Missing Shingles: Severe storm winds and advanced material aging had caused shingles to fracture and rip apart. In key areas near the gutter line, large portions of the shingle face were entirely torn away, leaving underlying wire mesh screening and bare roof deck exposed directly to rainfall.
-
Compromised Flashing & Granule Loss: Widespread granule loss was evident across all roof slopes, drastically reducing the shingles’ UV defense and leaving brittle asphalt substrates vulnerable to water penetration around valleys and wall transitions.
Step-by-Step Replacement Process
1. Complete Tear-Off to Bare Plywood Deck
Our crew stripped away all layers of old, mold-damaged asphalt shingles down to the bare plywood sheathing. Removing every layer allowed us to inspect the entire deck structure for rot or soft spots caused by the missing shingles and trapped moisture.
2. Substrate Remediation & Ice/Water Shield Application
Any water-damaged deck boards were reinforced, and high-performance ice and water shields were installed along critical leak-prone zones, including eaves, valleys, and rakes. A heavy-duty synthetic underlayment was rolled out across the remaining deck, providing an impermeable secondary water barrier.
3. Architectural Shingle Installation
We installed a high-performance architectural shingle system featuring multi-dimensional shadow lines and advanced wind-resistance technology. The clean, uniform grey finish immediately transformed the home’s aesthetic while guaranteeing long-term protection against algae and mold growth.
4. Upgraded Ventilation Systems
To prevent future moisture build-up beneath the deck, new ventilation components were installed along the ridge lines to ensure optimal attic airflow, regulating temperature and preventing damp conditions that foster moss and mold development.
