Total Exterior Overhaul
London, Ontario | Full Enclosure System
This project involved a complete technical restoration of a 25-year-old residence. We performed a full tear-off down to the deck, installed a premium architectural shingle system with a high-performance ice & water shield, and replaced failing vinyl with Westlake Royal insulated siding.
- Full Deck Inspection & Repair
- GAF HDZ Shingle System
- Westlake Royal Siding Upgrade
- Seamless Gutter Engineering
Structural Plywood Decay
An uninspected deck often hides delaminated plywood and dry rot. This causes "soft spots" where shingles lose their grip, leading to rapid system failure and internal water damage during heavy Ontario storms.
Full Deck Inspection & Repair
Trident performs a 100% surface inspection. We replace any compromised wood with 5/8" CDX plywood, ensuring a rock-solid foundation that prevents future shingle sagging and guarantees maximum wind uplift resistance.
Commodity Shingle Blow-Offs
Standard shingles often lack a dedicated strike zone, leading to "high-nailing" errors. Over time, granules shed and asphalt dries out, leaving your home vulnerable to leaks and UV degradation.
GAF HDZ Shingle System
Trident utilizes the GAF HDZ system with LayerLock technology. This creates a mechanical bond between layers, offering a 210km/h wind rating. Our precision nailing ensures shingles stay locked down for the full 50-year system life.
Uninsulated Vinyl Failure
Traditional siding is thin and brittle, offering zero thermal resistance. Cracks or loose panels also create "bug highways" and trap moisture against your home's framing, causing hidden rot and structural decay.
Westlake Royal Siding Upgrade
Trident installs Westlake Royal insulated siding with integrated high-R-value foam. This acts as a continuous "blanket," significantly lowering energy bills while providing 300% more impact resistance than standard vinyl.
Sectional Seam Leaks
Store-bought gutters have seams every 10 feet that eventually fail due to expansion. This dumps water directly at your foundation, leading to basement flooding, soil erosion, and costly foundation repairs.
Seamless Gutter Engineering
Trident engineers custom, seamless gutters on-site from heavy-gauge aluminum. By eliminating seams and using heavy-duty hidden hangers, we ensure water is diverted far from your foundation and landscaping.
The Efficiency Upgrade
St. Thomas, Ontario | Modern Siding & Light
Transformation of a standard 1990s build into a modern, energy-efficient home. We integrated Velux skylights for natural light and replaced dated siding with a high-performance insulated system designed for the local climate.
- Velux Skylight Integration
- Premium Siding Overhaul
- Airflow & Ventilation Tuning
- Technical Metal Flashing
Failing Deck-Mount Units
Old skylights often rely on simple caulking. Once the seal fails, water seeps into your rafters and insulation, causing massive ceiling damage and mold before you even notice a drip inside.
Velux Skylight Integration
Trident installs Velux "No-Leak" skylights featuring a three-layer water protection system. This floods your interior with light and superior insulation while offering a 10-year installation warranty.
Air Infiltration & Drag
Aged siding loses its seal, allowing cold drafts to penetrate walls and noise to leak in. The lack of a proper technical house wrap often leads to moisture buildup within the wall cavity.
Premium Siding Overhaul
Trident’s siding overhaul includes a technical moisture barrier and precision-fit composite panels. This creates an airtight seal that eliminates drafts and dampens exterior noise by up to 50%.
Stagnant Attic Heat
Poor ventilation bakes shingles from beneath in summer. In winter, this heat causes snow to refreeze at the gutters, creating damaging ice dams and "attic rain" (internal condensation).
Airflow & Ventilation Tuning
Trident calculates the exact Net Free Area required. We tune the system using high-flow ridge vents and clear soffit intakes, ensuring fresh air preserves your roof deck and keeps your home dry.
Compromised Transitions
Most leaks occur where the roof meets a wall. Poorly installed flashing allows water to wick behind siding and rot the home's framing and interior drywall over time.
Technical Metal Flashing
Trident uses heavy-duty metal, hand-bent on-site to create a perfect mechanical seal. Our flashing engineering ensures water is shed away without ever relying on temporary sealants.
Architectural Precision
Kitchener, Ontario | Technical Metal Work
A precision-focused job emphasizing the technical "Trident Edge." We replaced failing wood soffits with aluminum and performed custom metal capping around critical roof transitions to ensure 100% water diversion.
- Custom Metal Capping
- Soffit & Fascia Replacement
- Chimney Flashing Overhaul
- High-Capacity Drainage
Exposed Wood Trim Decay
Bare wood trim is a magnet for water. Once paint peels, wood absorbs moisture, leading to rapid rot and structural failure that spreads into the home's main framing.
Custom Metal Capping
Trident wraps all exposed wood trim in custom-formed aluminum. This is 100% maintenance-free and creates a permanent weather-tight seal that snow and rain can never penetrate.
Clogged Wooden Intakes
Old wood soffits often get painted over, blocking airflow. This leads to attic moisture issues and also provides an easy entry point for birds and rodents to nest and cause damage.
Soffit & Fascia Replacement
Trident replaces old wood with a high-flow aluminum system. This ensures your attic can "breathe" properly to prevent mold, while the heavy-duty fascia provides a crisp, maintenance-free finish.
Corroded Masonry Seals
Water wicks into the chimney stack when flashing fails. Winter freeze-thaw cycles cause bricks to crack and mortar to crumble, eventually leading to chimney collapse or interior leaks.
Chimney Flashing Overhaul
Trident engineers a multi-stage technical flashing system. We use custom-bent saddles and counter-flashing that diverts 100% of water flow around the masonry, protecting the stack.
Undersized Gutter Overflow
Standard 4-inch gutters overflow during heavy storms, rotting the fascia board and flooding your garden beds, leading to soil erosion and foundation seepage.
High-Capacity Drainage
Trident upgrades the capacity with larger 6-inch troughs and 3x4 downspouts. This is engineered to handle extreme rainfall, moving water efficiently away from critical structures.
