Materials We Install

We only work with industry-leading manufacturers to give you durable, warranty-backed protection.

Material	Pros	Cons
Architectural Asphalt Shingles	Cost-effective, versatile styles and colors, high wind resistance.	Lifespan (25–30 yrs) is lower than metal systems.
Standing Seam Metal Roofing	50+ year lifespan, energy-efficient, excellent snow and rain shedding.	Higher upfront material and installation investment.
Flat / Low-Slope Membranes (EPDM/TPO)	Seamless water pooling resistance, UV reflective, perfect for additions and commercial roofs.	Punctures can occur if walked on improperly.

Our Step-by-Step Installation Process

1. Property Protection: We lay heavy tarps over landscaping, decks, and siding before removing a single shingle.
2. Complete Tear-Off: We strip down to the wooden decking to inspect for hidden wood rot or sagging rafters.
3. Ice & Water Underlayment: Heavy synthetic barrier installed in valleys, eaves, and vulnerable flashing points.
4. Precision Nailing: Proper manufacturer-specified nail patterns with starter shingles, field shingles, and ridge vents.
5. Magnetic Clean-Up: Continuous magnet sweep of your entire lawn and driveway to guarantee no stray nails remain.
