Cost Factors You Can Control

Two homes with the same leak can price out differently. Here is why and how to influence the number.

Access and safety
1. Steeper or taller roofs require more safety gear and time.
2. Tight lots or limited driveway space slow staging.
Materials and match
1. Architectural shingles cost more than 3-tab.
2. Color matching old shingles may require a larger repair area.
Underlayment and decking condition
1. Saturated felt or synthetic underlayment must be replaced.
2. Soft decking from rot adds labor and material.
Flashing and details
1. Chimneys, skylights, and valleys take skilled labor.
2. Custom metal work costs more than sealant-only fixes.
Timing and weather
1. Emergency calls after a Nor’easter or hail event increase demand.
2. Winter work is slower and may require ice mitigation.

Asphalt vs Metal vs Flat: Cost Nuances by Roof Type

Each system has different failure points and repair tactics.

Asphalt shingles
1. Most common on regional homes.
2. Lifespan typically 15 to 30 years.
3. Cost effective for minor and moderate repairs.
Metal panels
1. Standing seam and exposed fastener systems differ.
2. Lifespan often 40 to 70 years.
3. Repairs focus on fasteners, seams, and flashing.
Flat and low-slope membranes
1. EPDM, TPO, and PVC dominate on commercial and some homes.
2. Seams, penetrations, and drains are common issues.
3. Repairs use compatible patches and heat welds.

Maintenance insight

Metal reflects heat and can reduce cooling load.
Flat roofs need routine drain cleaning to avoid ponding.
