6 Signs You Need Shingle Roof Replacement

  • Roof Age Between 22 and 28 Years

    Florida’s UV rays, heat, and humidity shorten shingle lifespan compared to northern climates. Roofs in this age range are nearing the end of service life regardless of visible wear.

  • Bald Patches or Missing Shingles After Storms

    Even partial loss exposes underlayment, which on older roofs may not withstand extended exposure to rain, wind, and sun.

  • Granule Loss in Gutters or Downspouts

    Granules shield the asphalt mat from UV damage and contraction effects. Significant granule loss accelerates shingle deterioration.

  • Insurance Non-Renewal Due to Roof Age or Visible Wear

    Many Florida carriers use roof age and condition as underwriting factors. Replacing the roof often restores eligibility and lowers premiums.

  • Curling, Cupping, or Lifting Tabs

    Shingles that have lost their seal cannot reseal, making them vulnerable to wind uplift and water intrusion.

  • Repairs Exceeding 25% of Roof Area

    Florida Building Code Section 1511.1.1 requires that if over 25% of your roof area is repaired or replaced within 12 months, the entire roof or section must be updated to current codes. This often makes full roof replacement the better long-term choice.

Our Comprehensive Shingle Roof Replacement Services

Full Tear-Off to the Roof Deck

We remove all existing shingles, underlayment, flashing, and drip edge. Installing new shingles over old voids most manufacturer warranties and violates Florida wind codes — a shortcut we never take.

Roof Deck Inspection and Repair

With the deck exposed, we inspect for rot, delamination, or wind damage. The deck must be smooth, fastened, dry, and gap-free to provide a flat surface. A sealed deck helps prevent water intrusion if shingles are lost. Damaged areas are replaced per proposal, with photos before underlayment installation.

Self-Adhered Peel-and-Stick Underlayment

A Florida-rated peel-and-stick underlayment is applied as a secondary water barrier, offering better protection than traditional felt and safeguarding your home if shingles lift or crack. It may be synthetic or asphalt-saturated felt.

Code-Compliant Flashing and Drip Edge Replacement

New flashing and drip edge are installed at all chimneys, skylights, vents, valleys, sidewalls, and headwalls. Reusing old flashing is a common cause of leaks and is avoided.

Florida-Rated Architectural Shingles Installation

We apply manufacturer-specified six-nail fastening patterns, starter strips along eaves and rake edges, and properly install ridge caps. Roof shingles are installed from the bottom upward, with each course overlapping the one below for proper water shedding. Choose from major manufacturers with options in color, profile, and warranty length.

How to Choose the Right Shingle Roofing Contractor

  • Verify the Contractor’s License

    A valid Florida roofing license is essential. You can check the license status online at MyFloridaLicense.com, and confirm the roofer will handle required reroofing permits in Collier County, including the Roof Replacement Permit Application.

  • Ensure Proper Underlayment & Ventilation

    A quality roof replacement should always include new underlayment and proper attic ventilation. These critical components help protect against moisture intrusion, improve energy efficiency, and extend the life of your roofing system.

  • Ensure the Proposal Specifies the Shingle Manufacturer, Product Line, and Warranty

    Vague descriptions allow substitutions with inferior products. The estimate should also clearly separate labor, tear-off, permits, and inspections; for shingle roof replacement, permits and inspections are required, and manufacturer warranties may not cover damage caused by improper installation.

  • Ask About Flashing & Edge Protection

    A reliable roofing contractor should include new flashing and drip edge installation around important roof details and edges. Proper metal details are critical to preventing leaks, protecting against wind-driven rain, and ensuring the roof system performs long term.

  • Confirm Adherence to Six-Nail Fastening Patterns

    Securing each shingle with six nails is the Florida wind-rated standard, and shortcuts here void warranties and reduce wind resistance.

  • Ask About Debris and Nail Cleanup

    Professional contractors perform magnetic nail sweeps daily and at project completion to keep your property safe. Labor usually accounts for about 60% of total installation cost, and removing old shingles can add to the overall cost.
