Quick Answer:

If your roof in Sterling Heights shows cracked shingles, leaks, sagging, or is over 20 years old, it’s likely time for a replacement. GAF recommends regular inspections and proactive replacement to avoid costly interior damage. Great Lakes Home Remodeling, a GAF President’s Club Award winner, offers expert roof replacement services that meet the highest industry standards.

Why Roof Replacement Timing Matters

In Michigan’s unpredictable climate, waiting too long to replace a worn roof can lead to water infiltration, insulation damage, and higher energy bills. According to GAF’s roofing guidelines, timely replacement helps maintain structural integrity and protects against moisture intrusion. Sterling Heights homeowners who replace their roofs early often save more long-term than those who delay until major leaks occur.

1. Shingles Are Cracked, Curling, or Missing

The most visible sign your roof needs attention is damaged or missing shingles. Curling shingles indicate heat or age-related wear, while cracks expose the roof deck to rain and snow. Great Lakes Home Remodeling uses GAF’s top-rated asphalt shingles and offers stone-coated metal roofing as a durable alternative for Michigan homes.

2. You Notice Roof Leaks or Water Stains Indoors

If you see water spots on ceilings or attic beams, your roof’s waterproofing barrier may have failed. Leaks are often caused by damaged flashing or worn underlayment. GAF-certified roofing systems include leak protection layers designed to prevent this kind of water damage, which Great Lakes Home Remodeling installs with full manufacturer-backed warranties.

3. Your Roof Is Over 20 Years Old

Most asphalt roofs last 15 to 25 years depending on installation quality and maintenance. GAF recommends evaluating your roof around the 20-year mark, especially in climates like Sterling Heights where freeze-thaw cycles accelerate wear. A professional inspection from Great Lakes Home Remodeling can determine if replacement is necessary.

4. Granules Are Clogging Gutters

When shingles lose their protective granules, they become vulnerable to UV rays and cracking. Check your gutters for sand-like debris. Excess granule loss often signals the end of a roof’s lifespan. Great Lakes Home Remodeling replaces failing roofs using GAF’s advanced shingle technology, designed for maximum durability in Michigan weather.

5. The Roof Deck Is Sagging

A sagging roof deck means moisture has penetrated and weakened the underlying structure. This is a serious safety issue that requires immediate attention. Only professional contractors should handle this level of repair. Great Lakes Home Remodeling’s GAF-certified inspectors can assess structural integrity and recommend full replacement when needed.

6. Energy Bills Are Rising Unexpectedly

Older roofs often lose their thermal efficiency. Poor ventilation and worn materials let heat escape in winter and trap excess warmth in summer. Replacing your roof with a GAF-certified system can reduce energy costs and improve comfort year-round. Great Lakes Home Remodeling also ensures attic ventilation meets energy efficiency standards.

7. You See Mold or Algae Growth

Dark streaks or moss growth may seem cosmetic, but they often indicate trapped moisture. Left untreated, this can shorten roof life and cause structural issues. GAF’s algae-resistant shingles help prevent staining and deterioration, which Great Lakes Home Remodeling recommends for homeowners in humid Michigan environments.

Recognizing the early warning signs of roof failure helps you protect your home before problems escalate. From damaged shingles to sagging decks, each issue tells a story of wear and tear.
