At GreenGo Roofing, we understand that your roof is your home’s first defense against the elements. Whether you have a flat roof, tile roof, or shingle roof, recognizing the signs of wear and tear can save you from expensive repairs and structural damage. Over time, all roof types can fail due to weather exposure, aging, or poor maintenance. Below, we walk you through the warning signs that it’s time to replace your roof—regardless of its type.
Signs It’s Time for a New Roof or Roof Restoration
1. Flat Roof Issues: Pooling Water, Cracks, and Membrane Damage
Flat roofs are standard on modern homes and commercial buildings but require regular maintenance to stay functional. Warning signs that it’s time to replace or even restore the surface of a flat roof include:
- Pooling Water: Flat roofs should have proper drainage to prevent standing water. If water pools for more than 48 hours, it can damage the roof membrane and structure.
- Blisters and Cracks: Small blisters or cracks in the roofing membrane allow water to seep through, leading to leaks and further deterioration.
- Damaged Seams: Flat roofs rely on seams to hold the membrane in place. If seams peel or crack, water can penetrate the roof, causing leaks and rot.
- UV Damage: Prolonged sun exposure can cause the membrane to deteriorate and lose its protective layer over time.
Ignoring these signs can lead to water intrusion, mold growth, and costly interior damage. At GreenGo Roofing, we specialize in flat roof inspections and replacements using modern, durable materials like Self-Adhered Modified Bitumen (SBS and APP) and Stitch-Bond Polyester Embedded Coatings.
2. Tile Roofs: Cracked, Loose, or Damaged Tiles
Tile roofs are renowned for their durability, elegance, and longevity—lasting up to 100 years with proper care. However, they are not immune to wear and tear. Common signs of tile roof problems include:
- Cracked or Broken Tiles: Individual tiles can crack due to impact, weather, or age. Damaged tiles expose the underlayment to moisture, which can lead to leaks.
- Loose or Missing Tiles: Strong winds, improper installation, or aging can cause tiles to loosen or fall, compromising your roof’s ability to protect your home.
- Worn Underlayment: The underlayment beneath the tiles provides critical waterproofing. Even if the tiles look fine, deteriorating underlayment can cause leaks.
At GreenGo Roofing, we assess tile roofs carefully to identify whether the tiles or underlayment need replacing. Ignoring damaged tiles can cause costly structural issues, so it’s best to address them early.
3. Shingle Roofs: Curling, Missing, and Granule-Loss Shingles
Due to their affordability and reliability, asphalt shingle roofs are among the most common roofing types. However, they typically last 20–25 years and can show clear signs of failure as they age. Look for:
- Curling or Buckling Shingles: When shingles warp, curl, or buckle, they lose their ability to protect against moisture and UV damage.
- Missing or Cracked Shingles: Storms, aging, or improper installation can cause shingles to crack, break, or disappear altogether, leaving your roof vulnerable to leaks.
- Granule Loss: Shingles are coated with granules to protect against UV rays and weather. If you notice granules in your gutters, your shingles are nearing the end of their lifespan.
- Bald or Dark Patches: Bare spots on shingles indicate heavy wear and signal that your roof no longer provides sufficient protection.
At GreenGo Roofing, we recommend replacing shingle roofs that are visibly worn or nearing the 20-year mark. Addressing these issues early helps prevent leaks, rot, and costly repairs to the home’s interior.
4. Leaks and Water Damage
Leaks are a universal warning sign across flat, tile, and shingle roofs. Water damage doesn’t just affect your roof—it can spread to your walls, ceilings, and even the foundation. Signs of water intrusion include:
- Water stains on ceilings and walls
- Damp patches, mold, or mildew in attics or crawl spaces
- Persistent drips during heavy rain
For flat roofs, leaks often stem from pooling water or damaged seams.
Cracked tiles or deteriorated underlayment are the main culprits for tile roofs.
For shingle roofs, missing or warped shingles are usually to blame.
At GreenGo Roofing, we advise immediate action at the first sign of leaks to avoid extensive structural damage.
5. Sagging Roofs: A Structural Red Flag
A sagging roof is a significant cause for concern across all roofing types. It signals a structural failure that needs urgent attention. Common causes include:
- Flat Roofs: Pooling water weakens the membrane and decking, causing sagging over time.
- Tile Roofs: The weight of tiles can strain older roof structures, particularly if water damage has compromised the decking.
- Shingle Roofs: Water intrusion and aging wood can cause the roof deck to weaken and sag.
If you notice any dips, uneven areas, or visible sagging, contact GreenGo Roofing immediately for an inspection. A sagging roof poses a safety risk and can lead to a complete collapse if left unaddressed.
6. Daylight Through the Attic
If sunlight is streaming through the roof boards in your attic, it’s a clear indicator of gaps, holes, or failing roofing materials.
- Flat Roofs: Damaged seams or punctures allow light (and water) to penetrate.
- Tile Roofs: Cracks in tiles or gaps in the underlayment can let light through.
- Shingle Roofs: Missing shingles or weakened decking create openings for light, water, and pests.
At GreenGo Roofing, we perform thorough inspections to identify and repair the source of the problem. If gaps are widespread, a complete roof replacement may be necessary.
7. Rising Energy Bills
A poorly functioning roof can cause your heating and cooling systems to work overtime, increasing energy bills. Signs include:
- Drafts or uneven temperatures throughout the house
- Poor insulation due to damaged or missing roofing materials
For flat roofs, damaged membranes reduce insulation effectiveness.
For tile roofs, missing tiles can disrupt ventilation.
For shingle roofs, worn-out shingles allow heat and cool air to escape.
A new roof can improve energy efficiency, saving you money in the long run.
