Flat Roofing Warning Signs
-
Blistering or Bubbling – Air or moisture trapped under the membrane expands with heat, leading to bubbles. If they burst, water can penetrate and cause leaks.
-
Cracks, Splits, or Tears – Aging, UV exposure, and temperature changes can cause the membrane to crack, split, or tear, allowing water infiltration.
-
Pooling Water – Standing water for more than 48 hours indicates poor drainage, which can lead to leaks, structural stress, and membrane deterioration.
-
Membrane Seams Separating – Seams can pull apart due to weathering or poor installation, creating entry points for water that spreads beneath the roof.
-
Water Leaks Inside the Building – Dripping, stains, or mold indicate a compromised membrane or flashing, often with water traveling far from the actual leak.
-
Sagging or Low Spots – Sunken areas collect water, adding weight and increasing the risk of leaks and structural damage.
-
Multiple Roof Layers – Additional layers can hide problems, trap moisture, add weight, and make repairs more complex and costly.
Shingle Roofing Warning Signs
-
Visible Tar Underlayment – If the black tar paper or fiberglass mat is showing, the shingles are severely worn or missing, leaving the roof exposed to leaks.
-
Curling Shingle Edges – Shingles that curl upward or claw inward indicate aging, heat damage, or poor ventilation. They are prone to breaking and water intrusion.
-
Brittle, Cracked, or Missing Shingles – Sun exposure, weather conditions, and age cause shingles to become weak, crack, or blow off, exposing the roof to damage.
-
Bald Spots on Shingles – Missing granules reduce protection against UV rays and moisture. If granules are collecting in gutters, the shingles are deteriorating.
-
Leaks in the Attic or Top Floor – Water stains, mold, or dripping in the attic signal roofing failure. Even a small leak can lead to major structural damage over time.
-
Sagging Roof – A drooping or uneven roofline suggests underlying structural issues, often due to prolonged water damage, excess weight, or failing supports.
-
Multiple Roof Layers – Adding new shingles over old ones traps heat, accelerates wear, and makes repairs more difficult and costly. Removing old layers ensures a longer-lasting roof.

Age of Roof - # Layers of Roof
Understanding the history of your roof is crucial in determining its expected lifespan. Important factors to consider include the number of layers, the original installation date, and the type of roofing materials used. At Gaby Roofing, we prioritize this knowledge to provide comprehensive assistance and ensure the longevity of your roof.
Unlike many other roofers who rely on subpar materials from local home improvement stores, Gaby Roofing takes pride in sourcing prime quality materials exclusively from trusted contractor supply warehouses. With our strong relationships with leading roofing suppliers, we can guarantee the availability of top-notch materials without any delays or backorders. We believe in transparency and strive to exceed your expectations every step of the way.
If your roof has multiple layers due to patchwork over the years, it may be time for a total replacement. It's essential to consult your local city building department as many ordinances limit the number of allowable roof layers. At Gaby Roofing, we often recommend a full roof replacement because it's the only solution we can confidently guarantee, ensuring the highest level of durability and success for your roof.
Trust Gaby Roofing for all your roofing needs, whether it's a new roof installation or ongoing maintenance. We are committed to delivering exceptional craftsmanship and reliable solutions that stand the test of time. Contact us today at 201-638-8556 to experience the Gaby Roofing difference.
