HARRISBURG, Pa. - PennZone -- Roof maintenance is often delayed until visible damage occurs, leading to costly repairs and potential structural issues. Twin Mar Roofing is raising awareness about common warning signs that may indicate the need for prompt roof repair.

Even minor roofing issues can escalate if not addressed in time. Regular inspections and timely repairs are critical for preventing water damage, mold growth and energy inefficiency. Twin Mar Roofing has outlined ten indicators that suggest a roof may be compromised:

1. Missing or Damaged Shingles – Shingles that are cracked, curled or missing reduce a roof's ability to provide proper protection against the elements.
2. Water Stains on Ceilings or Walls – Brown discoloration indoors can signal roof leaks, even if the affected area appears small.
3. Sagging Roof Line – A drooping or uneven roofline may suggest underlying structural problems, often caused by water damage or poor construction.
4. Granules in Gutters – The presence of shingle granules in gutters typically indicates significant wear and aging of the roofing material.
5. Daylight Visible Through Attic – Gaps or holes that allow light into the attic also permit water intrusion, requiring immediate attention.
6. Unexplained Increase in Energy Bills – A failing roof can compromise insulation and ventilation, resulting in higher heating and cooling costs.
7. Mold or Mildew on Exterior Walls – Unusual growth patterns on siding may be due to poor drainage or hidden leaks in the roof system.
8. Damaged or Missing Flashing – Flashing around chimneys, skylights and vents that is rusted, bent or absent can allow moisture to enter the structure.
9. Roof Age Exceeding 20 Years – Asphalt shingle roofs typically have a lifespan of about two decades. Older roofs are more prone to deterioration.
10. Moss or Algae Growth – Organic growth can trap moisture against the roof surface, accelerating decay and indicating potential drainage problems.

For those observing one or more of these signs, scheduling a professional roof inspection is a critical step toward preventing further damage. Twin Mar Roofing offers expert assessments and reliable repair services throughout the Harrisburg area.
