How to Know When It’s Time to Replace Your Roof

Your roof is your home’s first line of defense against the elements. But over time, even the most

well-built roof can wear down. Knowing when to replace your roof can save you from costly

repairs, water damage, and structural issues. Here are the most common signs it’s time for a roof

replacement:

1. Your Roof is 20+ Years Old

Most asphalt shingle roofs last between 20-25 years. If your roof is reaching or past that age, it

may be time to consider a replacement—even if it still looks okay from the ground.

2. Shingles are Curling, Cracking, or Missing

Curling edges, cracked surfaces, or entire shingles missing are clear signs of deterioration.

Damaged shingles leave your roof vulnerable to leaks and further damage, especially during

Colorado’s harsh weather seasons.

3. Granules in the Gutters

If you notice black sand-like granules accumulating in your gutters, it’s a sign your shingles are

breaking down. These granules protect your roof from UV damage and water infiltration, so their

loss means your roof is losing its effectiveness.

4. Sagging or Uneven Rooflines

A sagging roof is a red flag indicating structural issues, often due to prolonged water damage or

rotting decking underneath the shingles. This issue should be addressed immediately.

5. Water Leaks or Stains on Ceilings

If you spot water stains, bubbling paint, or actual drips in your home, your roof is likely

compromised. Even small leaks can lead to mold, insulation damage, and major repairs if

ignored.

6. Moss, Mold, or Algae Growth

Excessive moss or algae growth on your shingles can indicate trapped moisture, which shortens

your roof’s lifespan. While it may look like a cosmetic issue, it’s often a sign of deeper problems.

7. Rising Energy Bills

A failing roof can affect your home’s insulation and ventilation, leading to higher heating and

cooling costs. If you’ve seen an unexplained increase in your energy bills, your roof could be the

culprit.
