How to Tell If Your Roof Needs Replacing: 6 Warning Signs to Watch For

When’s the right time to replace your roof?

Waiting too long can lead to leaks, water damage, mold, and major repair bills. The good news? Your roof usually gives you signs it’s time to act — you just have to know what to look for.

Here are six key warning signs to know your roof might be due for replacement:

1. Shingles Are Curling, Cracking, or Missing

Shingles are your roof’s first line of defense. If they’re curling at the edges, cracked, or missing in spots, your roof is vulnerable — especially after wind or hail storms.

Kainos Tip: Check your yard or gutters for stray shingles or granules. They’re a clue your roof is wearing out.

2. You See Dark Spots or Stains on the Ceiling

Brown patches or streaks on your ceiling or walls usually mean water is getting in through the roof — and it’s likely been happening for a while. Time is critical here.

3. The Roof Looks Worn or Saggy

From the street, does your roof look uneven or droopy? That could mean moisture damage or weakened roof decking — both signs it’s time to act.

4. Your Roof Is Over 20 Years Old

Most asphalt roofs last 20–25 years. Even if your roof looks okay from the ground, the materials may be aging underneath.

5. Moss or Algae Growth

Moss and black streaks (algae) hold moisture against the shingles. Over time, this weakens the roof surface and leads to premature wear.

6. Your Neighbors Are Replacing Theirs

If your neighborhood was built at the same time and your neighbors are getting new roofs, chances are yours is on a similar schedule.
