If you’ve been searching for “roof repair near me,” here are the top 5 warning signs that it’s time to call a professional.

- Cracked or missing sections
- Granule loss (you’ll notice sand-like debris in your gutters)
Damaged shingles expose your roof’s underlayment to water, which can quickly lead to leaks or structural rot. The earlier you repair these, the longer your roof will last.
Tip: Walk around your home after heavy winds or storms to spot missing or loose shingles from the ground.
2. Water Stains on Ceilings or Walls

Action Step: Contact a licensed roofing contractor immediately to assess structural integrity before it becomes a safety hazard.
4. Moss, Algae, or Mold Growth
A green roof might look rustic, but it’s actually a problem.
Moss and algae hold moisture against your shingles, accelerating decay and lifting shingle edges over time. In coastal areas like San Francisco, Oakland, or Belmont, the humid air makes this even more common.

✅ Regular cleaning and minor repairs can stop the damage before it spreads — and extend your roof’s lifespan by years.
5. Rising Energy Bills
If your home suddenly feels hotter in summer or colder in winter, your roof might be the reason.
