5 Signs You Need a New Roof (Before It's Too Late)

Your roof is your home’s first line of defense against Pittsburgh’s unpredictable weather—ice, snow, hail, heat, and heavy rain. But like every part of your house, your roof won’t last forever. Ignoring signs of roof damage can lead to serious problems, from water damage to mold to structural issues.

So how do you know when it’s time to take action?

In this post, we’ll walk you through the top five warning signs that your roof may need to be replaced—before it causes costly damage to your home.

1. ⚠️ Shingles Are Cracked, Curling, or Missing

Take a look at your roof from the ground. Do you notice:

• Shingles that are lifting at the edges?

• Cracks or visible breaks?

• Bald spots where granules are missing?

• Entire shingles missing after a windstorm?

  
  

These are all clear signs that your roof is nearing the end of its life.

In asphalt roofing, shingles are your protective barrier. When they begin to break down—especially after 15–20 years of exposure to sun, ice, and wind—they can no longer keep water out effectively.

Even if only a few shingles are damaged, they can compromise the surrounding areas, leading to moisture infiltration. And once water gets in, it can rot the roof deck and even leak into your attic or ceiling.

2. 💧 You Notice Water Stains or Interior Leaks

One of the most alarming signs of roof failure is seeing water stains on your ceiling or walls. These yellow or brown patches usually appear in the corners of ceilings or along exterior walls.

If you notice:

• A musty odor in the attic

• Damp insulation

• Visible water dripping during storms

• Stained ceiling tiles or drywall

  
  

…it likely means water is getting in through your roof.

Leaks don’t always show up directly below the problem spot. Water can travel along rafters and surfaces, showing up elsewhere inside. That’s why it’s important to call a licensed roofing contractor in Pittsburgh right away if you suspect a leak.

3. 🧊 Your Roof Has Ice Dams or Sagging Areas

In Pittsburgh’s snowy winters, ice dams are a common problem. These form when snow melts off your roof, refreezes near the edges, and traps more water behind it. The standing water can seep under shingles and into your home.

Even worse? Repeated freezing and thawing can wear down shingles fast.

Another warning sign is a sagging roofline. If your roofline doesn’t look straight—or worse, has a dip—it may be due to:

• Water damage weakening the structure

• Rotting decking

• Improper ventilation causing moisture buildup

  
  

This is a serious issue that should be evaluated immediately by a roofing professional. If ignored, sagging roofs can lead to structural collapse.

4. ⏳ Your Roof Is 20+ Years Old

Even if your roof looks okay from the outside, age matters. Most asphalt roofs last 15–25 years, while metal roofs can last 40–70 years.

If your roof was installed more than 20 years ago, you should:

• Check your paperwork or warranty

• Schedule a roof inspection from a local expert

• Be prepared to replace your roof soon—even if you don’t see problems yet

  
  

Old roofing materials become brittle and less effective at withstanding Pittsburgh’s intense freeze-thaw cycles and heavy rains. Waiting too long increases your risk of major leaks and costly repairs down the road.

5. 🧲 Your Roof Has Moss, Algae, or Granule Loss

Let’s talk about the little things—because they can turn into big problems.

Moss & Algae Growth

If you see green or black streaks on your roof, that’s likely moss or algae growing on moist surfaces. Not only is it unsightly, but moss can:

• Trap moisture under shingles

• Accelerate rot and decay

• Add weight to your roof structure

• 
  

Moss tends to grow on shaded areas of your roof or parts that dry slowly after rain or snow.

Granule Loss

Asphalt shingles are covered in tiny granules that protect against UV rays. If you find black grit in your gutters or downspouts, it means your shingles are deteriorating.

Once the granules are gone, shingles quickly break down—and your roof becomes vulnerable.

🧰 Bonus: You’ve Had Frequent Repairs or Storm Damage

Pittsburgh gets its fair share of high winds, hailstorms, and heavy rain. If you’ve had to repair roof damage more than once in recent years, it might be time to consider full replacement.

Repeated patchwork:

• Doesn’t always fix the underlying issues

• Can add up in cost

• Reduces your roof’s ability to protect your home

  
  

Plus, some insurance companies offer better coverage for new roofs—and may even offer discounts if you upgrade to hail-resistant or metal roofing.
