Most homeowners don’t think about their roof until there’s a leak or a missing shingle staring back at them. But your roof is your home’s first line of defense against everything, rain, wind, snow, and the brutal Illinois sun. Knowing when it’s time for a replacement can prevent costly repairs and protect your investment for decades to come.

At Stan’s Roofing, Siding, Decks & Unlimited Basements, we’ve spent over 58 years helping homeowners in Romeoville and the surrounding communities make that call with confidence. Here’s how to tell if your roof is due for an upgrade.

1. Your Roof Is 20 Years Old or Older

Even the best asphalt shingles have a lifespan. Most roofs last about 20 to 25 years depending on the material, ventilation, and climate. If your home’s roof is pushing that age, it’s time to start planning for replacement — even if it still looks “okay” from the ground.

Older roofs are more prone to leaks and may no longer meet modern building codes or wind ratings.

2. You See Missing, Cracked, or Curling Shingles

Walk around your home and look up. Are shingles starting to curl at the edges or crack in the center? Are there spots where they’re missing altogether?

Shingles that are breaking down or losing granules no longer protect your roof deck from water and UV damage. If multiple sections are affected, patching won’t be enough.

3. There Are Granules in Your Gutters

Take a look inside your gutters the next time you clean them. If you see lots of black, sand-like grit, those are granules from your shingles. This is one of the first visible signs of roof wear.

Granules protect shingles from the sun. Once they start falling off, your roof deteriorates faster, leading to leaks and interior water damage.

4. You Notice Water Stains on Ceilings or Walls

A small water stain on your ceiling might seem harmless, but it’s usually a sign of a slow roof leak. Water can travel far from the original source before it becomes visible inside.

By the time you see the stain, the underlying decking or insulation could already be saturated. Don’t wait for it to get worse — have a professional inspection done right away.

5. The Roof Looks Uneven or Sagging

If you notice dips, waves, or uneven spots on your roofline, it’s a red flag. Sagging usually points to structural damage beneath the shingles. Moisture can weaken the decking or rafters over time, making the roof unsafe.

A sagging roof requires immediate attention from a professional roofer.

6. You Have Mold, Moss, or Algae Growth

While a little green tint might seem harmless, moss and algae can actually trap moisture against the shingles, accelerating rot and decay. Over time, that moisture can seep into your attic or insulation.

If you see consistent growth even after cleaning, it could be a sign that your shingles have lost their protective coating or that there’s excess moisture trapped beneath.

7. Storm Damage or Hail Impact

After a major storm, inspect your roof for dents, missing shingles, or exposed underlayment. Hail and high winds can cause damage that isn’t always visible from the ground.

If you suspect storm damage, call a local roofing expert — not a storm chaser. A professional inspection from a trusted, licensed contractor like Stan’s can help you document the damage and work directly with your insurance company.

Bonus Tip: Don’t Wait for Leaks

Many homeowners assume they can wait until their roof leaks to replace it. The truth is, once a leak appears, water has already made its way through several layers of your roof system. Preventative replacement costs less than waiting until water damage forces the issue.

Why Choose a Local, Family-Owned Roofing Company

When it comes to roof replacement, who you hire matters just as much as the materials you use. National chains and private equity–backed companies often focus on volume and speed. Family-owned companies like Stan’s Roofing, Siding, Decks & Unlimited Basements focus on craftsmanship, communication, and standing behind their work.

We’ve served Illinois homeowners for nearly six decades with honesty, experience, and genuine care — the same way we’d treat our own homes.
