As Marcel Proust once said, " The real voyage of discovery consists not in seeking new landscapes, but in having new eyes. "

Sometimes, the signs of roof damage are right in front of you—you just need to know what to look for. Let Seal Tight Construction help you see those signs clearly before they become major problems. In this blog, we’ll cover the top 10 signs you need a roof replacement, so you can take action before minor issues turn into major headaches.

1. Your Roof Is Over 20 Years Old

Most roofing materials, such as asphalt shingles, have a lifespan of 20 to 25 years. If your roof is approaching or exceeding that age, it’s time to start considering a roof replacement, even if it appears to be holding up well. Older roofs are more susceptible to damage and may fail unexpectedly.

2. Curling or Buckling Shingles

When shingles start to curl or buckle, it’s a sign that they are past their prime. Curled shingles can lead to water infiltration, which causes leaks and damage to the underlying structure. If you notice this on multiple sections of your roof, a replacement is likely necessary.

3. Missing Shingles

Missing shingles are an obvious sign of roof damage. While a few shingles can be replaced, widespread shingle loss after a storm or from age indicates that your roof is no longer protecting your home properly. It’s often more cost-effective to replace the entire roof than to keep patching it.

4. Shingle Granules in Your Gutters

Asphalt shingles shed their protective granules over time, which can be spotted in your gutters or downspouts. These granules help protect your shingles from UV rays and weather elements. If you’re seeing large amounts of granules, your shingles are wearing down, and a roof replacement may be needed.

5. Sagging Roof Deck

A sagging roof is a severe issue that typically indicates structural problems. This can be caused by water damage, rot, or even improper roof installation. If you notice your roof sagging in any area, it’s a clear sign that you need immediate attention and likely a full roof replacement.

6. Daylight Through the Roof Boards

If you go into your attic and notice sunlight streaming through the roof boards, it’s a sign that your roof has holes or cracks. Any gaps in the roof can allow water to penetrate, leading to leaks and serious interior damage. Don’t wait—this is a surefire sign you need a new roof.

7. Water Damage of Leaks

Water stains on your ceilings or walls are often signs of a leaky roof. While small leaks can sometimes be repaired, repeated leaks indicate that the roofing system is compromised. If you’ve experienced multiple leaks, it’s time to consider a roof replacement to avoid further water damage.

8. Mold, Moss, or Algae Growth

While moss and algae might seem like minor cosmetic issues, they can lead to serious damage if left untreated. Moss holds moisture against the roof surface, which can cause shingles to deteriorate more quickly. If moss, mold, or algae growth is widespread, it’s a sign your roof may need to be replaced.

9. Damaged Flashing

Flashing around chimneys, skylights, and vents is essential to preventing water from seeping into your home. If the flashing is cracked, damaged, or separated from the roof, it can cause leaks. While flashing can sometimes be repaired, extensive damage might require a roof replacement to ensure everything is sealed properly.

10. Increased Energy Bills

If your heating or cooling bills have been creeping up, it could be a sign that your roof is no longer providing proper insulation. A failing roof can allow air to escape, forcing your HVAC system to work harder. Upgrading to a new, energy-efficient roof can help lower your energy costs and keep your home comfortable year-round.
