Top 5 Signs You Need a New Roof—Before It’s Too Late
Your roof is more than just a layer of shingles, it’s your home’s first and most critical line of defense against wind, rain, snow, heat, and everything in between. It protects your family, your belongings, and the structural integrity of your house day in and day out. But because we rarely get an up-close look at it, it’s easy to forget that your roof takes a beating with every storm, season change, and summer heat wave.
The truth is, roof damage doesn’t always
announce itself with a dramatic leak or
fallen shingle. Small issues like loose
flashing, worn-out underlayment, or
missing granules can quietly worsen over
time. Left unchecked, these seemingly
minor problems can lead to serious
consequences, including hidden water
damage, mold growth, reduced energy
efficiency, and even structural rot.
At WeatherTek Home Exteriors, we
believe that prevention is always more
affordable than repair. That’s why we’re
committed to helping Maryland
homeowners identify warning signs early—before costly damage sets in. Whether
you're dealing with the aftermath of a storm or simply unsure about your roof’s condition, our expert team is here to provide honest evaluations and proactive solutions you can trust.
Ignoring early signs of roof damage can lead to serious problems like mold, structural issues, and skyrocketing repair costs. At WeatherTek Home Exteriors, we’re here to help you spot the red flags before it's too late.
Here are the Top 5 Signs that it's time to consider a new roof, especially if you're living in Maryland's unpredictable climate.
1. Missing, Cracked, or Curling Shingles
If your roof’s shingles are visibly cracked, curled at the edges, or missing altogether, it’s a sign your roof has aged out of its protective role. Damaged shingles allow water to seep into the decking below, leading to wood rot, mold, and ceiling leaks.
❗️Pro Tip: After a heavy storm, walk your property and check for shingle pieces in your gutters or yard.
2. Water Leaks or Stains in the Attic or Ceiling
Have you noticed a brown or yellowish stain spreading across your ceiling? Or worse—water dripping indoors during a rainstorm? These are more than just cosmetic issues—they’re clear warning signs that your roof is failing to do its most important job: keeping water out.
When moisture penetrates your roofing
system, it can silently seep into your
attic, insulation, and drywall, causing rot
in your wood framing, deterioration of
insulation, and even short-circuiting
electrical systems hidden behind your
walls. Over time, this moisture buildup
can lead to mold growth, which isn’t just
a health hazard—it can be incredibly
expensive to remediate.
Even a small leak can spiral into
thousands of dollars in damage if left
unaddressed.
That’s why at WeatherTek Home Exteriors, we always say: if you see a stain, it’s time to inspect. Acting quickly can prevent minor roof issues from turning into full-blown structural emergencies.

3. Moss, Algae, or Mold Growth
At first glance, green moss patches or dark streaks of algae on your roof might seem like nothing more than a cosmetic issue but don’t be fooled. Organic growth is a sign that your roof is retaining excess moisture, and that can spell serious trouble over time.
Moss acts like a sponge, holding water against your shingles and preventing them from drying properly. This trapped moisture can break down the protective granules on asphalt shingles, making them brittle and less effective. Algae, often seen as black or green streaks, feeds off the limestone in your shingles and weakens them from the inside out. And if mold starts forming, it can quickly spread beneath the roofline, threatening not only your roof’s integrity but also your home’s indoor air quality. If you see green patches or dark streaks, your roof may be retaining water and nearing the end of its life.
These issues are especially common in shaded areas of the roof, where sunlight doesn’t reach and moisture lingers after rain or humidity. Left untreated, moss and algae can lead to soft spots in your roof decking, shingle lifting, leaks, and even premature roof failure.
4. Your Roof is 15-20+ Years Old
Most asphalt shingle roofs have a lifespan of 15–25 years. Even if your roof looks fine from the ground, its underlying layers may be worn, brittle, or poorly ventilated.

5. Spiking Energy Bills
Have your cooling or heating bills jumped recently? A poorly functioning roof can cause energy to escape through worn-out shingles, damaged underlayment, or failing ventilation systems.
A new, energy-efficient roof can reduce your bills and increase your home's comfort year-round.
