Let’s be honest: your roof is the classic “out of sight, out of mind” part of your home.
As long as water isn’t dripping into your living room, it’s easy to assume everything is fine up there. But here’s what we’ve learned after years of inspecting roofs across New Jersey and Pennsylvania: a roof rarely fails all at once. Failure is a slow, quiet process. A single cracked shingle, a small piece of loose flashing, or a minor gutter clog can seem insignificant.
But add one of our brutal New Jersey/Pennsylvania winters or a humid summer, and that tiny issue becomes a gateway for water. That water rots your roof decking, ruins your insulation, and creates a costly, stressful disaster.
A proactive roof inspection is the single best way to protect your home. It’s not a sales pitch; it’s a health check-up for your most important asset. As expert roofers, we see the same patterns over and over.
Here are the top 5 most common—and most dangerous—roof problems we find during our inspections.
1. Leaking or Damaged Flashing Inspection Problems
This is the number one culprit we find for active roof leaks.
What It Is: Flashing is the thin metal material installed anywhere your roof is penetrated or meets a vertical surface. Think of it as the “caulking” of your roofing system. You’ll find it around your chimney, in roof “valleys,” around skylights, and circling the vents for your plumbing and attic.
Why It’s a Problem: Flashing is the most vulnerable part of your roof. It’s often sealed with tar or caulk, which can dry out, crack, and pull away over time. The metal itself can rust, or a bad installer might have nailed it incorrectly, creating a perfect entry point for water. Because these are transition points, any water that gets under the flashing has a direct path into your home.
How We Find It: During an inspection, we don’t just glance at the flashing. We physically check the seals. We look for signs of rust, gaps, or any sections that have pulled away from the brick or siding. We also check for “nail pops,” where the nail has pushed up, breaking the shingle’s seal.
The Solution: Sometimes, the fix is as simple as applying new, high-grade sealant. In other cases, the old, rusted flashing needs to be completely removed and replaced. This is a surgical repair that requires an expert. A new, properly installed flashing system is the difference between a dry home and a recurring nightmare.
2. Missing, Cracked, or Curling Shingles Inspection Problems
This is the most visible problem we spot from the ground, but the extent of the damage is often hidden.
What It Is: Your asphalt shingles are your roof’s armor. They are a tough, flexible mat covered in waterproof asphalt and UV-blocking granules. But they don’t last forever.
- Curling Shingles: This happens when shingles get old. The edges curl up or down, making them look like a peeling sticker.
- Cracked Shingles: This is often caused by wind or impact damage.
- Missing Shingles: High winds can get underneath a poorly sealed or old shingle and rip it right off the roof.
Why It’s a Problem: A single missing shingle is like a missing scale on a suit of armor. It exposes the underlayment (and sometimes the wood decking) directly to the elements. A cracked or curling shingle is just as bad. It acts like a tiny funnel, collecting rainwater and guiding it under the surrounding shingles and down to the nail holes.
How We Find It: Our inspectors walk the roof and physically lift shingle tabs to check their flexibility and the strength of the sealant strip. A healthy shingle is pliable; an old shingle is brittle and will often crack with gentle pressure. We document every missing, cracked, and curled shingle we find.
The Solution: If the roof is relatively new and we only find a few damaged shingles, we can often perform a simple repair by replacing them. However, if the curling and cracking are widespread, it’s a sign that the entire roof is at the end of its life. This is when we discuss a full roof replacement using a high-quality system, like the GAF Timberline HDZ shingles, which are specifically designed to resist high winds and aging.
3. Clogged or Damaged Gutters
You might think gutters are a separate issue, but at Nailed It Roofing, we consider them a critical part of the roofing system.
What It Is: Your gutters have one job: catch all the water from your roof and move it safely away from your home’s foundation. But they fill up with leaves, pine needles, and shingle granules, creating a dense, heavy sludge.
Why It’s a Problem: When gutters clog, the water has nowhere to go but up.
- Water Backs Up: Rainwater will flow back under your shingles, rotting the edge of your roof decking (the fascia and soffit boards).
- Ice Dams: In a New Jersey or Pennsylvania winter, that trapped water freezes. This creates a heavy “ice dam” that can pry your shingles up, pull your gutters right off the house, and force melting snow into your attic.
- Foundation Damage: Water spilling over the sides erodes the soil around your home, leading to cracks in your foundation.
How We Find It: This one is easy. We physically check the gutters and downspouts for blockages and ensure they are still securely attached to the house. We also look for “tiger striping” (black streaks) on the gutter face, which is a sign of persistent overflowing. For a deep dive on gutter maintenance, this guide from This Old House is a great resource for homeowners.
The Solution: The immediate fix is a thorough gutter cleaning. If we find that the gutters are bent, sagging, or improperly pitched, we’ll recommend a repair or replacement to ensure your home is protected.
4. Poor Attic Ventilation
This is the “silent killer” of a roof. It’s a huge problem that you can’t see from the outside, and it can cut a roof’s lifespan in half.
What It Is: A healthy roofing system needs to breathe. It requires a balanced “intake” (at the soffits, or eaves) and “exhaust” (at the ridge, or peak). This airflow constantly circulates air through your attic. Poor ventilation means the air is trapped.
Why It’s a Problem: A-stagnant attic creates two different disasters in two different seasons.
- In the Summer: Trapped hot air can reach 150°F or more. This extreme heat literally bakes your shingles from the inside out, causing them to curl and fail decades before their time. It also forces your air conditioner to work overtime, costing you money.
- In the Winter: Warm, moist air from your living space (from cooking, showers, etc.) rises into the attic. If it can’t escape, that moisture condenses on the cold underside of your roof decking. This leads to mold, mildew, and rotted wood.
How We Find It: An inspection that doesn’t include the attic is incomplete. We go into the attic and look for the physical signs. Is there proper soffit and ridge ventilation? Is the insulation blocking the soffits? Do we see signs of mold or mildew on the wood? Is the decking soft or damp?
The Solution: Improving ventilation can involve installing a new ridge vent, clearing or installing soffit vents, or adding baffles to ensure insulation isn’t blocking airflow. As ENERGY STAR notes, proper ventilation and insulation work together to make your home more comfortable and efficient.
5. General Wear, Tear, and Old Age
Sometimes, the problem isn’t one specific failure—it’s that the entire system has simply reached the end of its service life.
What It Is: An asphalt shingle roof, even a good one, is designed to last 20-30 years. As it ages, the protective granules wear off, the asphalt becomes brittle, and the sealant bonds fail.
Why It’s a Problem: An old roof is a ticking time bomb. It’s not a question of if it will leak, but when. The shingles no longer offer effective protection, and the underlayment is likely in poor shape. Waiting for it to fail will always cost you more in interior water damage repairs than proactively replacing it.
How We Find It: The biggest clue is “granule loss.” We look in the gutters for what looks like coarse black sand—this is the “grit” from your shingles. A roof with significant granule loss has lost its primary layer of protection. We also look for widespread curling, “bald” spots, and signs of previous, low-quality patch jobs.
The Solution: At this point, repairs are just putting a band-aid on a system-wide failure. The only responsible solution is a full roof replacement. This is your opportunity to upgrade to a modern, integrated roofing system. As GAF Master Elite Contractors, we can install a full GAF roofing system with Timberline HDZ shingles. This not only solves the problem but gives you a lifetime-backed warranty for decades of total peace of mind.
A Roof’s Life in Doylestown, PA: Why Local Inspections Matter
The weather in New Jersey and Pennsylvania is uniquely tough on roofs. We don’t just get one extreme; we get all of them. We have humid, hot summers, heavy rain from coastal storms, and—most damaging of all—the relentless freeze-thaw cycle in winter.
When we inspect a historic home in Doylestown, PA, for example, we’re not just looking at the shingles. We’re looking at how decades of these weather cycles have impacted the home. Water gets into a small crack, freezes, expands, and turns that crack into a gap. This cycle, repeated hundreds of times, is what tears a roof apart.
Your local roofer needs to understand this. Our inspections are tailored to the specific challenges of our climate, ensuring we catch the problems that out-of-state “storm chasers” would miss.

FAQs from Nailed It Roofing
1. Q: What is the most common roof problem you find?
A: The most common problem we find during roof inspections is leaking or damaged flashing. Flashing is the metal material around chimneys, vents, and skylights. Its seals can crack, or the metal can rust, creating a direct path for water to enter your home.
2. Q: What do curling or cracked shingles mean?
A: Curling or cracked shingles are a sign that your roof is aging and becoming brittle. This condition compromises your roof’s waterproofing, as these shingles can no longer seal properly. They can act like funnels, guiding water under your roof and leading to leaks.
3. Q: How do clogged gutters cause roof damage?
A: Clogged gutters cause water to back up and overflow. This water can flow back under your shingles, rotting your roof decking and fascia boards. In winter, this trapped water freezes, creating heavy ice dams that can lift shingles and pull gutters away from the house.
4. Q: What is attic ventilation and why is it important for a roof?
A: Attic ventilation is a balanced system that allows air to flow through your attic. It’s critical for your roof’s lifespan. In summer, it exhausts extreme heat that can bake your shingles from below. In winter, it removes moist air that can cause condensation, mold, and wood rot.
5. Q: How can I tell if my roof is old and needs replacement?
A: The most common sign of an old roof is widespread granule loss. You’ll find what looks like black sand or grit in your gutters. Other signs include shingles that are curling, cracking, or “bald” (missing granules), indicating the roof is at the end of its life.
6. Q: What is the difference between a roof repair and a roof replacement?
A: A roof repair is appropriate when the damage is isolated to one area (like a few missing shingles) and the rest of the roof is still in good condition. A roof replacement is necessary when the damage is widespread or the entire roofing system is old and failing.
7. Q: Why is a roof inspection in the attic important?
A: An attic inspection is crucial because it helps the inspector find the true source of a leak. Water often travels along rafters and insulation, meaning the water stain on your ceiling may be many feet away from the actual hole in your roof.
8. Q: How does the weather in New Jersey and Pennsylvania damage roofs?
A: NJ and PA weather is especially tough due to the freeze-thaw cycle. Water gets into tiny cracks, then freezes and expands, forcing the cracks wider. This, combined with hot summers, high humidity, and coastal storms, accelerates a roof’s aging process.
9. Q: What is GAF Timberline HDZ?
A: GAF Timberline HDZ is a high-performance architectural shingle from GAF. It’s designed to be extremely durable, featuring LayerLock™ Technology for strength and a special nailing area that qualifies it for an industry-leading wind warranty with no maximum speed limit.
10. Q: Should I get on my roof to check for damage myself?
A: No, you should never get on your roof yourself. It is extremely dangerous. A roof can be slippery or have hidden structural damage. A professional, insured roofer has the required safety training and equipment to perform a thorough inspection safely.
