How Florida Homeowners Can Spot Poor Roofing Workmanship

A new roof is one of the biggest investments you'll make in your New Smyrna Beach home, and most homeowners assume that once the crew packs up and drives away, the job was done right. Unfortunately, that's not always the case. Poor roofing workmanship is more common than it should be, and in Florida's brutal climate — relentless UV exposure, high humidity, and the ever-present threat of hurricane-force winds — a flawed installation doesn't just look bad. It fails faster, leaks sooner, and can void your manufacturer's warranty before your first rainy season is over.

The good news is that many signs of bad workmanship are visible to an attentive homeowner, even from the ground. Knowing what to look for puts you in control, whether you're evaluating work that was just completed or inspecting a roof on a home you're thinking of buying. Here's what to watch for — and what you can do about it.

Uneven or Misaligned Shingles

Step back from your home and look at the roof from the street. The shingle courses — the horizontal rows — should run in perfectly straight, parallel lines from the eaves all the way to the ridge. If the rows look wavy, curved, or like they drift upward or downward as they cross the roof, that's a red flag.

Misalignment isn't just cosmetic. When shingles aren't properly staggered and lined up, their joints — the seams between individual shingles — can line up vertically instead of being offset. That creates a direct path for water to work its way through. In Florida, where heavy afternoon downpours are practically a daily event from June through September, even a small vulnerability like this can turn into a persistent leak within a season or two.

Also look for shingles that appear lifted, cupped at the edges, or lying flat in some spots and raised in others. Inconsistent nailing patterns are often the culprit: shingles that are under-nailed can lift in high winds, while over-driven nails can crack the shingle's mat and create weak points.

Exposed or Incorrectly Placed Nails

Roofing nails should be hidden. On a standard three-tab or architectural shingle roof, every nail is driven into the "nailing strip" — a designated zone on the shingle — and then covered completely by the shingle course above it. If you can see nail heads anywhere on your finished roof, that's a workmanship failure.

Exposed nails rust quickly in Florida's humidity, and each one is an entry point for water. Over time, the sealant around an exposed nail breaks down, the nail backs out slightly, and water wicks in beneath the shingle. What starts as a tiny drip in the attic can eventually rot the decking underneath.

Pay special attention to the cap shingles at the very top of the roof — exposed nails there are especially common with hurried work.

Improper or Missing Flashing

Flashing is the sheet-metal work installed wherever the roof surface meets a vertical surface — chimneys, walls, skylights, plumbing vents, and roof-to-wall transitions. It's also used in valleys where two roof planes meet. Done correctly, flashing directs water away from those vulnerable joints. Done poorly — or skipped entirely — it's one of the leading causes of roof leaks.

Watch for these specific flashing problems:

• Step flashing missing or replaced with caulk. Caulk alone is never an acceptable substitute for proper step flashing along a chimney or dormer wall. It cracks, shrinks, and fails, often within a year or two of installation.
• Valley flashing not properly overlapped. In open-metal valleys, the metal should extend well under both sides of the shingles. Inadequate overlap lets wind-driven rain push water uphill under the edge.
• Chimney flashing with gaps or lifting edges. Florida's thermal expansion and contraction cycles are severe — metal that isn't correctly secured and sealed will work itself loose.
• No drip edge at the eaves or rakes. Drip edge is required by Florida Building Code. Its absence means water runs behind the fascia and rots the wood over time.

If you see caulk where metal flashing should be, that's almost always a shortcut that will cost you later.

Poor Ridge Alignment and Ridge Cap Installation

The ridge — the very peak of your roof — should form a straight, level line from one end of the house to the other. A ridge that sags, bows, or shows a visible kink can indicate structural issues, improper decking, or simply careless installation.

The ridge cap shingles (or a ridge vent system) should be centered evenly on the peak, with consistent exposure and no gaps. Gaps in the ridge cap are a direct invitation for wind-driven rain to enter — and in Florida, wind-driven rain is something every roof has to handle year after year.

Other Workmanship Red Flags Worth Noting

• Debris under the shingles. Old roofing material left on the deck before new shingles were installed creates an uneven surface and can trap moisture.
• Inadequate ventilation. Improper attic ventilation is sometimes an installation oversight rather than a design flaw. Signs include blistering shingles or excessive heat buildup in the attic.
• Mismatched shingles. Different dye lots or even different product lines blended together signal that a contractor ran short of material and substituted rather than ordering properly.

What Recourse Do You Have?

If you suspect your roof was installed poorly, you have several avenues to pursue.

First, document everything. Take dated photographs of every defect you can see — from the ground and, if you can safely access it, from a ladder at the eave level. Write down the dates you first noticed each issue.

Second, review your contract and warranty. Most reputable roofing contractors provide a separate workmanship warranty (distinct from the manufacturer's material warranty). This is the document that governs defective installation claims. Read it carefully for the claims process and time limits.

Third, file a complaint if necessary. In Florida, roofing contractors are licensed through the Department of Business and Professional Regulation (DBPR). You can file a complaint against a licensed contractor's license if workmanship falls below the accepted standard of care. This creates an official record and can result in disciplinary action.

Finally, get an independent inspection. A qualified, unaffiliated roofer can document defects in writing, which is often essential if you need to pursue a legal remedy or negotiate with the original contractor.
