What Are the Signs of a Bad Roofing Job?

Your roof is one of the most important parts of your home—it protects everything underneath it. So, when it comes time for repairs or a full replacement, you want the job done right. Unfortunately, not every roofing contractor delivers quality workmanship. A bad roofing job can lead to major headaches down the road, from leaks and water damage to costly repairs. But how can you tell if your roof was installed poorly? Here are some key signs to watch out for:

1. Uneven or Wavy Shingles

One of the most obvious red flags is the appearance of your shingles. A well-done roof will have straight, even lines and uniform shingle placement. If you notice shingles that look wavy, misaligned, or not properly secured, that’s a clear sign something went wrong during installation. Uneven shingles can lead to early wear and reduce your roof’s lifespan.

2. Missing Drip Edge

The drip edge is a piece of metal installed along the edge of your roof to direct water away from the fascia and into the gutters. It’s a small but critical component of a proper roofing system. If it’s missing, water can seep behind your shingles and cause wood rot, mold, and other damage. Many fly-by-night contractors skip this step to save time or money.

3. Improper Nailing

Shingles must be nailed correctly to stay secure and prevent leaks. If nails are overdriven, underdriven, or placed in the wrong location, the shingles can come loose or blow off in a storm. You may not notice this right away, but an inspection or a few wind gusts might reveal the issue.

4. Lack of Roof Ventilation

A good roofing system includes proper ventilation to allow air to circulate through your attic. Without it, heat and moisture can build up, leading to warped decking, mold growth, and decreased energy efficiency. If your contractor didn’t address ventilation, it’s a major oversight.

5. Leaks or Water Stains Shortly After Installation

If you notice water stains on your ceilings or walls not long after your new roof is installed, that’s a big red flag. New roofs should not leak. Any sign of moisture is usually a result of poor workmanship, improper flashing, or failure to seal roof penetrations like chimneys and vents.

6. No Underlayment

The underlayment is a protective layer installed between the roof deck and shingles. It acts as a backup barrier against water. Some shady contractors might skip it entirely to cut corners. Without it, your roof is far more vulnerable to leaks and deterioration.

7. Poor Cleanup or Messy Job Site

While this isn’t directly related to roof performance, a contractor who leaves behind debris, nails, and materials is often careless in their work overall. A clean job site usually reflects attention to detail.


What To Do If You Suspect a Bad Roofing Job

If you think your roof was installed poorly, contact a licensed, reputable roofing professional to inspect the work. Catching issues early can save you from bigger problems down the road. Don’t be afraid to ask questions, request photos, or get a second opinion. Your roof is too important to leave to chance.
