Let’s be honest; replacing your roof isn’t exactly something you do for fun. It’s a big investment in your home’s safety, comfort, and value. That’s why it stings even more when the job isn’t done right. And unfortunately, we’ve seen it happen more times than we’d like to admit, especially right here in Pasadena.
At Rescue Roofing Construction, we believe you deserve roofing done right the first time. So we’re breaking down how to spot a bad roofing job before it becomes a big headache (and an even bigger expense). Whether you’ve recently had your roof replaced or are planning one soon, here’s what you need to watch for.
1. The Roof Looks… Off
Let’s start with the obvious. A newly installed roof should look neat, uniform, and solid from every angle. If yours has dips, bumps, mismatched shingles, or a wavy appearance, that’s a red flag waving at full mast.
Here’s what to look for:
- Shingles that don’t line up evenly
- Sections that look like different materials or colors were mixed in
- Curves or sagging in the roofline
This isn’t just an eyesore; it could mean the shingles were installed incorrectly or the decking underneath wasn’t replaced when it should’ve been. That can lead to leaks and long-term structural damage. And nobody in Pasadena wants to deal with that when the next rain rolls in.
2. Leaks After the First Rain
Pasadena might be all sunshine most of the year, but when it rains, it pours; and a new roof should be able to handle it. If you’re seeing water spots, dripping, or even just that musty smell after a storm, you may be dealing with the aftermath of a bad roofing job.
Now, mistakes happen. Even great installers can miss a nail or a flashing seam. But the real sign of trouble is how your roofer responds. A reputable company will be back out promptly to make it right. Are you being ghosted after calling about a leak? That’s not just poor service; it’s a sign the job wasn’t done right to begin with.
3. Critical Roof Components Were Skipped
A quality roof is like a well-made sandwich. Sure, the bread (your shingles) matters, but skip the good stuff inside, and the whole thing falls apart.
Sadly, one of the most common signs of a bad roofing job is when a contractor cuts corners by skipping essential components. That might include:
- Drip edges to guide water away from your fascia
- Underlayment for extra moisture protection
- Ventilation systems to prevent trapped heat and moisture
- Flashing around chimneys, skylights, and roof edges
- New pipe boots or vents (not reused old ones)
Sometimes this happens out of laziness. Other times, it’s a shady tactic to make the price seem lower up front. Either way, it’s bad news for your roof.
4. Your Attic Is an Oven (or a Freezer)
Roofing isn’t just about what you see from the street. If your attic feels like the inside of a sauna or a walk-in fridge, your roof ventilation might be to blame.
A good roofing contractor inspects and addresses attic ventilation during a replacement. Poor airflow causes hot air to cook your shingles in summer and moisture to build up in winter. Over time, that leads to cracking, curling, mold, and even sagging.
If your roofer never even looked in your attic? That’s a missed step, and a big one.
5. Rotten Decking Wasn’t Replaced
Here’s a classic case of “what you don’t see can hurt you.” Your roof decking is the wood layer under your shingles, and if it’s soft, rotted, or moldy, it must be replaced before new shingles go on.
A bad roofing job skips this step to save time or money, and the result is a roof that sags, leaks, and may not even pass inspection. A responsible roofer (like us!) won’t know how much decking needs replacement until the old roof is off, but they should communicate clearly with you about it and handle it the right way.
6. Flashing and Vents Were Reused
This one might seem minor, but it’s a common trick used by low-quality contractors. Flashing is the thin metal that protects vulnerable joints on your roof, and vents are your roof’s breathing system.
If these are reused instead of replaced, you’re basically sealing your new roof with worn-out parts; and that defeats the whole purpose of investing in a replacement. In many areas, building codes often require new flashing for a reason: it keeps your roof watertight and working properly.
7. No Paperwork, No Warranty, No Peace of Mind
Let’s say the roof looks good, and it hasn’t leaked (yet). But your contractor didn’t give you a written warranty. Or a detailed estimate. Or a breakdown of materials. Or anything, really.
That’s a problem.
Without documentation, you’re out of luck if something goes wrong later. A great roofing company should always provide:
- A written, fully-backed workmanship warranty
- Manufacturer warranty information
- A clear, detailed estimate (with no sneaky surprises)
- Proof of licensing and insurance
If you’re stuck chasing paperwork after the job’s done, there’s a good chance the work wasn’t done to the standard it should’ve been.
