The True Cost of a Bad Roof Repair: How to Avoid Expensive Mistakes

The only thing worse than needing your roof replaced or repaired is if it's done poorly.

If you've ever had a bad roof repair, you probably know how frustrating and costly it can be. A bad repair job can lead to leaks, water damage, and even structural damage to your home.

And it can range from a few hundred dollars to over $10,000 in additional costs.

But the true cost of a bad roof repair goes beyond just the initial expense. It can also impact your home's value and lead to higher insurance premiums.

So, how can you avoid making expensive mistakes when it comes to repairing your roof?

Let's explore the true cost of a bad roof repair. We'll also give you tips on how to avoid making costly mistakes.

Find out what signs to look out for on your roof. Then, learn how to prevent bad roofing jobs from impacting your home's longevity.

Your Roof’s Appearance

Signs of bad roof repair as seen in roof's appearance.

Many bad roofing jobs can be easily spotted, sometimes even from the ground. If the roof looks “off,” it probably has some issues from the repair.

There are a few ways you can tell if your roof replacement or repair was done inadequately.

Fortunately, appearance issues can usually be spotted early. So don't be afraid to do a roof inspection before the project is completed.

Missing or Damaged Roof Materials

Missing or damaged roof materials are a sign of bad roof repair.

Depending on the material of your roof, you may notice some irregularities in its appearance.

Sometimes, these irregularities will not show until after a large storm. Then, you'll notice the material flaking or going missing completely.

After your roof has been repaired, inspect it yourself to ensure no materials are missing, damaged, or improperly laid.

This is a common sign of poor roof repair. And while shingles can often be replaced in small batches, the severity of the original work could result in up to $5,000 or more in additional repairs.

Water Stains

Water stains are a sign of bad roof repair.

You may notice dark spots or stains on your roof, which is an early sign of potential leaking.

Inspect your attic for signs of a leaky roof if you notice these water stains.

Isolated leaks can sometimes be fixed for a fairly low cost. But if the damage is extensive, a roof leak repair could cost you thousands in additional repairs.


Inconsistent appearance of roofing materials is a sign of bad roof repair.

If you notice that your roof doesn't seem uniform, this is an early sign of a bad roofing job.

Your roofing materials should look consistent across your roof, as this provides maximum protection and durability.

If you notice glaring irregularities in your roof's pattern, inspect your attic for leaks. Then, get it fixed as soon as possible to avoid major damage.

Inconsistency is a sign of “lazy roofing,” meaning your roofer is cutting corners. And it could cost you up to $1,000 or more in additional repairs.

Your Roof's Structure

It is equally important to test the structure of your roof with its appearance. Your roof may look good, but that doesn't mean you've avoided potential risks of future damages.

There are a few signs to look for to ensure your roof structure is sound.

Hardware Issues

Hardware issues are a sign of bad roof repair.

To make your roof watertight, you'll need more than just shingles. Ensuring the proper hardware has been used to repair your roof is crucial to its longevity.

The flashing should be properly installed and caulked. Also, there are different types of roofs. And each roof may require a different type of roofing material, such as nails.

Choosing the wrong size, spacing too far, or nailing shingles too low will cause leaks. It may also cause torn or dislodged shingles or materials in a large storm.

If the wrong nails or attachments are used, the average cost can be anywhere from $1,000 to $12,000 in repairs.

Drip Edge

Drip edge is essential in roof repair jobs.

All roofs require a drip edge, and if you don’t have one, you could experience mold, rot, soil erosion along your foundation, staining, or even basement flooding. This metal sheet protects the board under the edge of your roof, called the fascia, from water damage. The second your repairs are complete, check for the drip edge immediately to avoid extensive and expensive damages.

Your roof needs an underlayment to waterproof your roof. This layer of paper material lies beneath your shingles or roofing material to protect you from water and storm damage.

A missing or damaged underlay will not only lead to leaks. It could also quickly shorten the lifespan of your roof. And the roof repair cost can be anywhere from $5,000 to $10,000.

Red Flags in the Contractor

There are certain tell-tale signs of a potentially poor roofing job from your contractor.

Here are a few things to look for when hiring professional roofing services. These will help you avoid bad repairs and expensive roof repair costs.


Any contractor worth their salt will thoroughly inspect and discuss the structures on your roof, such as chimneys or skylights. They will also inspect the attic or underside of your roof before any quotes are given. 

If your contractor doesn’t thoroughly evaluate your roof, it’s time to try someone else. You want a roofer that understands your home, needs, and is highly skilled. They should also be able to answer all of your questions and explain the what and why of the project.

Paperwork and Certifications

You should check up on your roofer, regardless of the size of the job.

Reliable contractors will readily show you their certifications and insurance information. Many licensed roofing contractors carry copies when on the field.

These documents are necessary to obtain a permit. They also shouldn't be a struggle to get from a professional roofing company.

Avoid Major Damage: A Preventative Maintenance Guide

Approach your roof repair proactively to avoid severe damage. There are three things you can do to avoid further repairs or replacement.

  1. Hire a reputable roofing contractor to assess your roof. Do your research and find a reputable roofing contractor to assess your roof. You should have regular maintenance done once a year. But if you suspect there is a problem, seek consultation right away.
  2. Continue having regular inspections to stay on top of potential damages. Your roof protects you and your home from all the elements. So, it's important to stay on top of its status. Inspect your attic and roof regularly, or hire contractors to assess it for you. This ensures that any new damages are caught well before they start costing you money.
  3. Don't DIY your roof repair. Unless you're an experienced roofer, don't repair your roof yourself. Not only is it dangerous, but it could lead to lasting issues that require expensive repairs.
