Common Roofing Mistakes Homeowners Make & How to Avoid Them

Your roof is one of the most important parts of your home and a large investment. When you replace your roof, you want to make sure the job is done right. The wrong materials or improper installation can lead to costly mistakes and premature roof failure.  

If you live in Fort Atkinson or the surrounding area, understanding these common roofing mistakes can help you protect your home from Wisconsin’s harsh winters, heavy rains, and summer storms.

7 Common Roofing Mistakes Homeowners Make

1. Ignoring Small Roof Problems

A small leak, missing shingle, or damaged flashing might seem like no big deal. However, these small problems can quickly turn into major repairs if ignored.

2.. Attempting DIY Roof Repairs

There are some repairs that are just better left for the professionals. Professionals have the training and equipment to complete the job safely and properly.  It can be dangerous to climb onto your roof without the proper equipment, and you don’t know what you don’t know. You may unknowingly make a mistake while attempting a DIY roof repair. Often, homeowners who try DIY fixes themselves find that they installed shingles incorrectly, used the wrong materials, or missed signs of underlying damage.

3. Choosing the Cheapest Roof Bid

Like everything in life, you get what you pay for. Choosing the lowest bid can sometimes lead to shortcuts, low-quality materials, and poor workmanship. For example, some contractors cheap out on the underlying materials that you don’t see to maximize their profit. By using improper materials, this may actually void the manufacturers’ roof warranties.  Make sure quality materials are used for the entire roofing system. Other ways to cut corners include using inferior shingles, skipping the underlayment, improper installation, or rushed installation. All of these shortcuts can significantly shorten the lifespan of your roof.

4. Contracting a Storm Chaser

When hiring a roofing contractor, it is so important to hire a local contractor who answers their phone and stands by their work. After a storm, it is common for tons of out-of-state roofing companies to target neighborhoods with door knocking, mailers, etc. If you hire one of these storm chasers, you run the risk that they will disappear and not be available if issues arise in the future.

5. Neglecting Ventilation

Proper roof ventilation and insulation is critical for maintaining the health of your roofing system. Without adequate airflow, heat and moisture can become trapped in your attic. In Wisconsin homes, poor ventilation can lead to ice dams during winter, higher energy bills, premature shingle deterioration, and mold and moisture problems.

6. Skipping Roof Maintenance

Many homeowners fail to regularly maintain and inspect their roof. Don’t wait until your gutters clog to clean them. When gutters become clogged with leaves, debris, or ice, water cannot properly drain away from the roof. This can cause water to back up under shingles and damage the roof structure. Don’t neglect your roof and figure everything is fine until you see a bigger problem like a leak. Unfortunately, by the time a leak appears, significant damage may already exist.

7. Waiting Too Long to Replace Your Roof

Eventually, every roof reaches the end of its lifespan. Most asphalt shingle roofs last 20–30 years, depending on installation quality and weather conditions. Waiting too long to replace an aging roof can lead to ongoing leaks, insulation damage, and interior repairs.

5 Tips to Avoid these Common Roof Mistakes

To avoid these common mistakes, keep these five tips in mind:

1. Be Proactive

If you notice warning signs that your roof may need to be repaired or replaced, schedule a roof inspection with a local roofing contractor.  If you catch a problem early, it may be simple repair and can save thousands of dollars.

2. Understand the Quote & Materials

When you get a roofing quote, make sure you understand what is included and what’s not included. At PK Contractors, we use the entire suite of CertainTeed products for our roofs. Our quotes may not be the lowest, but our workmanship will hold up and adhere to the CertainTeed Manufacturer’s warranty.

3. Hire Local & Do Your Homework

Look for a reputable contractor serving Fort Atkinson with strong reviews, proper licensing, and manufacturer certifications.

4. Prioritize Roof Maintenance

Roofing maintenance and roof-checks should be performed every fall and spring.

Seasonal maintenance includes:

• Clean your gutters & downspouts

• Remove leaves and debris from the roof

• Trim nearby trees & branches

• Cover vents & openings

• Watch for moss, algae, or ice dam buildup

• Inspect shingles for damage or missing pieces

• Check flashing around chimneys and vents

• Inspect structural elements

If you notice any damage or warning signs, contact a roofing professional for a roof inspection. It is far less costly to be proactive and fix small issues before they grow into larger, more costly problems.

5. Schedule a Professional Inspection

Routine inspections help identify issues before they become serious problems.

Have your roof inspected:

• After severe storms

• Every few years as preventative maintenance

• Before selling or buying a home

Regular inspections are especially important in areas like Fort Atkinson where winter weather and seasonal storms can take a toll on roofing systems.
