Mistakes are uncommon, especially in the roofing industry. From hiring the wrong contractors to a roofing repair task done wrong, a lot of things can happen when you’re trying to get a good roof above your head.

As someone who owns a home or business, it’s important that you know typical roofing errors. That way, you can get your money’s worth, avoid bigger and costly problems, and maximize the benefits of your roof.

What are the 8 Common Roofing Mistakes?

1. Going the DIY route instead of hiring a professional contractor

We’ve read tons of articles out there that encourage homeowners to install a new roof or perform a repair on their own. If you think you’ll be able to save money by doing-it-yourself, you’re absolutely mistaken.

Typical homeowners and business owners spend most of their days on other things. A roofing repair job is just not something they are well-versed in. Remember that roofers have spent years in training that they know everything about roofs – from the best materials to use to safety measures to different installation techniques.

2. Installing new shingles over old ones

Can you lay new roof shingles over old ones? The answer is yes, but not without risks. The only reason why homeowners choose to overlay shingles is to save money. Also, the installation process becomes easier since contractors do not have to go through the tedious step of removing old shingles.

Networkx.com outlines several reasons why an overlay is not advisable:

  • Old, curled shingles show themselves through the new layer.
  • Multiple layers of shingles add weight to your roofing.
  • An overlay masks problems which prevent a prompt roofing repair.
  • Imagine dealing with a 2-layer tear-off in the future!

3. Lack of a preventive maintenance plan

Just because you’re not a professional contractor does not mean you shouldn’t take simple steps to care for your roof. In our article on preventive maintenance, we mentioned 5 roofing tasks you can do regularly.

These tasks include the following:

  • Trim tree branches that touch the surface of your roof.
  • Keep your gutters clear of debris. Clogged gutters prevent proper drainage of rain water.
  • Look for signs of roof damage inside and outside your home or building.
  • Make sure to report any signs of damage to your contractor that you note.

Preventive maintenance saves you from a lot of hassle and expensive repairs.

4. Re-using roof flashing

If you don’t know what a roof flashing is, it’s the sheet of metal that prevents water from entering your home. It diverts water away from your roof to your gutter system.

A lot of homeowners assume that it is safe to reuse their flashing when replacing their roofs. There are those who claim that they have done this throughout their lives and haven’t experienced any problems.

Remember that an old piece of flashing isn’t as effective and long-lasting as the newly installed roofing material. It’s best to replace all roofing components when getting a new roofing to make sure that your home is fully protected.

5. Using nails incorrectly

A few important things boost the lifespan of your roof. One of these includes the proper use of nails. Some roofing repair contractors are in a hurry that they use too few nails to secure the roofing shingles.

Unscrupulous contractors do not also know the right nail placement. The ideal number of nails is 4 to 6. Most experts recommend 6 to ensure that your shingles are secured. A roofing contractor should also drive each nail through the nailing strip. Failure to do so will result in leaks.

6. Insufficient attic ventilation

Attics that are poorly ventilated damage residential roofs. This is a fact that most people are completely unaware of. Professional contractors should always make sure to inspect attics and ventilation systems.

If not, poor ventilation cause problems especially when temperatures get too high during the summer. Moisture starts to build up from the decking and damage your shingles. The right roofers know that the temperature inside your home or building should be close to the temperature outside.

7. Putting off important repairs

Do not put off a roofing repair to another time, no matter how simple or menial it is. Procrastination has many serious consequences. By delaying, you allow the damage on your roof to get bigger. A lot of people end up dealing with a roof replacement because they failed to contact their roofer to perform a minor repair task.

Put in mind that roofing issues don’t go away on their own. They get bigger as time passes by. Save your roof by calling a trusted roofer once you notice signs of roof damage.

8. Hiring storm chasers

What are storm chasers and what are they up to? Storm chasers are fly-by-night contractors that show up after a storm and insist that you hire them for your roofing repair needs. Stay away from these scams. Make an informed choice and follow these tips by the Better Business Bureau:

  • Steer clear of contractors that ask you to pay them in advance.
  • Ask for multiple written estimates (at least 3) from prospective roofers.
  • Pay through credit card or debit card so you can track your payment.
  • Get a copy of their license and insurance.
  • Ask for their complete physical address and pay them a visit.


These are the 8 common mistakes that you can avoid. While you can prevent problems on your end as someone who owns a house or building, you need help from trained professionals to give you peace of mind.
