The roof is an integral part of any building. It provides protection from harsh weather conditions, insulates your home, and makes occupants comfortable. However, despite regular maintenance, the exposed nature of roofing systems makes them prone to damage. Common roofing issues facing homeowners include missing shingles, faulty gutters, leaks caused by extreme weather conditions, falling branches, and normal wear and tear. If these issues characterize your roof, you should consider repairing or renovating it. Hiring a roofing and home construction company can solve your problems regardless of the situation. However, you should be wary of the following roofing mistakes.

1. Hiring the Wrong Contractor

Most homeowners get everything wrong by choosing the wrong contractor for their roof replacement or renovation project. The success of roof renovation highly depends on the professionals assigned to the task. You should avoid contractors who are not certified or licensed to conduct home improvement projects. Good roofing contractors should provide the following:

  • Provide proof of certification
  • Show previous projects to demonstrate their experience and expertise in different roof renovation projects.
  • Conduct a thorough inspection to identify the underlying problems
  • Quote reasonable pricing

You shouldn’t hire contractors without checking their proof of credentials.

2.  Faulty Shingle Placement

Shingles play an important role in protecting your roof from weather damage. However, if they are positioned incorrectly, they won’t protect your roof from deteriorating. Shingles should be properly aligned to protect your roof. This means it shouldn’t have gaps or uneven areas. As such, contractors should ensure that shingles align and any gaps are filled during renovation.

As a homeowner, you should remain on-site to ensure that shingle placement is done correctly. Homeowners without knowledge of shingle placement often get lied to by contractors who quickly leave after doing shoddy work. While this might seem like a small mistake, it can exacerbate roof damage, necessitating yearly replacements.

3.  Choosing Cheap Roofing Materials

Choosing cheap roof replacement material is another common mistake made by homeowners. While saving a few bucks during renovation is a good idea, you’ll spend a lot in the long run. Faulty roofs made from cheap and inferior materials always give in to weathering, start leaking, and deteriorate faster.

Cheap and poor-quality roofing materials are vulnerable and prone to damage. If you choose cheap materials over quality, don’t be surprised by cracks and leaks after a few years. Note that roof damage exposes the entire building to damage. Spending more on quality and long-lasting materials is prudent.

4.      Improper Flashing

Flashing is an important protective shield used to ensure that water doesn’t penetrate your slates, shingles, and other roofing materials. They are typically installed in areas with frequent water runoff, such as chimneys, gutters, and vents. Flashings are also installed in parts with an underlayment that is vulnerable to water, such as front walls and edges.

Other roofing mistakes? A common mistake contractors make is failing to align roof flashing or using poor-quality materials. These errors lead to inadequate roof waterproofing and allow moisture seepage through joints. As a result, your roof will start leaking and cause structural damage.


While DIY home improvement projects are undoubtedly fun, you should hire professionals for important projects such as roof replacement or renovation. Working with experts eliminates the risks of these grave roofing mistakes that can necessitate expensive future repairs.
