Did you know that there is a $56 billion roofing contractor market size in the United States? 

Replacing a roof can seem like a big project. If you haven’t done it before, you want to ensure that you get it right. If not, you could end up with a bad roof.

In the end, your budget may be squeezed. Keep reading for the top common roof replacement errors.

1. Poorly Installed Flashing

Flashing is a waterproofing material installed along roof edges and around roof penetrations. If it is not sealed correctly, water can pool in certain areas. This will keep water from infiltrating a roof system.

Flashing must be correctly sized. It must be bent to match the roof’s contours, sealed with a proper waterproofing sealant, and use a proper underlayment membrane beneath. 

2. Improperly Oriented Shingles

When attempting such a complex task, mistakes can be made. When shingles are not oriented correctly, it can lead to an uneven look for the entire roof and cause issues with water runoff.

Orientation should be double-checked while installing a new roof and regularly inspected afterward. It’s essential to ensure the shingles are being nailed onto the plywood at a consistent and parallel level using cheap materials.

3. Using Low-Quality Materials

The most common error made is using low-quality materials to save money. This often results in shingles that are inaccurate in size and have a shorter life span as they cannot withstand harsh weather conditions as effectively.

Make sure to use different roofing materials that are high quality. Do your research to find the most durable and reliable materials for the job, like roof rain diverter, and do not get fooled by materials that may seem cheaper at first glance.

4. Not Reviewing Contractors

Not reviewing contractors is one of the standard roof replacement errors, and homeowners should avoid it. It’s’ essential for homeowners to ensure that their contractor is appropriately trained, licensed, insured, and bonded before committing to any services.

Homeowners should make sure to request references from the contractor. Check those references to better understand the contractor’s past work. 

5. Not Measuring the Roof

When preparing to replace a roof, it is vital to accurately measure the top’s pitch, length, and width. Not counting the top correctly could lead to mistakes in ordering the proper size.

Homeowners should utilize a measuring tape and adequately measure the roof or hire a professional. Proper measurements can make the entire roof replacement process go much more smoothly.

6. Not Knowing Building Codes

Not familiarizing yourself with local building codes is one of the most common roof replacement errors that homeowners make. Without a proper understanding of the standards set by local building codes, you may end up spending more on a roof replacement than is necessary.

Do your research and ensure your roofer is familiar with and compliant with all relevant building codes. Never be afraid to ask questions and double-check your roofer’s work.
