Common DIY Shingle Installation Mistakes

In general, DIY roofing projects are a bad idea, unless you’ve had experience working as a contractor. This is because first-time DIYers are more likely to make expensive mistakes that will end up costing them more in the long run. In most cases, it’s best to let certified roofers handle roof installations.  

Here are some of the common mistakes first-time DIYers make when installing roofing shingles: 

Forgetting to install the starter shingles first. As the name suggests, starter shingles should be installed first to prevent water from infiltrating your roof through gaps at the edge of your roof. The starter shingles should be aligned properly, while the asphalt shingles should overlap each other.  Otherwise, water can seep through the gaps. 

Not using enough nails. The shingle manufacturer should have included the recommended number of nails for each shingle, as well as the exact location for each nail. Conventional shingles usually need four nails on top of a narrow strip on their surface. 

Overdriving the nail. When using a hammer, the shaft should be driven into the shingle’s surface. However, it’s also important that the nail isn’t driven too far into the shingle. Otherwise, the nail might damage the mat or the foundation of the shingle. 

Given that even a tiny mistake can lead to costly problems with your roof, it’s best to let professional roofers handle roof installations and emergency roof repair. Don’t forget to vet a prospective contractor before hiring them. 

Here are some vetting tips to help you find a qualified roofer: 

• Hire local – To narrow down your options quickly, focus your search on contractors in your area. Hiring local contractors has its advantages. For starters, since they’re more familiar with the local climate and building codes, they can make better recommendations. 
• Check their certifications – Manufacturers such as GAF® vet contractors before they certify them, so in a sense they’ve done all the vetting work for you.
