Have you noticed shingle tabs or whole shingles flapping about in the wind? Seen missing shingles or exposed plywood after a big storm? Wondering if it’s time for a new roof or a simple repair will suffice? Let’s take a closer look!
A common sight after strong winds, these broken shingle tabs are an indication of poorly sealed shingles, the wind will pick up the corner of a shingle and tear it (and sometimes the surrounding shingles) away from the roof deck.
The poor sealing of the tar band underneath the shingle could be a sign of a defective product, we have encountered whole roofs that haven’t sealed correctly due to a defective tar band on the rear of the shingle.
It could also be a sign of a winter installation, common in new construction, the roofs are installed far below the recommended temperatures and never fully bond together.
If the shingles around the damage are sealed tight and not able to be lifted then simply replacing the damaged shingles will suffice to get your roof back in good shape, however, if the surrounding shingles are also lifting then you’re only one strong wind away from a serious risk of water penetration.
Although it’s feasible to use roofing cement to stick down each individual shingle tab, it’s a tedious and often expensive process, consult with your contractor and consider replacing the section of defective shingles with a superior product.
