Have you ever stepped outside after a wind storm and found a missing roof shingle sitting in your yard? Discovering roof damage can feel concerning, especially if you worry that a missing shingle could allow water into your attic.
Understanding how shingles protect your roof can help you make informed decisions about repairs. Knowing the right steps to take after wind damage can also help you protect your home.
Ultimately, repairing missing roof shingles as soon as possible can help prevent leaks, limit further damage, and extend the lifespan of your roofing system.
Why Are Shingles Important?
A standard residential roof is designed in layers. Rafters and insulation sit beneath layers of plywood called “decking.” The decking then supports an ice and water barrier, underlayment, and shingles. Shingles also include multiple layers that overlap in a staggered pattern. When one shingle gets removed, another layer of shingles usually remains visible.
Shingles create the outermost barrier on your roof, protecting the structure from ice, rain, snow, and other weather elements. Without shingles, water and ice would regularly reach the layers underneath. This exposure could cause rot, ongoing leaks, and structural damage. Shingles overlap to help prevent water from penetrating your roofing system. A single shingle layer may not provide enough protection for the underlayment and materials beneath it, while multiple layers help improve defense against the elements.
Will One Missing Shingle Cause a Leak?
When wind or weather rips a shingle from your roof, another shingle layer usually remains underneath. Rain and snowfall can collect on this exposed layer, potentially leading to a slow leak. This risk increases if the missing shingle exposes the seams between two shingles.
If the damaged area sits in a roof valley or low point, the uneven surface can collect debris. Twigs and organic material may build up around the damaged area, trapping moisture and creating a weak spot.
In other words, one missing shingle may cause a leak, but not because it exposes the bare roof deck underneath. Instead, water can slowly work its way through small openings over time, causing gradual damage to your roofing system.
When Do You Need Roof Shingles Repair?
If your roof has missing shingles, this could indicate that your roofing materials have started to deteriorate. Newly installed shingles and shingles within their expected service life should not easily tear away from your roof. Older shingles and shingles installed incorrectly face a higher risk of this type of damage.
Missing shingles can also signal that your roof needs repairs. Contact a roofing contractor for a professional evaluation. If the damage remains limited, your contractor may recommend replacing the missing shingles. However, if the damage appears extensive, your contractor may recommend a complete roof replacement. To find out whether your roof needs to be replaced, contact Ainger Roofing for a consultation and evaluation of your roof.
