The answer to 'missing architectural shingles' is that missing or damaged shingles are a common roofing problem that requires prompt attention. Architectural shingles can go missing for several reasons, such as high winds, hail damage, improper installation, or simply reaching the end of their lifespan. Missing shingles leave your roof vulnerable to leaks, water damage, and further deterioration.
If you notice missing shingles, it's important to inspect your roof thoroughly and replace any damaged or missing shingles as soon as possible. Depending on the extent of the issue, this may be a DIY project for homeowners with some roofing experience, but larger or more complex repairs are best left to professional roofers.
