What Do We Mean By Exposed Fasteners On The Roof?

Updated: Jan 25, 2023

For many of our home inspections in the Cincinnati and Dayton areas, we often comment on exposed fasteners on the roof.


Usually these fasteners are covered with a caulking or sealant and it is a common condition used by many roofers to complete their jobs.


But is it correct and what should we do about it?

We often see this done to fasten the last cap shingle or to secure flashings to the roof. In most cases, the roofers should have tried to cover the fasteners with the roofing material.




How to maintain the sealant


Although it is common to find this type of sealant on roof fasteners, eventually, the sun and environment will cause the sealant to deteriorate or degrade over time.

Annual Monitoring


Every year, the homeowner should have the sealed fasteners inspected.


This is to ensure that the sealant is still viable and doing its intended job. If the sealant fails, moisture will be able to intrude into the roof deck structure and can lead to future issues including mold and material rot.

Reapply as Needed


If the sealant has deteriorated, it should be reapplied by a qualified person to protect and ensure the longest possible life for your roof.

Exposed fasteners on a roof refer to the visible screws or nails that secure roofing panels or shingles to the structure. While this method is cost-effective and commonly used in metal roofing, it can pose potential risks like leaks and corrosion over time, especially if not properly maintained. Working with a reliable roofing contractor ensures that exposed fasteners are installed correctly and maintained to prevent future issues. They can also recommend alternative systems like hidden fasteners for improved durability and performance.
