Roof condition plays a major role in the success of a self-storage property. Leaks will doom any operation, but ensuring this critical component remains well-maintained will save you money and keep tenants happy. As a roof system ages, it takes more work to preserve its integrity; but a proactive approach will minimize repairs and customer complaints.

What you need is a solid maintenance program that’ll sustain roof life and help you avoid expense and liability. Self-storage buildings can have various types of roofs including asphalt shingles, membranes, metal and built-up. With proper inspection and care, these systems can last for decades.

The Inspection

Newer self-storage roof systems should be inspected annually to capture condition documentation and remove debris. As a roof ages or leaks begin to occur, the schedule should increase to every six months. An examination is also warranted after any snow, wind or hail that may have caused damage. This is especially true if there are trees on the property, as the leaves can clog gutters or drains. Each roof is different and has its own specific needs, but a well-defined, timely inspection program will keep it watertight for decades.

Because most units on a self-storage property are usually rented, leaving the facility operator with no access, it can sometimes be difficult to detect leaks. That said, check any vacant units immediately following a significant rain. This opportunity to find unreported leaks may yield surprising results and can help alleviate complaints from customers down the road. When a leak is identified, make or arrange repairs as soon as possible.

Always keep records of your current roof condition, including photos. Often, issues will reoccur in the same areas of the system. When pursuing a leak, documentation can dramatically shorten the time it takes to find it.

Potential Roof Failures

A self-storage roof can experience many kinds of failure. Below are the more common issues that can be identified during inspection and fixed before they become larger problems.

Prevention and Cure

Ongoing roof inspections will help identify the above failures and keep your self-storage repair costs to a minimum. Many tasks such as cleaning gutters, trimming trees, caulking and removing snow are relatively simple and cheap, but the long-term benefits are huge. Larger failures such as ponding water and rust can be more expensive and require a roofing professional. Still, addressing issues quickly will help you eliminate the need for replacement.

Metal roofs with early signs of rust can be treated with an elastomeric coating to restore the system. This use of a primer and built-in rust inhibitor will eliminate future problems and prolong the useful life of the existing metal panels at a fraction of the cost of replacement. However, once rust becomes embedded into the metal, replacement will be the only option.

Ponding water deteriorates a roof system quicker than any other failure. Excessive moisture that remains on a roof for longer than 48 hours will accumulate debris and accelerate the deterioration process of flat roofs and rust on metal roofs. The installation of drains will be an immediate expense, but it’ll pay long-term benefits by extending your roof life.

Rust caused by ponding water

Once a self-storage roof is beyond repair, an overlay system is a good way to avoid exposing tenants’ contents. There are several installation options that can minimize disruption to your operation and provide energy-efficiency at a fraction of what it would cost to do a complete tear-off and replacement.
