Roof Body

The largest part of your roof is called the roof body, and it’s the one most exposed to the elements. Signs of a leak in your roof body include:

Rust Damage

Rust on a metal roof could indicate your roof’s finish is worn down. While the appearance of rust may not automatically equate to a leak, it’s essential to deal with the issue before it spreads. If left unchecked, rust can deteriorate the metal until holes form.

Loose, Missing, or Overly Tightened Screws

Loose or missing screws are an open opportunity for water to enter your roof. Overly tightened screws can lead to warping, which can also allow water in. Checking for these is a relatively simple, though time-consuming task. Roofing repairs are easy when spotted early.

Punctures from Weather of Foreign Objects

An apparent cause of a leak may be an actual puncture or hole in your metal roof from inclement weather or foreign objects. Even small dents can eventually lead to more significant problems as pooled water gets trapped in them, deteriorating your roof.

Panel Shifting

Improper metal roof installation may lead to panel shifting or even lifting, allowing water to get under your roof.

Roof Penetrations

Roof penetrations are areas where your roof’s metal has been cut or punctured to install other features, such as chimneys, ceiling vents, skylights, and air conditioning units. The following issues can cause leaks in roof penetrations:

Cracked Flashing Seals and or Decayed Seals

There are many reasons your flashing seals may crack. Wear and tear are the most common cause of broken flashing seals, though poor installation can also be a culprit.

Trim Gaps

Gaps in your metal roof’s trim are an open invitation to water. Causes for gaps vary from improper installation, foreign object damage, or general wear and tear.

Termination and Transition Points

Termination and transition points are areas where your metal roof ends or meets with other sections of your roofing. These points have a higher prevalence of leaks than most roof areas. Some issues to check for include:

Loose Trim

Loose trim can lead to trim gaps, which can cause significant leaks in metal roofing. Make sure to routinely check your trim to ensure it is properly fastened, with no loose pieces.

Gutter or Flashing Damage

Damage to your gutters can cause water to pool up and wear down your roof and its seals. It’s crucial, especially with a metal roof, to ensure proper water runoff. Flashing also helps protect your roof in areas of high water accumulation. Any damage to your flashing increases the chances of water entering your home.

Missing or Loose Caps

Just like loose trim or trim gaps, missing or loose ridge caps can leave your home susceptible to water damage. Ridge caps are vital as they’re the first line of defense on major seams in your roof.

What to Do If You Suspect a Leak in Your Metal Roof

If you suspect there’s a leak in your metal roof, it’s vital to get it taken care of as soon as possible. Water damage can cause problems with the structural integrity of your home. Moisture can also lead to mold buildup and affect your home’s air quality and, in turn, your health.
