Commercial metal roofs are known for their durability and longevity. However, even the best roofs can have hidden issues that can lead to costly repairs if not addressed. This blog will uncover the top five hidden problems in commercial metal roof repair in Austin and how they can be detected and fixed.
1. Corrosion Underneath the Surface
Corrosion is a significant problem that often lurks below the surface of a metal roof. It can be caused by moisture trapped under the roof’s protective coating. Over time, this can weaken the metal, leading to leaks and structural damage.
How to Detect It: Look for rust spots or stains on the roof. Corrosion might also cause the metal to look discolored or pitted. Regular inspections by a professional can help catch corrosion before it becomes severe.
How to Fix It: Corroded areas should be cleaned thoroughly and then treated with a rust-inhibiting primer. In some cases, the affected sections may need to be replaced.
2. Improper Installation of Flashing
Flashing is a crucial part of a metal roof system. It helps to seal joints and prevent water from seeping in. Improper installation of flashing can lead to leaks and water damage.
How to Detect It: Check around roof penetrations, such as vents and chimneys. Look for gaps, loose flashing, or signs of water damage inside the building.
How to Fix It: Improperly installed flashing should be replaced or reinstalled correctly. This may involve removing the old flashing, cleaning the area, and installing new, properly fitted flashing.
3. Blocked Roof Drains and Gutters
Blocked roof drains and gutters can cause water to pool on the roof, leading to potential leaks and structural damage. This is a common issue in commercial buildings with flat or low-slope metal roofs.
How to Detect It: Inspect gutters and drains for debris or blockages. Check for standing water on the roof after a rainstorm.
How to Fix It: Regular cleaning of gutters and drains is essential. Ensure that all debris is removed and that water flows freely away from the roof.
4. Seam Failure
Metal roof panels are joined together with seams. These seams can be vulnerable to failure, especially if they aren’t properly sealed or if the roof has experienced significant movement or stress.
How to Detect It: Look for gaps or openings along the seams. Water stains or leaks inside the building can also indicate seam issues.
How to Fix It: Seam failure can often be fixed by resealing the seams with a high-quality sealant. In some cases, damaged sections of the roof may need to be replaced.
5. Thermal Movement Issues
Metal roofs expand and contract with temperature changes. If the roof system isn’t designed to accommodate this thermal movement, it can lead to stress and damage over time.
How to Detect It: Look for signs of warping or buckling in the metal panels. Check for cracks or gaps that have appeared due to thermal movement.
How to Fix It: Proper installation techniques, such as allowing for expansion and contraction, can help manage thermal movement. If issues are already present, it may be necessary to adjust or replace parts of the roof to accommodate movement.
Final Words
Commercial metal roofs are a reliable choice for many businesses, but they’re not immune to issues. From corrosion and flashing problems to blocked drains and seam failures, understanding these hidden issues can help you maintain the integrity of your roof. Regular inspections and timely roofing repairs in Austin are key to extending the life of your roof.
