Why is My Metal Roof Leaking?

emergency-roof-repairMetal roofing provides unique durability, sustainability, and security for your home or business. However, even this strong substance has leaks. While these problems rarely lead to emergency roof repair, knowing how to identify and fix roof leaks will help you protect your home. What are some of the most common reasons for metal roof leaks?

Roofing Screws

The vast majority of leaks for metal roofing results from roofing screws that are improperly driven. If you want to avoid late night emergency roof repair, be sure to hire a trained professional to install your roof. These leaks can result when a screw is underdriven, overdriven, or driven in at the wrong angle. This results in small leaks that can grow over time. Have a roof inspection if you suspect that you have a small leak.

Missing Sealants

Be sure that you install your roof with the correct roof sealant. Manufacturers recommend a sealant specifically designed for metal roofs. Some caulking types do not work well with metal roofs. Have an inspection to pinpoint any areas that might have missing sealant. Especially look at metal ridge caps, around roof transitions, counter flashing, pitch pans, and Z flashings.

Other Common Problems

Capillary draw occurs when water travels along two tightly joined metal pieces, leading to a leak. Water also gets trapped behind HVAC units. Watch for issues around stack flashings, or the “boot” around pipes jutting out from metal roofs. Over time sunshine degrades the boot, leading to leaking water. Rubber flashings can also deteriorate over time. While the metal roofing itself is not prone to leaking, be sure to have a roofing professional inspect your roof for these specific problems.
