Leaks around steel and ridge vents often occur due to several common issues. These vents are designed to allow air circulation and prevent moisture buildup in the attic, but their placement along the roof’s peak can create vulnerabilities if not installed or maintained properly. One frequent cause is improper sealing where the vent meets the steel roofing panels, allowing water to seep in. Over time, the sealant can degrade from exposure to sun and weather, or installation errors might leave gaps. Another cause can be damage to the vent itself, such as cracks or rust, or loose fasteners that compromise the vent’s attachment. To check for leaks safely, start by inspecting the inside of your attic during or right after a rainstorm, watching for water stains or damp spots near the ridge vent. From outside, look for any visible damage or areas where the vent flashing may have shifted. Make sure the vent seams look flush and sealed, especially around nail or screw holes.
For simple DIY checks, you can gently press around the vent’s flashing to see if it moves or seems loose, and carefully remove debris that might block proper sealing. However, given that working near a ridge vent often means access at a steep roof peak, it’s advisable to call a professional if you have any doubts about safety or roofing skills. When you contact a roofer, ask whether they use flexible roofing sealants compatible with steel panels and if they will inspect the entire vent system to identify underlying damage. Also, check if their work comes with a warranty covering leaks after repairs, as this is important for peace of mind. Quality contractors will also recommend preventive maintenance to keep the vents and seals in good shape and help extend the life of both your roof and ventilation system.
