Yes. Wind-driven rain can enter a ridge vent in Minnesota when strong lateral wind, poor vent design, damage, or bad installation line up. Still, ridge vents get blamed for many leaks they did not cause. Water near the peak often starts at ridge caps, exposed fasteners, upper flashing, or nearby roof seams. For commercial owners,…
Yes, roof nails backing out is a common issue after repeated freeze-thaw cycles in Minnesota. This phenomenon, often referred to as nail pops, occurs when moisture enters small gaps and freezes. The subsequent expansion and contraction of materials as temperatures fluctuate puts significant stress on the entire roofing assembly. This movement can lift asphalt shingles,…
Yes. Wind can damage ridge vents even when shingles still look fine. The ridge sits at the highest, most exposed part of the roof, so uplift often hits the vent first. On commercial buildings with steep-slope roof sections, that can mean a loose or broken vent, minor leaks, and hidden moisture, even without obvious shingle…
Yes. Hail can dent, crack, or loosen roof vents even when shingles look untouched. Vents sit above the roof plane, and many use thinner metal, plastic, or rubber parts than the surrounding roof. On a commercial building, that means a storm can damage a vent cap, boot, or flashing first, then let water in later….
Bathroom fan roof vent leaks usually show up as ceiling stains, drips at the fan grille, wet insulation, or rust around the roof cap. In Minnesota, snow, ice, and freeze-thaw cycles often crack flashing or sealant around the vent, so a small drip can point to a bigger roof issue fast. When This Applies This…
Start by inspecting the rubber pipe boots where they hug the pipe, then the base flashing where it meets the roof. Look for radial cracks, splits at the top edge, loose sealant, and lifting edges from freeze-thaw. On Minnesota commercial roofs, check after big temperature swings and after snow events, then document damage and schedule…
You can spot hail damage roof vents from the ground after storm damage by looking for fresh dents in metal vent hoods, cracked or chipped vent caps, bent flashing lines, and vents that look tilted or “squashed.” Use binoculars, check multiple angles, and compare vents to each other. If you see dents plus interior moisture,…
Most homes follow International Residential Code R806 style rules for attic ventilation to the outdoors, size vents using the 1/150 rule (or 1/300 when conditions allow), keep intake and exhaust balanced, and protect openings with screens and weather protection. I work on Minnesota roofs, and our cold winters make moisture control and ice dam prevention…
Pixabay Let’s face it, men aren’t as handy as they used to be. In years past if you asked the average man, how many air vents you’d need for your roof, he’d have an answer for you and probably a story or two to go along with it. Today, most guys would have to look…
