How To Check Roof Vent Pipe Boots For Cracks In Minnesota
ByTed Sellers March 16, 2026May 26, 2026

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…

How Do You Find A Shingle Roof Leak Around Dormers
ByTed Sellers March 16, 2026May 26, 2026

A dormer roof leak is usually found by tracing water backward from the first interior stain to the highest wet point, then checking the dormer’s flashing, valleys, and shingle courses above that spot. Start inside (attic or ceiling), mark the drip line, then inspect uphill around step flashing and the dormer cheeks. If needed, run…

ByTed Sellers March 15, 2026May 26, 2026

Short Answer: To find a commercial flat roof leak at an expansion joint, start by mapping where water shows up inside and when it happens.

What Is Kickout Flashing On Minnesota Homes And Why It Matters?
ByTed Sellers March 13, 2026May 26, 2026

Kickout flashing is a small, shaped piece of metal installed where a sloped roof ends against a wall, right above the gutter. Its job is simple: push roof runoff into the gutter instead of letting water slide behind siding. In Minnesota’s snow, ice, and wind-driven rain, its absence can lead to water damage and moisture…

How Do You Find a Roof Leak at TPO Wall Flashing?
ByTed Sellers March 13, 2026May 26, 2026

A TPO wall flashing leak, a common roof leak on a flat roof, is usually found by tracing water from the interior stain back to the nearest wall, then inspecting the roof to wall flashing where the TPO membrane turns up the wall. Focus on terminations (termination bars, counterflashing, reglets), corner patches, fasteners, and sealant…

How Do You Detect an HVAC Roof Leak at Curb Flashing?
ByTed Sellers March 13, 2026May 26, 2026

Short answer: Detect an HVAC curb flashing leak by inspecting the curb’s corners, seams, and termination points, then confirming moisture paths with interior checks. Look for cracked roofing sealant, open welds, lifted membrane, rusted fasteners, and ponding that pushes water against the curb. If signs are mixed, use targeted moisture mapping or a controlled water…

How Do You Find A TPO Roof Leak At HVAC Curb Corners?
ByTed Sellers March 12, 2026May 26, 2026

A TPO roof leak at HVAC curb corners is found by narrowing the leak path from the interior, then inspecting every curb corner detail on the TPO membrane: welds, flashing, termination, fasteners, and sealant transitions. Finally, confirm the exact breach with controlled water testing or professional methods like infrared or electronic leak detection, because water…

How Do You Find a Roof Leak From a Ceiling Stain?
ByTed Sellers March 12, 2026May 26, 2026

Water stains on ceilings help you narrow the search, but they rarely mark the exact roof leak. Start by confirming the stain is active, then check what sits directly above it (roof deck, drains, HVAC curbs, or plumbing). Next, trace the most likely uphill water path on the roof to find the leaky roof, focusing…

How does roof leak detection work on PVC flat roofs?
ByTed Sellers March 11, 2026May 26, 2026

PVC roof leak detection works by narrowing the problem from “moisture intrusion inside” to the exact point where the PVC waterproofing membrane or flashing lets water in. Pros use Electronic Leak Detection, combining surface inspection, seam and flashing checks, moisture scanning (often infrared), and electronic membrane testing to trace the leak’s path, pinpoint membrane breaches,…

How can I tell if my roof is leaking from a leaking skylight or the flashing (Saint Paul photo checklist)?
ByTed Sellers March 9, 2026May 26, 2026

A skylight flashing leak usually shows up as a roof leak in the form of staining that starts at the skylight’s edges (often the uphill side) and worsens during wind-driven rain or thaw cycles. A skylight unit leak or condensation issue tends to leave moisture on the glass, frame, or inside corners first. The fastest…

How Do You Find a Leak at Flat Roof Parapet Walls?
ByTed Sellers March 7, 2026May 26, 2026

A flat roof parapet leak usually comes from one of three places: the roof membrane’s transition to the parapet wall, the metal coping on top, or a drainage opening that cuts through the parapet (like a scupper). To find it, start by tracing interior staining to the closest wall line, then inspect parapet flashings, terminations,…
