Porch roof replacement and wall flashing in Whitehall, Ohio

Whitehall, Ohio · April 2025

What we found and what we did

The homeowners called us about a leak at the low rear porch roof on their two-story Whitehall home, where the porch roof runs into the stucco wall of the house. Water had already caused some damage inside, and they wanted it fixed before it did more. The before photos show where the trouble was: along the wall, the old flashing was a thin metal strip held with rusted fasteners, with gaps and old sealant where it met the stucco, and the shingles on the porch roof were worn.

Rather than patch the wall line, the plan was to redo the whole porch roof. In April 2025 our crew removed the old roof down to the decking, and new wood decking panels went down on the porch roof before anything else. Then came ice and water barrier along the eave, synthetic underlayment over the rest of the deck and new 1.5-inch white drip edge at the edges. The new shingles are Owens Corning Duration in Estate Gray, about 2 squares for this porch roof. Along the wall, the crew installed new black apron flashing and counter flashing and sealed it with black polymer sealant, including the corner where the downspout comes down.

Why the wall line leaks on porch roofs

A lower roof that dies into a wall is a common leak spot. Rain running down the wall and across the roof meets right at that joint, so the flashing there has to do two jobs: one piece laps onto the shingles and turns up the wall, and a second piece covers the top edge so water running down the wall cannot get behind it. When that flashing is a single strip with exposed fasteners, or the sealant has dried and pulled away, water gets in at the wall even when the shingles look fine. If the shingles on the porch roof are also worn, redoing the whole small roof with new flashing is often the cleaner fix. See roof repair in Columbus, repair or replace and roofing in Whitehall.
