After a weekend storm, a homeowner in Ashville, OH reported active water leaks inside their six-year-old home. Although the roof featured asphalt shingles in good overall condition, the area around the chimney was showing signs of water intrusion. The homeowner had already reached out once for an estimate but called again after the situation worsened, especially with water visibly entering the home during heavy rainfall. The existing flashing system around the chimney chase appeared to be failing, and a proper cricket (a small roof ridge to divert water) had not been installed behind the chimney—allowing water to pool and penetrate critical seams.
Solution
Klaus Larsen Roofing responded promptly to reassess the issue and develop a long-term solution. The team confirmed that the leak was isolated to the chimney chase and required precise repair work including better water diversion and flashing integrity. The plan involved building a proper cricket behind the chimney to redirect water, lifting the siding on the chimney chase to install Sealoron XT ice and water barrier for superior moisture protection, and replacing the flashing with new, properly sealed aluminum. To finish, a new Perma-Boot was installed over the vent pipe to prevent any further leakage in that area.
After a powerful weekend storm, the homeowner noticed water coming into the home around the chimney area. Although the asphalt shingles were only six years old, signs of water intrusion pointed to an issue deeper than surface wear. A prior inspection had flagged the need for attention, but the storm accelerated the problem-making a solution urgent. Water was pooling behind the chimney where there was no cricket in place to guide it away, and the existing flashing appeared to be failing. The vent pipe also showed signs of deterioration, raising concerns about long-term sealing.
Once back on site, our team performed a full re-evaluation, confirming the water was collecting behind the chimney and sneaking in through weak flashing. We got to work by framing and installing a new cricket to redirect water flow left and right from the base of the chimney. To create a watertight seal, we gently lifted the siding around the chimney chase and installed Sealoron XT underlayment-extending it up the framing for added protection. Then, we replaced the old flashing with a properly fitted new system that layered beneath the siding and over the underlayment. A new 3" Perma-Boot was also installed over the vent pipe, giving the home a reliable, long-term seal with no messy caulking required. Every detail was handled with care to ensure a clean, leak-proof finish.
With the cricket built, flashing replaced, and underlayment securely in place, the vulnerable chimney area was fully reinforced. Final shingle work was completed using Owens Corning Estate Gray, perfectly matching the rest of the roof for a seamless appearance. Not only is the leak resolved, but the home is now better protected from future weather events. The homeowner can feel confident knowing their roof is secure, and the repairs look as good as new. This job reflects our commitment to smart, lasting solutions and doing things the Klaus Larsen Roofing way.
