Cleveland's proximity to Lake Erie creates high relative humidity throughout the summer, often reaching 70 to 80 percent by mid-morning. When this moisture-laden air enters an attic through unsealed penetrations or inadequate ventilation, it condenses on the underside of the roof deck. The moisture migrates into the shingle layers, creating the perfect conditions for blister formation. In winter, the same attic can drop to subzero temperatures, freezing any trapped moisture and causing it to expand. This freeze-thaw cycle happens dozens of times each season in Cleveland, and it destroys shingles faster than in drier climates. If your roof was installed without proper ventilation, blistering is not a question of if, but when.
We have worked with Cleveland homeowners since 1998, and we understand the specific ventilation challenges in older neighborhoods like Detroit-Shoreway, Edgewater, and Kamm's Corners. Many of these homes were built with minimal or no soffit vents, relying instead on gable vents that create uneven airflow. We have also worked with the Cleveland Building Department on dozens of permit applications for roof repairs and ventilation upgrades. We know the local inspectors, we know what they look for, and we know how to get your project approved without delays. When you hire us, you are hiring a team that has solved Cleveland's roofing problems hundreds of times.
