2. Musty Odors

Other Ways to Protect Your Malvern Home from Mold
Roofing is only part of the equation. Other areas of your exterior can also contribute to moisture problems if not properly maintained.
Keep Gutters Clear
Clogged gutters prevent water from draining properly, causing it to back up under shingles or overflow near the foundation. This not only damages your roof but also creates damp conditions that mold loves. Installing seamless gutters or gutter guards can make a big difference in preventing water damage.
Check Your Siding
Damaged siding can let water seep behind walls, where it contributes to mold growth. Cracks, warping, or loose panels should be addressed quickly. Regular siding inspections, especially after storms, help you catch issues early.
Ventilate Your Attic
Poor attic ventilation traps humid air inside your home, increasing the risk of condensation and mold. A properly ventilated attic lets moisture escape instead of collecting on rafters and insulation.
