Without adequate roofing ventilation, a handful of issues can arise, affecting not just the roof structure itself but also the rest of your home. It can also hurt your wallet in the form of frequent but expensive repairs. Fields Roof Services, Inc. takes a look at some of the problems caused by poor roofing ventilation.
Mold and Mildew Growth
Any lack of ventilation can create a persistently damp environment, which is ideal for mold and mildew to proliferate. This not only poses health risks but can also damage stored belongings and weaken structural materials. It’s absolutely crucial for a roofer to ensure that ventilation systems in your roof are functioning appropriately to prevent these dangerous infestations.
Rust and Corrosion of Metal Components
An often-overlooked consequence of poor roof ventilation is the rusting of metal components such as nails, fasteners and venting straps. An environment with trapped moisture significantly accelerates the oxidation process. Regular roof inspections can help identify early signs of rust and address them before major roof leaks or structural issues occur.
Damage to Roof Decking and Shingles
Washington’s temperature ranges contribute to significant expansion and contraction in roofing materials. Excessive heat and trapped moisture can cause roof decking to warp and shingles to crack or lose granules prematurely. Both roof contractors and homeowners should be vigilant about signs of distress in their roofing materials, which may indicate poor ventilation.
Increased Energy Bills and HVAC Strain
Another hidden cost of inadequate ventilation manifests in higher energy bills. Excess heat in attic spaces forces air conditioners to work harder, raising energy consumption and putting undue stress on the HVAC system. As Field Roof Service will attest, proper attic insulation combined with effective ventilation can make a notable difference in maintaining a cool and cost-efficient home during warmer months.
Ice Dam Formation and Roof Leaks
Winters can bring snow and with it, the risk of ice dams. These form when heat escapes through a poorly ventilated roof, melting snow which then refreezes at the roof’s edge. Over time, this can result in damaging leaks and require urgent attention from a reputable roofer equipped to deal with emergency roof repair, like those at Fields Roof Service.
Condensation, Paint Damage and Interior Decay
Lastly, excess moisture from poor roof ventilation doesn’t just stay in the attic; it can seep into living spaces, causing paint to peel, wooden structures to decay and even ceiling stains. Ensuring that roofing systems have the correct balance of intake and exhaust ventilation can shield interiors from these types of damage.
