š šµ Tucson Flat Roofs: Maintenance Matters More Than Ever
Built-up (flat) roofs are the most common roofing system on Tucson homes and can last 20ā30 years when properly maintained. However, Arizona's intense sun, monsoon storms, and standing water can accelerate wear and tear.
Two of the most common issues homeowners face are:
š§ Ponding Water ā Low spots on the roof can allow water to sit for days after a storm. Over time, standing water breaks down the protective roof coating, increasing the risk of leaks and water damage inside the home.
āļø Blistering Roof Coatings ā Roof coatings can develop bubbles or blisters as trapped gases escape from the roofing materials below. While common, excessive blistering can reduce the coating's effectiveness and may shorten the roof's lifespan.
ā ļø Insurance carriers are becoming increasingly conservative when it comes to older flat roofs. Many companies now have eligibility requirements for flat roofs that are 20 years old or older. Some carriers may require proof of recent replacement (not just recoating), maintenance records, roof inspections, or documentation showing the roof has remaining useful life before offering or renewing coverage.
āļø Inspect your roof regularly, especially after monsoon season.
āļø Keep drains and scuppers clear of debris.
āļø Address standing water issues promptly.
āļø Recoat your roof as recommended by a qualified roofing professional.
āļø Keep records of inspections, maintenance, and repairs for insurance purposes.
A well-maintained roof not only helps prevent costly water damageāit can also help you maintain eligibility for homeowners insurance and avoid surprises when it's time to renew your policy.
