Chimney Sweep questions, answered by experts

Just about anything that can damage your roof can damage a solar panel. It’s common for panels to sustain damage from hail or falling branches. Critters can chew through the wires. Snow and heavy rainfall can cause additional wear, along with extreme temperatures, which can degrade or stress the individual components. Even the UV rays that create electricity slowly damage your panel over time.

It is generally not safe to live in a house with smoke damage, as even minor damage can pose long-term health hazards and structural risks. While it might seem safe temporarily depending on the severity, you should relocate if there is major damage or visible soot. Smoke smells and residue contain dangerous particulates and chemical compounds, including carcinogens, that are hazardous to breathe and can cause respiratory issues. These signs of damage are not always visible but can have dangerous short-term and long-term effects on your health, belongings, and your home's structural materials. You should not stay in the house until a trained professional from a smoke remediation or restoration company has assessed the damage and determined it is safe to return. Your insurance company may cover the cost of alternative housing while the professional work is completed.

Professionals remove soot, restore structural integrity, and eliminate smoke odors safely.

Ozone smoke removal uses an ozone generator to eliminate stubborn odors from sources like house fires, wildfires, or cigarette smoke. Ozone (O3) is a highly reactive, unstable gas that neutralizes odors by oxidizing the organic compounds it comes into contact with. During this oxidation process, ozone "donates" its extra oxygen molecule to the smoke particles, effectively eliminating their smell, with oxygen being the primary byproduct. While ozone can be effective for removing smoke smells from building materials and belongings like wood furniture, this treatment is best left to a professional, as improper use of an ozone generator can be dangerous to your health.

Yes, most insurance plans cover acts of nature. In policy documents, this also may be called “Acts of God” or “natural disasters.” However, not all acts of nature are covered by your policy, and the extent to which they’re covered depends on your specific contract. Check your policy documents to understand your coverage limits and exclusions.
