If you’re worried that your roof is unsafe, there are a few symptoms that can help you figure out what’s wrong. First, get a roof inspection, both inside and out, to look for broken shingles, dark stains, sagging, rotting/mold, or leaks/water damage. Even if you can’t see any corrosion or loss, determining the age of your roof is beneficial. Most of the time, you’ll need to call a local roofing company like Delta Roofing to visit and assess the condition of your roof. Annual roof inspections are provided by local roofing companies, during which roofing experts evaluate your roof.
