This inspection covers various systems and components, including the roof, attic, heating and cooling systems, plumbing, electrical, interiors, doors and windows, fixed appliances, external conditions, and more. Even if you had a thorough first inspection, there’s always a chance that some defects may not become apparent until the 11th month, which makes this type of inspection essential for homeowners. Some common issues during an 11-month inspection include appliance or cabinet damage, cracked or damaged shingles, improper roof vent installation, leaking plumbing, loose toilets, cracks in stucco, and missing grout.
