As a landlord, you must keep your property in good condition. This includes carrying the roof, which is one of the most important pieces of your property. If it starts to leak or otherwise fails to function properly, then it can lead to problems with mold growth or water damage inside your building.
The best way to prevent this is by regularly maintaining your property's roofing system. This means checking for signs of wear and tear or damage to parts like shingles or flashing every year. If you see any issues, make sure you fix them immediately before they become serious problems that could cause leaks or other issues with water damage inside your building!
