Most of the time, you’ll notice a leak or leaks occurring after a heavy rain. In this case, you may be dealing with an emergency repair. Sometimes, you may not physically see a leak, but you may notice damage or a moldy odor on wood in your house.
Even roofs that are relatively flat have some sort of slope to them, so the location of the leak in your house may not be the exact location externally. In addition, sometimes it isn’t the roof at all, but a piece of flashing around the chimney, the vent pipes, or even the gutters. A roof inspection is the best way to find out exactly what needs to be repaired.
