Attic fan guards are something the whole family can enjoy. They are made to withstand weather and keep wildlife and birds from entering the attic through the fan. There are screens inside of these fans but animals have learn to pull them out or bend them over to gain access. The guard is made to go completely over the attic fan and is screwed down to the roof with washers. All screw holes are sealed with roof cement and I never had a problem with one leaking. In do replace attic fans as well, a attic fan will aid in exhausting hot air from your attic when it reaches a certain temperature.
