Prevention is protection

Beyond the full maintenance package done every 3 to 5 years, there are other simple ways to maintain a healthy roof.

1. Stay off the roof. Only walk on the roof when necessary, or hire a roofing professional.
2. Keep it clean. Have leaves, needles, etc., removed form the roof's surface. This ensures the roof to dry evenly and takes away the food source for mosses.
3. Clean the gutters. This should be done one to two times a year depending on your location.

These simple steps will drastically slow the deterioration process, and probably make the full maintenance package more affordable.
