What benefit is there in spending money every year to maintain the roof? Studies have shown that a roofs not regularly maintained will only last about half of their expected service life. You might say "That's why I have a warranty.", but don't assume that a warranty will help. Almost all manufacturers of roofing materials state specifically in their warranty that your warranty is void if the roof is not maintained. If you can not show that the roof has been properly and andequately maintained, you will not have a case when you try to make a claim on a warranty issue.
Your roof should be inspected at least twice a year to keep the roof alive as long as possible and to maintain your warranty. Depending on the depth and complexity of the inspection, the inspector can be the building staff, an architect or engineer who specializes in roof consulting, or a competent roofing contractor. The inspection can entail anything from looking at the roof while walking to repair an A/C unit, all the way to a formal inspection with a moisture survey.
