We know that generally by year 10 after installation, your pipe boots start to crack, your nail beds need to be recapped and some of your accessories are no longer covered. Because roof warranties drop by about 30% every 10 years, we always recommend homeowners to get preventative maintenance service.
Homeowner Tip: Crawl into your attic and verify ventilation.
Because of the nature of roofs, there isn't a whole lot homeowners can do in terms of daily maintenance. One of the things that you can do however is to take a peek into your attic. Because some inspectors don't crawl through the attic in a preventative maintenance inspection, taking a few minutes to verify ventilation could save you thousands of dollars.
With the lights on, check for discolored or moldy sheathing. Mold and discoloration will lead to 20% decrease of life in your shingles and serious health concerns for your family. If you notice mold, get people out of the home and call a professional to come take care of it.
To check on your roofs ventilation, turn out the lights and check for any light coming through the eves. Light equals air and air equals ventilation. Sheathing should stay around 120 degrees. With poor ventilation temperatures can rise to 190 degrees leading them to burn up and break down.
