Your roof has a major impact on the value of your home, and that is one of the reasons why you need to makes sure that it remains undamaged and well-maintained at all times. For those looking to sell or refinance their home, the roof is a major part of what home inspectors consider when deciding the market value. If you’re not sure whether or not your roof is reflecting the best of your home, here are for major factors affecting your roof’s quality. Improper Ventilation or Insulation Many homeowners don’t realize that roofs and attics require proper ventilation. All of the moist air throughout your home is going to collect near the roof, and that will create the perfecting breeding ground for black mold if the air can’t escape. Once or twice a year, you should inspect all of the vents throughout your attic to make sure that they aren’t covered or clogged. Every roof is different in their ventilation needs, and having too much ventilation can be as bad as not enough. Too much will compromise your home’s energy efficiency by releasing all of your home’s heat. It’s important, then, to have a roofing professional inspect your ventilation and discuss your home’s needs based on use, home size, and roofing material.
