This picture was taken at a Rosedale home inspection in Queens, and shows the first row of shingles are cupped because the gutter screens have lifted these shingles and water may not drain off the roof.  This is a common mistake by gutter contractors and homeowners alike, and is why you should have them professionally installed. And no matter what the commercials on TV tell you, gutters and screens still need to be cleaned. The fine mesh screens keeps out debris better than the ones pictured, but the screens get clogged also, and can prevent their proper operation.

So don't be ridiculous, call Meticulous Home Inspection at 631 902 6761. Available 7 days a week, and in business since 2005.
