Most preventative maintenance inspections can be performed by homeowners without the help of a roofing professional. Safety should be a primary concern when someone is up on a roof or ladder, however. Most preventative maintenance tasks can be done without actually stepping onto the roof. Cleaning gutters can be accomplished with a brush. Inspections for loose shingles can also generally be done from a ladder and will only require climbing on the roof if shingles need to be secured.
