If your home's asphalt-shingled roof has been subjected to inclement weather conditions, you may notice that portions of the roofing materials are loose or covered with debris and surface stains. Loose shingles can cause the rooftop to leak and moisture that remains on shingles can cause mildew streaks to form. Learn how to repair and clean the rooftop by completing the steps below. Once the roof problems have been addressed, maintain the rooftop to assist with keeping it in excellent shape.

Materials Needed

  • extension ladder
  • safety goggles and harness
  • rake
  • roofing nails
  • nail gun
  • hammer
  • pry bar
  • replacement shingles
  • water hose
  • industrial detergent (designed to be used on shingles)
  • garden and lawn sprayer
  • oxygenated bleach
  • long-handled scrub brush with stiff bristles

​Remove Debris And Secure Or Replace Loose Shingles

Set up an extension ladder next to one side of your home. Put on a pair of safety goggles and secure a safety harness to a sturdy object. Remove tree branches, leaves, and any other debris that is on the rooftop with a rake. Inspect each of the shingles. Use a nail gun to install roofing nails in the corners of any of them that are loose.

If any shingles are badly damaged and can not be reattached to the roof, remove them by using the back of a hammer or the edge of a pry bar to pull out the roofing nails that are attached to them. Line up new shingles, like those from American Building & Roofing Inc, where needed and secure roofing nails through each one's corners.

Use A Cleaning Solution And Scrub Brush To Eliminate Stains

Remove a garden and lawn sprayer's holding tank and fill it almost to the top with water. Add a small amount of detergent that is designed to be used on shingles to the water. Mix the components that were added to the holding tank until you see visible suds. Apply a generous amount of the cleaning solution to stains on each asphalt shingle. Loosen and eliminate the stains by briskly moving a scrub brush with stiff bristles back and forth over each dirty surface.

For severe stains, add a small amount of oxygenated bleach to the garden sprayer's tank before treating each spot on the roof. Once the rooftop is stain-free, rinse the asphalt shingles with a water hose that is adjusted to a setting that provides strong water pressure.

Protect the asphalt shingles from extensive damage and staining in the future by inspecting the rooftop regularly and removing loose debris and dirt at random times throughout the year.
