Remove Maple Tree Sap From Asphalt Shingles On Your Garage’s Rooftop

Buildup on roofing materials can cause damage and permanent staining if left untreated. If large maple trees surround your garage and tree sap has fallen onto some of the asphalt shingles on the roof, remove it with the following steps. After you have finished, maintain the roof by inspecting and cleaning it throughout the year.


  • ladder
  • safety harness
  • broom
  • garden sprayer
  • detergent
  • water hose
  • work gloves
  • scrub brush
  • putty knife

Remove Debris From The Shingles And Apply A Cleaning Solution

Set up a ladder next to the garage. Put on a safety harness to help keep you protected from injuries while on the ladder. If you do not own a harness, ask a friend or family member to spot you while you are removing the sap from the shingles. Climb the ladder and use a broom to remove loose debris, such as tree limbs or leaves.

Mix equal amounts of water and industrial strength detergent and add the cleaning solution to a garden sprayer's tank. Spray the shingle's that have sap on them with a generous amount of the cleaning solution. Leave the solution on the shingles for several minutes to help soften the sap.

Scrub The Sap-Covered Shingles And Use A Putty Knife To Assist

Put on a pair of work gloves so that your hands do not come into contact with any sap, which could be difficult to remove from your skin. Move a scrub brush that has natural bristles, back and forth over the sap. Hold the brush firmly, so that you have plenty of control of the tool as it is moving over the roofing materials. If any of the sap spots are thick, insert the tip of a putty knife under the edge of them to help loosen them from the shingles. Apply more of the cleaning solution if any of the shingles begin drying before you are able to eliminate all of the sap. 

Rinse The Roof Off And Maintain The Shingles

Rinse the cleaning solution from the rooftop with a strong stream of water. The rooftop will have an improved appearance and the roofing materials will continue to protect your garage's interior. To maintain the shingles, inspect the rooftop regularly and remove debris, especially after severe storms that may have knocked down some tree limbs. Clean the roof periodically by spraying it off with a water hose and spot treating stains with soapy water and a scrub brush. These basic steps will help preserve the shingles so that they remain damage-free.
