Cleaning the roof is important.You may notice that your roof is turning black one day.Some of the growth, such as moss, can cause costly damage to your roof.Pick a cool, overcast day and mix a cleaning solution, spray it onto your roof and rinse after 20 minutes.
Step 1: Choose a cloudy day.
The day you deep clean the shingles should be cool and cloudy.The warm weather will make the cleaning solution dry too fast.If you choose a day with little wind, the solution will stay on the roof.
Step 2: It's a good idea to perform maintenance on your roof.
It is important to repair loose shingles and flashings before you start.You should clean out your gutter and downspouts after that.You need a cleaning solution to drain off the roof.
Step 3: You should protect your yard.
Furniture should be moved away from the work area.You should also cover your yard if you are using a bleach solution.Before you begin deep cleaning, you should rinse your lawn and plants and cover them with plastic to catch any spray.
Step 4: The debris needs to be removed from the roof.
twigs, leaves, and anything else that could get in the way will have to be taken off before you can clean the stains.Pick them up, use a leaf blower, or sweep them off with a broom.
Step 5: You can mix your cleaning solution.
A quart of laundry bleach and a gallon of water can be used to make a home cleaner.Add 14 cup (177.5 mL) of a non-ammonia heavy cleaner for extra cleaning power.It is caustic to the plants.50% of the solution should be bleach.lye products are caustic to the skin and should only be handled while wearing protective gear.Look for a detergent specifically made for shingled roofs if you want a cleaner from the store.
Step 6: The shingles need to be soaked with water.
There is a garden hose on the roof.Start from the bottom.The solution won't dry out immediately after application.Stop when you see the water.
Step 7: You can spray your cleaning solution.
Put the solution into a sprayer.Use slow strokes to coat the shingles.If you miss any spots, your roof will come out spotted.Take the solution for 15-20 minutes.
Step 8: Get rid of the solution.
If you want to remove moss and algae from the shingles, use a water sprayer.A garden hose may be enough in a lightly-stained roof.Again, slow down.Make sure you reach all of the cleaner by moving back and forth in strokes.Power washers shouldn't be used.They will destroy your shingles.
Step 9: Re apply the solution.
You have to put on more solution for deep stains.When the roof is dry, wet it and spray it the same way you did before.Wait 30 minutes and rinse it off.Light stains may wash off over time if rain and sunlight can reach the area.A broom can be used to clean.You don't want to damage the integrity of the shingles by using a broom.
Step 10: You should clean your roof every now and then.
The debris has a moist environment for moss and algae.It needs to be picked up, swept off, or blown off.Water can't drain freely if the gutter is MzEd.It's much easier to clean stains later on.
Step 11: Take care of nearby branches.
The shady environment that moss and algae need to bloom is created by hanging plant life.Move tree branches or plants that shade your roof.Exposure to the sun will keep moss and algae from growing.
Step 12: A stain blocker can be applied.
Resistance can be up to three years.At a home improvement store, you can find roofing and moss blockers.According to the directions on the label, spread the stain blocker after you clean your roof.
Step 13: There are metal strips under the shingles.
There are copper and zinc strips in home improvement stores.Some of the metal is washed away by the water when it rains.When placing a new roof, it is best to install these strips because they can puncture the sealant on the shingles.It may be possible to string copper wire.
