You might have the impression that little moss on the roof might not be harmful as it gives character to the roof, but this isn’t the case. According to slate roofing contractors, any amount of moss on your roof is detrimental as it comes with plenty of negatives.
Dangers of moss on the roof
Unlike soil, shingles are dry and nutrient-free and as a result, moss grows its roots directly into the shingles which can destroy the shingles and create opportunities for leaks.
When it rains, moss soaks up water and retains it which keeps your roof wet most of the times which isn’t healthy. The extra weight of the water also puts the roof at the risk of coming down.
When you don’t remove the moss early enough, it might begin interfering with the proper water drainage as water has to trickle through or around the moss instead of running straight to the gutters.
Overtime, the moss can work its way under the shingles and lift them up. This uplift creates opportunities for water to penetrate the lower layers of the roof and damage them.
How to remove moss from roof naturally
There are plenty of ways you can remove moss from your roof, but not all are natural and healthy for your roof. To get rid of moss naturally and safely, you need to follow the right procedures.
Begin with finding the materials you need for the work. These include: garden hose, garbage bag, ladder, moss cleaner or your own custom cleaner mix.
Once you have the necessary materials, now begin the cleaning.
Set the ladder near the moss, then spray with your cleaner. Carefully follow the instructions given on the label on how to spray the cleaner and how long you should leave it on the moss. If using a homemade spray, leave it on the moss for 15-20 minutes.
With the garden hose set on low pressure, rinse the moss thoroughly. As you are rinsing, you will find that most of the moss will come off from the water spray, so don’t direct a pressurized spray beneath the shingles or directly against the shingles as they might lift, creating a leak.
Even if some moss is coming off, continue hosing and remove all the cleaner that you had sprayed on.
For the remaining moss, loosen it enough that you can manually remove it from the shingles. You should then stand on a ladder and gently lift the moss from the shingles and place it in the garbage bag for disposal. To always have one hand on the ladder for security reasons, secure the garbage bag to the ladder.
It’s common to find some moss too ingrained on the roof that you can’t remove it by hand. In such a case, don’t try to brush or pressure wash the moss as this will damage your roof. Instead, get in touch with a professional roofer to advice you on the next steps to take.
How not to remove moss from your slate roof
While some methods are effective at removing moss, it doesn’t mean they are good to follow as they can damage your shingles.
Although, some of these methods are recommended by some websites, be wary of them as they can lead to serious damage to your roof. Some of the things you shouldn’t do to your roof include:
Scrubbing: You might be tempted to scrub the moss off the shingles when moss grips the shingles too strongly, but don’t do it as it will damage the shingles and remove their granules.
Pressure washing: You also shouldn’t pressure wash your roof as the pressure might be too strong and break the shingle’s adhesive and lift it up. The pressure might also strip the shingles of their granule surface, which can ruin their performance and destroy their color.
Harsh chemicals: When moss isn’t coming out, you might be tempted to kill it using chemicals but don’t go this route as you can cause serious damage to your roof, increasing your risk for leaks.
If having an issue removing the moss, don’t use chemicals or any other damaging method. Instead, get in touch with roof repair services Old Greenwich CT and consult them on the best way to remove the moss.
