How to Remove Moss from Your Roof – Step by Step Guide

A mossy roof is more than an eyesore, its a threat to the structure of your roof and your house. Killing moss with vinegar is one strategy for removing it from your roof, but there are others. You should proceed with caution with any such repair due to the slippery nature of moss and the inherent danger of working on a roof.

First Off What Is Moss

Mosses are a collection of tiny non-vascular flowerless plants that thrive in damp or shady conditions. Unbeknownst to many, there are seven classes and 12,000 known varieties of moss worldwide. It’s non-vascular, which means that moss doesn’t have roots like other plants do, and instead absorbs water from its appendages or spores. Because it doesn’t have the root structure to grow upward, it’s a plant that grows low and spreads wide on flat surfaces.

When moss spreads, it can envelop the surface and create a somewhat rustic look for cottages or cabins, which is why some people choose to let moss grow on their roofs. However, the consequences of allowing moss to grow wild are often not worth it.

Tips For Installing Zinc Or Copper Strips

When installing the metal strip its crucial that you do not use nails to hold it in place this will cause leakage when rain drips down along the nail and through the roof structure. Its also essential to ensure the zinc or copper strips are lying thin and as close to the roof as possible, to prevent warping. When warping occurs, the area of the roof beneath it does not get treated by the strips because instead of running directly down the roof, it runs along the strip to a less warped area.

Whichever method you choose, its important to look at other factors that cause moss growth and try to remove these. For example, trimming overhanging trees and bushes will remove shade which moss needs to grow, and moving any satellite dishes to areas that wont create shade. The more sunlight your roof is exposed to, the less shade and moisture will be present, so the less likely moss is going to grow.

Why Shouldnt I Add A New Roof Over Moss

When you need a new roof, it may be tempting to add a second layer of shingles over your existing shingles. Doubling up your shingles can save time and expense on your roof replacement as your roofer doesnt need to remove and dispose of the old shingles. This strategy is convenient for homeowners because the replacement wont take as long or make as much of a mess. However, there are some circumstances where merely adding a new layer of shingles isnt a good idea.

For example, when you have significant moss growth on your roof, simply covering it up with new shingles isnt wise. Several potential problems may occur if your roofer simply adds a new roof over your existing, moss-covered roof. These potential problems include:

Roof Moss Removal: Methods And Prices

Removing moss from the roof is absolutely necessary to guarantee the proper functioning of the water drainage and to prevent the roofing from freezing to pieces. There are several methods to remove moss and dirt from the roof. You can discover these methods here, as well as the price for roof moss removal.

How Moss Ruins A Roof

In general, it is north-facing roof areas that receive little sunlight that are prone to mossespecially when the overall climate is cool and damp. But even in damp climates, roof areas that receive even a little strong sunlight each day may not develop moss. You are most likely to find it on areas of the roof that are shady nearly all the time, such as roof areas beneath heavy tree canopies

Roof moss begins with a thin dusting of green that you may notice only from low angles. This thin layer on the top of the shingles gradually expands and becomes wide, thick, and mat-like. The seams between the shingles and the shingles’ edges also develop moss because they tend to be especially shaded.

As moss thickens, it works its way under the shingles and raises them up. If the shingles are wood, this process can happen at an alarming ratewood’s porous surface is prime real estate for moss growth. Once moss has adhered to wood shingles, it is much harder to remove than from the relatively smoother planes of composite or asphalt shingles.

Once the moss is a thick mat, it becomes a sponge that soaks up and retains all moisture. This stored water quickly works its way under and between shingles and then onto the lower levels of roofing felt and the structural elements of the roof. This eventually leads to rot, and rot leads to further decay of roofing materials. The accelerating cycle can even destroy a roof in a matter of a few months.

How To Prevent Moss On Roof

Happily, there are preventive measures you can use to keep your roof moss-free. First, let the sunshine in! Trim branches overhanging your roof, keep gutters free of debris, and regularly remove moisture collectors, such as leaves, branches, and seedpods, that pile up on the roof and encourage moss to grow. The best long-term solution? Attach strips of zinc or zinc-coated metal flashing strips just below a roof’s peak or ridge caps. When it rains, water flows over the metal strips leaching out moss-retardant zinc particles, which attach to roof shingles and/or tiles to stop new moss from forming.

Working safe, smart, and strategically guarantees your moss-removal operations will run smoothly. These prevention measures mean you’ll be able to stay off the ladder and roof for seasons, if not years, to come.

Maintenance Solutions

To understand how to deal with the recurring problem of algae and moss growth on rooftops, it is important to learn what they are and how they grow and spread. Although some similarities exist, algae and moss are very different and require slightly different procedures to prevent or to remove.

Often mistaken as mold or mildew, the black discoloration and streaks visible on many roofs across the United States and Canada are actually algae. The algae can form w here moisture tends to dwell on roof surfaces. Coastal or humid climates create the most conducive conditions for algae growth. The most common type, gloeocapsa magma or blue green algae, protects itself from damaging ultraviolet rays by producing a dark pigmented sheath. The algae discoloration typically begins as small spots then quickly transforms into streaks on the roof plane. By the time the algae is visible, it likely has been present for several months or longer.

Moss is a non-vascular plant that obtains water through its leaves, unlike most plants that gather water through its root system. Moss must therefore have a moist environment to survive. In North America, moss tends to grow on north facing roof planes that receive less direct sunlight and stay damp longer than south facing planes. Overhanging tree branches provide additional shade and drop debris on the roof that further holds in moisture and acts as a food source for moss.

What Are The Dark Streaks On My Roof

Remove Moss From Roof | DIY | 2 Methods

You may have noticed dark streaks across your roof. Given that moss grows upright on surfaces, and algae stays low and flush to the surfaces it grows on, its likely any dark streaks you see are algae.

Algae staining on roofs all start out being spread by wind, birds, and varmints, affecting homes across much of the United States.

This algae normally begins its lifecycle as airborne spores that will settle on your roof, especially those roofs that have asphalt shingles. The northern exposure of roofs has the most chance for algae to survive/thrive because that part of the roof is exposed to the least UV and dries last after morning dew and rain.

As the algae grows and spreads, it begins to look like large black streaks on your shingles.

Its All About The Tiles

Whilst a mossy roof might not be aesthetically pleasing, you could end up in a lot more trouble should you decide to remove the spongy green invader from your roof tiles. When moss grows in, under and around your roof tiles, it actually acts as a filler packing out any gaps and plugging the spaces. Destroy the moss and those tiles that were previously held up by it are likely to settle back down in an awkward way. This could result in a roof that isnt water tight, leading to bigger problems down the road.

How Does Moss Get On Your Roof

Moss likes cool, damp places that lack in the sunshine. If your roof is not fully exposed to the sun, then it stands a good chance of developing a moss problem. It does not matter the type of shingles you have on your roof, wood, asphalt, etc., If the roof is cool, damp and dark, then moss will take advantage of the situation.

At first, the moss may not seem like a problem. But as it grows, it becomes a natural jack and lifts up your shingles. This action can help water to get under the shingles and cause leaks. These leaks will lead to further damage to your home other than the roof.

The worst type of roof to have is the wood shingle style. Since the wood is porous moss can get a good hold on the shingle and not let go.

Difference Between Moss And Algae

Though they might be grouped as the same thing because they grow in the same area of your home, moss and algae are actually quite different and distinct.

Moss always appears more green and fluffy-looking than algae, though it might appear browner during dryer seasons. Moss will also grow up off the roof, while algae will grow flush to the shingles and fixtures, staying flat and unobtrusive. Algae will appear in many different colors such as gray, blue, green, or brown.

A small amount of moss is relatively harmless, but left unattended, it can grow and eventually damage your asphalt shingles. Moss should be removed. Algae actually fosters the growth of mold, which can lead to very serious issues. Algae, too, should be removed quickly and efficiently.
