[ad_1]

Most homeowners don’t spend much time thinking about the cleanliness of their roof. As long as it’s not leaking the roof is fine isn’t it? Well the truth is actually rather alarming. Leaving the roof uncleaned can lead to a number of issues that if left neglected can cause considerable damage to the pointing and tiles. This neglect will eventually lead to the deterioration of the roof far faster than if it had been cleaned in the first place. This article will discuss some of the signs of trouble, the causes, and some of the cleaning methods used to eliminate potential problems. Preventative measures are always less expensive than repair or replacement costs.

Black Algae also commonly misleadingly referred to as ‘mildew’ or ‘fungus’ is usually found on the slope of the roof which has the least sun exposure. There are shingles made with zinc or copper that are designed to inhibit algal growth. The most common way to help avoid black algae is to stop branches overhanging the roof allowing more sunlight to shine on your roof. Some people pressure wash the algae which is often a good solution however traditional methods such as cleaning with a brush can also be used so as not to damage a delicate roof. There are also chemical solutions to remedy this problem which will prevent algae and fungus from growing. It is best to contact a professional roofing contractor to help make the right choice, both for you and your roof type.

Debris Staining is a common problem on low pitched roofs with surrounding trees with overhanging branches. Staining occurs when debris such as tree leaves collect on the roof. These piles retain moisture and can cause serious damage if left unchecked. Both algae and fungus originate here as well as the growth of plants which eventually can cause large roof leaks. Moss, lichens, and other plant life will thrive on a neglected roof and the best method of fixing this problem is usually roof cleaning. Care should be taken not to damage any shingles or other roofing material.

Black Streaking occurs on your roof in the form of streaks which is usually caused by bleed through of the bituminous material in asphalt shingles which begins to break down and bleed from the shingle. This is usually a sign of faulty materials or that your shingles are in need of replacement.

Why Clean the Roof?

There are a number of roof cleaning issues that if left unchecked, can wreak havoc on your roof. Shingles, shakes and tiles eventually deteriorate due to weathering and the effects of mould and affect the roof structure itself. It is important to be able to notice the signs that your roof needs cleaning and the causes that lead to the deterioration of your roof. Preventative measures such a roof cleaning are much cheaper than repair or replacement costs associated with restoring a neglected roof.
