HOW CAN IT BE CLEANED?

Typical roof cleaning techniques in Florida involve Pressure Cleaning or Chemical Cleaning with either Chlorine Bleach or newer, more environmentally friendly cleaners. Each approach has its advantages and disadvantages.

Chlorine Bleach: A light chlorine bleach and water resolution can be utilized followed by a thorough rinse. Of course, because chlorine bleach can be toxic, correct care ought to be taken to defend the surrounding property from overspray and runoff. The benefits in using chlorine include a quickly cleaning procedure and minimal rinsing as compared to other approaches. This translates into significantly much less wear & tear on the roof – particularly asphalt shingle roofs. The disadvantages incorporate the fact that Chlorine Bleach is incredibly corrosive and will harm the metal fasteners, flashings, and fixtures on the roof as properly as the underlying waterproofing
membrane – specially in the quite high concentrations frequently employed by several businesses here in Florida. This harm can go unnoticed for years just before the dilemma becomes evident. Note: Never Allow High-Strength Chlorine Bleach solutions to be used on any roof.

Enviro-Friendly Cleaners: These cleaners are normally oxygenated-bleach based merchandise or mild detergents that are significantly safer for the roof and landscaping, but they usually call for a lot far more rinsing than the Chlorine Bleach approach so they are a lot more labor-intense and mean much more foot visitors on the roof. A high quality enviro-friendly item can be employed on any roof
and should not require any far more than 100 psi to successfully rinse a shingle roof and even then, some granule loss ought to be expected.

Pressure Cleaning: Pressure cleaning is an choice that should only be used on a concrete, clay, or standing seam metal roofs. Pressure cleaning eliminates most of the landscaping and chemical concerns, but it is very time consuming and it exerts tremendous force on a surface that is not really created to handle it. In addition, repeated pressure cleaning can wear away
the surface of some tiles that are only covered by a thin layer of coloring. When this happens, the grey concrete color begins to show by way of and the roof need to be stained or painted. Note: Never ever Permit High Pressure to be utilised on Asphalt Shingles or Stone Coated Steel Roofs as this can easily cause irreparable damage.

THESE Methods ARE NOT A Lengthy-TERM Resolution

Even though these strategies are comparatively safe and successful when carried out properly, repeated cleaning with these strategies will lead to premature aging of the roof.

The natural erosion that occurs more than time from the fundamental forces of heat, cold, wind, and rain alone are enough to bring most roofs to the point where annual inspections and minor repairs are a necessity to avoid unexpected and significant repair costs. But when the roof is repeatedly subjected to high pressures or harsh chemicals, the aging of the roof is tremendously
accelerated.

With repeated cleaning, concrete tiles are much more most likely to shift, slip, or break and asphalt shingles are a lot more most likely to turn into brittle and crack. When this occurs, there is a higher
opportunity of damaging the roof basically by walking on it. And when gaps are developed, by natural means or otherwise, and subsequent pressure cleaning or chemical cleaning is performed on a roof, these gaps supply water or the corrosive solutions with a path to the protective roof underlayment, moisture barriers, metal valley underlining, and flashings causing damage that can go unnoticed for years – growing the likelihood of roof leaks and expensive repairs.

WHAT IS THE Very best ALTERNATIVE - PREVENTION?

The safest and most cost-effective long-term strategies will minimize the use of high pressures and harsh chemicals by stressing Preventative Upkeep from the begin. These methods should include periodic roof inspections / maintenance, keeping the roof free of charge of debris, and stopping algae discoloration before it begins. A proper plan of preventative maintenance and algaecide protection will get rid of the want for future cleaning and the potential for damage that comes along with it – giving the homeowner and/or community an aesthetically pleasing roof for the full life of the roof.

Various firms now manufacture merchandise that can inhibit the growth of roof algae for months and occasionally years with each and every application. The most proper algae prevention merchandise are those that have proven results, are guaranteed, particularly designed for roofs, and have EPA approval for use on roofs.
