Miami Pressure Washing & Roof Cleaning specializes in tile roof cleaning with a system that maintains the finish of the tile and helps prevent algae re-growth.
In Miami roof cleaning is a fact of life as “roof algae” thrives in warm climates. It is that algae which turns roofs, and everything else, almost black over time. A clean roof enhances curb appeal and energy efficiency while extending the life of the roof. The main problem is this algae is usually back in a year or two after a typical cleaning. Repeated pressure washing will damage a roof’s finish when performed on an almost yearly basis to remove re-growth. Look around Miami and you will notice roofs that have faded from being pressure-washed too much.
Roof Cleaning SYSTEM
Miami Pressure Washing & Roof Cleaning (MPRC) specializes in tile roof cleaning and uses a cleaning and sealing system that maintains the finish of the tile. The sealing process works with the sun’s ultra violet rays to prevent algae re-growth. The roof is pressure-washed once.Then it is treated.
In a few years or more when algae returns, simply treat it again – much easier on the budget and your roof’s finish. MPRC includes a two-year warranty with all roof treatment applications.
In most cases roofs turn black due to the presence of living organisms like mildew, mold, fungus, bacteria or algae. With our sub-tropical weather that’s why roof cleaning in Miami is so necessary. However, while power-washing will remove the stains, repeated cleanings will render roof tiles more porous, allowing for more rapid regrowth, and eventually destroy a granulated system like a shingle roof or most flat roof systems.
When it comes to roof cleaning, not all roofs are the same. Here are the most common tile types and how we approach each type to provide you with the best roof cleaning service.
Clay tile roofs are generally more fragile to walk on due to their low Water Absorption Rate. That is also why they stay clean longer. They are very dense and therefore brittle. MPRC staff are trained to protect your tile and understand how to avoid damaging your roof. For example, it is naturally better if cleaners are lightweight and know how to properly walk on a tile roof.
Concrete tiles are stronger but can still break if precautions are not taken and come in three profiles – flat, double-S and barrel. Naturally, flat tiles are easiest to clean. Concrete tile can be color-through or painted. Painted tile are damaged with repeated pressure cleaning, eventually exposing bare concrete. Color-through have oxides added to the mix for color. Repeated cleanings make them more porous.
Shingle roofs feature colored granules adhered to the fiberglass. Repeated pressure-cleaning will remove the granules and destroy the shingles. A one-time cleaning is recommended, using moderate pressure to avoid damage, and spray treatments going forward.
The same rules apply to flat roofs which also feature a granulated surface. These flat roofs should only be cleaned once in advance of a roof coating application.
Metal roof cleaning is all about using compatible chemicals and moderate pressure to protect the finish. Metal roofs are the most time-consuming of roof cleaning applications.
