Somerset Roof Cleaning
Thank you for finding our page. Stains on a roof are alive and contagious. Anything less than full sterilization simply will not suffice. What does that mean? Let’s look into the process and find out what exactly is eating your roof.
The Process
Bacteria called Gloeocapsa Magma causes the black streaky staining on roofs. These bacterium form a UV repellent outer coating that needs to be dissolved in order to penetrate and kill the organism inside the outer shell. A detergent with the proper ph can dissolve the outer shell allowing the growth (black stains) to simply dissolve in a manner that creates a fully sterilized surface.
Sodium hypochlorite (bleach) is the safest detergent base which is biodegrade yet outperforms to complete the objective. SH is made from salt and biodegrades back to salt. The largest purchasers of SH are local municipalities the inject into tap water to prevent water born viruses.
Perfectly calibrated detergents applied to a roof can dissolve this staining rendering the roof completely sterile. Full sterilization allows the roof to stay clean for an extended period of time. Any roof can benefit from soft wash including slate roofs, cedar roofs, barrel tile as well as asphalt shingle.
Roof Moss Removal
The approach to moss removal is slightly different since the root system develops into the roofing shingle. To put it simply there is rooted vegetation on the shingle. Much of it can remove fairly easy while deeply rooted moss can require stiff scrubbing or pressure washing.
Aggressively scrubbing or pressure washing a roof can dislodge large amounts of roofing granules and shorten the life of a roof. The application of a properly calibrated detergent can kill moss as the moss insuring an extended level of clean. The process of detergent cleaning refers to soft washing.
Moss will not dissolve like black staining but it will die immediately. After the dead vegetation dries out it will detach from the roof and wash away with rains. The process is slow but guaranteed to work.
Power Washing Somerset NJ
The old school days of blasting pressurized water at every stain are over. Detergent technologies far exceeds the desire for blasting water on delicate surfaces. Organic staining such as mold, moss, mildew and algae require a specific staining where as non-living chemical reaction stains require other types of detergent. Rust, lime, oxidation and water stains fall into the chemical reaction league.
Any surface can benefit from soft wash such as vinyl, aluminum, stucco, EIFS and even painted sidings. Patios, fences, decks, gutters and windows gain a hospital level of clean from a detergent soft wash.
