Pressure Clean Roofs in Palm Beach Gardens, FL

What does pressure cleaning a roof involve?

Pressure cleaning a roof removes the black streaks, algae, mildew and airborne grime that build up on shingle and tile over the years. The work uses low pressure rather than a full force blast, so the granules on shingles and the finish on tile stay in place while the growth is lifted from the surface. A cleaning treatment breaks down the organism, and a low pressure rinse clears it away without driving water under the roofing. Roof cleaning prevents the algae from holding moisture against the material, which can shorten the life of a roof and leave dark streaks that show from the street. It is needed when streaks appear across the slopes, when a roof is being readied for sale, or as part of a full exterior refresh. The work calls for someone who understands the difference between a roof and a driveway, since the wrong approach can damage the roof.
