Roofing and delicate components
Asphalt shingles can lose protective granules under excessive pressure. Tile can be damaged by poor access or handling. Screen mesh, old seals, and fragile fixtures may also be vulnerable. Manufacturer instructions should guide decisions rather than a general promise of safe pressure.
Paint, wood, and siding
Weathered paint can peel, wood fibers can be raised, and water can enter behind siding. Chalking, loose joints, and damaged coatings need attention before washing. A lower-pressure process still requires compatible products and careful application.
Even hard surfaces have exceptions
Fresh concrete, decorative finishes, weak areas, and sealers can be harmed by unsuitable cleaning. Pavers and grout introduce further considerations. Concrete-cleaning equipment should not automatically be used on every driveway, patio, or pool deck.
Ask for a surface-specific plan
Tell JFH Softwash what your exterior is made of and identify known damage. Request an assessment rather than selecting a pressure setting yourself. Where a surface is not suitable for cleaning, repairs or advice from the material manufacturer may be the better next step.
Follow material manufacturer instructions and seek an assessment for your home’s actual condition. Cleaning is not a substitute for repairs.
