No matter what types of metal siding you are cleaning, you should be able to clean them using the same processes you use for aluminum siding. Steel siding and aluminum siding both need cleaning about once per year. You can clean metal siding or aluminum siding without a pressure washer or with one.

A self-etching primer is the best option for aluminum siding. These are specifically designed to bond with bare metals, among other surfaces, leading to better adhesion and corrosion resistance. An oil-based primer is a good alternative if you can’t find a self-etching primer.

You should restain or refinish your home's cedar siding every three to seven years to maintain its appearance and ensure maximum protection. The precise frequency depends on several factors, including your local climate, the siding's exposure to severe weather like direct sunlight, rain, and wind, the quality of the initial stain application, the type of stain used, and the condition of the wood.

Homeowners in harsh climates with high humidity and significant direct sunlight should plan on restaining every three years, while those in milder locations can wait up to seven years. For the longest-lasting protection in particularly harsh environments, consider using an opaque stain.

If you're looking for a lower-maintenance alternative, vinyl or aluminum siding are options to consider. Although their installation cost may be higher, they don't require as much upkeep over time, which can provide more value, especially in areas with excessive rainfall or high humidity.

There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.
