Q: Can I wash my own roof?

• <div><p>It is possible to wash your own roof, but we don&rsquo;t recommend it. First, getting up on any roof is dangerous without proper safety equipment, especially if wetting a metal roof and making the surface slick. Additionally, it&rsquo;s easy to damage your roof or force water between roof seams if you <a href="https://www.angi.com/articles/can-roof-cleaning-extend-life-my-shingles.htm">use a power washer</a>, which can lead to property damage. Hiring a professional roof cleaner will save you time, keep you safe, and ensure that your roof looks new again without damaging it in the process. Plus, roof cleaning is a relatively affordable home improvement project.</p></div>

Q: How long after power washing can you paint?

• <div><p>You&rsquo;ll need to wait until the surface is completely dry, which can take anywhere from 24 to 48 hours under optimal conditions. The waiting period depends on several factors, including the type of siding and the weather conditions. Trying to paint before the surface is completely dry can trap moisture under the paint, leading to bubbling, blistering, and mold growth.</p></div>

Q: How do you prep a surface for pressure washing?

• <div><p>It depends on the type of surface, but if you&rsquo;re preparing to <a href="https://www.angi.com/articles/how-to-pressure-wash-driveway.htm">pressure wash a driveway</a>, you&rsquo;ll start by using a broom or leaf blower to get rid of dirt, leaves, and other debris. Then, move any nearby items (like outdoor furniture and potted plants) and cover in-ground plants with a tarp or plastic sheet. After that, you can apply degreaser spray or another pretreatment solution to any stains and scrub them with a stiff brush before pressure washing.</p></div>

Q: Do I need to winterize my pressure washer, and what happens if I don't?

• <div><p>Whether you need to winterize your pressure washer depends on where it will be stored. If it's kept in a location where temperatures could drop to freezing, any liquid left in the water pump can freeze, expand, and cause severe damage to the machine. To prevent this, you can add antifreeze to the pump. While emptying the machine with compressed air is an alternative, it can be a tedious process and may not remove all the liquid. If you can store the pressure washer in a relatively warm place with no risk of freezing, you won't need to add antifreeze. However, regardless of storage conditions, it is good practice to empty the gas chamber and refresh the oil before storing it for the winter.</p></div>

"We called Southern Grace Exteriors to inspect the roof of a rental property we own in Hilton Head, SC. Our management company said we needed a new roof .... and that they could do it quickly for a HUGE price. We decided to get a second opinion and called Southern Grace. They showed up on time, climbed up on the roof with me and told us that our roof was just fine - probably had 10 more years left. They also said that whoever told us we needed a new roof didn't know what they were talking about. Honest and straight forward - a refreshing change to the norm for many contractors.

Pressure Washing questions, answered by experts

You should avoid using a pressure washer on any surface or item that could be damaged by the high-pressure spray, as some materials are too delicate to withstand the force.

Key items and surfaces to avoid include:

Electrical Components: Never pressure wash electrical systems, as water can cause short-circuits and create a safety hazard. This includes utility meters, breaker boxes, electrical outlets, generators, and HVAC or air conditioner units.
Delicate and Fragile Materials: Fragile items can crack, shatter, or be stripped by the pressure. Avoid pressure washing windows, glass, light fixtures, shingled roofs (especially asphalt), and stucco.
Painted, Stained, or Sealed Surfaces: Unless your goal is to strip the finish, do not pressure wash painted surfaces, stained wood (like decks), or anything with a protective seal that could be stripped away. Be especially cautious with older surfaces that may contain lead paint.
Soft Woods and Certain Decking: Delicate surfaces like softwood, composite decking, and antique or wooden patio furniture can be etched or damaged. If you must wash wood, use a lower-powered pressure washer with a wide-angle nozzle to prevent damage.
Living Things: Never use a pressure washer on people, pets, or plants. The force can cause serious injury and will destroy landscaping.
