A warm, sunny day is the best time of year to pressure wash your house. The warm sun will be able to dry out the house after washing. You should also consider pressure washing your home after the rainy, storm season has passed. Depending on where you live, this might be in the spring, summer or early fall.

Yes roofs can be cleaned, and yes, it’s a real thing. Roof cleaning may actually be a wise investment to prolong the life of your roof. Overgrowth of moss, grime, lichen or algae can all shorten the life of your roof. If you have black streaks growing on your roof, they are likely caused by gloeocapsa magma algae spores that have landed on your roof and taken up residence. Once the algae has grown into streaks, the organism has usually been growing for several months and it’s high time to have it removed.

Pressure washing a house tends to take anywhere from 30 minutes to several hours. The larger the house, the longer it will take. It may also take an additional 15 to 30 minutes of setup time and pack time, and some time may be required to switch between applying the cleaning chemicals and rinsing them off. 

You can safely use a pressure washer on a number of different surfaces, including your home’s exterior, siding, driveways, rooftops, sidewalks, patios and more.

It can also be used to clean grills, outdoor furniture, cars and trucks, boats, bikes, fences and decks. You can generally clean any hard outdoor walking surface, including asphalt, concrete, brick and pavers with a pressure washer.

However, it’s possible to damage your property — especially wood and vinyl surfaces — if you don’t use the pressure washer correctly. Consider hiring a Handyman Vet pro if you don’t have experience using the equipment and selecting the correct PSI.
