How Much Does Roof Power Washing Cost?
Roof power washing is a process that involves the use of high or low-pressure water to remove dirt, algae, and other forms of pollution from a home’s roof. It can be done on multiple levels, including flat, pitched, and even on angles. If the roof has a tar or gravel on it, you’ll want to use a chemical wash, and wood-shingle roofs and siding should be treated with a zinc oxide application. In this article we’ll discuss “how much does roof pressure washing cost“.
Low-pressure cleaning is cheaper than high-pressure cleaning
One of the best ways to keep your home looking great is to make sure your roof is in top condition. Cleaning it can help prevent costly repairs. However, some materials such as slate and metal roofs are more susceptible to damage when pressure washing.
If your roof is made from asphalt or concrete, you may be able to safely wash it yourself. But if it is made from metal, you’ll need to hire a professional. You’ll also have to take extra precautions, such as using a soft wash method.
Soft washing is an alternative to power washing that uses less pressure. It’s a good choice for most exterior cleaning projects. Using low-pressure means you’ll avoid the hazards associated with high-pressure, including damaged shingles and slipping.
Tar and gravel roofs are best-suited to a chemical wash
Tar and gravel roofs are the most cost-effective and durable flat roofing options. They also offer excellent protection from the elements. However, these roofs do require regular maintenance. If you are planning to install a tar and gravel roof, you will need to know how to properly care for it.
The first step to repairing a tar and gravel roof is to inspect it for cracks or loose areas. These may be indicative of past leaks. You should also check for discoloration. In addition, you should look for signs of structural damage.
You should also note that a tar and gravel roof is very heavy. It weighs anywhere from five to ten pounds per square inch. This added weight can strain the underlying substrate and cause significant damage.
Wood shingle roofs and siding
While most wood shingle roofs and sidings aren’t designed to take a beating, a well-maintained system should last you a good many years to come. Keeping the old gal clean isn’t cheap, but it’s not impossible. Depending on the material, the average shingle can last about 20 to 25 years if given the right treatment.
A professional will be able to tell you which is the best option for your particular situation. If you don’t have the budget to replace your existing wood with a high-end material, you can try a more cost-effective solution like composite materials or rubberized coatings. Of course, the cost of installing such materials on your roof isn’t cheap, so it’s probably wise to shop around for the best price.
Zinc oxide application
Zinc oxide application is a popular choice for those with roofs that are prone to growing moss. The average cost of zinc oxide application is around some cents per square foot. These types of applications are usually done in a chemical solution, which will kill any algae or lichens on the surface. However, these methods may damage weak tiles and leave debris behind.
If you don’t want to use a chemical solution, you can also apply zinc powder to your roof. However, this is not a permanent solution and will need to be replaced every few years. For best results, zinc strips are recommended to install along the ridge of the roof. When rainwater hits these strips, the zinc particles will inhibit moss growth.
