Roof cleaning is one of the most important home improvement tasks a homeowner will be faced with — though maintaining a clean roof is for more than simply achieving a better looking home. Here’s TOP five reasons why:

1. Stops roof damage

Roof damage
Roof cleaning stops the damage that nasty organisms do to your roof. These organisms, like lichens, algae and moss are feeding off the organic material in your shingles. Which means, your shingles are their breakfast, lunch and dinner. The more time they have to stay and devour your shingles, the worse things get.

2. Roof cleaning kills algae

On your roof there is algae, lichens and/or moss can eat through your shingles and into your roof deck causing wood rot. When the wood rots, moisture gets in through the cracks and creates an environment hospitable to mold growth. And mold growth in a home can pose health risks to people and pets. Don’t ignore roof stains. With a gentle, eco-friendly wash costly roof repairs can be avoided BEFORE any permanent damage to your roof deck occurs.

3. Lower Energy Costs

Clean tile roof reflecting heat
A roof covered with algae, moss etc. is no longer able to efficiently reflect sunlight. The algae covered shingles absorb heat, thereby super-heating your attic and increasing your cooling costs. A soft wash safely, gently, and completely removes the staining, restoring your roof back to its natural health and efficiency.

4. Avoid Roof Replacement

Having your roof cleaned is the cost saving alternative to premature re-roofing. There is absolutely no need to prematurely re-roof when your roof can look like new again for a fraction of replacement costs.

5. Restore Beauty

Restore the beauty of your home. A dirty roof detracts from your home’s curb appeal. You clean your siding, porches, and walkways. You may even apply weed control and fertilizers to spruce up your lawn and garden. But if you ignore those ugly roof stains, no matter what else you do to improve your home’s exterior, those stains will be the main focal point of your home’s exterior. And, if you are hoping to sell your house, roof cleaning is a must!

FAQ - Roof cleaning services

Does cleaning your roof damage it?

Yes, roof washing can damage your roof if done INCORRECTLY, which means you need to have the right training to know your roof’s material needs, the types of soils on the roof and the right equipment to execute. For example, a metal roof might allow a high pressure water without damaging but a shingle roof would easily stripped and severely damaged. However, to avoid damaging your roof in all circumstances, we use a low pressure water and a great soaping process that we call softwashing.

To get right to the point, residential home pricing starts based on the square foot size of the roof and ranges from $500 to $1500. From that baseline, prices increase based on the number of stories of the house (the difficulty of reaching the roof), the soil level (amount of soaps/time/etc needed to get it clean), the difficulty to walk on the roof (the pitch) and what material type is the roof made of (similar variables as soil level). Ultimately, the roof must be inspected for an accurate price.

Softwashing is a process of using low pressure water pumps and a special combination of commercial grade soaps. Certified softwashing systems use water-based, biodegradable chemicals that emulsify dirt and grime as well as sanitize the surface they are bonded to. The treatment lasts four to six times longer than pressure washing and uses one third of the water.
