Roofs - Washing vs Replacing

Even if your roof is looking unsightly, it might not be time to replace it. A thorough roof cleaning can give your roof a fresh look and add years to it’s life. Every year, people choose to replace their roof when in reality, a thorough roof cleaning would have saved them thousands of dollars and added years to the life of their roof. So, if you aren’t sure about what to do for your roof, consider the options before you make a decision.

If you are missing shingles, your shingles are more than 25 years old, there are no granules left on your shingles, tabs are flipping up or if the shingles are brittle, then yes, you likely need a roof replacement. However, just because your light colored roof is now streaked with solid black or has moss growing on it does not mean that you need a new roof. Rather, it most likely just needs cleaning.

1. Give your house a polished lookA thorough cleaning will take off all black stains, sometimes called magma, and moss, bringing your roof back up to a like-new appearance. Professional roof cleaners often use a biodegradable chemical that has a residual effect that will continue to keep your roof clear of these blights for a minimum of one year.

2. Protect your roof from damageFor continued protection, you can reapply the biodegradable chemical cleaner every 18 to 36 months, but you don’t have to wait until you see problems to clean your roof. This process is also a preventative one and by applying it, you'll avoid ever seeing destructive and costly moss on your roof and even extend the life of your shingles.

3. It’s cheaper than a new roofSimple roof cleaning maintenance can definitely save you money. An average 900 square foot roof replacement can cost upwards of $5,500 while cleaning that same roof would cost around $260.

4. Keep your roof warranty effectiveMany homeowners don’t think they need to regularly clean their roof because their shingles came with a multi-year warranty, but the manufacturer actually suggests that you clean them. Just like having a 100,000 mile warranty on your car doesn’t mean that you don’t need to change the oil for that long, taking care of your roof will make sure your roof takes care of you.
