Should Your Roof be Replaced or Cleaned?

You may have recently noticed some dark streaks on your shingles, and may be considering replacing your roof.  Before you add that massive expense, you may want to consider having your roof professionally cleaned.

What are some ways to know if your roof does need to be replaced? Well, examine your roof and see if some or all of these things are true:

  • cupped or bowed shingles
  • missing shingles
  • bald shingles where the granules have been removed over time
  • cracked shingles


If you’re thinking of replacing your roof because it is discolored or has massive black streaks or has so much moss and lichen on it looks like carpet…. well then I’ve got good news for you.  You may not need to replace your roof.  You may just need to have it professionally cleaned. Here in Greensboro, Winston Salem, Clemmons or the Lexington, North Carolina, area, we do get a lot of dampness and humidity. That all can hasten the growth of organic matter on your shingles – such as bacteria, algae, mold, lichen and moss. The good news that just like anything else; just because it’s dirty doesn’t meant it has to be replaced; or that it needs to stay dirty – you can clean your roof! A lot of people don’t realize that, but you can clean your shingles and have them look like new again. To read more about our roof cleaning process, check out our web page on roof cleaning here:


Oh yes.  In fact, check out this chart from showing you the average cost for a roof replacement in our area (here around Greensboro, North Carolina, Lexington, NC, Winston Salem, NC, Salisbury, NC, Oak Ridge, NC, Kernersville, NC – basically the Piedmont and Foothills of NC):

So the typical cost for our area is $4607 – $8637.  However, having your roof professionally cleaned will cost you about 1/10th of that cost!


Yes!  Your roof is, in most cases, designed to last 20 – 30 years.  However, if you have lichen or moss or nasty black algae growing on your roof, the lifespan of your roofing system can be considerably less.  Moss and lichen actually create root systems that wreak havoc on your roof, causing permanent damage, leaks or even health concerns.


Two words:  curb appeal.  You work hard.  You’ve invested alot of time and money in your home or business – so make it look amazing!  The first thing people see when the ride down your street or pull into your driveway is your roof.  So show off your home! Make that roof shine! Are you selling your home or about to put it on the market?  You want the 1st impression a potential buyer to be magical!  A dirty roof scares off potential buyers as they think they’ll need to replace it.  Clean your roof prior to putting it on the market and watch that SOLD! sign go up.

In addition to curb appeal, having your roof cleaned could also improve energy costs.  If you roof is covered in black algae, moss or lichen, then your shingles aren’t reflecting the sun’s heat… and that will increase the cost of your energy bills.  

Protect your family from potential health hazards.  If mildew and mold start growing on your roof; or moss or lichen break down your shingles, causing leaks, then the interior of your home could get moldy too, potentially causing health problems for you or your family.
