Do You Need Your Roof Cleaned?

Do you see black, streaky stains on your roof? Is mold or moss starting to spread across your shingles? If these issues are creeping up on you, a roof cleaning might be just what you need to maintain the health and aesthetic of your home. 

Stains on a roof are generally algae, which gets carried by wind or birds from roof to roof, and may not be visible until there is enough moisture, heat, and humidity for it to grow and spread. Homes that aren’t properly insulated and ventilated are also susceptible to the problem because they retain moisture a lot more than houses with proper airflow.  

If you’re worried that your stained or moss-covered roof is doomed, don’t panic just yet. While too much moisture is a major problem that needs to be dealt with, algae that is deposited externally from the elements can be removed with a simple cleaning. That being said, the first thing you want to do is find out if your issue is cosmetic or something more serious. 

Ideally, I recommend that a homeowner gets a roof inspection at least once a year and the late spring is one of the best times to do it. During an inspection, a roofing professional will check the entire surface area for shingle deterioration or damage, cracking around the flashing, and will also ensure that water is draining properly through the gutters and downspouts. Something as simple as debris build-up can void the warranty of a roof, so it’s well worth having an expert come and take a look. They will be able to tell you if your stains are something that can be taken care of with simple cleaning or if there is a bigger picture issue.

To get rid of discoloration, mold, and mildew, we use a professional roof cleaner that adheres to the growth but doesn’t harm the roof or any vegetation below it. A roof cleaning takes a few hours depending on the size of the area and one application does the job without the need for pressure washing which can damage the shingles. 

Working on a roof is a very dangerous job and I never recommend for a homeowner to do a task like this themselves unless they are very comfortable on a ladder and with heights. No home maintenance task is worth a trip to the emergency room.

Is It Time For A New Roof?

When was the last time you checked out your roof? If it has been a while, now is the time to do it. Most roof problems are caused by snow, wind, rain, and ice, making spring the perfect season to assess your home for damage. 

When you look at your roof, what do you see? Are the shingles intact? Is any part sagging or discolored? Are there dark spots on the outside or ceiling cracks and yellowing on the inside? These can all be signs of a deteriorating roof. But how long is a roof actually supposed to last, and is a new roof worth the investment? Here are some things to think about when it comes to roof replacement.

1. How old is your roof? Roofs generally last about 20 years, and the reason I say generally is that the life of the roof depends on how it was installed and if it has proper insulation and ventilation. If a roof is done correctly, it can often last longer than 20 years. If you don’t know, it’s worth finding out, especially if you recently purchased your house or are thinking about purchasing one.

2. Are your shingles curling, splitting, or falling off? This could be due to age and general wear and tear. If this is happening, your roof will be much more susceptible to leaks, which can cause major problems both inside and out. Take a look at where your downspouts deposit onto the ground. If there are lots of granules, that’s a sign of shingle deterioration.

3. Do you see moss or mold growing on your roof? This is a problem that could be fixed with a simple roof cleaning, or it could be a sign that you have rotting wood and damaging moisture trapped under the shingles. A simple inspection will tell you if it’s a quick cosmetic fix or something more complex that needs to be repaired.

4. Are there yellowish-brown stains or cracking on the ceiling inside the house? This is likely water damage coming from the attic. This is a problem you don’t want to ignore as water is likely already entering the home and the problem won’t fix itself. 

Many remodelers will do a roof inspection for free, so if you’re unsure about how your roof is holding up, consult with an expert. I always tell the homeowners how long I think their roof will last based on its current condition and the external environment. The number one reason roofs don’t make it through their warranty is because of poor ventilation and insulation, which lead to premature roof aging and rot. If you’re dealing with a good roofer, they will explain all the options available to you so don’t be afraid to ask questions.

Ventilation is Key To Your Home's Health

I’m not shy about educating my readers on the importance of proper insulation in a house. But even if you’re one of only 20 percent of homeowners I meet with the right amount of insulation, chances are you’re still missing a key piece of the puzzle. The critical component is ventilation and not enough of it can be harming both your home and your personal health in more ways than you think. 

In the winter, we crank up the thermostat, sending more heat into our homes than any other time of year. We all know that heat rises, which means a lot of what we’re pumping into the house will quickly find its way through the ceiling and into the attic. Think about when you’re in a car and the windows fog up. What do you do? Usually, you’ll increase the airflow either by using the vents or just cracking a window. A house works much the same way, except that if you don’t have air flowing inside the attic, the heat and moisture just gets stuck there. If the attic is very warm, that moisture will develop into mold and mildew which can feed on your insulation and rot the wood. If the attic is cold enough, the moisture will freeze into little domes or even icicles until the temperature rises enough for the water to thaw and then be absorbed into all the places that it shouldn’t. Neither is a good scenario.

So what’s the best way to protect your home? Start by investing in a humidity gauge that measures water vapor in the air. A comfortable humidity reading is 30%-60%, but 45%-55% is an ideal level to maintain. If you’re seeing higher than 60% humidity in any area of your home, it’s going to be susceptible to mold, mildew, and bacteria growth.

Remember, attic ventilation allows your house to “breathe” so you want to balance your intake and exhaust to ensure that what is coming in is going out equally. The best ventilation system will include soffit vents that are installed underneath the overhang of the roof and take in the air and ridge vents that are installed at the top of the roof for the hot air to escape. For this method to work efficiently, all louvered vents must be sealed off and you have to ensure that your insulation isn’t blocking the airflow. Believe it or not, most roof manufacturers will void the warranty if a proper ventilation system is not installed. Luckily, new roofing technology enables contractors to add intake ventilation directly into the roof as opposed to using soffit vents, so if you’re in the market for a new roof, be sure to ask for that option. 

It’s important to note that homes have different characteristics and what works well for one may not work well for another. With the right balance of air, homeowners can optimize their roof and maintain the overall health of their home and their families. Remember, it’s always a good idea to get advice from a professional before taking on a big remodeling project.
