Signs You Need A Roof Cleaning

Have you ever glanced up at your roof and noticed unsightly black streaks or patches of moss? It's not just about aesthetics – your roof might be trying to communicate something important about your home's health.

Dark markings on roof shingles are often signs of algae growth. Spores hitch a ride on the wind and, once they find a cozy spot on your roof with ample sunlight, warmth, and moisture, they start throwing a green party. Homes that skimp on insulation and ventilation are particularly prone to this issue, as they tend to hold onto moisture like a sponge. Before you know it, you've got a roof that resembles a botanical garden gone rogue.

Now, before you start worrying, it's essential to determine if your roof's issues are just skin-deep or if there's a deeper concern brewing. Think of it like a check-up for your home – ideally done at least once a year, preferably in late spring when nature's in full bloom. A roofing professional will meticulously inspect every nook and cranny, checking for signs of shingle deterioration, flashing cracks, and ensuring your gutters aren't staging their own mini waterfalls. Even something as seemingly trivial as debris buildup can spell trouble and potentially void your roof warranty. So, it's wise to call in the experts and let them work their magic.

Now, if your roof's stains are merely cosmetic, fear not – a roof cleaning session can work wonders. It's a relatively quick process, typically taking just a few hours, depending on the size of your roof. Plus, there's no need for aggressive pressure washing, which could harm your shingles. Instead, professionals use specialized cleaners that tackle the growth without harming your roof or the greenery below. And let's be real here – climbing onto your roof is not exactly a walk in the park. Leave this task to the pros unless you're a ladder-climbing aficionado with nerves of steel. Safety first, always.

But what if those stains are creeping into your attic space? Well, that's a red flag waving frantically in the breeze. It could mean your home's airflow is about as efficient as rush hour traffic. In such cases, it's wise to have a chat with a roofing expert about insulation and ventilation upgrades. Mold and algae setting up camp in your attic aren't just unsightly – they can also wreak havoc on your indoor air quality, which is especially concerning for vulnerable folks like the elderly or those with respiratory issues. Don't procrastinate on this – nip it in the bud before it becomes a full-blown issue.

Put Roof Cleaning on Your Spring To Do List

A roof covered in black, streaky stains or moss growth could be much more than just cosmetically displeasing. It can also be a sign that your house can’t breathe properly. 

Algae spores get carried by the elements and once they get enough light, heat, and moisture, they begin to grow and spread. Homes that aren’t properly insulated and ventilated are most susceptible to the problem because they hold onto moisture a lot more easily than houses with proper airflow.  Once algae begin to grow on a home, it will spread very fast, resulting in black streaky staining or thick moss. 

If you have one of these problems, the first thing you want to do is find out if your issue is cosmetic or something more serious. Ideally, a homeowner should get a roof inspection at least once a year and 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, and cracking around the flashing. They will also ensure that water is draining properly through the gutters and downspouts. Something as simple as debris build-up can void the roof warranty, 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 more significant issue.

If your staining is cosmetic, 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. A roofing expert will use a professional cleaner that adheres to the growth but doesn’t harm the roof or any vegetation below it. 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. 

If your roof staining is showing up in the attic, your home is one of many in this area that doesn’t have the right airflow and you may want to discuss insulation and ventilation with a qualified roofing professional. Mold and algae in the attic can easily start to affect the air quality in your home, which is especially worrisome for elderly adults, young children, and anyone with respiratory issues. If you think your home might be affected, don’t put this problem on the back burner. Talk to an expert right away.
