Your Insurance Company Might Be Inspecting Your Roof From the Sky

How satellite imagery, drones, and AI are changing how insurers evaluate roofs in Texas

Most homeowners don’t think much about their insurance until renewal time. But recently, many have found out their insurance company has been "inspecting" their roof without ever actually visiting the property.

Insurers are increasingly using aerial imagery like satellite and drone photos to review roofs and property conditions. In some cases, homeowners have received letters saying they must trim trees, clean their roof, or replace their entire roof to keep their coverage.

That raises a few obvious questions. Is it legal? What exactly are insurers looking for? And what does it mean for homeowners here in Central Texas?

Insurers have always had the right to inspect

This surprises a lot of people, but it’s not new.

When you purchase a homeowners insurance policy, the company has the right to inspect the property it’s insuring. Traditionally, that meant sending someone to walk the property, photograph the exterior, or climb up to examine the roof. But what’s changed, with the help of modern tech, is how those inspections happen.

Today, insurers can review homes remotely using aerial imagery and even third-party property data. Some companies also rely on AI-powered software to scan these images and flag potential concerns for human review.

From the insurer’s perspective, this process is faster and less expensive than sending inspectors door to door. From the homeowner’s perspective, it can feel surprising to receive a non-renewal notice referencing issues captured from space.

Is it legal in Texas?

Yes.

Texas law allows insurers to use aerial imagery during underwriting, and the Texas Privacy Act permits insurers and their affiliates to use drones for insurance-related purposes such as policy evaluation, claims investigation, and renewal decisions.

Typically, insurers aren’t actually flying drones over your house themselves. Instead, they rely on imagery collected by satellites or third-party aerial imaging companies that maintain large databases of property photos.

But whether it's Google Earth or companies like CAPE Analytics that boast covering "99.6% of the U.S. population," the result is the same: insurers can evaluate the visible condition of a home’s exterior, including the roof, without ever visiting the property in person.

Why insurers focus on roofs

Roofs drive a large share of insurance claims. Especially in Texas, where hail damage occurs 68% more often than in the next closest state.

Damage to a roof can lead to leaks, water intrusion, structural damage, mold growth, and expensive interior repairs. Because of that, insurers pay very close attention to roof condition when evaluating risk.

Aerial imagery systems often flag things like:

Black streaks on roof shingles
Possible algae or organic growth
Tree limbs touching or hanging over the roof
Debris buildup
Missing or damaged shingles
Visible signs of aging or deterioration

The challenge is that aerial imagery doesn’t always tell the whole story. From overhead, a roof with cosmetic staining can look very similar to a roof that is actually deteriorating. In some cases, the images being used may also be outdated or unclear.

That’s why homeowners sometimes dispute these findings and provide updated photos or inspection reports.

This is common in Central Texas

Across San Marcos and Central Texas, our climate creates ideal conditions for roof staining and organic buildup.

Heat, humidity, shade from trees, and airborne pollen all contribute to dark streaking and growth on shingles. Many homeowners describe this as mold, though it often includes algae, mildew, and other organic buildup.

To be clear, this type of staining is extremely common in humid climates. However, from an aerial photo it can still appear to be neglect or roof deterioration to someone reviewing the property remotely. An underwriter looking at an overhead image isn’t standing in the yard inspecting the roof closely. They’re simply scanning for visual indicators that might suggest higher risk.

No reason to panic

Learning that insurers can inspect homes from above sometimes makes homeowners uneasy. While insurers have always evaluated properties, sky surveillance hits differently than an in-person visit.

Thankfully, the practical takeaway is straightforward: Visible exterior maintenance matters more now because it’s easier for insurers to spot potential issues.

That doesn’t mean every roof with dark streaks will cause a problem. It just means it’s wise to stay ahead of obvious maintenance concerns.

What homeowners can do

Treat roof maintenance the same way you would any other part of the home. A few simple steps can make a big difference, like removing debris and trimming branches away from the roof, and paying close attention to visible streaking or buildup.

Additionally, be sure to keep records of any roof repair or replacement work you have done.

If you receive a notice from your insurer referencing roof conditions, don’t ignore it. Take current photos, gather any documentation you have about the roof, and respond quickly. Providing updated information can often resolve the issue.

Where roof cleaning comes in

One thing we see regularly is that a roof that looks “bad” from a distance often isn’t structurally damaged—it’s just dirty.

Algae staining and organic buildup can make a roof appear much worse than it actually is, especially in aerial photos. Cleaning those surfaces can dramatically improve the roof’s appearance and help homeowners stay ahead of maintenance concerns.

In a humid climate like Central Texas, routine exterior cleaning is simply part of maintaining a home.

If your roof is showing black streaks, algae, or visible buildup, addressing it now can help protect both the appearance and condition of the roof, as well as reduce the chances of questions or issues during an insurance inspection.

The Dirt in Your Driveway Might Be ALIVE

October 1, 2026

When you look at your driveway in need of some cleaning, you probably only see dirt. Maybe some grime, a few stains, and that weird dark stuff that always seems to appear after it’s been raining. Nothing particularly exciting. It’s why we have the saying “as boring as dirt.” Except some of that “dirt” may not be dirt at all. Your driveway could be hosting a tiny, thriving ecosystem of un-boring and actually terrifying life. That Black and Green Filth Is Growing Hard surfaces are surprisingly good real estate for certain organisms. The Royal Horticultural Society notes that algae, lichens, liverworts, and moss commonly establish themselves on places like driveways, paths, patios, decking, and steps . So that greenish film or fuzzy-looking buildup you’ve been mentally filing under “gross driveway schmutz” may not be composing epic operas or trying to establish communication with you, but it very well might be alive. Algae, for example, can form a thin, powdery film over everything from concrete to paving, stone, tarmac, and decking. They particularly enjoy wet conditions, with growth accelerating in shady spots where air doesn’t circulate particularly well, which describes the bulk of Texas driveways. The RHS also notes that these buildups can become especially noticeable after wet winters. Sometimes, the “Dirt” Gets Slippery Here’s why this isn’t merely an aesthetic problem. The organisms growing on your driveway aren’t necessarily damaging the surface itself. Algae and lichens etc. don’t actually pose a threat to your driveway itself. However, they can make surfaces slippery, which is a great feature in skating rinks and the like. But it’s considerably less charming when the surface in question is somewhere people walk. Researchers at the University of Venda have also examined algae colonization on brick pavement and its relationship to slipperiness. Their study found that bacteria, cyanobacteria, and algae are capable of colonizing not just flat surfaces, but any kind of outdoor impermeable structure since those trap water and nutrients that encourage growth of microorganisms. The study also found that the slippery effect of algae is due to their production of a gluey, gelatinous substance known as mucilage that becomes like a slippery gel in water. So, the innocent-looking dark patch beside your garage may not just be an ugly stain. Under the right conditions, it can be part of a living layer that makes the ground beneath your feet a potentially costly health hazard. Thankfully, You Don’t Need a Biology Degree to Deal with the Problem You don’t need to identify every specific microscopic driveway squatter before dealing with the problem. Physically removing established growths with stiff brushing etc. will sufficiently deal with the issue but pressure washing has the added benefit of being quicker and easier on your back. But it should be left to professionals. Pressure washers are very fun to handle. So much so that there are many pressure-washing video games out there. But if not handled correctly, a pressure wash will not address the problem of moisture, shade, and poor drainage, and in no time, the algae and other microorganisms will return. You don’t need to panic but if your concrete is developing green, black, slimy, or mossy buildup, it may be time to stop treating it like ordinary dirt, and start dealing with it like an infestation that’s best handled by pros. A professional exterior cleaning can remove the visible “living dirt” buildup and restore a surface to its original condition. Because your driveway is supposed to be where you park the car, not where algae, moss, and other microscopic pests decide to establish a vacation home.
