Q & A

Answers to commonly asked questions from the experts on Thumbtack.

Why do I need to clean my roof?

Over time, algae, moss, lichen, dirt and even salt (if you’re near the ocean) can build up on your roof. These buildups can affect the look and function of your roof unless removed. The buildup of organic materials such as moss on a shingle roof can prevent water from sloughing off as it normally would. Trapped water can rot the roof or cause early deterioration of your shingles. Even if you don’t have a shingle roof, moss and lichen absorb water, and that wet material adds weight and stress to your roof — as well as providing a home for insects and other pests, and collecting dirt. For reflective, cool roofs that redirect heat away from the home, algae and moss growths can hamper their ability to deflect the sun, which can affect utility bills. Visually, moss, dirt and algae growths on a roof can have a negative effect on perceived home value and curb appeal. For example, black algae streaks on your roof may cause a potential homebuyer to assume that the roof might need repair or replacement, when it only needs to be cleaned.

Why is it important to clean your gutters?

Rain gutters, those easily-forgotten trenches that hang off the edge of your roof, protect your roof, walls and foundation from excess rainwater. When they get clogged with leaves, sticks and other wind-blown debris, they can no longer direct water away from your walls and foundation, and may become homes for pests and insects. They also become heavy enough to pull away from the house, preventing proper rainwater drainage and spoiling the appearance of your home. Experts recommend inspecting and cleaning your gutters twice a year, once in spring and once in fall, as part of your regular landscaping schedule. Gutter cleaning and maintenance is a fairly easy DIY job for some homeowners, especially on one-story homes. However, professional gutter cleaners have ladders tall enough to safely reach rain gutters, as well as the necessary tools to clean out the downspouts. Most gutter cleaning professionals can also make any necessary quick repairs.

Can a roof be cleaned?

Yes roofs can be cleaned, and yes, it’s a real thing. Roof cleaning may actually be a wise investment to prolong the life of your roof. Overgrowth of moss, grime, lichen or algae can all shorten the life of your roof. If you have black streaks growing on your roof, they are likely caused by gloeocapsa magma algae spores that have landed on your roof and taken up residence. Once the algae has grown into streaks, the organism has usually been growing for several months and it’s high time to have it removed. If you live in a rainy part of the country, such as the Pacific Northwest, there’s a good chance you’ll find moss growing on your roof at some point. The northern part of your roof, as well as any parts that remain shaded all day, will provide a wet, cool haven for moss to flourish. Unfortunately this water-absorbing moss can damage your shingle roof, leading to rot if not removed. Beyond roof health and function, a clean roof can boost your curb appeal and potentially boost your home’s resale value. The national average for roof cleaning costs ranges between $270 and $350, although prices can be higher depending on how large your roof is, how steep your roof is, and what type of cleaning is necessary. Typically pros use either a pressure wash or chemical wash (made with a concentrated bleach solution) to remove algae, lichen, moss and dirt.

How much is commercial window cleaning?

The national average cost to clean windows is $120-$170. Typically, window washing for commercial spaces costs less per window than residential window washing, but has a higher overall price because the greater number of windows. Commercial window cleaning companies may charge a standard rate per window — for example, $3 to clean the exterior only, with a higher rate of $4 or $5 to also clean the interior. There may be an additional charge, such as an extra $1 per window, for scrubbing off water stains or deep-cleaning window tracks. Double-hung windows require more labor and will therefore cost more to clean. Companies may charge a flat rate, such as $8 per double-hung window or $9 per French door, to account for the added work. Building height will play a factor in window washing costs. Standard cleaning for one- and two-story buildings will typically stay within the same range, but cleaning high-rise windows may entail special safety permits and equipment, which would increase costs. Your location will also affect window washing costs. Smaller towns and areas with a lower cost to do business will have lower window cleaning rates than large cities.

How often do you need to clean your gutters?

Gutter cleaning and maintenance is an important part of keeping up a home. Not only are clogged gutters unsightly, they can also lead to water damage in the house’s walls and roof. The best way to prevent that is to clean your gutters at least twice a year — experts recommend making it part of your spring cleaning and fall landscaping schedules. In the fall, trees lose their leaves and, in the spring, release seedpods and flower petals, all of which tend to end up in rain gutters. It’s a good idea to also have a professional gutter cleaner clear out your downspouts, too; clogged downspouts can make gutters backup and overflow.
