Find a roof sealer near you

There are several reasons why it’s worth it to hire a professional roofer instead of attempting it yourself. The first is safety. Roofing is inherently dangerous, as a fall from a roof could seriously injure or kill you. Roofers have specialized equipment and training to help prevent accidents.  

Next is experience. Roofers know how to spot problems (leaks, missing shingles, moss or mold growth, etc.)  in your roof that could potentially save you from costly repairs down the road. 

And finally, roofers save you time by getting the job done quickly and with a high degree of quality.

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.

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.

Some of the signs that indicate you need a new roof include cupping, warping and peeling asphalt shingles, as well as cracks on certain shingles. Other warning signs may include:

• Leakage
• Exposed nails 
• Missing granules
• Droopy, sagging roof
• Moss, mold or fungi growth 

A metal roof may need to be replaced when it grows rusty and begins leaking. Tile roofs made of clay, slate or concrete need repairs when cracked. Cleaning and inspecting the roof regularly can help prevent major damage from occurring.

The best roofing material for your home will depend on your budget and what you’re looking for. If you want a roof that has longevity, consider the following lifespans for different materials:

There are a variety of roofing materials available and appropriate for residential applications. When choosing roofing materials, it's essential to consider the look you want, your budget and the climate in your area. 

Asphalt shingles are one of the most popular types of roofing materials because they are affordable and relatively easy to install. They come in various colors and styles designed to last decades if properly maintained. Asphalt shingle roofs also have a higher fire resistance than other roofing materials (like wood shakes), making them an ideal choice for homes in areas prone to wildfires or other natural disasters. 

Metal roofs are becoming increasingly popular because they offer superior durability, fire-resistance and energy efficiency compared to traditional asphalt shingle roofs. They are available in various colors and styles, making them a good option if you want more customization options. Metal roofs also require less maintenance than other types of roofing materials. 

Tile roofs are an excellent option for homeowners looking for long-term durability and multiple style options. Tile roofs can have great longevity with proper maintenance, making them an ideal choice for those who don’t want to replace their roof too often. Tile roofs typically cost more than asphalt shingle or metal roofs, so if budget is an issue, this might not be the best option for you. Keep in mind that tile roofs are often made out of clay or concrete — both of which are durable.

Slate roofs are known for lasting a lifetime, which means you probably won't have to replace this type of roof. Slate is durable, a curb-appeal booster and a favorite among homeowners. Just keep in mind it can get a bit pricey.

No matter which type of material you choose, make sure that you hire a top-rated professional who knows how to properly install your home's new roof. Search Thumbtack for roofing contractors and companies in your area today.

A roof’s lifespan depends on two major factors: the material and how well the roof was installed. Assuming that the roof is installed properly, here’s how long different roofing materials should last:

• Asphalt shingle roof: 20 years
• Metal roof: 50 years
• Slate roof: 100+ years (lifetime)
• Clay roof: Lifetime
• Concrete roof: Lifetime
• Copper roof: Lifetime

Roof inspectors are trained to look for signs of a failing roofing system that could lead to damage — especially water and structural damage. Your home's roofing materials may look great from the ground, but it's difficult to see potential damage unless you take a closer look. A roof inspector can do just that.

During an inspection, the professional will typically look for issues that may have occurred during installation and manufacturing. They’ll also keep an eye out for damage caused by normal wear and tear, as well as extreme weather events. They might also access your attic to see if there are signs of a leak in your roof.

Here’s a short list of common things a contractor will look out for during a roof inspection: 

• Damage caused by hail, wind, snow and rain
• Missing, broken, buckling, curling or cracked shingles 
• Roof decay, rot, moss, mildew and mold
• Rust around the flashing
• Damaged chimneys and vents
• Holes, gaps and punctures that could cause a roof leak
• Water stains and ventilation issues

Hiring a roofing inspector prevents you from having to do the dangerous work of climbing onto your roof. Plus, inspectors know how to assess potential damage and determine the best way to repair your roof and prevent the need for more expensive repairs in the future.

The national average for roof cleaning costs ranges between $270 and $350. Factors that can affect the cost to clean your roof are the height of your house, the size and pitch (steepness) of your roof, and the complexity of your roof’s design and accessibility. Geographic location also plays a role in roof cleaning costs as regional labor rates and area costs to do business will vary. There are several ways to clean a roof. The most common is pressure washing. Industrial pressure washers can spray over 3,000 pounds per square inch (psi) of water — which is much too powerful for roof cleaning, and may tear off shingles and damage your roof. Confirm that the roof-cleaning pro you choose will only use a low-pressure sprayer to protect your roof investment. For large algae or moss growths, pros often recommend a combination of low-pressure washing with a bleach-based chemical solution. This is referred to soft washing and should handily remove any growths taking over your roof.

Experts typically recommend that you have your roof professionally inspected at least once a year. But you also may want a licensed professional to inspect your roof during these circumstances: 

• You're buying or selling a home
• You're filing an insurance claim
• Before or after a contractor does major work on your roof
