You know how they say when it rains, it pours? Well... El Nino Rains plus our 30+ Year Old House equals ROOF LEAK. We needed a Roofer. We got three referrals here on Thumbtack. Of those three referrals, it was obvious that Erik Havens and his Advanced RoofLeak Solutions business was the roofer we should go with. Doing our own research on the referrals, we found that Erik's business Advanced RoofLeak Solutions Inc. is definitely a licensed contractor whose contractor's license is, yes, actually for roofing. The state contractors database confirms this. Also, we noted that Erik's roofing business is an "Inc." meaning his business is incorporated as a corporation. We liked that because to us that meant Erik most possibly had a smart stable business. The state corporate database confirmed his business' active corporate status. As for Erik himself, don't let his youthful looks make you wonder about his experience. This 30 year old guy knows his stuff. Roofing runs in his family. Erik has been working in roofing since high school. My impression is that Erik knows how to run a quality roofing business. He is very respectful and honest when dealing with his customers. And he takes pride in his work and is thankful for his customers hiring him to do the work. We never met Erik before. But if you talk to him for a while, then you may see the same forthright excellence that we see in Erik. So, what did Erik do for us? We had a leak in the roof. This was for the roof on top of the garage for our 30+ year old house which has a red tile roof. Erik went up onto the roof with his ladder and immediately pointed out a row of tiles that were sliding down opening up an exposed area where the rain came in. That exposed area then affected an 8-ft by 8-ft area. That effect was obvious to us from inside the garage looking up at the underside of the roof where we can see a big wet stained area. Erik's work included disassembling the tiles for that section on top of the roof, putting in new underlayment material, applying roof mastic sealant, and then reassembling the red tiles back in properly aligned rows. (And there were lots of hammer pounding and other loud noise while he was working up there on the roof.) And afterwards, while he was still up there, Erik additionally checked the rest of the roof, he resealed any vent pipes (and whatever else) that needed new sealant, also checked the stability of the sun roof up there, and looked for any other potential problem tiles that could possibly be sliding out of place. There were a few other tiles beginning to slide down a bit. Sliding tiles seem to be a typical potential problem for old tile roofs. Erik secured those few other tiles pushing them back into place. Erik said the underlayment for those few other tiles was still fine. One other thing that Erik did was to clean out the gutters and make sure they were secure. Yes, imagine that: a 30+ year old house with gutters that have never been cleaned out until now. One of the gutters on the second story roof was full of leaves. Erik cleaned that out. So, Erik did a really complete job and more! My impression is that Erik is a busy roofer who is in demand. In my conversations with Erik while he was up on the roof, with myself watching him from down below, Erik mentioned how the El Nino Rains and Winds have been bringing him so much business going his way. (My guess is that this was even before El Nino as people wanted to secure their roofs in time for when El Nino arrives.) Yeah, Erik is apparently very very busy. Meanwhile, our neighbor was also looking up watching Erik and was apparently interested in also hiring Erik to work on his roof, and ended up having their own conversation as to when Erik would look at the neighbor's roof. So, Erik is apparently a busy guy, who does quality work, and is in demand. He works on roofs all over San Diego County. He goes wherever the work is located. If you are considering whether to hire Erik, we would strongly say that based on our experience to give him a call or to send him a message here via Thumbtack. Also, definitely give him your phone number and your address so he can figure out when to schedule a visit to actually look at your roof in order to give you a proposed written estimate. Erik's proposal for fixing OUR roof was a good reasonable fair price. My suggestion is to NOT go cheap in repairing your roof. The two other referrals that we got from Thumbtack would have been cheaper and would have undercut Erik's proposal where one thumbtack referral was from an unlicensed roofer who was not in the state contractors database and the other thumbtack referral was from a solar guy whose contractor's license was for electrical. For our roof, we were willing to pay a little more for a quality roof repair by a licensed experienced roofer (whose contractor's license was actually for roofing) and we expected the roofer to stand behind his work. And we indeed got a qualified licensed experienced roofer in Erik Havens and his Advanced RoofLeak Solutions business. Thanks Erik.

Very happy with the roof cleaning which removed the black mildew and left my roof looking new again. Kevin was very pleasant to work with. The price seemed reasonable. I will be getting Windows cleaned by Kevin next.

We hired Tom to clean a section of tile roof over our porch which receives very little sun, and had an unsightly greenish growth after 12 years Tom was a pleasure to work with, from setting up our appointment to performing the work, and he did an excellent job of cleaning up after the wash process. He called before arriving, showed up on time and finished the job within the estimated time. Our landscaping below the roof was protected with tarps, and cleanup after pressure washing was done very thoroughly. Tom also pressure washed sample sections of our house walls and sidewalks to show the potential of removing mold, moss, dirt, etc. We will definitely have him back to clean up our stucco on the house and perimeter walls, and additional sections of tile roofing.

First things first, R&R Roofing Contractors Inc. had the lowest estimate out of eight companies to remove and replace our existing roof. They started and completed the work in under three days during record breaking heat of 100 plus degrees in Escondido. Robert and his crew were professional, courteous, and very friendly. They not only did everything called for in our contract, they went above and beyond while repairing the damaged plywood and fascia boards that were found. Robert kept us advised of how the work was going and what to expect each day. They cleaned up around our house and removed any nails or debris at the end of each day. The quality of their work is exceptional and our new roof looks great! We highly recommend R&R Roofing Contractors to anyone.

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.

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.

What chemicals are used to clean roofs?

Roof cleaning is done to remove moss, lichen, algae, and buildup of other grime and dirt. There are several methods for roof cleaning, which can include a chemical soft wash, pressure washing, low-pressure washing and hand washing. When a chemical soft wash is used, a bleach mixture is sprayed onto the roof. The bleach-based solution is absorbed by the algae or moss, which dies from exposure to the chemical. The roof is then sprayed with a low-pressure rinse of water, which loosens the now-dead material, allowing it to slide off the roof.

For homeowners, the Asphalt Roofing Manufacturers Association recommends a mixture of 50 percent laundry-strength liquid chlorine bleach and 50 percent water. Professional roof cleaning companies will use an industrial mixture that is still safe but may be more effective in eliminating algae and moss growths. Asphalt shingle roofs are the most common type of roof, but each roofing material will have its own cleaning needs, so it’s best to consult with your roofing pro before diving in. Don’t do it yourself unless you can safely navigate your roof, the chemicals and a sprayer system. When in doubt, leave it to the pros.

How much does it cost to clean a roof?

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.
