He listened, had me text him a quick picture, then offered a great rate for what I was requesting and said he could come by the same day at 3:30. He showed up exactly on time and even texted to let me know he was 15 mins out, nice touch. He set up, did an excellent job, actually a bit above and beyond what he committed to, and did excellent work. Also, just a good dude. Won't hesitate to call him again. "

"I am writing to formally report a case of fraud involving a contractor I engaged through Angi, who processed payment via Square under the name Irving & Kkelen. We initially agreed on a crown molding installation project valued at approximately $600. During the discussion, the contractor demanded an upfront payment of $400 for materials, which I paid through Square (link to transaction: https://squareup.com/u/y0iPCBB6). He then asked for additional $200 for labor, which I denied, but subsequently agree to pay additional 100 on top of $600 upon job finish. However, the contractor failed to show up to complete the work and merely left some materials at my residence without providing any purchase receipts or verification. When I attempted to follow up, he became hostile and verbally abusive, using racially charged language such as, Do you think $600 is enough to make me work? and Do you think Mexicans always work cheap? and "Don't messed up with Mexican". This behavior is not only unprofessional but also potentially unlawful. Under California Civil Code § 1572, fraud includes the suggestion, as a fact, of that which is not true, by one who does not believe it to be true and a promise made without any intention of performing it. Additionally, collecting payment for services not rendered may constitute a violation of California Business and Professions Code § 7159.5, which prohibits home improvement contractors from demanding excessive or deceptive upfront payments and requires proper documentation, including written contracts and itemized receipts. To date, the service has not been rendered, and multiple attempts to resolve this with the contractor have failed. I believe this transaction was executed in bad faith and constitutes fraudulent misrepresentation. I am therefore requesting that Angi urgently investigate this matter and initiate a refund for the amount paid. I am prepared to provide supporting documentation, including correspondence, photos, and recordings, if needed for your review. Thank you for your immediate attention to this issue. Please let me know the next steps and any additional information required."

FAQs for roof cleaning service projects in Castro Valley, CA
Yes, roof cleaning is a necessary task. A clean roof keeps moisture from seeping under shingles, cuts down on decay, and can add 10 to 20 years to its life. Routine cleanings also sharpen curb appeal and let a pro spot loose flashing or soft spots before they turn into repairs that cost thousands of dollars. In short, a modest cleaning bill now protects you from a far larger roofing invoice later on.
If your roof is dirty, mossy, or covered in algae, start by washing your roof. In many cases, this is all that’s needed, but it’s also a helpful first step to uncovering any other issues. If your roof cleaning pro discovers missing, loose, or damaged shingles while washing, or if you notice that the flashing leaks, it may be time for repairs.
Plan on a cleaning every two to five years, but let climate guide your schedule. If you live in a damp, moss‑prone region, aim for the shorter end of that range; arid areas can wait longer. Sticking to a regular cadence keeps algae from eating into shingles and helps you avoid bigger repair bills down the road.
Schedule the job in late spring or early summer when daylight is long, temperatures are steady, and shingles are dry. A fall touchup after the leaves drop also helps you head into winter with a clear surface. Cold, icy conditions make cleaning risky and can trap water under shingles, so steer clear of freezing forecasts.
