They Show Up Uninvited After a Storm
Storm chasers knock on doors in neighborhoods that just got hit by hail or wind. They offer to inspect your roof and siding for free and then pressure you to sign a contract on the spot. Legitimate contractors do not cold-call door to door after storms. They have enough work from their existing reputation.
They Want a Large Deposit Upfront
Any contractor asking for more than one-third upfront is a red flag. Contractors who demand half or full payment before starting are either in financial trouble or planning to disappear. A legitimate contractor can afford to start with a reasonable deposit because they have cash flow from ongoing projects.
They Cannot Provide a Written Contract
Handshake deals and verbal agreements offer you zero protection. A professional contractor provides a detailed written contract that includes scope of work, materials, timeline, payment schedule, warranty terms, and change order process. If they resist putting it in writing, there is a reason.
Their Quote Is Drastically Lower Than Everyone Else
If one quote is dramatically below the others, something is missing. They might be cutting corners on materials, skipping the weather barrier, using unlicensed labor, or not pulling permits. The lowest quote is rarely the best value.
They Pressure You to Decide Today
Good contractors give you time to think, compare quotes, and make a decision. If someone tells you the offer is only good today, or that they can squeeze you in only if you sign right now, they are using pressure tactics. Walk away.
They Have No Online Presence
In 2026, a legitimate siding contractor should have a website, reviews on Google or similar platforms, and a verifiable business address. If you cannot find any trace of them online, they may be operating under a different name due to a bad reputation.
