There are a few potential dangers to using a roofer from out of town, including:

1. Lack of local knowledge: A roofer from out of town may not be familiar with the specific building codes, zoning laws, and weather conditions in your area. This could lead to compliance issues or a roof that is not properly designed to withstand local weather.

2. Difficulty in obtaining permits: Out-of-town roofers may not have established relationships with local building departments and may have difficulty obtaining the necessary permits to perform the work.

3. Lack of accountability: If an out-of-town roofer does poor work or fails to complete the job, it may be difficult to hold them accountable. They may not have a physical presence in your area and may be difficult to contact after the job is done.

4. Warranty concerns: An out-of-town roofer may not be able to provide a warranty that is valid in your area, or may not be around to honor the warranty if there is a problem.

5. Insurance Issues: If the roofer is not licensed in your area, they may not have the necessary insurance coverage to protect you in case of accidents or damages.

6. Quality of work and materials: You might not be able to check the company’s previous work, and there will be less room for negotiation if you find defects in the work.

7. Unforeseen costs: An out-of-town roofer may not be aware of all the costs associated with working in your area, such as travel expenses, which could be passed on to you in the form of higher prices.

It’s always best to use a local contractor, who is familiar with the local building codes, weather conditions and has a physical presence in the area.
