Common Questions About Our Service Areas
Don't see your city listed?
Call us at 410-508-6141 — we regularly work in areas not listed here. Our core radius covers roughly 35 miles from our Severn, MD headquarters (1245 Thompson Ave, 21144). If you're in central Maryland and need a licensed roofer or exterior contractor, there's a good chance we can help.
How quickly can you get to my city?
Most homeowners in Anne Arundel and Howard County get a same-day or next-day inspection for active leaks. Scheduled free estimates are typically within 24–48 hours. Baltimore County projects may take an extra day depending on crew availability. We never send a subcontracted crew — you get our own team every time.
Do you handle multi-county projects?
Yes. If your property spans a county line, or if you have rental properties in different counties, we can coordinate permits and inspections across jurisdictions. Our estimators are familiar with the permit offices in Anne Arundel, Howard, and Baltimore County. We pull permits in all three counties regularly.
Are your crews local to each area?
Our crews live and work in central Maryland — most within 20 miles of Severn. We are not a national franchise with rotating crews. The same experienced team that completed your neighbor's roof is the one that shows up for yours. MHIC #05-146983 · 4.9★ across 48 Google reviews · family-owned since 2016.
