Homeowners across Derwood call Big Toms Roofing because we do what we say — show up on time, explain what we find in plain language, and stand behind every Roof Replacement job with a written warranty.
We built Big Toms Roofing to fix a problem every homeowner in Derwood has run into: contractors who don't return calls, no-show for appointments, or pad the invoice once the tarp's already on the roof. Our Roof Replacement crews are local, licensed, and accountable — every estimate is in writing before a single shingle gets pulled.
From a single missing shingle to a full tear-off, our Derwood crews handle every stage of roofing work with the same attention to detail — licensed, permitted, and cleaned up when we leave.
A leak that starts as a small stain can rot decking and framing within weeks. Our emergency response teams treat every active-leak call in Derwood as urgent — temporary stabilization first, permanent fix scheduled right behind it.
When patching stops making financial sense, a full tear-off and reroof resets the clock on your home. We strip old material down to the deck, replace any rotten sheathing, install proper underlayment and ice-and-water protection, and finish with a manufacturer-certified shingle or metal system backed by a real warranty.
Downtime costs money, so commercial Roof Replacement jobs get scheduled around your operating hours whenever possible, with clear communication to property managers and tenants throughout the project.
A lot of roof failures are preventable with a twice-a-year inspection catching lifted flashing or worn pipe boots before they turn into interior water damage. Our Derwood inspection service checks the field, flashing, penetrations, gutters, and attic ventilation, then hands you a written report with photos.
Ice damming is a real problem in Derwood, MD winters when it happens. We install proper ice-and-water shield and improve attic insulation and ventilation to stop the freeze-thaw cycle that damages eaves.
Every one of these commitments exists because a Derwood homeowner asked for it, complained about a competitor's lack of it, or we learned it the hard way.
Every estimate is itemized and handed to you before we touch the roof — no verbal quotes that change once the ladder comes down.
Because our trucks stay staged around Derwood, we're rarely more than an hour from your address for emergency calls.
Our installers hold current manufacturer certifications, which means your warranty stays intact and the work meets code.
Every completed job comes with a written workmanship warranty separate from the manufacturer's material warranty.

"The estimate they gave us matched the final invoice exactly, which after two other quotes from companies that kept adding line items, was a relief. Crew was professional and cleaned up better than I expected."
