Our Services

What Big Toms Roofing Handles in Derwood

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 โ€” licensed, permitted, and cleaned up when we leave.

01

Storm Damage & Emergency Tarping

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 โ€” temporary stabilization first, permanent fix scheduled right behind it.

02

Complete Tear-Off & Reroof

Whether your roof is past its expected lifespan or storm damage made repair impractical, our replacement crews handle permitting, disposal, and installation start to finish, with a written timeline you can plan around.

03

Commercial Roofing Services

Commercial roofs fail differently than residential ones โ€” ponding water, seam separation, and membrane wear don't always show up until there's a leak on the sales floor below. Our Derwood commercial division services TPO, EPDM, modified bitumen, and built-up roofing systems on retail, industrial, and multi-family properties.

04

Preventive Roof Maintenance in Derwood

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.

05

Flashing, Gutters & Attic Ventilation

Poor attic ventilation cooks shingles from underneath and can void manufacturer warranties. Our Derwood crews balance intake and exhaust ventilation to extend the life of your Flat Roof Repair system and lower attic temperatures in summer.

Why Choose Us

What Sets Big Toms Roofing Apart in Derwood

We're not trying to be the biggest Flat Roof Repair company in Derwood, MD โ€” we're trying to be the one you'd actually recommend to your neighbor.

01

Upfront, Written Pricing

Every estimate is itemized and handed to you before we touch the roof โ€” no verbal quotes that change once the ladder comes down.

02

Rapid Local Response Times

Because our trucks stay staged around Derwood, we're rarely more than an hour from your address for emergency calls.

03

Certified Installation Crews

Certification isn't a marketing badge here โ€” it's required training that affects how your warranty is honored.

04

Workmanship Warranty

Every completed job comes with a written workmanship warranty separate from the manufacturer's material warranty.

05

Insurance Claim Support

We document damage the way adjusters expect to see it, which shortens the back-and-forth on storm claims.

06

Clean Jobsites, Every Day

Magnetic nail sweeps and tarp-protected landscaping are standard on every job, not an upsell.

"We had a leak show up during a storm at night and I honestly didn't expect anyone to answer the phone. Big Toms Roofing had a crew tarping our roof within a couple hours and came back two days later to do the real repair. Can't recommend them enough."

Homeowner, Derwood

Frequently Asked Questions

Flat Roof Repair FAQ for Derwood Homeowners

What's your response time for Derwood emergencies?+
For active leaks or storm damage, we prioritize Derwood calls and typically have a crew on-site within a few hours. Standard inspections and estimates are usually scheduled within 24 to 48 hours, often sooner depending on our current route through Derwood.
How does your pricing work?+
Yes. Every job starts with a free inspection and a written, itemized estimate. We don't start work off a verbal quote, and the price you approve is the price on the final invoice unless you request additional work.
Are you licensed and insured to work in Derwood, MD?+
We hold an active MD contractor license and full insurance coverage, and we'll provide proof of both on request โ€” most Derwood customers ask, and we expect that.
