Our Roofing Services in Wilmington, DE
We handle every type of roofing service in Wilmington and New Castle County: replacement, repair, flat-roof systems, inspections, commercial work, and storm damage. Explore each service below to see how we handle repairs, replacements, and storm damage step by step.
Roof Replacement
When repairs no longer make sense, a full replacement protects your property for decades. We install asphalt shingle, flat, and commercial systems with complete tear-off, GAF-certified materials, and workmanship warranties. Learn more about Roof Replacement and the lifespan you can expect.
Roof Repair
A small leak today becomes interior damage tomorrow. Our crews respond fast to leaks, storm and wind damage, and missing shingles, stopping the leak at its source rather than just covering symptoms. See how we handle Roof Repair for lasting fixes.
Flat Roof Coatings
For flat roofs on row homes and flat commercial buildings, silicone and flat-roof coatings extend service life and seal against ponding water. Flat roof coatings are designed specifically for low-slope and flat systems and are not used on pitched shingle roofs. Explore Flat Roof Coatings to restore your existing membrane.

Catching leaks, storm damage, and ordinary wear early saves thousands. Our detailed inspections document the true condition of your roof across New Castle County and give you a clear, no-pressure plan. Schedule a Roof Inspection before small problems grow.

Our Roofing Service Area — Delaware, Plus Nearby PA & NJ
Rain Drainz serves Wilmington and all of New Castle County, including Newark, Middletown, Bear, New Castle, Hockessin, Greenville, Pike Creek, Claymont, and Elsmere. Explore our service area to confirm we cover your neighborhood.
From our base at 11 Lewis Cir, Wilmington, DE 19804, we reach larger replacement and commercial jobs across the wider region within roughly a one-hour radius, while repair calls closer to Wilmington often see service in around 45 minutes. That local footprint means faster response when a leak or storm can't wait.
Because we live and work in the same communities we serve, we know how Delaware coastal storms, freeze-thaw cycles, and heavy seasonal rain can stress a roof over time. We build every system to handle local conditions and to feed water cleanly into your gutters and drainage, the way a complete exterior should work.
Roofing That Protects the Top of Your Water System
Your roof is where exterior water management begins. We approach every project with a roof to ground mindset: the roof sheds rainwater to the Gutters & Gutter Guards at the roofline, and from there Exterior Drainage & Water Management carries it safely away from your foundation. When all three layers work together, your property stays dry from the shingle down to the soil.
That system only performs if the roof is installed right. Our crews are GAF certified, experienced, and meticulous, using premium materials and proven methods on asphalt, flat, EPDM, and commercial systems alike. We don't cut corners on flashing, ventilation, or underlayment. These are the details that decide whether a roof lasts ten years or thirty.
As a family-owned company operating in Wilmington since 2021, we answer to our neighbors, not a distant corporate office. That local accountability is why we stand behind our work with both a workmanship warranty on our installation and the manufacturer warranty on GAF materials. When you hire Rain Drainz, you get a partner invested in the long-term performance of your roof and the whole water system beneath it.
Delaware Roofing FAQs
How do I know if I need a roof repair or a full replacement?
Repair makes sense for isolated leaks, a few missing shingles, or localized storm damage on a roof with years of life left. Replacement is the smarter investment when your roof is sagging, has recurring leaks or widespread granule loss, and is over 20 years old. We give you an honest assessment so you can compare your options on our Roof Repair and Roof Replacement pages.
How much does a new roof cost in Delaware?
Most Delaware roof replacements range from roughly $10,000 to $15,000, depending on roof size, pitch, material, and the condition of the sub-structure. Repairs typically cost far less. The most accurate number comes from a free on-site estimate. See our Roof Replacement page for details, then call (302) 488-8377.
What roofing materials do you install?
We install asphalt shingle, flat, EPDM, metal, and commercial roofing systems. Asphalt shingles suit most pitched homes, while flat and low-slope buildings benefit from EPDM, TPO, or restorative Flat Roof Coatings. For businesses, our Commercial Roofing team matches the right system to your building and budget.
Do you repair storm and wind damage?
Yes. We provide emergency storm response plus insurance-claim assistance for wind and hail damage across New Castle County. Our crews tarp and stabilize quickly, document the damage thoroughly for your claim, and restore the roof to full performance. Start at our Storm Damage Roof Repair page or call us right away.
Are you licensed, insured, and GAF certified?
Yes. Rain Drainz is licensed and insured in Delaware (DE# 2023700737) and is a GAF-certified roofing contractor. We're a family-owned company with a 4.9 stars rating from 140+ Google reviews, which means your roof is installed to manufacturer standards and backed by both workmanship and manufacturer warranties.
