What’s Included in a Full Roof Replacement?
A roof replacement is more than installing new shingles. It’s a complete roofing system designed to protect your home from Wilmington’s changing weather, including heavy rain, coastal humidity, strong wind storms, and freezing winter conditions that can contribute to ice dams.
Whether you own a historic home in Wilmington or a newer house elsewhere in New Castle County, we replace every roof using proven installation methods and high-quality materials built for Delaware's climate.
Roof Systems We Replace
We install asphalt shingle roofs (the most popular choice for Delaware homes), flat and low-slope systems including EPDM and TPO, metal roofing, and commercial low-slope roofs. Not sure which fits your home? See our Asphalt Shingle Roofing page or, for business properties, Commercial Roofing in Wilmington, DE.
Tear-Off & Deck Repair
We perform a full tear-off to the deck rather than layering new shingles over old ones. With the deck exposed, our crew inspects the wood sheathing for rot, soft spots, and water damage, then repairs or replaces any compromised decking before installation begins. A solid deck is the foundation of a long-lasting roof.
System Components
A new roof is more than shingles. Every replacement includes synthetic underlayment, ice-and-water shield in the valleys and along eaves, drip edge, step and counter flashing, starter strip, and ridge vents. These components work together to seal vulnerable points and channel water off the roof.
Materials
We install GAF shingles and matching GAF components, giving you access to a wide range of color and product lines, from dependable architectural shingles to premium designer profiles. As a GAF-certified roofer, we install to the standards required for enhanced manufacturer warranties.
Ventilation
Proper attic ventilation regulates temperature and moisture, which extends roof life and helps prevent premature shingle aging and ice dams. We balance intake and exhaust ventilation as part of every new roof installation.
Cleanup & Disposal
When the roof is finished, we run a magnetic nail sweep across your property and haul off all old materials and debris. You're left with a clean yard and a roof that's ready for decades of weather.
Financing
A roof is a significant investment. We offer financing options that make larger asphalt and flat roof replacement projects manageable, so you can protect your home without delay.

Our roof replacement process is a clear five-step path from inspection to final walkthrough, designed to keep you informed and your property protected at every stage.

Roof Replacement Across Wilmington & New Castle County
Whether you're replacing the roof on a historic Wilmington row home, a suburban house in Newark or Bear, or a newer home in Middletown, Rain Drainz delivers the same attention to detail, honest communication, and quality workmanship on every project.
As a local Wilmington Roofing Company, we proudly replace roofs throughout Wilmington, Newark, Bear, Middletown, New Castle, Hockessin, Pike Creek, Greenville, Elsmere, Claymont, and surrounding New Castle County communities.
Because we're a local Delaware contractor, we understand the roofing challenges homeowners face across the region. Coastal humidity can shorten the life of aging shingles, strong wind storms can loosen or remove roofing materials, and heavy seasonal rain can expose hidden leaks. Many older homes throughout Wilmington also require careful roof deck inspections before new roofing materials are installed to ensure a long-lasting result.
No matter where you live in our service area, you'll receive a thorough roof inspection, straightforward recommendations, premium roofing materials, and a complete cleanup after installation. Our goal is to install a roof that's built to protect your home through Delaware's changing seasons, not just pass inspection on installation day.

Roof Replacement FAQs
How much does a new roof cost in Wilmington, DE?
A new roof in Wilmington, DE typically costs between $10,000 and $15,000 for a standard-sized home with architectural asphalt shingles. Total cost depends on roof size, pitch, material, and the amount of deck repair needed. We also offer financing.
Do I need a roof replacement or just a repair?
You likely need a replacement if your roof is 20+ years old, has widespread leaks, sagging, storm damage, or heavy granule loss. Isolated damage often calls for a fix instead (explore Roof Repair in Wilmington, DE). During your free inspection, we'll tell you honestly which option makes financial sense.
What roof types do you replace?
We replace asphalt shingle, flat (EPDM and TPO), metal, and commercial low-slope roofs. Asphalt is the most common choice for Delaware homes (learn more on our Asphalt Shingle Roofing page). For business properties, see Commercial Roofing in Wilmington, DE.
How long does a roof replacement take?
Most residential roof replacements take one to three days, depending on roof size, complexity, weather, and the extent of any deck repair. Larger or commercial projects may take longer. We give you a clear timeline in your written quote and keep the job on schedule.
Do you offer financing and warranties?
Yes. We offer financing for larger replacements, and every new roof is backed by both a GAF manufacturer warranty and the Rain Drainz workmanship warranty. As a GAF-certified roofer, we install to the standards required to qualify your roof for enhanced manufacturer coverage.
