10+ Years Protecting Homes From Roof to Ground
Most exterior companies fix one piece of the puzzle. We manage the entire path water takes across your property, so a new roof, properly sized gutters, and correct grading all work together instead of against each other. When those systems are installed by separate contractors, the gaps between them are where leaks, overflow, and standing water start. That roof-to-ground approach is what sets Rain Drainz apart in Wilmington, Newark, Middletown, and across the state. One team, one plan, one point of accountability for the place you've invested in most.

Roofing, Drainage & Exterior Services We Provide
Rain Drainz delivers complete roofing and exterior water management under one roof. From shingle and flat roofs to seamless gutters, exterior drainage, and siding, every service is built to move water away from your home and keep it there. We provide each of these services across all of Delaware and parts of PA and NJ, and every service below links to its own dedicated page where you can explore options, materials, and pricing guidance in detail.
Roofing & Roof Replacement
Your roof is the first line of water defense, and ours are built to last. We install and repair asphalt shingle and flat roofs, handle storm and wind damage, and complete full roof replacements as GAF-certified (GAF ID:1151330) installers. Whether you need a single repair after a windstorm or a brand-new system at the end of your roof's lifespan, our roof repair and replacement crews protect what matters most and back their work with manufacturer-grade materials.

Exterior Drainage & Water Management
This is our signature work and the reason Rain Drainz exists. We design and install exterior French drains, downspout and yard drainage, catch basins, buried downspouts, and regrading to pull standing water away from your foundation and landscaping. Every exterior solution is engineered to manage stormwater across your property so puddles, soggy lawns, and erosion become a thing of the past.

Gutters & Gutter Guards
Gutters carry roof water safely away before it can damage your siding, foundation, or yard. We install seamless 5″ and 6″ K-style aluminum gutters, copper, and half-round profiles, plus gutter guards that reduce clogs and cut down on maintenance. Correctly sized and pitched gutters are the critical link between your roof and your ground drainage, and we make sure that handoff is seamless on every home.

Siding, Fascia & Soffit
Siding keeps water from getting behind your home's exterior, and trim does the quiet work of sealing the edges. We install and repair vinyl and fiber cement siding from trusted manufacturers like CertainTeed and James Hardie, along with fascia and soffit that protect the roofline. The result is a tighter, drier, better-protected exterior that stands up to Delaware's wind-driven rain and seasonal storms.

Commercial Roofing & Drainage
Businesses across Delaware trust us for flat and low-slope roofing systems including EPDM and TPO, plus commercial gutters and drainage. We understand that downtime costs money, so our commercial crews work efficiently and communicate clearly to keep your building protected and
your operations running without disruption.

As a family-owned roofing company, we believe roofing and exterior water management belong together. Water doesn't stop at the roofline, and neither do we. Combining these services under one team means fewer contractors to coordinate, fewer finger-pointing problems, and a property that's protected from top to bottom.

Homeowners across Delaware choose Rain Drainz for one simple reason: we own the whole water path, roof to ground, and we stand behind every foot of it. Our reviews reflect that single point of accountability

Our Story: Exterior Water Management, Roof to Ground
Rain Drainz LLC is a family-owned company that has served Delaware since 2021. We started with a simple frustration: too many homeowners hired a roofer, then a gutter company, then a drainage contractor, and nobody owned the result. We built Rain Drainz to manage the entire path water takes, from the peak of your roof to the lowest point on your property, with one accountable team.
Our experienced exterior crews are Delaware-based and manufacturer-certified, including GAF-certified (GAF ID:1151330) roofing installers. From shingle and flat roof systems to seamless gutters, exterior French drains, and fiber cement siding, every crew member is trained to think about how each component moves water and protects the next.
Our mission is straightforward: deliver honest craftsmanship, treat your property like our own, and protect Delaware homes and businesses from water damage for the long haul. As a family-owned business, our name is on every project, and that's exactly how we like it. When you work with Rain Drainz, you get exterior water management done right, roof to ground.
