Roof Drainage Solutions

Managing Rainwater Effectively Here at C&M Construction and Roofing, we understand the importance of proper drainage for protecting your home and extending the life of your roof. While most homeowners consider gutters the primary drainage system, there are often additional solutions needed, especially for commercial structures. Our team of experts can evaluate your specific needs to design, install and maintain a complete, code-compliant drainage system.

The Risks of Poor Drainage

When water isn’t managed efficiently, it can create serious issues over time:

Heavy rainfall that isn’t redirected away from your home’s foundation can seep in and cause cracks or bowing in basement walls. Standing water near the structure also invites wood rot around windows, doors, and siding.

Inadequate drainage leads to premature failure of asphalt shingles as water works its way under the shingles, speeding up the degradation process. Other roof materials like metal and tile also suffer damage from repeated moisture exposure.

Commercial flat roofs that pond water are at high risk of leaks developing at seams as the membrane deteriorates more quickly when saturated. This can damage interiors and costly repairs may be required.

Our Drainage Solutions

We offer the following options to establish fully-protected, long-lasting drainage:

Gutters & Downspouts: Hung or half-round seamless gutters and round/square downspouts in aluminum or steel. We ensure proper sloping, splashes, and extensions to redirect water at least 5 feet from foundations.

Scuppers: Installed through exterior commercial walls near roof edges, these openings allow water to flow through safely using interior downpipes. Screens prevent insect/debris entry.

Through-Wall Flashing: Installed behind siding or stucco, this flashing directs the water flowing through scuppers to the exterior while protecting the waterproof building wrap.

Parapet Walls: On flat commercial roofs, these short retaining walls prevent water from spilling over the edge and also help block wind and rain from entering the roof area.

Control Drains: Strategically placed throughout large commercial roofs, these drain inlets vacuum up ponding areas through underground piping to storm drains.

French Drains: Trenches filled with gravel and perforated pipes underground help divert exterior surface water away from structures to approved drainage areas.

Our Evaluation and Installation Process

 

  1. Site Survey: We note existing systems, measure collection and identify any problem drainage locations.

 

  1. Design Planning: Optimized CAD schematics illustrate a fully-integrated, code-compliant solution considering all water collection points and directional flow.

 

  1. Material Sourcing: High-quality, durable materials are acquired like smooth-wall piping, fittings, specialty drains, gravel, and non-woven fabric borders.

 

  1. Installation: Our crews precisely cut, assemble and secure all components such as hangers, strapping, fastening dams, and protective screening per design specs.

 

  1. Final Inspections: The installed system is thoroughly reviewed for flow efficiency and weakest point identification before receiving final approval.

 

  1. Post-Job Service: Any necessary repairs or upgrades are provided following the warranty period and we can offer maintenance contracts.
