How Our Process Works

Your project begins with a detailed site evaluation, measuring roof area, identifying drainage issues, and selecting the membrane system that fits your budget and timeline. The crew prepares the surface by removing old material, repairing substrate damage, and confirming that slopes direct water toward drains and scuppers in Rapid City.

Diamond Ridge Exteriors applies insulation layers when needed, then rolls out the membrane with overlapping seams that are either heat-welded or adhered using manufacturer-specified adhesives. Flashings are cut, shaped, and secured around HVAC units, vents, and edges to create a continuous barrier.

The final inspection includes a water test to confirm zero leaks and documentation that supports warranty activation. You walk away with a roof built for long-term durability and minimal maintenance.

What's Included in This Service?

Property owners often have questions about materials, maintenance, and what separates a reliable flat roof from one that fails within years. Here are the answers you need.

What flat roofing material lasts longest?
TPO and EPDM both offer 20-plus years of service when installed correctly. Your material choice depends on exposure, foot traffic, and building use.
How do you prevent ponding water?
Proper slope adjustments, drain placement, and tapered insulation direct water off the roof. Every flat roofing Rapid City project includes drainage planning.
Can you repair an existing flat roof without full replacement?
Yes. Spot repairs, seam re-welding, and flashing replacements extend roof life when the substrate remains sound.
How long does installation take?
Most commercial flat roofs finish within three to seven days, depending on size and complexity. Residential additions often complete faster.
Do you service buildings outside the city center?
Absolutely. Work is available throughout Rapid City and the surrounding area, including industrial zones and rural properties.

A properly installed flat roof stops leaks, reduces energy costs, and protects your investment for decades. Whether you manage a commercial building along a busy corridor or own a home with a low-slope addition, you deserve a system that performs. Reach out now to arrange your property assessment.
