Flat Roof Installation

Hail-rated flat roof installation built for Denver's four-season climate and strict drainage requirements.

Flat Roof Installation in Denver

Denver's frequent hail and rapid temperature swings demand membranes that stay flexible below freezing and resist impact damage. We install 60-mil TPO or reinforced EPDM over ISO insulation, mechanically attached or adhered, with heat-welded seams that hold up on buildings near Red Rocks Park and the Denver Art Museum.

Flat roofs on older Capitol Hill and Highland homes often have hidden slope issues and aging scuppers. We tear off to the deck, add tapered insulation where needed, and install new edge metal and cricket details so water never ponds against parapets or around Union Station-area commercial conversions.

Denver permitting requires positive drainage, wind uplift ratings, and proper flashing heights. Our team pulls permits under license 1241222 and coordinates inspections so the finished roof passes first time. We never skip the final flood test before we leave the job.

Access on Shys Hill Rd properties can be tight; we stage materials efficiently and protect landscaping during the entire process.

How it works

  1. 1

    Site evaluation

    Measure the roof, check existing slope and drains, note hail damage, and review Denver code requirements for the neighborhood.

  2. 2

    Material selection

    Choose TPO or EPDM thickness and insulation R-value based on hail exposure and building use, then confirm color and warranty options with the owner.

  3. 3

    Deck prep and insulation

    Remove old roofing, repair or replace damaged decking, install tapered ISO to achieve positive drainage, and fasten base layer.

  4. 4

    Membrane install and detailing

    Roll out membrane, heat-weld all seams, flash penetrations and walls, install edge metal, and perform flood test before final sign-off.

  5. 5

    Cleanup and documentation

    Remove all debris, provide owner with care instructions, permit paperwork, and our contact for future maintenance.

Pricing

Cost depends on square footage, membrane type, insulation thickness, and roof access. We provide free written estimates during Mon–Fri 8am–6pm or Sat 9am–2pm hours from our Shys Hill Rd location.

+ How do you prevent ponding water on flat roofs in Denver?
We install tapered insulation to create positive slope to drains or scuppers and add crickets behind equipment so water moves off the roof quickly.
+ Which membrane holds up best to Denver hail?
60-mil reinforced TPO or EPDM with impact modifiers performs best; we match thickness and attachment method to the hail exposure of the specific neighborhood.
+ Do flat roof installations require permits in Denver?
Yes. We handle all permitting and inspections under license 1241222 so the work meets current Denver building code for wind and drainage.
+ Can you install a flat roof over an existing sloped roof?
Only after we confirm structural capacity and add proper crickets; most jobs require full tear-off for warranty and code compliance.
