Quality Commercial Roofing Contractor Services

  • Commercial Maintenance Programs

    Alliant typically checks and cleans commercial flat roofs twice a year, in March and November. Drains and scuppers are prone to clogging and need periodic cleaning. Commercial Maintenance Programs with their regular inspections help to identify damaged roofing material and insulation.

  • Dedicated Leak Response Division

    Alliant Roofing maintains a 24-hour emergency response hotline linked to key company personnel, if your commercial roof requires immediate repairs. Call (800) 437-7201.

  • TPO Single Ply Roof Systems (Manufacturer warranted)

    TPO membrane roofing is the most prominent type of commercial flat roofing system. Often, it is white vinyl roofing, comes in rolls, and is mechanically applied, screwed down to the roofing deck. A single-ply, TPO membrane roofing system is the recommended replacement for hot tar, hot mop, built up and torch down commercial roofs.

    • Roof Cleaning and Inspection

      Roof inspections are about prevention and detection. It is important to identify damage to vulnerable TPO roofing systems. If left unrepaired, TPO roof punctures can compromise an entire roofing system, including rigid insulation.

    • Polyiso Rigid Insulation

      Polyiso rigid insulation is a low-cost, long-life product that may be installed beneath a new, flat commercial roof. Alliant Roofing assures that new polyiso insulation meets all building code requirements.

    • Sheet Metal Flashings, Copings And Gutters

      Every roof has eave edges and terminations. Alliant Roofing has an in-house metal shop to fabricate flashings and copings for TPO roof systems. Alliant is able to custom-bend flashings to meet all applications.

    • Soffit and Fascia

      Alliant Roofing Company provides aluminum and steel soffits at roof perimeters and eave edges, especially in conjunction with TPO roofing systems. Older soffits may leak or rust, eventually needing replacement.

  • PVC Membrane Roofing Systems (Manufacturer warranted)

    PVC’s installation process is similar to TPO, and PVC roofing holds up better to chemical abuse than does TPO on low slope roofs. Call us for a free, commercial roof budget estimate.

  • Metal Roof Systems

    Metal roofs are a unique alternative to TPO/PVC membrane roofing systems. Options include standing seam metal roof systems in a variety of colors and finishes.

  • Existing Roof Repair, Roof Replacement and Asbestos Abatement

    Roof repairs are cheaper than roof replacements, so proactively maintaining your roof is a wise investment. Recovering your roof is the next best option, because it leaves the existing roof in place, saving time and money. If your roof must be replaced, Alliant Roofing has the experience and expertise to do the job right. If asbestos were found, Alliant is fully certified in the Asbestos Abatement programs administered by the Spokane Regional Clean Air Agency (SRCAA), Puget Sound Clean Air Agency and the Benton Clean Air Agency.

  • Extend Metal Roof Life with Coatings and Retrofits

    Alliant Roofing uses roof coatings to extend the lives of metal roof systems. To seal leaks around grommets, Alliant applies Henry® and Karnak® aluminum roof coatings, or GAF Topcoat, a fluid-based rubber system. When sealants are not enough, retrofitting a commercial metal roof with TPO is a cost-effective alternative to replacing the entire metal roof.

  • Public Works Projects

    Alliant Roofing Company has completed public works projects for Public School Districts, the Army Corps of Engineers, the United States Air Force, Community Hospitals, Department of Transportation and Grant County International Airport (funded by the FAA).

  • Manufacturer Warranty Work

    GAF® Master Select™ Commercial Roofing ContractorAlliant Roofing Company maintains certification under premier commercial roofing manufacturers, including GAF, Versico (a Carlisle company) and Firestone Building Products.

  • Insurance Work

    Alliant Roofing Company works with local emergency response crews, typically Servpro® and ServiceMaster®, when same-day response is necessary. Alliant, building owners and insurance claims adjustors all collaborate to minimize the business impact.
