Single-Ply Roofing Systems

Single-ply roofing systems typically appear on commercial flat roofs. Roofing materials include thermoplastic polyolefin (TPO), polyvinyl chloride (PVC), ethylene propylene diene monomer (EPDM) and ketone ethylene ester (KEE).

TPO Single Ply Roofing Systems (Manufacturer warranted)

TPO membrane roofing is the most prominent type of commercial flat roofing system. A 60 mil, single-ply, TPO membrane roofing system is the recommended replacement for hot tar, hot mop, built-up roofing (BUR) and torch down commercial roofs. Learn more about TPO in our Buyer’s Guide for building owners, managers, public works administrators and architects. Recent GAF® and Firestone Building Products TPO roofing projects include:

PVC Membrane Roofing Systems

PVC’s installation process is similar to TPO, although, PVC roofing holds up better to chemical abuse than does TPO on low-slope roofs. Recent Versico Roofing Systems PVC roofing projects include:

EPDM Membrane Roofing Systems (Rubber Roofing)

The popularity of EPDM for new construction has declined with the rise of TPO and PVC roofs. We still encounter it on public works and rubber roof recover projects.

Commercial Roof Cleaning, Inspection and 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.

Roof inspections are about prevention and detection. It is important to identify damage to vulnerable membrane roofing systems. TPO, PVC, EPDM and KEE roof punctures can compromise an entire roofing system, including rigid insulation. Alliant Roofing offers Roof Asset management as a premium roof inspection and lifetime management service.

Dedicated Leak Response Division

Alliant Roofing maintains a 24-hour emergency response hotline linked to key company personnel, if your roof requires immediate repairs.

Existing Roof Repair, Recover, Replacement (Re Roof), Demolition and Asbestos Abatement

Roof repairs are cheaper than roof replacements, so proactive maintenance is a wise strategy. Recovering your roof is the next best option, because it leaves the existing roof in place, saving time and money. 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.

Manufacturer Warranty Work

Alliant Roofing Company maintains commercial roofing contractor certifications with premier roofing manufacturers, including GAF, Versico Roofing Systems, Firestone Building Products, FiberTite and Metal Sales.

Insurance Work

Alliant Roofing Company works with local emergency response crews, typically Servpro® and ServiceMaster®, when same-day response is necessary. Insurance claims adjustors join with ARC and business owners in this process.
