What was the old roof?

The old commercial roofing was ballasted EPDM over a steel deck that had been leaking badly for some time causing ongoing tenant complaints. The roof is low-slope with parapets on the front. The roof substrate was dry. The deck had an average fastener withdraw pull-test strength of only 400 LB. A portion of the roof had been replaced due to fire damage.


What is the new roof?

The new roof is Duro-Last 40 mil pre-fabricated reinforced white PVC that eliminates up to 85% of on-site welding. The roofing membrane is mechanically attached through the old roofing material directly to the roof deck saving the expense of tear-off & new insulation and ensuring the most reliable resistance to high-winds. Seams are welded with the safety of hot air and are permanent unlike taped seams. The Duro-Last Supreme Warranty covers any consequential damage from leaks and has no required maintenance. Duro-Last is Energy Star® rated and highly-resistant to the expansion & contraction that degrade black roofs. No TPO is used to make Duro-Last, only PVC that has been proven over the last 40 yrs.
