 Northampton, PA

What was the old roof?

The old roof was smooth modified-bitumen that had been coated heavily multiple times but still leaked badly.  The low-slope roof has low parapets and most of the substrate was wet requiring a tear-off.  The deck had an average fastener withdraw pull-test strength of 450 LB.


What is the new roof?

The new roof is Duro-Last 50 mil reinforced white PVC over polyiso insulation.  The roofing membrane is mechanically attached directly to the roof deck 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 Basic Warranty covers ponding water and has no required maintenance reporting.  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.
