                      What is the reason you should have 'Core Cut' ?                





1. First and foremost to see what is under the roof. ( A roof can have other roofs below ).


2. It is important to see what type of roof deck is under the roof. - The most common roof deck is steel. If it is


     not a steel deck then it is either wood, gypsum, " Tectum " or concrete . If you have a roofing contractor come


     and take measurements and does not take a 'Core Cut'  he is doing himself a huge injustice.


      A) He will have no idea if there are other roofs below.


    B) If there is one other or even two other roofs below, the contractor will


    not know on how many dumpsters will be required for the removal and disposal, of the top roof and whatever


    might be underneath.


     C) If there arethree roofs that have to be cut off , labor cost for the tear off will be three


    times more than if there was only one roof  and the contractor will have to pay for 3 times more in dumpster


    fees.


3. If there is no "Core Cut" taken the contractor will not know if the is wet insulation below.(unless your willing to


    pay for a "moisture scan").


4. If there is no "Core Cut" the contractor can only hope for the best scenario, which would be, the roof that is


    exposed is the only one and the deck below is steel (usually 22 gauge prime painted "B" decking)


5. Finally if there is no "Core Cut" , and the existing roof is removed and properly disposed of the contractor will


    have no idea on how to secure the new insulation . If the 'deck' is steel the new insulation (which is not wet),


    can stay. You will only have to pay for new insulation provided by the contractor that is wet ! 


6. If you have a concrete deck the contractor should install all the of the new insulation by adhering it to the


   concrete with a foam adhesive.


7. If a 'Core Cut' or multiple 'Core Cuts' were taken , you and the contractor will learn exactly how many roofs


    have to removed , if you still have a lot of dry insulation that can stay and how much wet insulation will be


    disposed of and how many pieces of new insulation will be needed, & how to secure the new insulation,


    preferably , two layers of "Polyisocyanurate" with an R-value = 20, can be secured with a three inch round


   ' Galvalume ' plates with a minimum of a 4.5 inch screw in the middle of each plate, that will fasten


   the two layers of insulation and will bite a minimum of 1/2 inches into the 'steel deck'.

    This roof will last a minimum of thirty years , EPDM Fully Adhered rubber roof.

The innovation of seam tapes in the 1980s to replace liquid adhesives has resulted in reduced reliability on contractor workmanship, greater productivity for the contractor and enhanced performance for the roof system and building user.  Self-adhering components that have factory-applied adhesive tape) have increased roof system quality, especially in more  problematic areas such as flashing installations.

 Installation equipment has evolved as well. Ergonomic innovations have reduced crew force fatigue and have enhanced roof system installation and performance.

 Following  over 15  years   off-market  testing  verify  performance, 90 mil  EPDM  membranes  have  recently  been  introduced  into the  market. This  highly  puncture  resistant  and  tough  membrane  offers the thickest layer of monolithic waterproof protection in the roofing industry.

The 90 mil EPDM roof systems are redefining the roofing industry and the expectations of architects, roof consultants & building owners.

                          "Thirty-year warranties based on historical performance are now available ".        

This  Is  the only  long - term performance  guarantee in the roofing  industry, and  can  include  warranty  coverage  for  punctures, hail  and wind speeds up to 100 mph.

White EPDM combines the high-performance standards of traditional EPDM with a highly reflective, environmentally friendly surface designed to cut energy costs. In addition to the oils and the polymers used to make an EPDM membrane, another ingredient is added to the mix to enhance UV resistance.  With white membrane titanium dioxide is typically used to reflect UV rays and prevent it from attacking the polymer. When used appropriately, usually in warm climates, white EPDM can reduce air-conditioning costs without sacrificing durability of the roofing system. Because of its reflectivity, white EPDM is installed using mechanically attached or fully adhered systems.

 Historical Timeline


EPDM membrane formulations have remained relatively constant for the
past 40 years, with roof systems installed in the 1970 's   still performing well . Even so, EPDM manufacturers remain committed to continuous product innovations. In response to technological advancements, membrane research and contractor requests for more ergonomic products, EPDM accessory products continue to evolve in order to meet the demands of the industry.
