Roof-pull-test, com-ten's roofirst pull tester is a valuable solution to test fasteners on the roof. it is used to prove the fastening integrity for existing or new roof construction. it is designed to record and document on site pull-out values. it can be used in horizontal or vertical tests in all types of substrates.. Com-ten is the world's largest company and the leading manufacturer of pull testers for on-site tests in more than 50 countries., when using fm 1-52 test, the maximum allowable roof surface deflections are one quarter of an inch for pressures to 60 psf and one half of an inch for pressures between 60 psf and 120 psf. whereas, when using astm e907, a one inch deflection is allowable at any test pressure..
