However the lifting force is not specified and rarely is the lifting dimension justified.
Roof brittle test.
On roofs that have borderline hail or wind damaged it is important to perform a brittle test in order to determine whether or not the roof damage is repairable and may help you reach the 25 required to be deemed damaged from the peril wind or hail that will allow a total roof replacement.
Some inspectors refer to the brittleness test as un bonding a field shingle and lifting the end of the shingle until it is x inches above the roof surface.
If none of that happens pass.
When testing rubbers for impact brittleness use test method d2137.
Astm e1105 and aama 501 2 test methods are good overall methods commonly used to test exterior walls sloped glazing and shallow pitched roofs to help identify leak sources.
The brittle shingle test is a super scientific testing method whereby an inquisitive person picks up a shingle tries to fold or bend the shingle up to a 90 degree angle and then checks to see if the shingle breaks or bends.
Pour seventy degree water over shingle to tested wipe damp dry use laser pointer thermometer to insure shingle is over 50 degrees.
Spray testing is the use of controlled water flow deposited on building components in a manner that simulates normal to severe weather conditions.
If the shingle breaks then the shingle is brittle and the roof probably needs to be replaced.
U test the shingle by lifting bending it at a 45 angle.
Call allstate supervisor for check list so you can comply with their needs.
Two routine inspection and acceptance procedures are also provided.
If you ever had a ladder assist company called hancock called out to your adjuster meeting to climb the roof to inspect for hail or wind damage.
It is then raised and lowered 45 degrees three times.
Break off a large piece to shove in.
1 1 this test method covers the determination of the temperature at which plastics and elastomers as defined by terminology d883 exhibit brittle failure under specified impact conditions.
If it cracks creases or breaks during the test or at the 45 fail.
Each slope stands on it s own at this point until depends on carrier you ve hit the 65 rule.
That slope is not repairable due to brittle.
That slope is repairable.
Pinch a small corner of a shingle between your thumb and forefinger try to fold or bend that corner up to a 90 degree angle if.
