Ice build up/removal/loss of warranty

Hi-we removed ice (about a foot thick) from my parents metal roof in NH because it was leaking where 2 different roofs (house and then porch off of house) came together. Removal of snow and ice was with a snow rake. However, in doing so, the installer says that the 25 year warranty is now gone,as the snow rake put 4 little holes and scratches in the roof. He plugged the holes and will come back in the spring and seal the holes. Can you talk to me about how flimsy metal roofs are that they can not withstand a roof rack pulling snow and ice off of the roof? Thanks for your help-I dont know exactly what kind of metal roof, realize there are many however question the sturdiness of metal roofs. Should there also always be a ventilation area as this roof was installed right over a shingled roof.

There are many types of metal roof systems, each designed to meet certain needs. We always recomend that one analyse why the exixting roof failed and correct those issues when selecting a new roof covering. You obviously have heat loss and it is probably a vaulted ceilint. Ventilation is required by the building code under the roof covering for vaulted ceilings and would go a long way to resolve your current situation. The strength of a metal roof is as much dependant on the profile as the thickness. There are thicknesses of steel and profiles that will resist the traffic you discussed as well there are better paint systems that provide more resistance. You may be at the lower end of thickness and paint and it will affect the durability somewhat. I would not panic as yet and the contractor should be able to seal the holes and scratches if large enough can be touched up with paint. I would take steps to install a proper heat cable in the area to do away with the ice buildup and reduce future concrens.

Thank you so much for taking the time to respond to my concerns. Seemed a little strange that the roof couldnt take some basic housekeeping measures. The fact that the warranty is now gone is not a huge issue? since in theory the roof should last the 25 years anyway. Right? Appreciate all of the time spent on this site-very helpful to read all the scenarios for future reference.
