    Hail is an act of God. The bible speaks of whole cities destroyed by hail. Many people in the weather business predict this will occur again. I also think it will. Nothing except stone and earth will survive very large hail.

    I am not an engineer nor an expert, but an adjuster who has seen very large hail in the USA on over 20,000 buildings over many years and it all comes down to the hail stone or the large chunks of ice that comes from over 50,000 feet, sometimes with tornadic winds.

    No material that is made by man will survive if the hail is large..... just relax, buy windstorm insurance as you have a good chance of being hailed out ever 15-20 years or sooner.

    Me-an...all you have to do is sign up & pay for adjuster licensing classes, obtain the license for your state and then get on board to work claims for  every vendor that handles losses in your area.  This will guarantee your roof safe from damage.   It would be cheaper and easier though if you just follow Ray's advice.

    Mike,  I do believe that was just a clever way of getting some free advertising, just a good hunch.

    Success is not final, failure is not fatal: it is the courage to continue that counts.

    Tom I thought the same thing when I pulled the site up.  While we are on the topic of most hail resistant, I always look out the windows when I am in a tall building and look at the roofs below. It seems accross the US most appear to be a mod. bit. (type) with a white slate coat, about 30" wide and torch down with a lap seam. Overseas I have seen a black rubber type with soil on top and a garden growing. Many of the major rubber companies in the world seem to make some type of membrane with their own brand name. Its very hard to walk on a large commercial roof and tell what the brand name is and I usally ask the insured who has the history of the roof.

    There is no way to protect against hail (as many here will tell you also). Shingle manufacturers test hail "resistant" shingles by droping ball bearings onto the shingles. This is a flawed test. Have you ever seen a smooth hail stone? Hardly. Most hail stones are jagged, unusual in shape and size and sometimes have points.

    After 3 generations of roofers within our roofing comany here in Texas, I have yet to see a shingle hold up to a big ole South Texas hail storm.

    Some shingle manufacturers make "impact resistant" shingles but they only hold up to hail so large. I have seen 50 year laminate shingles sustain hail damage when less than 5 years old. The recent hail that swept through the Lino Lakes area 5-25-08 was amazing. The only siding not damaged was stucho, hardie board and brick. If you an any grade vinyl, aluminum, or steel you had damage. All the roofs I have been on were badly beat.

    Not sure if a link is ok but here are pics I took of a roof in Lino Lakes, MN the other day,

    On the last page some pics of the twister that blew through Hugo also on 5-25-08.

    Right now hail is moving through the Hugo area, amazing. Getting calls on roofs that were replaced in the last 1-4 weeks from hail. I still have a few jobs to do from the 8/24/06 hail storm and several from the hoards of 07 hail storms.

    I would also like to add, that even though most insurance companies regard granule loss as a "Cosmetic Only" defect, the impact will eventually create substantial granule loss over the next several seasons of normal weathering, due to the impact point and loosening of granules.

    In most areas, unless the cat is so wide spread, the time limit for reporting damage is one year, as you all know very well, but the actual symptoms may not be readily visible until some time later than that one year limit benchmark.

    Dramatic photos Doug.

    Exactly right! And don't buy into Haag Engineering's theory that a commercial roof can't damage unles the hail is> 2". It's a lot more complex than that - it depends on the hardness of the hail, the outside temp, wind, shape of the hail, etc. I saw every commercial roof in Spur Texas get severe damage from marbe sized hail - it happened in a freak storm in February when the temp/roofs were in the 40's (brittle asphalt) and the wind driving the hail into flashings at 50 mph.

    The best way to protect a roof from hail damage is move it to Winnemucca, Nevada.

    The only way to protect a roof membrane from large hail stone damage is: do not have a roof membrane.
