When homeowners choose to repair a roof or replace that roof with asphalt during the cold winter months, they’re often plagued by worries that their family will freeze before the job is completed. In the same vein, those starting a roofing job in the sweltering summer months worry that they’ll be facing heat stroke. These concerns are perfectly normal and common among many homeowners looking for roofing fixes or roof replacement contractors.

metal shingles cost Flat roofs are often the most susceptible to hail damage. In fact most types of flat roof do not even come with a hail rating. This either means that the material has not been tested, or that it wont hold up long under hail storms. This does not mean that there aren't flat systems that hold up admirably.To show the differences in roofing materials, I am going to compare three common flat roof systems. One is rubber roofing. This stuff is usually around a half inch or more thick and instead of being adhered to the roof, it is mechanically fastened with screws. This requires a further layer of insulation to complete the roof system. My Denver roofing company found hundreds of large diameter hail impacts because of the soft rubber material in one example. However, there were no leaks on this building. PVC roofs do not hold up as well from hailstorms because they are so brittle. You actually want a slightly flexible material if that material is not very strong. In once case, our roofing contractors in Denver found impacts that looked like shattered glass. Hail can go right through thin PVC. This immediately causes leaks and water damage. So make sure you use thick, impact resistant PVC in hail regions.Rubberized asphalt is a construction system that performs well under hail conditions. Rubber is mixed in with the asphalt to increase the life and elasticity of asphalt. Asphalt's main weakness is that it dries and cracks over time, so this attempts to combat this. It will not completely protect underlying fiber glass roofing, mainly because of how thin it is. However they generally do protect from hail pretty well. My roofing contractors in Denverrecommends gravel surfacing to be added to the bitumen or rubber for maximum weather protection. Gravel is very strong compared to other built up roofs. A rock will always be harder than ice. The rocks absorb the energy from the hail instead of having the fragile roofing material do the job. Generally a well built gravel built up roof never has any problems with hail damage. Other strong roofs include metal roofs, which may dent but rarely need to be replaced. Coated acrylic foam roofs are actually some of the toughest roofing materials out there. High density foam will absorb and dissipate pretty much any hail stone. To really get a strong roof, you could substitute river rocks for gravel on any of the built up roofs. This results in a much heavier but basically impervious roof.

residential roofing options In May of 2011 the Roofing Industry Committee on Weather Issues, Inc. conducted two investigation programs covering the effects of high wind and hail on various roof surfaces. The Roofing Industry Committee on Weather Issues, Inc. (RICOWI) was founded in 1990 as non-profit focused on identifying and solving issues associated with wind damage. Since then RICOWI expanded to cover other weather related issues. The RICOWI recently completed an inspection of over 100 DFW area homes to determine the effects of hail on various roofing systems.Meteorological DataOn May 24, 2011 several storms containing large hail passed just north of College Station, TX (Dallas/Fort Worth). According to the National Climatic Data Center, reports of hail 2 inches in diameter and larger were reported over the area. Large hail over 4 inches in diameter was also reported to damage airplanes and nearby airfields.Investigation MethodologyTrained inspection members identified affected roofs by properly identifying dents and other impact marks, known to be hail related. Property owners and other eye witnesses were interviewed to verify the extent of hail impact. Trained inspection members identified affected roofs by properly identifying dents and other impact marks, known to be hail related. Proper data was then collected and analyzed. The data included metrics covering location, roof construction details, pitch, estimated hailstone size, and severity of hail impact. Impact severity was measured on a scale of 0 (no real damage) to 5 (severe damage and potential leaks as a result). y owners and other eye witnesses were interviewed to verify the extent of hail impact.Investigation FindingsLow Slope Roofing SystemsA focus of the investigation was to determine the differences between roofing products rated for impact resistance and those that were not. It was found that low slope roof systems that had membranes that were firmly supported by gravel or stone ballast performed the best.Asphalt ShinglesAsphalt shingles that were rated as impact resistant did perform better than those not. Out of the roofs that were tested 75% of the impact resistant roofs were rated in the damage categories 0, 1, or 2 (the lowest damage categories). The average damage rating for impact resistant roofs was 1.3. The damage rating for non-impact resistant roofs was 2.5. Older roofs also showed more damage than newer roofs within the same area due to additional wear and tear and aging.TileTile roofing systems performed well. Even though hail sizes were estimated to be between 2 and 4 inches, very few tiles had any damage. The damage noted on tiles is a pattern of multiple fractures from a single hailstone impact. Tile roofs older than 12 years also showed no noticeable differences in performance, probably due to lasting materials of clay and concrete. Metal RoofsMost metal roofing systems also performed well. Of all of the metal roofs tested only 1 had severe damage where roof had distorted sides. None of the metal roofing systems, where raised, galvanized steel, or standing seam, had any evidence of leaks or punctures.Final ResultsHailstone damage was easily identifiable by the trained personnel on many varieties of roofing types. Hailstone size is more of an indicator of the extent of damage than hailstone number. Across the board impact resistant products performed better than standard products. Roofing systems that possessed a more substantial substrate also performed better than those without.ConclusionIt appears that roofing systems that provide a complete system of protection from hail include impact resistant materials, a solid substrate backing, and a proper installation. repair leaking roof
