You’re a homeowner and determined your home’s roof needs fixing or needs to be improved with a replacement roof. You’re all set to get moving. What’s the optimal way to get a high quality roofer who will accomplish a good job? What could you look for in a roof contractor or contractor to obtain this work? Evans
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.
EvansIn 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.
Roofing Hail Damage - Things You Should Know Before You Hire a Roofing ContractorRoof damage due to hail is quite common. If you too own a home, you can save a considerable amount on your roof repair by taking some proactive steps to protect your roof against hail damage. By taking definitive steps to mitigate the affect of these frozen balls of precipitation on your roof, you not only ensure longer life of your roof but lesser roof repair expenses as well. For instance, it will be a good idea to invest in hail resistive roofing materials.To help you judge the seriousness of matter you should know that in the recent times, hail storms have produced baseball-sized hail. These have already caused extensive damage to roofs of residential properties in major cities as well as the suburbs. Given the size of the hail, you can easily imagine the degree of damage that they can cause to your roof, especially if it is made of asphalt shingles. It loosens the protective granular surface of the shingles and makes them highly susceptible to cracking and breaking. Unless you remove the hail from your roof almost immediately after the storm has ended there is a high chance that your roof will also show signs of water seepage. This in turn can lead to dampness, leaking roofs and discoloration of the ceiling and the attic.In order to fix the hail damage caused to your roof, call a professional roofing contractor in your area to do a thorough inspection and identify and remedy any roofing problem caused by hail. The down spouts are most likely to be show signs of hail damage. Hence inspect them more carefully. If you see any dings in gutters, you need to ascertain the extent of hail damage caused to them and fix it. In case your roof has undergone serious wear and tear due to a hail storm, you can file a claim with your homeowners' insurance provider to recover the amount that you will end up paying for roof repair or replacement. If you install a Class IV hail resistant roof in your home, you can not only restrict the degree of hail damage to your roof but also lower your home insurance premium significantly. As for repairing roof hail damage, it is strongly recommended that you contact certified contractors who know their job inside out.
