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? Kinikinik
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.
KinikinikIn 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.
How to Identify and Repair a Hail Damaged RoofHow much damage to your roof can come during a hail storm? In Georgia, hail storms are not that uncommon and many homeowners visually see hail several times during the year. That is the case in metro Atlanta, where the last few years have resulted in elevated hail activity.Most people are somewhat aware of the damage hail can cause, in particular the larger variety of hail that is notorious for damaging and denting cars. This awareness doesn't always fully translate into the impact a hail storm can have on your home's roof. While you can visually see the damage to your car after a hail storm, you can't always see the damage to a roof. The damage you can't see can put the longevity of your roof at risk.Roof replacement due to hail damage is one of the most expensive fixes for homeowners and insurance companies. Hail can vary in size dramatically, falling as small as the size of tiny pellets, or as large as baseballs. It is typically the larger hail that can cause enough damage to your asphalt roof to justify a roof replacement. Asphalt Roof Shingle Damage from Hail:Hail damage to asphalt roofs occur when hail beating against the surface of asphalt shingle results in the protective granular surface of the shingle to loosen and potentially fall off. When the granules are loosened, the asphalt shingles loses some of its protection potential and becomes vulnerable to additional damage.- Note: Damaged asphalt layers can potentially allow water seepage into the roof.- Tip: If the granules of an asphalt shingle are removed by a hail storm, the shingle's longevity can be severely diminished.Signs of Hail Damage to an Asphalt Roof:- Bruises or small dents in the asphalt shingle - Granulation is displaced exposing the asphalt - Granulation has settled at the base of your downspouts - The spots hit by hail usually leave a soft spot in the shingle - Significantly damaged metal air vents on the roof indicate similar hit pattern for roof - Damage and denting of siding, or guttersIf my Roof is damaged, how fast should I replace it?There is a misconception if your roof sustains damage from a hail storm that your roof needs to be replaced immediately. You'll find some conflicting evidence online from other roofers that advise immediately replacing your roof. In Georgia for example, any reliable roofing contractor in Atlanta should tell you otherwise. Typically the damage sustained from a hail storm will pose no immediate threat to your roof. The threat is in the longevity of the roof, because hail can dramatically decrease a roof's life expectancy. The deteriorated protection from a roof that is not expected to last its full life is why insurance companies will authorize the replacement of your roof.Will Homeowner's Insurance Cover a New Roof?This answer varies by the coverage on your homeowner's insurance policy. For some homeowners the answer is "yes." If you believe your home has been the victim of hail, contact your insurance company to determine if your policy will cover the damage. For many homeowners they will be able to have the roof repaired, or replaced and will need to pay a deductable. - Tip: If you are unsure if you homeowner's policy covers hail damage to your roof, contact your insurance company.Caution: Avoid Storm Chasers!Homeowners need to beware of 'storm chasers.' A storm chaser typically consists of an out of town roofing contractor that goes door to door after a hail storm soliciting for business. While it may seem tempting and convenient, these roofers can do more harm than good. Make sure any roofer you look to work with has a good reputation in the community. Look for a roofer that is located locally and check references. Look for references that are over a year old and ones that are more recent, within the last 30 days. Finally never give a deposit for a roof. A reliable roofer will only ask for payment once the roof has been complete.If you think your home has sustained roof hail damage, get a professional opinion. Experienced roofing contractors should be willing to provide free roofing estimates upon request.
