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? Glen Haven
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.
Glen HavenIn 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.
Roof Hail Damage - 4 Tips for HomeownersBeing professional roofing contractors we know all too well the damage hailstorms can do. Hailstorms produce balls of ice ranging in size from a few centimeters up to nearly 6" in diameter. A 6" piece of hail is pretty rare, and would certainly do major damage to your home, but even the more common, smaller hail frequently does enough damage to roofs and siding to require major repair work.Hail damage is not always easy to detect, especially if you have a two or three story home and cannot easily access your roof. Hail damage can leave your home exposed to potential water damage as well as limiting the lifespan of your roof. Because of this you should identify and deal with damage as soon as you can. If you wait too long you may also be denied by your insurance company when you finally get around to filing a claim for the repairs. Have there recently been any hail storms in your area? Do you suspect your home may have been damaged? The following steps will help you determine if there was any damage and outline the steps to getting it repaired. Step One: Check around the exterior of your home for visible damage. Look for things like freshly damaged paint or dents in the siding. If you are able to safely access your roof, look for missing shingles or shingles with blisters or dents. Also, check for dings and dents in your gutters and downspouts.Step Two: Check inside your home for visible damage. New water stains on your ceiling or running down your walls is a problem that needs to be immediately addressed! If you don't fix a roof leak in a timely fashion you could end up having to completely replace your roof, in addition to major repairs do to water leaking into your home.Step Three: Contact your insurance agent right away and make sure they are aware of the damage. They will probably have one of their adjusters out to evaluate your home and prepare a cost estimate for the repairs.Step Four: Contact your own local roofing contractor for an independent evaluation. Even if you trust your insurance agent and their adjuster, you should always get a second opinion from a roofing contractor you trust. Because they don't work for the insurance company they should be less biased in their assessment. Usually the roofing contractor you contact will be willing to communicate with the insurance company if there are any discrepancies in the two evaluations. Step Five: Get everything in writing. The roofing contractor you decide to hire should provide you with a contract detailing the work to be done and what it will cost. You insurance company should also provide you with paperwork about the details of your claim. Cover yourself by getting as much as you need to feel comfortable in writing.It only takes a matter of minutes for a hailstorm to do an amazing amount of damage to your roof. As soon as the storm passes begin the process of determining the damage and contacting your insurance company and roofing contractor. If you wait too long it may be too late!
