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? Norfolk
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.
NorfolkIn 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.
What To Look For In An Estimate Of Roof RepairGetting a roof repaired or replaced is something most of us homeowners dread, and when the roof does need repair, it is important to get not only the finest quality materials available but the best price on installing those materials as well. Most of us will start the process by getting an estimate of roof repair from a few local contractors, and it is important for all homeowners to learn how to read this important document properly.Of course every estimate of roof repair will look somewhat different, according to the company who prepared it and the nature of the job. The estimate for patching a hole, or replacing a bank of shingles, for instance, can be a fairly simple and straightforward document, while the estimate for installing or replacing an entire roof can be quite complex in nature. No matter what the cost or complexity of the job, however, there are a number of things to keep in mind when reviewing all those competing roof repair offers. Perhaps the most important thing is to make sure that each estimate of roof repair is bidding on the same job. Before you go out to get those estimate, it is important to write up the requirements of the job, including when work must begin, when the repair needs to be complete, and any preferences you may have as to roofing materials. Spelling out all these requirements ahead of time will help you to make sure you are comparing like to like as you sort out the prices of the various estimates.It is also important to consider the reputation and reliability of the roofing contractor. Not all roofing contractors are equally reliable, nor are all equally skillful and knowledgeable. If you have a specialty roof, such as a tile roof, a rubber roof or a metal roof, it is important to choose a contractor who has expertise in that specialty material. A general roofing contractor may not have all the skills, tools and expertise needed to complete a complex repair on the more unconventional roofing materials on the market. After you have reviewed all of the roof repair estimates and narrowed the choices down to just a few, it is a good idea to take a couple of minutes to chat with each of those candidates. It is often possible to get a real feel for the quality of the work someone will do just by meeting with them, and roof repair is no exception. While the estimate of roof repair can give you an idea of the price, only a face to face meeting can give you the gut feeling that can be so important in the world of business and in the world of roof repair.
