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? Kelim
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.
KelimIn 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.
Hail Roof Damage - What to Look ForPeople often presume that spending time and effort identifying the right roofing option and getting information relating to all the choices available in the market is a most important task. The biggest problem is that people relaxed once all these tasks are completed. The end result is that they loose valuable money when they do not pay specific attention to the roofing estimate.The cost of material, labor and all other incidental and ancillary expenses shall be clearly defined in the roofing estimate. Once this is done, the estimate forms the basis of all future work. Choosing the best option but not paying attention when the estimate is being prepared is no different than signing up with the first service provider you find. Keep the following factors in mind when you obtain a roofing estimate. It should be in writing and should be formal estimate. A few figures roughly sketched on a rough piece of paper is not an estimate. From the name of the service provider to details of each and every task-everything must be clearly specified. Remember that those service providers who offer vague estimates often make use of this characteristic to increase the cost. On the other hand, a service provider who offers a specific roofing estimate is a much better bet.The next factor that you should consider is whether the estimate clearly covers each and every task that you want to be done. There are many service providers over very low estimates by skipping major tasks. A roofing estimate that simply covers the cost of installing the tile but does not cover the cost of the tile is of no use whatsoever. Make sure each and every specific task that you wish to carry out is clearly specified in the estimate. If you want to make sure that you deal with the most affordable service provider, you should get estimates from various service providers. It is your right to get an estimate of the work to be done at zero cost. Hence, never pay anybody just to get an estimate of the work to be done. Dealing with such expensive professionals is not the smart way to proceed.The advantage of using the web is that you can compare the various estimates you have received and determine whether it is indeed accurate and reliable.
