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? Drake
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.
DrakeAccording to East Tennessee SKYWARN, "Hail is a form of precipitation that occurs at the beginning of thunderstorms. They consist of near spherical pellets of ice and snow, usually combined in alternating layers."By this definition alone, you can already imagine what potential damage hail can do to your home, specifically your roof. And, if hail can damage your roof, just think how it can damage your vehicle. In fact, big hailstones that fall with force have been known to cause fatal harm to humans and animals.Scientists have been trying to reduce the destructiveness of hail by injecting large quantities of silver iodide into a thunderstorm. They are trying to overseed storm clouds so that smaller hailstones will form. This will prevent them from developing into large hailstones. But as of this date, results remain inconclusive.What damage can hail do to your roof? Hail damage on vehicles can easily be seen but the damage that hail does to your roof will not be as obvious. Hail damage results in a random pattern of strike marks in different sizes. You may find dents, cracks or bare asphalt (if you have asphalt shingles on your roof). Additional signs of hail damage to an asphalt roof could be: granules that have settled at the base of your downspouts, metal air vents that have significant damage and damaged and dented siding or gutters.Generally, hail has to be at least 1 and 1/4 inches in diameter before it can cause damage to wood shake shingles or heavy composite shingles. Hail that is 1 inch in diameter may damage lightweight composite shingles. However, if you have deteriorated composite shingles on your roof, hail that is less than 1 inch in diameter can easily cause damage. What do I do if my roof has been damaged by hail? Most hailstorm damages are cosmetic and won't have any adverse effects on your roof. However, moderately severe hail damage that strips shingle of their coatings may affect the longevity of your roof and this may qualify for repairs covered by your insurance. If the damage will cause leaks, exposed areas should be covered with tarps held in place with wood strips and nails. When you can access the roof, you should permanently repair the sheathing and replace missing and damaged tiles, shingles or shakes.Are there available hail-proof roofs in the market? There are hail-resistant roofs but to this day, you cannot find any hail-proof roofs in the market. These hail-resistant roofs have Class 1 through Class 4 hail-resistance ratings, 1 being the lowest and 4 the highest. These roofs are rated based on test results done by The American Society of Testing and Materials (ASTM). A steel ball is dropped from a predetermined height and the damage that the roof sustains is then measured.There are several roofs that carry this rating but the most likely to endure hail with minimal or no damage would be concrete tile, composite shingles and metal roofs. When you purchase a roof be sure to check with the manufacturer to determine what hail rating is given to a particular product.What damage can hail do to your vehicle? If hail can damage your roof, then an exposed vehicle can sustain much damage. Dents will most likely be the most common problem. If your vehicle will be exposed to large hailstones however, there is a probability that you might end up with broken windows and/or a broken windshield. The good news is, with your vehicle, you can take preventive measures so that it will not be damaged by hail.What can you do to prevent your vehicle from being damaged by hail? When hail is in the weather forecast, put your car, boat or RV into a garage. If you have no choice but to leave your vehicle outside, cover parts of the vehicle that is most susceptible to hail damage, with thick blankets. These would be the roof, hood, trunk, windows and windshield.In cases where you are suddenly caught in the middle of a hailstorm while driving your car, seek cover in a covered parking lot or garage. Another option would be to go under an overpass or any place with an awning. If you are on a long stretch of road with no cover in sight, pull off the highway, park at the side of the road and just wait it out.What do I do if my vehicle has been damaged by hail? Contact your insurance company and report the damage immediately. Find out if your insurance has a preferred body shop that can do the necessary repair to your vehicle. If you want to choose the repair shop yourself, make sure that you will have your vehicle serviced by a reputable facility. Make sure that you discuss with your insurance company and your body shop, what kind of repair should be done to your vehicle. Ask how long the repair will take. But if several vehicles were damaged in your area during the hailstorm, do not expect the repairs to be finished immediately. After repairs are made, make sure that everything was done to your satisfaction. Check for remaining dents and scratches before taking your vehicle back home. Before having your vehicle repaired, you must check if the repair shop guarantees its work. Make sure that you get the guarantee and contact information in writing. If you find any flaws in the repair, you should be able to bring it back to them at no additional cost.Hailstorms are part of nature. While most parts of the world may not experience this kind of weather, those who live in the middle latitudes are not so fortunate. If you are one of those people and have no choice but to live with it, just do the best you can to protect your roof and your vehicle by following the simple steps mentioned earlier.
Estimating a Roof Job - A Roofing Business Pricing Guide For ContractorsIn 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.
