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.
Understanding Your Roof Replacement EstimateWhen you are ready to install a new roof on your home you should always prepare a list of questions to ask the roofing contractor before your scheduled appointments. There are many different styles of roofing materials so you should take some time, and look online for the roofing type you want on your home.What Are The Questions To Ask The Roofing Contractor? What Type Of Roofing Materials Do You Sell? What Type Of Insurance Do You Have? Do You Have Any References? How Many People Will Be On The Crew? How Long Have You Been In Business? How Long Will This Roof Installation Take? What Is Your Workmanship Guarantee? Does My Home Need Additional Ventilation? What Are The Different Roofing Types?There are several roofing materials from asphalt roofing, steel or metal roofing, ceramic roofing, and single ply rubber roofing. Most residential homes have either asphalt or metal roofing panels as the roofing products, and on the flat roofs like dormers single ply rubber is also used. In tropical or different regions ceramic or terracotta roofing materials which can be used. All of these products are great for waterproofing, and are very easy to find information about online. What Roofing Materials Are Best?In different parts of the country roofing materials will change because of weather conditions. In Maine people use a lot of steel roofs because of the heavy snow fall. In Florida the choice of roofing is tile, and because of the heat, and asphalt shingles are used all over the country. There are also special asphalt roofing shingles for high winds along the coast, and flat line wind storms like in North Dakota and surrounding areas.What Insurance Is Required For Roofers?As you can understand roofing is a very dangerous job, and not all liability insurance is the same. Roofing liability insurance is usually about 200 percent more than basic carpenter liability insurance, and excludes roofing completely. I have seen many insurance binders over the years from roofer who has only purchased basic carpenter type liability insurance, and when a problem occurs the home owner will not be protected or covered under this type of policy. As a homeowner you need to have the insurance company send you a copy in the mail with your name on the binder, and make sure that the policy includes roofing.The next insurance that the roofing contractor should have is workman's compensation insurance, and this is where you could lose your home if someone is killed or seriously injured. In most homeowners insurance policy's it is clearly stated, that anyone you hire to perform work on said property must have workman's compensation insurance. And you are responsible to make sure that they have this workman's compensation insurance before you hire them to start the work on your home.What Should I Need For Ventilation?The reason a home should have ventilation is to remove the moisture from the home. Prove fact is that each person in the home permeates about 3 gallons of water a day. From showers, to cooking, and breathing water vapor is created and need to be able to leave the property. One of the largest reasons is to allow the attic to breath, and remove all the excess heat from the attic. Roofing manufactures want the attic to be the same temperature as the outside at all times. This adds life to the roofing materials but also helps you save money on your heating, and cooling cost. How Many Estimates Should I Get?You should get at least 3 roofing estimate from reputable roofing contractors to ensure the size of the roof, and compare the roofing materials, and pricing. Caution, do not only make your decision on the price, and you as the home owner must assume some of the responsibility if you insist the contractor lowers his price in which he cannot possibly by the materials, and supply the necessary labor to complete the job correctly. To do the job right the roofing contractor will need to pay for the materials and insurance then hire qualified installers to effectively complete the roofing work. Plus the roofing contractor will need to pay for his tools, equipment, and his vehicles plus additional over-head to manage the job correctly.
