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? Keenesburg
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.
KeenesburgA roof shingles estimate helps us to estimate the number of shingles to order when laying a new roof. Either a professional roofing estimator or a contractor will let you know the number and quantity of roofing shingles that you need for a given job after taking relevant measurements of your roof. There are several methods to do this. Here we will explore the more common methods.First, let's understand how the shingles are packaged and sold. Shingles are sold in bundles. For example take the 3-tab shingles packed in bundles. Three of these bundles will generally cover one roofing square. Roofing Square is the term used in roofing industry to denote 100 square feet. The shingles are packaged in plastic or paper and can easily be transported by one person. The shingles that weigh more may be packed with less shingles per roofing square. So, you will need more bundles per roof square. The roof shingles estimate will help us to find out how many of the shingles or bundles you need to cover the roofing area. You could use two methods to do this. The measurement method is one and the other is the sheet-count method. In the measurement method either you or someone else has to climb the roof and measure every plane where the roofing shingles will go. Suppose you have a rectangular roof then it is easy to measure the length and width and just multiply both to get the required area.For sloping roofs and other shapes it is a little more difficult to arrive at the area in straightforward way. You need to adopt indirect estimation methods. First measure the floor area making suitable provision for overhang. Next, for slopes you have different area multipliers. These numbers when multiplied with the floor area gives an estimate of the roofing area. There are 3 different slope multipliers depending on whether your roof is low, medium or a steep roof.The sheet count method on the other hand uses a simpler technique than actual roof measurement. It uses sheet panels which are of standard 4 * 8 measures. The roof is simply sheathed with these sheets and then you count the number of sheets needed to cover the roof. In some parts of the roof the panels will have to be cut to accommodate the shape of the roof. To arrive at the roof area, add up the full panels and what's remaining after the cuts on the remaining panels. This is much quicker and simpler method to arrive at the area of an irregular roof. Also, with the sheet method, all you have to do count the number of panels and you can order the bundles of shingles based on that number of panels. This is a simple and easy way to arrive at the area. It may be a crude method but is very effective and fast.Another method that has been frequently used and works for homes with old roofs is to simply count the number of shingles on your roof. Just count the number of rows from eaves to ridge. Also, count the number of tabs from edges to eaves. Each tab is one foot in length. The exposed area of each course is 5 inches. Multiplying the numbers gives you the area of shingles needed.
Roof Shingles Estimate - An Accurate Assessment For Ordering ShinglesIn 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.
