Technology has changed over the years. You should consider the options for your business' roof based on a few facts and suggestions. Rolled roofing dates back to 1893 in the United States which consisted of long strips of felt covered with asphalt and a fine layer of stone (crushed).
Individual shingles were added by the early 1900s, but in the 1950s, the 3-tab variety was introduced, making it a popular organic/natural choice for roofing material. However, the 3-tab choice could only withstand 60 mph winds. Things have changed as you will see from the following descriptions and explanations.
Laminated Shingles: As a moderate type of roofing material, the laminated shingle has added thickness and weight because of its backing made of padding. However, it isn't eco-friendly because it contains petroleum based products. The shingles overlap each other and are nailed to the roof during installation. If you see what appears to be a shingle, it is a tab. With technology, the roof is formed with various widths and random gaps. It can withstand 110 to 130 mph winds.
Metal Roofing: Metal roofs are adhered with screws to make it more wind-resistant. Homes in Florida are a good example of how metal can withstand the hurricane pressures. A witness with a metal roof on their Florida home stated that out of 92 homes, only 2 homes were saved during a hurricane, and one was theirs. The roofing carries ratings of 140 mph wind-resistance.
Concrete Tiles: Winds in excess of 125 mph can remain under warranty for 50 years. The tiles are sturdy but the adhesive used can cause problems if they aren't properly installed.
Asphalt Shingles: You can receive a wind warranty if the shingles are installed as indicated by the manufacturer's requirements. Asphalt shingles are capable of resisting wind up to 130 mph.
Protect the Structure: You can do several things to ensure your roof will remain intact. For example., you can brace the roof trusses. Check to be sure the plywood roof sheathing is installed correctly. Finally, if you are in danger of hurricane force winds, it is essential to install hurricane straps.
Before you make a decision, you need to have the underlayment and shingles removed so the sheathing can be inspected. The screws should be stainless steel if you live in an area that is around 3,000 feet from salt water. With these suggestions, your business should be well-advised concerning which roof will be the best for your windy city. Go to websites that discuss roofing for more information.
