Roof Damage | Repair Roof Damage | Roof Ventilation

Poor Roof Ventilation Can Cause Shingle Damage There is a great deal of moisture that accumulates in a home. This moisture, like heat, rises and works its way to the top of your home. Without adequate ventilation, this moisture would accumulate and cause the top of your home to deteriorate. Ventilation allows this moisture to escape and helps bring balance to the moisture that accumulates on the roof as well. Ceiling fans, vents and ridge vents all make up the ventilation system that ensures a home, attic and roof have ample air to release moisture. The roof ventilation systems consist of both intake and exhale vents. These vents balance the air between the roof and the attic. Why Do Roofs Need Ventilation? If your home doesn’t have proper ventilation, you will experience a number of problems. Moisture will accumulate and cause various parts of your roofing system to deteriorate. Excess moisture can cause shingles become warped or loose and possibly slip off. If the water damage extends to the underlayment, wood underneath the roof can warp or buckle. This can lead to structural damage and may extend into the trusses or rafters. If these structures become damaged, they may fail to support the roof. It is extremely important that your roof has ventilation according to code specifications and that the ventilation system is working properly. The best way to ensure that your ventilation system is installed properly is to hire a Minnesota roofing...

Roofing MN | Minnesota Roofing Company If you’ve had hail damage and are considering replacing your shingles, you might want to consider an impact resistant shingle. Impact resistant shingles are slightly more expensive than standard architectural shingles because they’re thicker, heavier and come with longer warranty coverage. Roofing MN – Impact Resistant Shingles Some insurance companies offer premium discounts if you install Class 4 impact resistant shingles, which may offset the added cost of the shingles, and lessen the risk of future roof hail damage. Check with your insurance company for details. However, it is important to note that even though impact-resistant shingles can lessen the risk of hail damage, most manufacturer warranties do not cover hail damage even for shingles that pass the UL test. Select a Roof Cover For Your Home That Will Perform Better in High Winds and Hail Storms Underwriters Laboratories (UL) has the most demanding standard for testing the impact resistance of shingles. The test determines the amount of stress a newly manufactured shingle can withstand without cracking. Here’s how it works: Steel balls of various sizes are used to simulate the force of free-falling hailstones. The steel balls are usually dropped from 20 feet. The steel ball hits the shingle at 90mph and comes to an instant stop. This is a higher force than most hail that hits a roof. The shingles are struck twice in the same spot to test impact resistance. A rating is assigned to each shingle (Class 1, 2, 3, or 4) to signify resistance to a particular size steel ball; the higher the rating, the greater the impact...

What Type Of Material Is Best For Your Home Roof Comparisons There are many types of roofing materials—some of which are brand new with a range of pluses and negatives.  You can re-roof with the same type of roofing material that you currently have or investigate alternatives.  Some materials are environmentally friendly and some are long lasting or low maintenance.  And who doesn’t love low maintenance? Are You Thinking About A New Roof? Wondering what type of material might be best for your home? Before making your choice, consider the life-cycle cost of your roofing material.  Some materials, though much more expensive, require less maintenance and have a longer life expectancy than others.  An asphalt composition roof might last just 20 years whereas a metal roof might last more than 50.  Consider both the current and potential value of your home, and its age when calculating whether a roofing material is actually “too expensive.”  It might just be more cost-effective in the long run. The following table describes some of the roofing choices available. Roof Type House Style (Advantages and Disadvantages) Composition (asphalt shingles) Can be used on any house from contemporary to historic.  False thatched roof with the wrapped roof edge on 1920s Tudor style. inexpensive ranges from low-cost 3-tab shingle to architectural shingles with extra durability and style many colors, types, and manufacturers suitable for most residential applications easy to repair fire resistant relatively short life-span (15–30 years) scars easily when hot subject to mildew and moss environmentally unfriendly Wood shingles or shakes Bungalows, ranch, contemporary, cottage, historic natural look weathering to a soft grey offers some insulation...

Minnesota Roofing Minneapolis MN Between 1991 and 1995, wind and hail resulted in an average of $8 billion in insurance payouts each year, and wind and hail damage to roofs comprises a significant portion of this cost. Hail damage to asphalt shingles may include severe granule loss, material loss at shingle edges, and penetration. Wind can also create serious roof damage-it is documented that roof material failure was the most widespread type of damage from Hurricane Hugo (Manning, Billy R. and Gary G. Nichols. 1991. “Hugo Lessons Learned.” In Hurricane Hugo One Year Later, Benjamin A. Sill and Peter R. Sparks, Editors. New York: American Society of Civil Engineers). High Wind- and Impact-Resistant Asphalt Roofing Shingles New shingle products are designed to resist damage from impact and high winds. They meet the most stringent standards for impact resistance (Class 4) set by Underwriters Laboratories (UL), and wind resistance set by UL and the American Society for Testing and Materials (ASTM International). Several manufacturers offer asphalt shingles designed to resist the effects of severe weather such as wind and impact from flying debris or hail. Different proprietary methods are used to keep granules attached to the shingle, to prevent shingle breaking during impact, and to keep shingles attached to the sheathing during high winds. UL 2218 classifies the resistance of roofing products to impact damage. In the test, steel balls are directed at roof samples, and damage is observed. Products that receive a Class 4 rating from UL 2218 are the most resistive to hail damage. Some major insurance companies are offering homeowner premium discounts for the use of roofing...

Minnesota Roofing Contractor | The Impact Resistant Roof

Emerging Research and Impact-Resistant Roofing Minnesotans are no stranger to severe weather. Whether it’s snow, hail, rain, or wind, our roofs take a beating. After a brutal winter, we are now entering the rain and storm season, which means hail and tornadoes. Hail is a peril that threatens all but a handful of states in the United States, but it doesn’t strike all areas equally. Since 1980, the country has averaged 3,000 hailstorms a year.  Officials estimate that up to 40 percent of all homeowners insurance claims result from hail damage. While the Midwest and Great Plains states have the most hailstorms, Colorado has the most storms with large-size hail (diameter greater than 1.5 inches). So even though Colorado has fewer storms, the storms that occur cause more damage. Impact Resistant Roofing Lost in these large numbers is the number of repeat claims — resulting in payments to the same customers for the same type of repairs from the same type of hailstorms. There are some areas of the nation’s hail belt where homes have been reshingled two and three times during a 10-year period. While a hailstorm usually strikes a relatively limited geographical area, there are parts of Texas, Oklahoma, Kansas and Nebraska where hailstorms average six strikes a year or more. Clearly, the same houses are exposed to these storms. They are likely to receive damage. As a result, home insurance coverage in these regions has become expensive. As premiums rise, both insurers and their policyholders become concerned. To help combat rising premiums, insurance companies look for ways to prevent future damage. They also look for ways...
