MN Roofing There are a number of things to consider when selecting a new roof system. Of course, cost and durability head the list, but aesthetics and architectural style are important, too. The right roof system is the one that balances these four considerations. Buying a New Roof – What Are The Options? Asphalt shingles—which possess an overwhelming share of the U.S. residential roofing market—can be reinforced with either organic or fiberglass materials. Although shingles reinforced with organic felts have been around much longer, fiberglass-reinforced products now dominate the market. Organic shingles consist of a cellulose-fiber (i.e., wood) base that is saturated with asphalt and coated with colored mineral granules. To fight fungus growth in warm, wet climates, they are available with special algicide granules. Fiberglass shingles consist of a fiberglass mat, top-and-bottom layers of asphalt, and mineral granules. Typically, a fiberglass mat offers greater durability, but its manufacture is important. The fire resistance of asphalt shingles, like most other roofing materials, is categorized by Underwriters Laboratories Inc. (UL) Class A, B, or C. Class A is the most fire-resistant, while Classes B and C have less fire resistance. Generally, most fiberglass shingles have Class A fire ratings, and most organic shingles have Class C ratings. UL Class A fire ratings are available for certain products that incorporate a factory-applied, fire-resistant treatment. A shingle’s reinforcement will have little effect on its appearance. Both organic and fiberglass products are available in laminated (architectural) grades that offer a textured appearance. Zinc or copper-coated ceramic granules also can be applied to either organic or fiberglass products to protect against algae attack, a...

Roofing Contractors Minneapolis & St Paul MN All roofing systems are made of a number of different components: roof sheathing, underlayment, roofing material, roof intersections, flashing details and ventilation. Each of these systems must be installed correctly for the system to work as designed. Roof underlayment acts as water barrier installed underneath the roofing system. Essentially, it is a roof underneath the roof. It protects your roof from condensation that may form underneath the metal due to the differences in temperatures in the attic and outside. More Information On Felt Roofing Underlayment One of the most common mistakes being made today in the installation of asphalt shingles on new or re-roofing work is the practice of not using felt underlayment.  Many thousands of new homes do not have felt beneath the shingles.  This is a HUGE mistake! Remember, shingles rely on gravity to keep water from entering your house.  It is very possible for wind driven rain to get underneath your shingles or to enter along valleys (especially when the valley shingles have been improperly trimmed!)  Without felt Underlayment, you have no hope of stopping a leak.  With felt, there is a possibility that the water will travel down the felt and not enter your house. Many asphalt shingles that are installed on residential roofs carry a Class A fire rating.  This rating is given to the shingles by independent laboratories.  The ratings are granted only when the shingles are installed as they were tested in laboratory conditions.  The shingles are tested with felt in place under the shingles.  As such, if felt is deleted on your job, the shingles...

Minnesota Roofing Contractor Talks About Roof Flashing

Roof Flashing | Roof Flashing Repair For many people, a roof is something they depend on, but don’t think about. Until, of course, it leaks. If you are dealing with a roof leak, you will most likely hear a contractor talk about flashing.  Roof flashing is usually made from galvanized metal or aluminum and is placed wherever parts of a pitched roof intersect or penetrate. Its purpose is to direct water to run-off down the slope of the roof. Learn More About Roof Flashing Flashing is extra protection for the most vulnerable places on a roof such as where the chimney joins, at the edges of skylights, where dormers meet a roof plane, or any similar seam or joint in a roof design. Flashing is designed to work together with other roofing materials to keep your roof from leaking. Flashing is generally nailed down, but if the flashing is corroded, bent, or missing, it will not work effectively and water can get inside a home and cause serious damage. Why Do You Need Roof Flashing? Roof flashing is a critical part of preventing leaks and water seepage in your roof.  Many contractors view it as the “last line of defense” against water penetration.  Flashing can be made of either galvanized metal or aluminum. Most homeowners choose aluminum because it is easier to bend into the right shape and will not rust.  The principle of using flashing is simple.  Any place on your roof where different surfaces meet – such as dormers, the roof peak, edges, vents, skylights, etc. – requires flashing and proper sealing to prevent leaks from developing...

MN Roof Leak | Roof Leak Repair MN A roof leak can result in significant damage to insulation, walls, ceilings, flooring and personal property. If undetected, a roof leak can cause rot that will endanger the structural integrity of the roof framing system and cause costly repairs.
 The larger the leak, the greater the damage; however, even a pinhole leak can ruin an entire room during a single storm. According to the National Roofing Contractors Association, a roof should be inspected at least twice annually — once in the fall before the rains and again in the late spring to determine how it fared during the winter. Look for loose shingles or shakes, or, if you have a tile or slate roof, check for missing or cracked pieces. On shingle roofs, look for curling, fraying and tears at the edges. Check the flashings around chimneys, vents, skylights and other roof penetrations. They should be tight and in good condition. Maintaining good roof flashings, especially those at roof edges and penetrations, is crucial. Many roof leaks are actually flashing leaks. Sometimes a visual inspection of the roof isn’t enough. A water test may be in order. You’ll need to venture atop the roof to do this effectively. Use a firmly braced or tied-off ladder equipped with rubber safety feet and wear rubber-soled shoes to avoid slipping. Using a garden hose, run water onto the areas where a leak is most likely. For example, if there is a water stain on the ceiling just in front of the fireplace in the living room you’ll want to concentrate on that general area....
