MN Roofing Contractor – Choosing the Right Underlayment

The Importance of Roofing Underlayment We select our roofing material carefully and one of the basics is that it has got to be waterproof. It has to perform that function, so why the heck do we need to spend extra money on underlayment? While the roofing material is indeed waterproof there are other factors that come into the equation. You could quite possibly void your roofing manufacturer’s warranty if you don’t use it. Regulators around the world require it. If you don’t use it you could be in trouble, but the regulations are there for good reason:- The roofing underlayment forms an additional waterproof membrane for the extreme cases that the roofing material itself can’t handle. Extreme wind blown rain, capillary action and ice dams around chimneys etc can let water past the main roofing material. Condensation. In humid conditions variations in temperature between inside the roof space and outside the roof can cause condensation on the inside of roofing material, causing rot in timber dampness and mildew in ceilings. Thermal efficiency. A good underlayment can keep hot air inside the home in winter, saving heating costs and it can keep hot air out of the home in summer saving on air conditioning costs. Choosing the Right Underlayment There are different categories of roof underlayment. The old faithful, roofing felt and its derivatives. Be careful here and check carefully the fire ratings of these materials and your own regulations. Felt itself, as in felt hats is a non woven material. The strands are aligned in a bonding material and pressed into flat layers. The original fibres were probably wool,...

Roofing Contractor MN | Minneapolis Roofing Company

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...

Roof Repair MN | Minnesota Roof Leak Repair

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....

Metal Roofing Contractor Minneapolis MN

Minneapolis Metal Roofing Contractor MN If you live in a humid climate, you’ve probably seen the unsightly black staining that often occurs on an asphalt shingle roof after a few years. Unbeknownst to most homeowners, this common staining phenomenon is caused by airborne algae that collect on the roof and then grow in moist areas, producing roofing stains that look like black streaks. Since asphalt roofing shingles can absorb moisture and stay damp for extended periods of time, they can create a fertile environment for the growth of these algae stains and other microorganisms. Algae, Mildew, and Mold Stain Resistant Roofing Metal roofs are very resistant to algae, mildew, and mold stains for several reasons. First, the smooth, hard surfaces of a metal roof make if difficult for airborne debris, dust, and plant materials to collect. Also, metal roofing materials don’t absorb water, eliminating the damp, fertile, environment that can lead to growth. Finally, metal roofing materials can be thoroughly cleaned without risking damage to the roof. So, in addition to better protection against algae staining, a metal roof is also mold and mildew resistant. Eliminating these unsightly, and sometimes unhealthy mold and mildew stains from your roof will help ensure your home stays beautiful and maintenance-free for many years. Shown here is a typical example of algae staining and discoloration on an asphalt shingle roof. A metal roof is also among the safest of all roofs because of its durability and non-combustibility. Because metal isn’t combustible, metal roofing is fire-rated as Class A. In fact, when wildfires rage through housing developments, often the metal-roofed homes are the only...

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?
