This is why it is important to get a roof inspection report regularly, both for the inside and outside.

Loose or missing shingles or tiles Loose or exposed nails that can lead to leaks in the roof Dark patches on asphalt shingles or large amounts of granules in the rain gutters Sagging on the ridges or in the center of the roof Broken or loose shingles at the ridge and hip lines Rusty or corroded metal (flashing) and loose shingles in the valleys, plumbing vents or near chimneys Overflowing gutters or excess water pooling near the foundation of your home Blisters, depressions near vent pipes, separations in flashing, and clogged drains on flat roofs (popping blisters with a knife and coating them with roofing cement can prevent further damage; depressions can also be filled with roofing cement).

You Need a Certified Roof Inspection When Buying a New Home – Part 1 Buyers face many dangers when purchasing a home, and there are many different aspects of the home that must be taken into consideration. It is important to get a full survey of the property to see if there are any potential problems before buying the house. Mortgage companies typically demand that some sort of inspection is done on the property in order to be sure you are paying a fair amount, which makes sense considering that this is probably the most important financial investment you will make in your lifetime. Your lender may require that the roof is surveyed as a part of this inspection because they know this is one potentially costly aspect of purchasing a house that is unfortunately often overlooked. Make Sure Your Roof is Safe with a Certified Roof Inspection It doesn’t matter if you are having your roof inspected to satisfy a mortgage lender or if you are doing a routine maintenance check; it’s always preferable to invest in a full, certified roof inspection. When you request a certified roof inspection, a recognized and reputable roofing contractor will come to your house, inspect the roof for any potential problems, and as long as all is well, they will complete the certified roof inspection by presenting you with a certificate. This certificate is typically valid for two years, and if anything goes wrong with your roof in that time the roofing company is obligated to fix it free of charge. Benefits of a Certified Roof Inspection Sometimes it is just reassuring...

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...

Residential Roofing Services MN – Roof Underlayment The correct roofing underlayment, also known as roofing felt is critical to any roofing job. You must use it! Roof underlayment acts as water barrier installed underneath the roofing system. It protects your roof from condensation that may form underneath the metal due to the differences in temperatures in the attic and outside. What Function Does Shingle Underlayment Serve? Underlayments extend the life of a roof by protecting it against leaks. An underlayment, commonly known as roofing felt, will: Protect the roof deck from moisture prior to shingle application Provide a degree of backup protection in the event water gets under roofing shingles. Extend The Life of Your Roof With Roofing Underlayment Some local building codes and UL standards require that a shingle underlayment be installed. Ask your Minnesota roofing contractor if this is the case in your area. Also, some manufacturers offer a special underlayment product which prevents leaks caused by water backup from ice dams—a common condition in our Minnesota winters. Protection against ice dams can be obtained by using a waterproofing shingle underlayment at the eaves or lower edges of the roof, in addition to installing adequate ventilation and proper insulation in the attic floor. (See Prevent Roof Damage From Roof Snow and Ice Dams) Ask your roofing contractor about these specialized underlayments. Underlayment & Ice and Water Protection The entire state of Minnesota requires special eave protection that consist of at least two layers of Underlayment cemented together of a self-adhering polymer modified bitumen sheet, shall be used in lieu of normal Underlayment and extend from the eave’s edge...

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...
