Certified Roof Inspection For New Home Buyers MN

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...

Underlayment Requirements For Minneapolis Minnesota Underlayment is a material placed on the roof sheathing before installing shingles. It is usually a thin, black, paper-like material, often referred to as roofing felt. It comes in a roll and is usually 36” wide. It also comes in different thicknesses or weights. The minimum acceptable underlayment is 15# roofing felt. Underlayment may also be a self-adhering, rubber-like material. This type of underlayment is most often used at the roof edge and in valleys to help minimize damage from ice-dams. Many shingle manufacturers recommend their own type of self-adhering underlayment and where it should be used. Some local building codes and UL standards require that a shingle underlayment be installed. Underlayment shall comply with IRC Section 905.2.3 and its application shall be according to IRC Sections R905.2.7 and R905.2.7.1. Minnesota’s climate is considered severe with respect to underlayment requirements. An ice barrier is required and shall be installed as follows: • The ice barrier shall consist of two layers of underlayment (15# roofing felt) cemented together or a single layer of a self-adhering sheet. Whichever product is used, it must be installed parallel to and extend from the eave edge to a point at least 24 inches inside the exterior wall line. • After installation of the ice barrier, install remaining underlayment as follows: For roof slopes of 2 units vertical in 12 units horizontal (2:12) up to 4 units vertical in 12 units horizontal (4:12), underlayment shall be two layers of 15# felt. Starting at the ice barrier, install the first course of 36 inch wide underlayment lapping the ice barrier a...

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,...

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...
