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.

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 have no fire rating.  This may not seem to you to be a big deal; however, it may be a very big deal to your insurance company.  It may be in your policy that they won’t pay a claim if the shingles are not installed or maintained according to manufacturer’s specifications, etc.  I surely would check into this if I were you.
