Installation Tips for Roofing Underlayment Installation Tips for Roofing Underlayment

The roofing underlayment serves as the protective barrier between the shingles and the sheathing. Aside from having several benefits, roofing underlayment might also be a prerequisite for many roof types. Asphalt shingled roofs, for instance, need a tar paper underlayment for covering irregularities and improving the general appearance of the shingles. Leaks and water damage may occur to your house if your roof’s underlayment is improperly installed. Here are additional tips when installing roofing underlayment.

Prepare the Roof before the Installation Process

Unnecessary materials on the roof can hamper the installation process or can pose as a safety hazard. Before you start, be sure to clean the roof and get rid of any nails, loose boards, debris and other unneeded objects. You may also need to reattach or replace some nails on the roof that have come loose.

Do Not Work On Wet Roof Surface

Working on the roof can be hazardous and a wet roof surface increases the risk of falling. Do not attempt to continue the installation project if rain occurs, or if the roof surface is wet. You may resume work only when there is appropriate weather to prevent accidents.

Seek Advice from Roofing Professionals

It is advisable to seek advice from a professional roofing contractor especially when installing specialized underlayment, such as those to be used for extreme weather conditions. Professionals can give you expert advice regarding the best and most durable type of materials to use for the type of weather in your area and which construction option is the most efficient and effective for you.

Have Someone Help You

When using felt or tar paper as underlayment, it is practical to have someone help you in the installation process. This is more convenient and will allow you to finish installing the underlayment faster.

Follow Instructions for Ice and Water Underlayment

For cold climate locations, with winter temperatures falling on an average of below 25 degrees Fahrenheit, ice and water underlayment is essential for protection against ice dams.  Ice barriers in the eaves must extend at least 2 feet over the inner wall, as well as in every rake, valley and roof penetration. Always pay close attention to underlayment specifications and instructions set by manufacturers and conform to local building regulations.

Follow the Instructions for Valleys and Ridges

When installing felt or tar paper, the underlayment should be woven across valleys and, for continuous ridge vents, double lap it across the ridges. Cut the tar paper in an angle so that it can lie down in the center of a valley.

Protect Unfinished Work

If you cannot complete the roofing process in one day, be sure to protect your unfinished work from possible damage that can occur overnight. Rain, wind and other weather elements may wrinkle or tear your roof underlayment. You may cover the unfinished areas with tarp or plastic sheeting.

These tips can help save you from a lot of trouble and roofing problems in the future.
