Adverse Effects Of Rolled Roofing

Roll roofing installation, Flat roof installation step by step ,must watch!

Rolled roofs are available in very few colors, and the standard one is black. This will be a significant disadvantage if you want a color that matches your structure because it is almost impossible to paint the roof.

The roof has a very short lifespan that you cannot compare to shingles. That is because it cannot freely expand and contract with weather changes, unlike the shingles. Therefore, when exposed to any changes, the roof can easily tear.

The less variety of the roofing material and a few choices of colors makes rolled roofing less attractive. For that reason, some homeowners associations have rules that discourage people from using rolled roofing as a roofing material.

This roof is less durable because it can stay for only five to eight years, compared to shingles that can last for over 20 years. One of the reasons that contribute to this is the inability to contract and expand with weather changes.

House structures with rolled roofs have a low resale value. The roofing material is less durable and can tear when struck or exposed to a lot of pressure, so homebuyers do not like it. The roof is considered a temporary one.

Installing The Rolled Roofing

  • 1 Using a measuring tape, measure 35 inches up from the bottom of the roof and make a mark with chalk. The measurement of 35 inches is the default measurement used by most roofing professionals. Use a ruler or meter stick to draw the chalk line across the roof.XResearch source
  • Avoid using eaves as guides as they are not necessarily placed at the same height across the roof.
  • 2Apply roofing cement to the roof. Use a trowel to scoop up the roofing cement. Spread the roofing cement along the edges of your roof so itâs about 1â8â1â4 inch thick. You can get roofing cement at the local hardware or building supplies store.XResearch source
  • Apply the cement in stages. Do the bottom part of the roof before you start working on that section, apply it to the middle before you start working there, and so on. Use the chalk lines as the borders of each section.
  • Always wear gloves when working with roofing cement.
  • Read the instructions on the side of the roofing cement container before you begin.
  • 3Cut the rolled roofing to the right size using a razor knife. The rolled roofing should reach the chalk line when you lay it down and should stretch from 1 side of the roof to the other. You’ll need to use plenty of pressure with the razor knife to cut the rolled roofing material.XResearch source
  • The first layer should cover the roof as far as the chalk line.
  • Be careful when working with a hammer and nails on a roof. Make sure you have a stable grip on the roof.
  • Mark Your Working Area With The Chalk

    Keep that measuring tape handy because youll need it when you begin the installation process. Keep in mind that rolled roofing is typically installed horizontally.

    Grab your measuring tape and chalk line, measure 35 inches up from the bottom edge of the roof, and mark it with the chalk line. Use a meter stick to ensure your line is straight and even across the roof. You dont want crooked roofing!

    Considerations To Using Rolled Roofing

    One of the biggest considerations in using rolled roofing on your flat roof, besides the material you choose, is the seams. Unless you are covering a small building with a roll wide enough to roll on in one sheet, you will likely have seams between the rows. These seams are a potential weak point for the roof, because they have to be covered and sealed with another material. This may be a type of latex tape, sealant, or tar adhesive. Some materials including rubber, EPDM, and TPO roofing are all subject to expansion and contraction, which means they shrink and grow in heat and cold. The more seams you have, the more areas you have on the roof where the rolls could be pulling away from one another and causing potential leaks.

    Attach The First & Second Sheets

    To begin roofing, you should position the first course accurately so that it overhangs the drip edges and move it out to a calculated distance. Push the nails every 3 inches at one end of the rake, pull it taut, and push the nails further along the eave edge.

    For a good installation, the nail should only be 1 inch from the edges, and for more protection, you could add a 3-foot wide strip on the 18-inches. When placing the second sheet, it should overlap the first by 4 inches, or you could use a different type of roll roofing to cover the area. Use a chalk line to indicate the top of the next sheet then, you can roll it along the line and push nails for the first sheet.
