How To Install Roll Roofing?: Guidelines And Procedures

By: John Garcia | Date Posted: September 23, 2021

Do you know how to install roll roofing? Roll roofing is put over exposed wood sheathing as well as sheeting that has been primed. The sheathing would be better protected against dampness and leaks if roofing felt is applied first.

Employ roll roofing as a cost-effective roof solution. Installing this material is simple and just takes basic carpentry abilities.

Choose roll roofing for such a practical alternative when aesthetics isn’t as crucial. It’s built of materials comparable to composite shingles although it’s not as durable.

Verify the guarantee, which may be limited to one year. Should last longer when you construct and how to install roll roofing that uses the double-coverage approach.

You can utilize the exposed-nail technique if the roofing is slanted. Use the shrouded approach for a slightly slanted roof.

Have double coverage on some kind of flat or almost flat roof, while a torch-down thermoplastic polymer or EPDM roof would be a superior option.

Consider spending half a day constructing flashings as well as roll roofing for something like 700-square-foot roofing with minor issues, working with such a helper. Remove the old shingles from the roof and prepare for just a reroof simply ripping them off.

Very basic carpentry qualifications are necessary to install such roofing material because it is the easiest of the roofing components to install.

How To Install Roll Roofing?

Materials to be rolled out

If necessary, install sprinklers, flashings, roofing felt, as well as WSU. Although metal valley bridging can be installed, it is more customary to begin applying an 18-inch-wide band of roll roofing.

Place it on a layer of roofing cement, level out any creases, and then attach it to the edge.

Join the First Course

Place the first course approximately 1/4 inch overhanging the drip edges as well as roll this out a length of 8 feet perhaps once. At one end of the rake, insert nails every 3 inches, draw it taut, as well as drive nails along the exhaust vent edge.

Nails ought to be 1 inch away from the edges. Install a 3-foot-wide border in front of the 18-inch for added protection.

Affix the second sheet

Each following sheet overlaps the previous by 4 inches and, in the case of certain kinds of roll roofing, quite enough to conceal the bare mineral covering the region.

Snap a straight edge indicating the head of the second sheet, and stretch it out towards the line, after which nail it in place as you did with the first.

Pour Roofing Cement on the Roof

Make sure that neither two welded joints are more than 2 feet apart. Apply a 6-inch-wide coating of roofing cement along the first module’s edge, then press the next sheet into the cement.

Vents that are sealed

Apply roofing cement together around the plumbing outlet to seal it. Cut a 2-foot-wide hole in the middle of the roofing as well as slip it across the pipe. Each piece should be at least 4 sizes bigger than the lower course.

Drill a hole inside the roll sheeting and cover it with it. Cement two roofing sections together. Add a startup flashing for extra security.

The Valley Overlap

Build 2 feet beyond the center of a valley through one side roof. Moving from the opposite side, overlapping the valley, draw a chalk outline, then trim the section at the valley’s center.

Keep screws at a minimum of 12 inches from either the valley’s center; for anything closer than 12 inches, have used a 4-inch-wide layer of roofing adhesive.

Place the final piece in place.

Throughout most cases, you may simply overlap roofing sheets at the crest and finish with roofing cement as well as nails.

Wrap the top with a 16-inch-wide piece sunk in cement if indeed the finishing touch does not reach down at some point 8 inches beyond the apex.

Adjust for A Slanted Roof if Desired

If you’ve had a sloped roof, trim 9-inch-wide roofing strips, place them flush only with drip edges along the eave as well as a rake, and secure them using two rows of 3-inch-apart nails.

Apply roofing cement across half some or all of the strips with a trowel.

Next, in the cement, place the first level so that it protrudes by around 1/4 inch. So because roofing is difficult to reposition, place and roll out carefully before pressing this into the concrete.

Just the top edge should be nailed (the part that is bare of mineral coating). Apply a 4- to 6-inch-wide coating of roofing adhesive to the upper portion, then repeat with the subsequent courses.

How To Install Roll Roofing on Just a Low-Slope Roof?

A standard roof comprises three layers: a material layer, a second layer of overlapping shingles, as well as a third layer of shingles.

Rolling roofing is unique. It only has one coat, so it installs quickly and can be done by a homeowner using simple DIY skills and materials. It’s primarily utilized for low-slope roofed garages and outbuildings.

Roll roofing is available in several colors to match the homeowner’s existing roofing. This is either locked down or has a peel-and-stick enduring effect, depending on the manufacturer.

You know how to install roll roofing on your own, and that will go more smoothly if you have a friend to assist you.

Using roofing cement, connect a drip edge to the roof’s edge. Increase the drip edge’s forward edge so that it flows off the rooftop and then into the gutters.

Water may scurry back underneath the roll roofing if the drip edge is not properly installed.

Remove any debris from the roof with something like a broom. Examine for any missing nails or screws inside the sheathing.

These nails as well as screws should be put just below the sheathing’s thickness. Secure the fasteners with a hammer and perhaps a screwdriver, as needed.

Take measurements of any roof troughs and carefully cut off the roll covering to fit. Valleys are troughs that occur when two roof planes intersect. With a knife blade, trim this piece of shingles to that of an 18-inch length.

This roofing material should be placed so that it spans the valley. Small roofing nails placed 6 inches apart while 1 inch in through the roll roofing’s external borders is used to secure the roofing.

Installing Roll Ruffing Process

Overlap a second full-width roller roofing piece on top of the first. Roofer nails, placed 6 inches apart while 1 inch first from the edge, should be used to secure it.

In various places, measure as well as measure 35 inches again from the bottom and sides of the roof covering. Make a chalk line between the marks.

To cover the extent of the roof, stretch out now and cut roll roofing. Set the roofing’s leading layer anywhere along the chalk line.

It should provide you with a 1-inch overhanging overflow, along with the top edge of such drip-edge trimming you put in Step 1.

These bottom edges should be nailed in place first, followed by the sides. Nails should be spaced 6 inches off and 1 inch from either of the edges.

In various places, measure as well as mark 34 inches again from the top of the very first column of roofing. Make a chalk line with your finger. Cut this second piece for roll roofing to fit the height of the roof.

Cover the top of the very first layer of roofing with a 2-inch-wide coating of roofing cement. Its top edge of something like the second column of roofing should align with the horizontal line, as well as the bottom portion should cover the roofing glue.

Nail throughout the bottom border of this column, 6 inches apart while 1 inch from the edge, and secure it. Also, secure the edges with nails.

Install the additional roll roofing rows in about the same manner. Sprinkle roofing cement underneath the top and sides of the roll covering and nail it in place.

  • What You Will Require
  • Ladder
  • Edge with a drip
  • Cement for roofing
  • Broom
  • Screwdriver
  • Measurement tape
  • Knife for everyday use
  • Hammer
  • Nails for roofing
  • Make a chalk line

Final Thoughts

This drip edge, also known as the dripping cap, can be made of either plastic or sheet metal. This not only covers the roof against water seepage, and also protects your fascia and paneling.

To avoid cracking, know how to install roll roofing when the weather is now at least 50 degrees Fahrenheit. In the very same way, apply peel-and-stick roofs.

Just make sure to remove the backing that covers the adhesives on the backside of the roll roofing rather than nailing it down. Apply the glue by rolling a metal roller and over the surface of something like the roofing after it’s in place.

Overlap stitches by 6 inches if you require vertical seams. After nailing gaps in place, use roofing cement to seal them.
