Architects of ultra-modern homes also are fans of flat roofs. Typically, these sections are bordered on one or more sides by parapet walls that have a three-sided metal coping, also known as parapet flashing, fitted atop the walls. Parapet flashing made from sheet metal or copper and fabricated for a particular thickness of wall may be shipped to the job site in sections.

Attaching flashing to a parapet wall requires basic sheet metal tools and knowledge of sheet metal or copper soldering. Roll out bitumen flashing atop the wall from end to end with the self-adhesive backing paper facing down.

Center it atop the wall so each side extends outward in equal amounts.

how to install parapet flashing

Allow the ends of the flashing to extend past the ends of the wall 8 inches. Cut the piece to length with a utility knife. Start at one end and peel the backing from the self-adhesive side. Press the main portion of the flashing into place at the top of the wall as you go. After peeling away the backing, press the sides of the flashing down and against the inner and outer faces of the wall. Measure the length of the wall from end to end.

Cut the sheet metal or copper parapet flashing to length with a miter saw fitted with a metal cutting blade. Cut a degree angle on an end that meets another parapet wall. Otherwise, make a straight cut with the miter saw. Fit the piece of flashing atop the wall so the shorter sides extend down against the inner and outer faces of the wall. For longer walls that require more than one piece of flashing, measure and cut the remaining pieces so each one overlaps the previous by 4 inches.

Lift the flashing off the wall and turn it upside down so the channel faces up. Apply a uniform layer of roofing mastic in the wide channel and both edges of the flashing.

Installing roof to wall flashing

William Machin began work in construction at the age of 15, while still in high school.The majority of roof leaks occur at flashing points. To prevent this water penetration, flashing forms the intersections and terminations of roofing systems and surfaces.

Most professional roofers can easily install a flashing membrane on the flat, open space of a metal roof and then secure it.

But roof lines and profiles are getting more creative and complex. Installers are finding more challenging flashing applications that require more technique and detailed procedures to complete successfully. In a perfect world, a standing seam metal roof would have zero penetrations from the roof eve to the roof ridge. But these long metal field runs used in lateral series are rarely unbroken. On metal roofs, square ducts, skylights, large round pipes, expansion joints, parapet walls, flashing dissimilar roofing materials and profiles all pose challenging flashing applications, says Jim Sharp, president of Deks North America Inc.

All Metal Roofing Specialists feels roofing penetrations such as chimneys and skylights present some of the most challenging flashings on a metal roof. A stone-and-mortar chimney has an uneven surface, and it is difficult to cut into. You want the counter flashing to look good, be watertight and not take away from the appearance of the stone.

We then install a mortar anchor into the joint of the concrete holding the stone. This ensures that our step flashing looks neat and clean. Chimney placement also makes a big difference in how and where we flash. If a chimney is below the ridge line there is water that runs down the metal panels against the back side of the chimney.

Introduction to Wall Coping

Some guys like to build a cricket. We choose instead to counter flash up the back of the chimney, then we will leave the panels about 1 foot from the back of the chimney making sure that we lay the panels out so that the ribs fall to the outside of the chimney.

Water and snow will naturally flow around the chimney. Skylights also present some interesting installation issues. First and foremost, we lay our roofing panels out so that they look symmetrical and so that the panels fall the best way possible behind the skylights.

Our crews like to take the panels and bend them up alongside the skylight. We then will counter flash under the skylight cover and then over the panel. We do this on two sides and the bottom. At the top of the skylight we leave the panels back approximately 1 foot, taper the panels, and install a flashing up under the skylight cover and then under the standing seam panels, which are hooked to a metal z.

All pipe and vent flashings that pass through metal roofs are challenging.A basic introduction to parapet wall coping by professional building envelope consultants. With pictures and useful links for further reading. Also see Edge Metal. What is wall coping? Wall coping is the protective cap or cover on a wall, typically slanted or curved to shed water, protecting the wall from water infiltration from above. Why does a wall need coping? To keep water out of the wall! Water infiltration into a wall can lead to a number of things, none of them good.

When water gets into the interior of a masonry wall and then migrates out through porous masonry such as brick or concrete masonry units, it can lead to unsightly efflorescence. Efflorescence is a commonly seen white discoloration on the outside surface of a wall caused by deposits of natural salts from the wall material.

The salts are absorbed by moisture as it travels through the material and then left behind when the moisture evaporates. Far worse than this is what happens when water within the structure of a wall freezes.

The freeze-thaw cycle is not kind to walls. Pieces of mortar can fall out of the joints, which will let even more water in. The masonry units themselves can become loose. Steel masonry ties and anchors can rust to the point of failure. Wood and steel wall components fare even worse. Long-term exposure to water corrodes steel, and rusted steel can expand up to eight times its original thickness, again with tremendous force.

Wood sheathing absorbs water and swells, delaminates, or falls apart in the case of very cheap OSB. Wood framing members warp and become deformed as they repeatedly absorb moisture and dry out.

This missing piece of coping led to extensive leaking inside the building. Things you should know about wall coping:. Wall coping as roof edge securement: Single-ply roofing membranes commonly run up the inside of the parapet wall and terminate underneath a metal coping.

Shop-fabricated coping should be made by a certified shop. Slope: The top surface of a well-designed parapet wall coping should be slanted or curved to shed water. This reduces the chance that water will enter the wall through open coping joints or leave unsightly stains on the top of the coping as the water evaporates.

Optimally, it should be single-slanted back toward the roof to reduce the amount of water running down the exterior wall of the building, which can cause discoloration. Drip edges: Good copings should have drip edges on each side of the wall.Many apartments and condominiums have flat sections of roof designed for air conditioning or other roof-mounted equipment.

Architects of ultra-modern homes also are fans of flat roofs.
