Three Shingle Installation Mistakes That Cause Major Problems

By following installation guidelines, contractors can produce a more professional-looking roof that will be far less likely to experience problems a year, two years, or even 10 years down the road.

A roof that isn’t installed precisely the way it was intended can be both unattractive and incapable of standing up to extreme weather conditions. On a laminate shingle roof, overlooking seemingly small details, such as shingle alignment and nailing, can lead to serious problems. Here are some of the most common details that, when improperly executed, can have negative consequences later in the installation or after completion of the roof:

  1. No Starter Shingles/Improper Alignment of Shingles at Eave and Rake

CORRECT: This photo shows the starter shingle being installed correctly. Proper alignment is crucial when installing the starter shingles. Photos: Atlas Roofing

The starter shingle’s two purposes are water protection and wind protection at the eave and rake. A starter shingle is used to seal with the field shingle at the first course along the eave and rake. This helps prevent wind and water from getting beneath the shingle in this critical location. The underlayment is a secondary water barrier if any moisture gets beneath the shingles.

Starter shingles are installed so they overhang the edge of the eaves slightly to allow for water runoff. Then a course of shingles is installed on top of the starter shingles, forming a front line of defense for blow-offs and water damage.

INCORRECT: When starter shingles are not installed, water channels can form where the shingles align across the first course. Photos: Atlas Roofing

When roofers don’t use starter shingles and install the first course of shingles directly onto the eave or rake, water channels can form where the shingles align across the first course. Moisture can then come into direct contact with the roof deck. Shingles farther up the roof are protected by the courses beneath them, which catch and divert any water that happens to drip between the edges. The first course of shingles needs the same defense from the elements.

Tip: Proper alignment is important when installing both the starter shingles and the first course of shingles. If the starter shingles are not secured correctly at the eave or rake, and the first course of shingles is not nailed down evenly across the top of the starter shingles, the roof may be at risk for wind and/or water damage.

Manufacturer’s guidelines for the proper overhang spacing at the drip edge or rake should be followed precisely. If the starter shingle overhangs the eave too much, a gust of strong wind may lift the shingles and cause a blow-off.

  1. Improper Nailing

The obvious purpose of proper nailing is to ensure that shingles stay in place and don’t cause leaks. Local building

INCORRECT: Nail heads should be flush with the top of the shingle. All three of the nails in this photo are incorrectly installed. The nail on the left is over-driven, the middle nail is at the wrong angle, and the one on the right is under-driven. Photos: Atlas Roofing

codes and manufacturers’ instructions give roofing contractors the directions they need to fasten the shingles properly to the roof deck. Guidelines specify the number of nails per shingle and where the nails should be placed.

In laminate shingles, the nailing zone is referred to as the “common bond” area of the shingle. The “common bond” area includes the double-layer portion of the shingle down to the exposure and constitutes the proper nailing area as identified in laminate shingle installation instructions. The “common bond” nailing area must be targeted correctly in order to obtain the proper wind performance as advertised by the shingle manufacturer. Properly

INCORRECT: The nailing area must be targeted correctly in order to obtain the proper wind performance. In this photo, nails are improperly placed both above and below the common bond area. Photos: Atlas Roofing

placed nails go through two layers of shingles – penetrating through the previous shingle course underneath – attaching them securely to the roof deck. Nails placed outside the common bond area can void the roof’s warranty and prevent asphalt shingles from performing as intended during extreme weather.

Tip: Pneumatic nail guns are popular among many roofers. The pressure on the gun should be set correctly before use. Nail heads should be flush with the top of the shingle. If the pressure is set too high, the gun will overdrive the shingle, causing it to sink into the mat. Too low, and nails will be under-driven, meaning they will stick out above the top of the shingle. Incorrect pressure can also cause nails to be driven in diagonally.

Wind and wind-driven rain can lift improperly nailed shingles and cause water damage to the roof and possibly blow-offs. Using either too many or not enough nails can weaken the shingle’s performance, which can also result in blow-offs.

Finally, roofers who prefer hammers should be skilled enough to drive nails consistently into shingles at the right angle, not over- or under-drive them.

  1. Improper Shingle Alignment

Roof shingles are intended to be precisely aligned, both vertically and horizontally. Roofers lay out each course of

INCORRECT: Proper alignment of the shingles is crucial. In this photo, the top shingle has been placed too high. Photos: Atlas Roofing

shingles in a staggered, stepped pattern (think of a brick wall). The shingle edges of one course must be offset from the shingles below. Edges lined up with each other would allow water to seep through to the roof deck.

INCORRECT: The shingle at the top of this photo has been placed too low. Photos: Atlas Roofing

Installing shingles too high or too low compared to the previous course can affect the exposure, which in turn would affect the aesthetics, wind performance and seal strength of the roof. An improperly aligned shingle course would be very noticeable and have a wavy appearance that is unattractive and amateurish.

Tip: Manufacturer’s instructions for proper shingle alignment are printed on the shingle wrapper.

Eliminating Problems Pays Big Dividends

Roofers who are careful to avoid these mistakes can avoid unintended problems after installation. Using a starter shingle at the eaves and rakes can ensure that the installation is off to a good start. Paying attention to proper nailing and nail placement within the common bond area on all courses all the way up to the ridge can optimize the roof’s performance against wind and rain. Finally, carefully aligning each course of shingles both vertically and horizontally will give the finished roof a professional appearance and help to improve the homeowner’s curb appeal.

Challenging Wintertime Installation Completed on Tight Schedule

The Chicago Premium Outlets 250,000-square-foot expansion includes 30 new or expanded stores, two new restaurants, 2,200 additional parking spaces, public art, outdoor fireplaces and a large pond. According to Mike Reynolds, senior project manager for Olsson Roofing Company Inc., headquartered in Aurora, Illinois, “Chicago Premium Outlets is more of a pedestrian mall since the expansion.”

Located approximately 40 minutes from downtown Chicago, the complex now features more than 170 stores including Adidas, Coach, Nike, kate spade new york, Movado Company Store, Saks Fifth Avenue Off 5th, Tommy Hilfiger, Vera Bradley, and Restoration Hardware. The reflecting pond is an inviting rest stop for shoppers, and it includes a play area and a pier-like pavilion with tables, chairs and umbrellas. To support the expansion, Olsson Roofing Company, the roofing contractor on the project, selected a TPO roofing system manufactured by Johns Manville.

A Challenging Installation

The project team faced two pressing challenges: weather and an aggressive timeline. The roofing-installation time frame fell between January and May, so the majority of the work needed to be completed during the coldest time of year. “We had our work cut out for us,” Reynolds says.

The second challenge was the schedule. “The Olsson Roofing team worked several Saturdays and overtime to get the project finished as quickly as possible,” notes Reynolds. “We even heated the inside of the buildings to melt the snow on the roof and shoveled areas to make room for the product on the roof.”

Olsson Roofing chose to install the roof system using the RhinoBond induction welding attachment system from OMG Roofing Products. “We knew that RhinoBond would contribute to a successful installation of the TPO since we were dealing with below-freezing temperatures for most of the first 90 days,” Reynolds says.

The 60-mil TPO was installed over two layers of ENRGY 3 roof insulation (one layer was 2 inches thick and the 2.5 inches). The majority of the roof surface features white TPO, but some EPDM was also used. “Olsson Roofing also used JM EPDM for the parapet walls since rubber is more flexible and quicker to install in cold weather and on vertical surfaces. They appreciated the ability to mix the systems and keep the project moving forward during cold-weather installation,” says JM sales representative Jason Conley. “With such a tight deadline, it was great to have the versatility of two excellent products — the durable 60-mil JM TPO and the flexibility of the JM EPDM, which provided just the right solution for our customer.”

Contractor Restores the Roof on the Museum Beneath St. Louis’ Historic Gateway Arch

Western Specialty Contractors restored the roof of the Museum of Westward Expansion located beneath the Gateway Arch in St. Louis. This photo shows the protection board being installed prior to adding the leak detection system.

Western Specialty Contractors restored the roof of the Museum of Westward Expansion located beneath the Gateway Arch in St. Louis. This shows the protection board installed prior to adding the leak detection system.

The St. Louis branch of Western Specialty Contractors recently completed a project to restore and waterproof the roof of the Museum of Westward Expansion located beneath the iconic Gateway Arch on the St. Louis Riverfront. The work is part of a multi-phase project, spearheaded by nonprofit organization CityArchRiver Foundation, to expand and renovate the underground museum, plus renovate the grounds surrounding the Arch. The Jefferson National Expansion Memorial, which includes the Gateway Arch, Museum of Westward Expansion and the surrounding park, is maintained by the National Park Service.

Opened to the public in 1976, the Museum of Westward Expansion has undergone very few changes since its grand opening. The size of a football field, the museum features rare Native American Indian artifacts and materials documenting the days of Lewis and Clark and the 19th century pioneers who shaped the history of the American West.

Work on the 100,000-square-foot museum roof project began with removing sod and sandy soil covering the top of the roof and 10-28 inches of Elastizell engineered fill using a bulldozer. Next, the existing waterproof membrane was removed from the structural concrete deck.

After two layers of modified bitumen sheet waterproofing were installed, crews apply a coat of adhesive to adhere the asphaltic protection board.

After two layers of modified bitumen sheet waterproofing were installed, crews apply a coat of adhesive to adhere the asphaltic protection board.

Once the deck was exposed, Western crews went to work identifying and repairing leaks in the existing museum lid that had been present for many years, as the existing waterproofing had exceeded its lifespan. Several methods were used to evaluate the condition of the structural concrete deck, which included a chain-drag sounding along with visually identifying delamination and cracks.

Western crews then installed a two-ply Laurenco modified bitumen sheet waterproofing system covered with WR Meadows PC2 protection board. An electronic leak detection system followed by a permanent leak detection grid system were installed over the protection board. Crews then installed a layer of 1-1/2 inch, 60-psi Dow extruded polystyrene with an additional layer of the protection board and a J-Drain 780 drainage mat.

The next phase of the project involved waterproofing the 42,000-square-foot horizontal lid and the 37,000-square-foot vertical walls of the museum addition. Western’s scope of work in this area included installing a two-ply modified bitumen sheet waterproofing and protection board, as well as an electronic leak detection system, along with two layers of extruded polystyrene. A layer of extruded polystyrene was also installed on the vertical walls, followed by the drainage mat on both the horizontal and vertical walls.

During portions of the project Western crews were working over occupied space, as the museum was largely operational during construction.

Additional waterproofing of the north and south museum entrances encompassed approximately 13,800 square feet, which included approximately 5,000 square feet of deck around each leg of the Arch.

The museum was largely operational during construction, and for much of the project Western crews were working over occupied space. The company sequenced the removal of existing roofing material so that they could remove, clean and install new roofing material daily to keep the museum dry during construction.

Testing was a daily requirement during the waterproofing installation. Western was required to complete a pull test for every 500 square feet and take moisture readings for every 100 square feet. Daily observation reports had to be completed during the waterproofing application, with all testing results and location tests documented along with the weather conditions. Additionally, Western crews took 50 photos daily to document the testing and work area.

Construction on the Arch grounds began in August 2013, while renovations to the museum and visitor center began in April 2015. The multi-phase project is still underway, and the improved underground Museum of Westward Expansion is expected to be finished by summer 2018.
