Roof Materials

The Catholic Archdiocese of Birmingham required the cathedral’s new roof system be a historically accurate reproduction of the original in materials, design and craftsmanship. The cathedral’s intricate slate tile patterns incorporated three slate colors and square and deep bevel cut tiles. Six large slate crosses and multiple accent patterns, barely visible on the faded original roof, required exacting measurements prior to tear-off and a high level of precision to recreate and maintain over such a large field and on octagonal steeples.

Because of metal thinning brought on by their advanced age, every copper architectural and functional feature in the existing roof system had to be carefully removed and shipped to Midland Engineering’s South Bend facility to be historically replicated in its metal shop. This included seven ornate crosses (up to 17-feet tall), finials, turret caps and more. There were more than four dozen components, for which no original prints existed, as well as over 500 feet each of custom copper cornices and radius gutters with matching straps. More than 20,000 square feet of 16- and 20-ounce copper was utilized for fabrication of architectural elements and flashing.

Midland Engineering was asked to make improvements to the original roof system to improve attic ventilation while maintaining the Gothic Revival period look. To accomplish this, the crew integrated bronze screen (invisible from the ground) into the original copper cornice and eave design to provide improved cold air intake while new louvered copper dormers replaced the original painted roof ventilator.

An updated lightning protection system was incorporated into the new roof design, hidden within many of the new copper crosses and other architectural elements. The system was fabricated in Midland Engineering’s shop to maintain the Gothic Revival look.

The metal shop also clad 10 previously painted windows and mullions in copper, effectively eliminating frequent and costly maintenance. These windows, reachable only by crane at considerable expense, formerly required painting and other maintenance every five to seven years.

About 6,500 square feet of lead-coated copper, which patinas to a limestone color, was utilized to cap all limestone exposed to weather, reducing ongoing maintenance of limestone joints.

Extensive termite damage to structural framing required repair prior to installation of the new roofing system. Upon removal of the original slate roof and completion of the structural repairs, the new roof was dried-in and installation of the new slate roof began. The historically accurate replacements of the original copper architectural features were installed according to schedule.

Roof Report

The Cathedral of St. Paul is the centerpiece of the Roman Catholic Diocese of Birmingham. Completed in 1893 at a cost of $90,000, the cathedral is widely considered to be a handsome example of the American Neo-Gothic variant of the Gothic Revival style. The cathedral measures 96-feet wide by 140-feet long and encompasses more than 60,000 square feet. It features twin octagonal steeples, rising 183-feet high.

Work schedules on this project were a challenge. The contract required parishioner and clergy access to the church must be maintained 24 hours a day, seven days a week, throughout the eight-month duration of the project. Further, because of the noise inherent in roof construction, work schedules had to be planned around regular church services and events and rescheduled several times a month for funerals and other unscheduled events.

“We could not have been more pleased with the work accomplished by the team from Midland Engineering,” says Very Rev. Kevin M. Bazzel, V.G., J.C.L., rector of the Cathedral of St. Paul. “It is a marvel to us to be able to see the church in its original glory, and all of this thanks to Midland!”

The National Roofing Contractors Association, Rosemont, Ill., awarded Midland Engineering the prestigious Gold Circle Award in 2016. Midland was recognized in the Outstanding Workmanship—Steep-slope Category.

Baker Roofing: 100 Years of ‘Always Good Work’

Baker Roofing Co., a full-service building envelope contractor, was founded in 1915 in Raleigh, N.C., by William Prentiss Baker. At the time of its founding, Baker Roofing employed only a handful of workers at its Davie Street address in downtown Raleigh. Since its founding, the company has grown to become one of Raleigh’s largest employers. In addition, Baker Roofing’s footprint stretches across the Southeast with offices spanning six states and 18 cities. In fact, at the beginning of 2015, it opened offices in Orlando and Jacksonville, Fla.

Whether you ask a new employee or one of the many employees who have been working at Baker Roofing for decades, they will give the same resounding response that Baker Roofing stakes its reputation, growth and business on its 100-year-old promise of “Always Good Work”.

The company continues to be family-owned and operated by W.P. Baker’s grandsons, brothers W. Prentiss Baker III, chairman and co-owner, and Frank Baker, vice chairman and co-owner. Prentiss recollects the company’s founding, “When my grandfather founded the company, he did so with the desire to be the best roofing contractor possible, but I wonder if he ever imagined it would grow into the organization it is today.”

Baker Roofing’s humble, yet confident, beginnings were displayed in its original promise to its clients. Frank Baker describes the foundation for the company’s growth: “When Granddad founded the company, it was during a time in our nation’s history that offered many hurdles for a new business to overcome. Despite this, when he opened the shop, he proudly displayed a sign that’s promise endures to this day: ‘We shall do good work, at a profit if we can, at a loss if we must, but always good work.’”

This year, Baker Roofing celebrates 100 years of upholding the promise W.P. Baker made in 1915. Although the company has grown to employ more than 1,000 people and offer specialty services beyond roofing, like renewable energy and historic renovations, the legacy of “Always Good Work” has never left the DNA of the organization. “As we grow as an organization, the culture of ‘Always Good Work’ continues to drive so much of what we do each and every day,” says Mark Lee, Baker Roofing’s president. “From Nashville, Tenn., to Orlando, Fla., project safety to quality control, multi-megawatt solar systems to residential roof repairs, we will never outgrow or outpace our enduring commitment to the foundation laid 100 years ago.”
