Shingle Roof Replacement

Asphalt and Copper Roof

The great majority of our buildings with sloped roofs are covered with asphalt or fiberglass shingles due to its lightweight and affordability. There is a vast sea of contractors out there today, who maybe gone tomorrow, making all sorts of promises and guarantees. If you are in need of a roof repair or replacement, our Project Managers are available to make an inspection and provide you with our recommendation to help you make the decision, even if it’s not us.

Most residential roofing contractors are enticed to promote a certain manufacturer or brand in order to earn free trips, cash bonuses, and other incentives. Kaller Roofing chooses not to do that. We will recommend the best option for your project, which could include different shingle manufacturers, and price points to help you make the decision. But almost every time Kaller is going to recommend complete removal of the existing roofing shingles. Why? It’s the better job; we repair any damage to the wood roof deck, remove and replace old critically important metal flashing details. No doubt you will hear other advice saying that it’s not necessary, trying to sell you on a cheap price. You will get what you pay for; compare the details in the specifications that you receive. Kaller will always submit for your approval a detailed, written specification and cost proposal.

You are welcome to schedule an appointment at our office to view our the shingle options from all the top shingle manufacturers.

New Tile Roofing

Tile Roof Repair

We have many beautiful, expertly installed old tile roofs in our region near Norristown. The chances are good that your tile is still in excellent condition, but if you are having leaks it’s probably not the tile causing the problem, but some metal flashing elements that have deteriorated and need to be replaced. The tile can last for hundreds of years, the copper or tin used in the flashing has a typical lifespan of fifty to seventy five years. We have eighty years of experience taking these roofs apart, replacing deteriorated metal valleys or chimney flashings and putting the tile roof back together again like nothing ever happened.

Tile is an excellent choice if you are in the design or construction phase of new building. We would be happy to show you some of the projects we have performed from start to finish.

If you have a little copper bay window roof, or a terne coated stainless steel double lock standing seam roof on your museum, we’ve done it! We can help you through the design and material choices to find the right fit for your project. 

No matter what roofing style you decide to choose, Kaller Roofing has the experienced craftsmen in house to properly fabricate and install your metal roof. If you want a truly unique roof that’s durable and beautiful, metal may be the way to go.

Flat Roofing

Flat Roofing Done Right

Flat roofing materials have advanced greatly, some of us are old enough to remember roofing trucks towing a hot tar kettle. Today with the advancement of materials, we have many other types of systems to consider, depending on the project design and parameters. New materials such as EPDM, TPO, PVC, Mod-Bit and others which we can help you understand what’s best for your project.

Flat roofs are critically important to get right, because they are, flat. Water needs to be properly drained. Perhaps you have a ponding condition on your flat roof that requires attention with new tapered roof panels to provide positive pitch towards the drain. Proper flashing details need to be expertly completed at all drainage, side walls, chimneys and any other building elements that intersect the flat roof. So if a problem exists with the adjoining carpentry or masonry that needs repair in the course of the project, Kaller has the in-house manpower to perform the project in its entirety.

International Roofing

International Roofing Contractor

When the U.S. Government performed its nationwide pre-qualification process to select a proven group of roofing contractors with an extensive track record of performing on complex and difficult projects, Kaller was one of the few that met all the qualification requirements. Passing all the Department of Defense (DoD) security background checks, Kaller was provided DoD security clearance to perform roofing projects onsite at some of our most sensitive overseas locations at United States Embassies. The rooftop of an embassy building is the home for the satellite and antenna arrays that are critical to the operation of the embassy, and challenging equipment that needs to be properly built into the roof system. Demanding projects on multiple continents requiring all equipment, tools, materials, personnel to meet strict American specifications all shipped securely from the U.S. and guided through foreign ports per DoD requirements.

Best Norristown Roofer Reviews

Don’t take our word for it – here’s what our clients say:

Kaller Roofing rebuilt our fiberglass roof deck that was leaking in multiple places. They provided expert guidance leading up to the job, and did impeccable work. The crew were very professional, and the owner himself checked in multiple times to assure quality. Our new roof deck is not only more functional, but looks much better and will be a great space for years to come.

Mike O’Hara

Excellent workmanship, high professionalism in the entire crew, especially the foreman, Mike Austin. They were prompt, kept us apprised of the progress, excellent site cleanup at the end of each day, and upon job completion. Beautiful result. Will recommend to others. This is the second time Kaller has roofed our house, our experience 30 years ago brought us back this time.

Rob Nelson

Fine work. A great team. The guys (Rich, Carlos, Jake and Justin) were conscientious, professional and talented. It was a large job from a home owners view and they handled it well with an attention to detail. Hats off to Chuck and Ray also for their supervision and support. This twin is 120 years old and with care like this it can go another 120 years.


Jim Shugart

The roofers explained everything beforehand and were very prompt each day. They appeared to be very knowledgeable. We had a very bad experience with another roofing company and Keller was certainly much more professional and trustworthy. We will definitely use Keller again if we need a roofer.

Ellen Madof

I am the facilities manager of a large church in Greenville, Delaware. Kaller Roofing has been our roofing partner for over five years, and I highly recommend them. Ray Kaller is a skilled and experienced diagnostician, which I think is the most important part of the process of getting to a solution. The members of his team are also highly experienced and easy to work with. Give them a call!

Michael Sayer

Our home’s slate roof and ice damaged gutters were in need of professional help. An exhausting search lead us to Kaller and Sons. Chuck made the whole process painless while Rich and Carlos’s high level craftsmanship along with quality materials yielded amazing results. We couldn’t be happier. Thank you gentlemen.
