Flat roof systems work by providing a waterproof membrane over a building. While they do require routine maintenance, flat roofs provide some distinct advantages over the use of a traditional pitched roof:

• Flexibility of design
• Ease of installation
• Cost savings
• Low maintenance
• Opportunities for recreational/decorative finishes

Modified Bitumen
A modified bitumen roofing system uses polymer-modified bitumen (asphalt) reinforced with polyester, fiberglass, or a combination of both. The bitumen determines the membrane's physical characteristics and provides primary waterproofing protection while the reinforcement adds strength, puncture resistance, and overall system integrity. The two most common modifiers are APP (atactic polypropylene) and SBS (styrene-butadiene-styrene). APP was added to asphalt to enhance aging characteristics and was applied to polyester, fiberglass, or polyester and fiberglass membranes to form a sheet good, cut in manageable lengths for handling. SBS is used as a modifier for enhancing substandard asphalt and provides a degree of flexibility much like rubber. It also is applied to a myriad of carriers and produced as a sheet-good in rolls that can be easily handled.

EPDM
EPDM is an elastomeric polymer synthesized from Ethylene, Propylene and a small amount of Diene Monomer. It is the most common flexible roof membrane in use today. One of the most important features a roofing material must possess is the ability to retain its physical characteristics during its service life. EPDM is highly flexible, making it able to accommodate temperature changes and structural expansion/contraction. EPDM roof membranes can be installed fully adhered, mechanically attached (using batten bars), or ballasted. Most EPDM membranes do not receive surfacings. EPDM roofing can be a cleaner, cooler and generally easier product to handle than the built-up roofs (hot tar or asphalt) of yesteryear.

TPO
Thermoplastic Polyolefin (TPO) can be fully adhered, mechanically fastened, or ballasted. It is available in a variety of colors including white, which reflects sunlight and reduces energy bills. TPO roofing is easy to repair. Each TPO membrane is single-ply, flexible, and durable. The seams are weldable with hot air. The membranes have excellent ozone resistance, are algae-resistant, are long-lasting, and environmentally sound. A TPO membrane roof resists tears, punctures, and impact damage. The flexibility also allows for building movement and settling. TPO seam strengths are reported to be three to four times higher than EPDM roofing systems.

Elastomeric Roofing
Elastomeric roof coating is an acrylic latex spray-on product that has several different uses in roofing systems. It is typically white, which reduces heat buildup and energy costs. It can last up to 20 to 50 years if properly applied. Elastomeric coatings applied to metal roofing systems significantly reduces their surface temperature. The coating can reflect 80 percent of heat and ultraviolet rays from the sun. It also has the added benefit of extending the roof's lifespan due to its ability to reduce the heat stress on the roof structure. Elastomeric coating remains flexible below freezing, resists hail damage, is flame retardant, and has excellent adhesion to different roofing products.

  "The owner is a pleasure to work with. He is very professional and explains everything that will be done. The crew went around the house and moved anything away so nothing was damaged. Afterward they cleaned up as if they were never there. All nails were picked up, everything was put back in place. A couple of months later we had a leak in our bedroom ceiling. David came out right away, found the problem had nothing to do with our new roof, it was a vent pipe that opened up, and fixed the issue for us even though it was not related to our roof. We highly recommend AAA Better Roofing."

  "Dave Lancaster and his company's crew were the most professional construction crew I have had at my house! Dave worked with me and my insurance company, even taking time to meet directly with the adjusters on my behalf. My roof was completely torn off and replaced in two days. The speed did not spare excellence of work. Dave has a very large crew. The workers were so nice that they even helped Grandma in with her groceries. Everything was meticulously cleaned up at the end of each day. The roof is gorgeous and sound! Thank you Dave!"

Dave was quick to return my call for an estimate, showed up right away & gave a very competitive price & was very easy to work with. I highly recommend them."

He is responsible, does what he promises, and is organized. He was extremely thorough and inspires great confidence and trust. We feel very secure about our roof now that Dave and his team inspected and repaired it."

  "David and his crew far exceeded my expectations for professionalism, honesty, incredible hard work by all, attention to details, and outstanding work. Each time I look at my new roof and large new balcony, I am thrilled that the expense was reasonable for the project, that it looks gorgeous, and I know everything was done correctly and with great care. David was on site daily (7 days!) and communicated continually. I recommend AAA Better Roof with no reservations whatsoever."

  "I received bids from 4 companies. AAA Better Roof's owner, David Lancaster, personally interacted with me throughout the entire process and could not have been more accessible or easy to work with. He addressed all of my questions and concerns promptly. I was impressed with the comprehensiveness of the inspection and detailed proposal. The quality and attention to detail of their work far exceeded my expectations and the roof looks fantastic! I highly recommend AAA Better Roof. David and his crew are responsive, professional and in my opinion, without equal in the area."

  "Done in 1 day. A whole team (approx 12 people) came in with dumpster, removed both layers of roofing, added new roof vents and properly vented the 2 bathroom exhaust fans, checked and cleaned gutters. Very pleased that the noise, mess, and dumpster were there and gone in less than 12 hours. Owner came back to review the work performed by his crew. Very pleased with the work done."

  "Dave and his crew are exactly what you want from a roofing company. After a huge hail storm we had him come out and identify the damage. He met with the insurance rep and helped with our claim. He gave us a quote, we set a date, they worked three days straight until the job was finished. None of this jumping from job to job and dragging the project out. They replaced the roof, some decking, skylights, gutters, downspouts and added ridge vents. He made it a very simple process."

  "I have a very large cedar shingle roof. I requested estimates to repair the roof from 5 roof contractors. One (that I previously used and was happy with) did not show up and never called. Three wanted to only replace the roof for a steep price. Dave Lancaster was willing to replace the bad shingles and do the repairs I needed. I think he did a quality job and would recommend him to others. He was also the only one that actually went on the roof to check it out before he gave me an estimate."

  "We were very pleased with all aspects of the re-roof job from bid process to completion. Dave was very thorough and patient in answering questions so we were able to compare bids from 4 contractors which were all written and outlined differently. AAA Better Roof brought in a large crew. The entire crew was courteous, worked long days, and were meticulous in cleanup. Special care was taken to ensure landscaping was not damaged in the process. We highly recommend AAA for their quality workmanship."

  "I could not be happier with getting our roof replaced by AAA Better Roof. We were trying to sell our house when we found out we needed to replace our roof due to defective shingles and poor installation. Dave was able to squeeze us in the schedule right away since we were in a rush. When I got home in the evening the only evidence they had been there was our nice, new roof. The whole project went smoothly and I was very impressed by the quality of work and the professional, efficient manner in which it was completed. I highly recommend AAA Better Roof."

  "I hired AAA Better Roof to make repairs and upgrades prior to listing my home for sale. The crew showed up on time. They were courteous and delivered quality work. As a result, my buyer's inspector found no issues with the roof."
  Mary B.

  "We are very happy with the service provided by this company. They held their price to the estimate, no extras. There was an extra, Dave the owner went the extra mile to do some extra work at no additional cost. The whole house was done, complete tear off to the last shingle all in one day. The clean up job was immaculate. I would recommend AAA to anybody, thanks Dave."

  "I was told this was the biggest single home roofing job due to the numerous elevations of my roofline. There were at least 14 workers here daily for over one week. I never saw such professionalism and the owner Dave was onsite at least three times a day. At the end of each day, they completely cleaned the debris and made it livable for us. The roof is gorgeous and I highly highly recommend them for anyone who wants the best possible quality and service there is."

  "AAA Better Roof did an outstanding job from estimate to completion. During the project, the team arrived early and stayed late to complete the project before rain moved in to the area. The roof looks and performs great."

  "Cleanup was excellent with people circling the house several times during the day gathering debris and using a magnetic sweeper. They did not cause any trouble for my neighbors, no loud music, no blocking driveways or sidewalks. Workers arrived at the agreed upon time and day; they ended when predicted, in one day. There were no unexpected costs. Due to the vents they added, my house actually has better ventilation then it did before. The house has survived several storms since no problems at all."

  "AAA made replacing the roof and gutters "a piece of cake." The estimate was timely. Dave Lancaster explained very clearly what he recommended and why. He gave me choices and prices. After I selected AAA, a large crew arrived exactly when expected and performed the work quickly, professionally and exceeding expectations. The crew was careful not to damage landscaping and cleaned extremely well, making sure every scrap of old roof or other materials was gone. I was very pleased with AAA."

  "They were prompt, responsive, and did a wonderful job. They were also quick; they provided me with an estimate for the insulation and were then able to start right away. They offered recommendations and were helpful. The experience was great all around, and I would recommend them. With both the roofing job and insulation job, they left the site clean and picked up everything; no damage was done to the landscaping or other property."

  "AAA Better Roof was excellent and the team of 11 was professional, efficient, and did a great job. I watched how they worked together to do the job on time, the right way and completely clean up throughout the 2 days. I'm happy to see the results and appreciate how David Lancaster helped and treated us. They all get the top score!"
