It’s always best to tear the existing roof system down to the structural deck. That way, the new roof system can sit evenly on the deck without any dampness or deficiencies caused by the old roof system affecting your new system.
However, it adds a significant cost to the job in the form of:
Not to mention the noise and disruption a rip can cause. Therefore, building owners typically follow building code requirements, which state that no more than two roofs can be on the building. Therefore, if two roofs exist, we are required to rip the roof down to the structural deck. During our roof design and estimate, we will conduct a core analysis, as shown on the left, which will tell us how many roofs exist in your building. We always patch up the core test opening when we are done.
A single layer of roofing is comprised of:
Two layers of roofing consist of the above, plus another layer of Insulation and Membrane. This is also known as having two roofs. Most roofing work encompasses tearing off existing insulation and membrane down to the structural deck (known as “ripping” the roof), or adding on a second layer of insulation and membrane to the roof system. In some cases, small sections of the structural deck need to be repaired or replaced. The amount and extent of replacement cannot be determined until the existing insulation and membrane are torn off.
You can help protect your roofing investment by following these tips. Our service department is available to perform any of the following rooftop work. We offer simple roof inspections, minor or major roof repairs, and an overall roof maintenance program.
Over 90% of roof leaks come from rooftop units, such as HVAC units. The reason is that flashing these units into the new roof system requires advanced flat roofing experience in the type of system you use. If the installer doesn’t have strong experience, these highly skilled work areas will be the first parts of your roof to show it.
The short answer is, it depends. Some studies have shown that with the amount of insulation we are using on our flat roof systems today, the impact of having a white roof or a black roof is minimal. The same insulation that keeps warm air and cold air inside the building also prevents warm air and cold air from outside the building from getting in. However, the actual impact on your building varies based on who you ask and what study is referred to. One fact is that, once snow falls in New England, you will have a white, snow-covered roof.
Noise always exists when completing roofing work, particularly if your existing roof system is being removed or we are drilling into concrete. While we can’t minimize the amount of noise being generated, we can control when the noise is generated. A popular option we offer is to complete the roof removal work at night when the building is empty.
Unless a 2 part adhesive system is used, there are fasteners in a Fully Adhered roof system since the insulation still needs to be fastened to the structural deck. In fact, since the adhesives rely on the insulation to be secured to the structural deck, fully adhered roof systems actually have more fasteners in them than mechanically attached systems! Typically, 5-8 insulation fasteners are required in a mechanically attached system versus 12-24 insulation fasteners required in a fully adhered roof system.
For any flat roof system, the manufacturer’s warranty is important for a few reasons:
Our family business was founded in 1908, over 100 years ago. That’s quite an accomplishment, considering the average contractor stays in business for only 2 years. Since we were founded in 1908, four generations of Chaffee have owned the company, and four generations have worked at Chaffee, providing excellent commercial and industrial roofing services.
