A: The following may indicate that your roof needs replacing:
A: The cost of your roof will depend on its size, shape, slope and the type of material you choose to install. Different roofing materials provide different levels of protection and service life. Also, property insurance might have limitations on replacement roof types.
A: You can install a roof over the top of an existing roof. By doing so, the current owner of the building can save some money on the roofing project. However, installing roofing over another existing roof does not provide the same quality of roof or offer the same level of security that a new roof will.
This is where people say, “Building code, and manufacturers allow it. It must be all right.”
Let’s look how the code officials, and manufacturers look at roof over jobs.
When installing asphalt composite shingles most Building Codes allow for up to 2 layers of asphalt roofing on a structure. The code has nothing to do with shingle performance. It is written in regards to the structural integrity of building, and how much weight it can handle.
Manufacturers also prohibit roofing over an old roof. However if you read the fine print of any roofing manufacturer’s warranty you will find verbiage in their warranty exclusions that say “We will not warrant product failure if roof is installed over a substrate that is not smooth, flat, and clean.” This means that if anything under the roof causes the roof on top to fail, there is no warranty.
Other concerns about roofing over the top of a roof system are:
We believe that roofs should be removed so the property can be totally inspected, and any damage can be repaired before a new roof system is applied. If you are considering re-roofing, and are not sure of what your options are, contact us for your free inspection.
A: On average, a residential roof will take one to two days. The exceptions are roofs that are larger than average, roofs that need extensive structural repairs, or roofs that require specialty materials. Commercial roof replacement time will vary per project. We’ll give you an expected time frame for completion as part of our written proposal.
We arrive on each job site with the manpower, expertise and materials to complete the job in a timely manner. However we will never compromise quality to complete a job more quickly.
A: There is no one roof system that is best for all applications. Keep in mind that even if the best materials are used, the roof can still leak if it is installed improperly. Good workmanship and proper attention to detail are just as important as material selection. Contact us for a flat roof consultation here.
