Re-roofing is the process of recovering or replacing an existing roof covering. Roofing system failures can be caused by a number of factors. Age, severe weather, poor workmanship, defective materials, improper specification of a roofing system failure to maintain the roof are common causes of roofing issues. Sometimes an old or damaged roof can be repaired, restored, or renewed. Re-roofing is the least costly and quickest way to restore the appearance of your roof. During re-roofing, a new shingle overlay is placed over your worn shingles to provide a protective layer as well as restore the look of your roof. This additional layer of shingles acts as a strong barrier from potential damage from the elements, keeping everything under it in a healthy condition. Provided you have just one layer of shingles on your roof, you could be a candidate for re-roofing.

Re-roofing is a great first step if the roof on your home has no underlying damage or missing shingles. While re-roofing is a great option for many homeowners to take advantage of, it is important to know that this service cannot be completed on roofs that have more than one layer of shingles or that have had a re-roofing solution in the past.

Roofing Repairs

A roof repair is any adjustment made to an existing roof, such as fixing leaks, damage, even wear-and-tear. This process should be done by a professional roofing contractor. AMGD Exterior offer’s roofing repairs for Homeowners, Real Estate Agents, and Insurance Adjusters. Roof repairs can be unexpected but are essential in order for the roof to continue protecting the structure of your home and the people in it. It’s not always obvious when a roof needs to be repaired, but our team will complete a thorough roof inspection and offer an honest and professional opinion.

Has a severe storm caused your roof to experience leaks or damage? Ignoring roof issues could cause permanent problems down the road. Roofing repairs from a reputable roofing contractor can prolong the life of your roof, create a better-looking home, and even increase the overall property value. Whether it’s a damaged shingle or severe storm damage, you should have your roof repaired right away.

Uncovered holes in your roof for extended periods of time can ultimately lead to structural damage, increasing repair costs.

Roof Maintenance

Simply put, maintaining your roof will prolong its life. Regular physical inspections of an existing roofing system will determine its current condition, detect weaknesses and failures, and identify any potential problems. Through a program of regularly scheduled annual or semi-annual inspections, AMGD Exterior Contracting will assist the homeowner in protecting their roofing investment. Our technicians seek to identify damage in its early stages, making it possible to repair leaks or failures – which can extend the life of a roofing system and be significantly less expensive and less time-consuming than re-roofing.

I could not have been happier with the level of AMDG’s service and communication. I would recommend them to anybody I know.
