Frequently Asked Roofing Questions

All too often, roof system problems are discovered after leaking or other serious damage occurs. Periodic (twice-a-year) inspections often can uncover cracked, warped or missing shingles, loose seams and deteriorated flashings, excessive surface granules accumulating in the gutters or downspouts, and other visible signs of roof system problems. Indoors; look for cracked paint, discolored plasterboard and peeling wallpaper as signs of damaged roof areas.

You have two basic options: You can choose a complete replacement of the roof system, involving a tear off of your existing roof system, or re-cover the existing roof system, involving only the installation of a new roof system. If you’ve already had one re-cover installed on your original roof system, check with Preman Roofing.  In many instances, building code requirements allow no more than one roof system re-cover before a complete replacement is necessary.  We can answer your questions and assist you with choosing your new roof system.

Not necessarily. Leaks can result from flashings that have come loose or a section of the roof system being damaged. A complete roof system failure, however, generally is irreversible and can be the result of improper installation or choice of materials or the roof system installation is inappropriate for the home or building.


Most work should not be done yourself. Professional roofing contractors are trained to safely and efficiently repair or replace roof systems. You can damage your roof system by using improper roofing techniques and severely injure yourself by falling off or through the roof.  Preman Roofing has highly trained roof installation specialists and safety is a top priority to our company and our clients.

Maintenance performed by home and building owners should be confined to inspecting roof systems during the fall and spring to check for cracked or curling shingles and cleaning gutters filled with dead leaves and other debris. If you must inspect your roof system yourself, use a firmly braced or tied-off ladder equipped with rubber safety feet. Wear rubber-soled shoes and stay on the ladder (and off the roof system), if possible.  Preman Roofing offers an inspection service if you are uncomfortable or unable to inspect your roof.


Most new roof systems are designed to provide useful service for about 20 years. Some roof system types, such as slate, clay tile and certain metal (e.g., copper) systems, can last longer. Actual roof system life span is determined by a number of factors, including: local climatic and environmental conditions, proper building and roof system design, material quality and suitability, proper application and adequate roof maintenance. Roofing product manufacturers offer a variety of warranties on their products.  Ask about the warranties that come with the materials used by Preman Roofing to see what responsibilities and financial obligations manufacturers will assume if their products fail to reach their expected lives.

The price of a new roof replacement varies widely, depending on such things as the materials selected, the quality of the contractor doing the work, the type of home or building, location of the home or building, and the time of year. To get a good idea of price for your roof replacement from Preman Roofing, call us at:  619-276-1700. Keep in mind that price is only one factor, and it must be balanced with the quality of the materials and workmanship. For each roofing material option, there are different grades and corresponding prices. There also are a variety of styles and shapes. You need to look at the full product range and make a choice based on your budget and needs. Our roof specialists can assist you to choose the right materials for your home and your budget.

When considering your roofing options, the following formula may help: Total Cost (Materials and Labor) ÷ Life Expectancy of Roof System (in years) = Annual Roofing Cost
