Q: There are many manufacturers of shingles and single ply membranes. Does Andrews Roofing sell all products from all manufacturers and does it recommend products from specific manufacturers?
A: Andrews Roofing can supply products from any manufacturer a customer desires. However, based on our extensive experience with roofing products we recommend the CertainTeed line of asphalt shingles and Firestone line for single ply membranes. We also recommend Ecostar and Enviroshake for synthetic shake.

Q: How can a home owner recognize when a roof system has problems?
A: All too often roof system problems are discovered after leaking or other serious damage occurs. Periodic inspections often can uncover cracked, warped or missing shingles; loose seams in single ply membranes and deteriorated flashings; excessive surface granules accumulating in the gutters or downspouts; and other visible signs of roof system problems. Black streaks on shingle roofs in humid geographic areas are algae that do not damage the roof but can be cleaned for improved appearance. Indoors, look for cracked paint, discolored plasterboard and peeling wallpaper as signs of damaged roof areas.

Q: What are my options if I decide to reroof?
A: 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. Andrews Roofing does not recommend re-covering existing roof systems.

Q: My roof leaks. Do I need to have it replaced completely?
A: 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 generally is irreversible. Such failures are usually the result of improper selection of materials and/or improper installation. When re-roofing, both selection of materials appropriate for the application and installation/workmanship in accordance with manufacturers' specifications are essential.

Q: Can I do the work myself?
A: 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.

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.

Q: How long can I expect my roof system to last?
A: 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, adequate ventilation, material quality and suitability, proper installation and adequate roof maintenance. Note that warranties may vary from 0 to 50 years and, in some cases, lifetime.

Roofing product manufacturers offer a variety of warranties on their products. Take a close look at those warranties to see what responsibilities and financial obligations manufacturers will assume if their products fail to reach their expected lives.

Q: What will a new roof system cost?
A: The price of a new roof system varies widely depending on such things as the size, height and configuration of the roof, the materials selected, contractor doing the work, location, local labor rates and time of year. To get a good idea of price for your roof system, get three or four proposals from reputable contractors in your area. 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 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.

Within the roofing profession there are different levels of expertise and craftsmanship. Insist on a contractor who is committed to quality work. 

Q: How can I determine my annual roofing cost?
A: When considering your roofing options, the following formula may help:

Total Cost (materials & labor) รท by Life Expectancy of Roof System (in years) = Annual Roofing Cost

In most cases a more expensive roof system provides a lower annual roofing cost because it performs better, may require less maintenance and lasts longer.
