Q How can a homeowner recognize when a roof system has problems?

All too often, a homeowner discovers a roof system has problems when 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.

Q What are my options if I decide I want to re-roof my house?

You have two basic options. You can choose a complete replacement of the roof system, involving a tear-off of an existing roof system. Or you can re-cover the existing roof system, which involves only the installation of a new roof system. If you’ve already had one re-cover installed on your original roof system, check with a professional roofing contractor. In many instances, building code requirements allow no more than one roof system re-cover before a complete replacement is necessary.

Q Do I need to have my roof replaced completely?

You don’t necessarily to have your roof replaced completely. Leaks can result from flashings that have come loose or a section of the roof system being damaged. A complete roof system failure, however, is generally irreversible and a result of improper installation or choice of materials. Or the roof system installation may be inappropriate for the home or building.

Q Can I do the work myself?

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.
