How do I know if my roof has problems?

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 problems. Indoors, look for cracked paint, discolored plasterboard, and peeling wallpaper as signs of damaged roof areas.

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

You have two basic options: You can choose a complete replacement of the roof system, involving a tear-off of the old roof, or a re-cover over the existing roof, involving only the installation of a new membrane and surfacing.

San Diego building code requirements only allow one re-cover over your original roof.  A professional roofing contractor will be able to determine if your roof is eligible for a re-cover. Learn more about roof options.

My roof leaks. Do I need to have it completely replaced?

Not necessarily. Leaking can result because some flashings have come loose or a section of the roof system has been damaged. A roof system failure, however, generally is irreversible and results from improper installation or choice of materials or from the installation of a roof system inappropriate for the building.

Can't I just do the work myself?

Most work should not be do-it-yourself. Professional roofing contractors are trained to safely and efficiently repair or replace a roof system. Novices can harm a roof with improper roofing techniques and severely injure themselves by falling off or even through a roof in need of repair or replacement.

Homeowner maintenance should be confined to roof system inspections in the fall and spring to check for cracked or curling shingles and to cleaning rain gutters filled with dead leaves and other debris. If you must see the roof for 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), if possible.

What will a new roof system cost?

The price of a new roof system varies widely, depending on the material selected, the contractor doing the work, the home itself, location of the home or building, local labor rates, time of year, and more. In terms of a ballpark figure though, the average is $8,000 to $12,000.

To get a good idea of the cost for your roof system, get three or four estimates from reputable contractors in your area. Keep in mind that cost 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. Plus, there 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. Pick a contractor who is committed to quality work, like J.P. Witherow Roofing.

How long can I expect my roof system to last?

The condition and lifespan of your roof system will depend on the type of roof system you have, the effects of your local environment, and the maintenance the roof system has received. According to the American Society of Home Inspectors, asphalt shingles generally last 15 to 20 years; wood shingle/shakes, 10 to 40 years; clay/concrete tiles, 20+ years; slate, 30 to 100 years; and metal roofing, 15 to 40+ years.

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 they will assume if their products fail to reach their expected lifetimes.

How can I determine my annual cost?

When mulling over your roofing options, the following formula may help:
Total Cost (materials and labor) ÷ Life Expectancy of Roof (in years) = Annual Cost
