For the do-it-yourself roofer there are some things you should know before starting a large project on your roof. General maintenance, costs, fire-proofing and warranties are a few topics to be aware of. If you're not the do-it yourself type, you may want to consider hiring a contractor.

Ice, debris, sun, and rain can cause damage to your roof. Waiting until a problem develops often leads to expensive repairs. You should inspect your roof in the spring or fall to help prevent cracks, leaks, warping or clogged gutters.

When choosing a commercial roofing material's consider price, durability, appearance, and cost. You should also choose a type of roofing that fits your home's needs and style.

If the job is too large for you to complete by yourself, you may want to hire a professional for gutter replacement, historic restoration, wet glazing, and you may even consider hiring a roofing inspector before starting the project.
