Guide To Home Improvement - When You Need a New Roof

The life-span of your roof depends on a number of factors, including the quality of materials that were originally used, the severity of local weather (heat, cold, storms), and whether you've maintained your home over the course of your residence. Shingles wear out over time, as can the roof flashing. An inspection will reveal whether you need a new roof.

If you're evaluating your roof, be aware that shingles wear out faster on south or west-facing sides of your home where direct sun can dry them out. High winds raise shingles and allows rain water to seep through. Moss can rot your shingles, and snow or ice can wedge below them and force cracking. If you see stains on the ceiling inside your house, you have roof problems.

New Roofing for Your House

The first step in considering alternatives is to get your house inspected by a roofing contractor. Inspection should include a thorough examination of the roof covering (tiles, shingles, metal, and all under-layers), rafters, sheathing, and flashing (coverings that prevent leaks). Also ask your contractor to examine the gutters and drains.

The insulation and ventilation systems in your house also play a critical part in longevity and durability of your roof. Have your inspection include a thorough assessment of any attic space, louvers, and ventilation systems. Internal moisture and rafter rot cause serious roof damage.

Roof Replacement Choices

You have some options if a simple repair won't get the job done. First, you can have a new roof installed over the top of your existing one. Be sure your local or state regulations allow for a re-covering project. The other alternative is to have your existing roof torn off and completely replaced.

Costs for a new roof depend on the size of the total roof area and the quality of materials used in the job. One rule in estimating the cost of a new roof for your house is to think in terms of materials and labor, weighing costs against the estimated life expectancy of your new roof. Annual repairs or re-roofing can be expensive. Not keeping up with repairs can be even more so.

Next, consider the plusses and minuses in optional materials. Wood roof shingles are lightweight and attractive, but are susceptible to sun and weather damage. New asphalt shingles can have a 20-year lifespan, but can crack and warp. Tiles are well suited for warm climates but may require reinforced roofs, adding to installation costs. Slate is very durable, but makes for difficult work and is costly to install.

If a roof repair or replacement project is in order, ask your prospective roofing contractors for references, proof of insurance, licensing, bonding, and a written estimate.
