When it comes time to replace the roof on your home, you need to start the job by evaluating the project from an economic view as well as the practical. Weather and climate can have vastly different effects on different roofing materials and you will need to learn what works best for your area. You must determine if your preferred materials can handle the shape and pitch of your roof and what alternatives are available if not. You must also take a hard look at your finances to honestly determine how big a budget you have to work with.
Look first to the actual structure of your home. Some roofing materials are way too heavy for some types of roofs and the materials used in their construction. If you want to use slate or tile, the support structure must be able to withstand the weight. The pitch is also important. If, for instance, you have a very low-pitched roof. wooden or asphalt shingles would not work as the rain would not run off fast enough to keep it from seeping in under them. Factor in how many chimneys, breaks, dormers, skylights, or other irregularities are on the roof and plan accordingly. A mistake along these lines can easily mean a serious reworking or potentially the collapse of your house under the strain.
Keeping external elements in mind can help streamline the roof replacement process. If there are building or homeowner codes in effect where you live, you may be limited in the materials you can use. Checking to see the prevailing direction of wind, rain, and snow can also play a part in deciding how best to cover your roof. A professional consultation may be best, even if you are a major do it yourself worker and want to complete the project yourself rather than hiring a roofing contractor.
When working up the budget for your roof replacement, you need to factor in not only materials, but labor costs as well. Check your health and accident insurance to make sure you are covered while doing such work. Will building permits cost extra? Will a consulting fee be applied when you seek knowledge from the professionals at the materials supply house? Even if you think you have covered all the bases, it is still best to add on at least a 10% margin to cover fluctuations in materials cost and as yet unforeseen expenses.
