Do any of the existing shingles on your roof need to be removed and replaced? Consider the age of the existing shingles and the condition of the roof. If the roof is in good condition and is facing the right direction, it may be possible to reuse or recycle the shingles. If you're looking at an entire roof, for example a roof on a building you purchased and are now renting, it may be more feasible to install a completely new roof. Replacing the roof on a rental property will net a smaller profit, but it's a good decision for a secure future and financial security for the generator.
To avoid purchasing new shingles where you don't need to, consider matching shingles to the existing ones you already have and then re-shingling the roof. It will help if you keep the current shingles on your roof to maintain the appearance of your home. Any additions or upgrades to the shingles should be based on your physical needs and budget constraints. The most important factor to understand is that both new roofing and repairs to your existing roof will add value to your home.
When contemplating a new roof, consider an architect to aid your design in making the most of your roof's features. Your architect should be experienced in roof design. Create a budget; a realistic budget of what your expectations are, and any home modifications that may be needed. Determine your estimated costs. Are you planning to build a deck around the house? If so, how much will it cost? Perhaps you will add skylights, a fireplace or illumination fixtures? Research the cost for the materials needed (and require an estimate for each). Then, an experienced and knowledgeable contractor should come in and assess the cost. Doing so will enable you to add the correct amount to the roof and remain within any budget constraints.
Once next in your list of things to consider is the project timeline, which is as important for your own comfort and making your dollars work. Compare the forecasts for the weather for the time to come for each potential project option. It's ideal to establish a building timetable that's permanent, not task-oriented, so you'll be able to follow it without constant changes. Importantly, traffic requirements, work flow, and parking will affect the timetable. Once are sure you can provide the necessary access and parking for construction.
Looking at weather forecasts, plan for tackling any potential weather issues. If your roof is in a climate that is prone to extreme weather, you'll need an additional weatherproofing material. Don't forget your seasonal and light-house requirements. Inspect your roof and gutter system to ensure the roof and outdoor drainage is in good working order and compact. Talk with your contractor about installation during the cool months to keep the temperature of your home moderate. Determine your air conditioning and heating requirements and obtain a new roof that will best compliment your home.
Once a roof is decided upon, consider the design of your home and its direction. Will there be any shading during the hottest days of the year? Will the sun beat down on the home south facing windows? And, does the house face the slope of your new roof? Have you made a minor modification to the original roof and are your current energy bills to accommodate it? Do you live in a strategically placed shade tree to shield the heat of the sun during the same time?
All these decisions will go into the calculations of the "cost of a new roof" for the design of your home. Obviously, the final decision is yours. But discuss all the options with your architect, especially depending on what you intend to use them for. The best roof is one that fits your lifestyle.
