With the materials we've discussed in the first four chapters, you could build the entire structure – except for finishing the roof and exterior walls (siding). And uniquely-designed new roofing products, paired with siding products from the next chapter, can make a world of difference in your project's final appearance. Of course, the final result depends entirely on what your customers hope to achieve. Do they want to reflect their own personal tastes or just make their home stand out in the neighborhood? Roofing and siding products can make a strong statement, so it's important that your customers choose products that complement each other in design, texture and color. Together, the statement they make should be positive.

In this chapter I'll introduce some roofing products for you to consider. Some of these products may be new to you and others are new to the market. Either way, the important factor to consider before selecting any of these products is their performance record:

• Are they suitable for a particular climate?

• Have they been tested in harsh geographical areas?

• How long have they been on the market?

These are questions you definitely want to research, because roofing and siding materials are exposed to everything nature can throw at them. They've got to be able to withstand the punishment. Check with the manufacturer for a track record of any product you're considering. If possible, get references so you can check out the installed product firsthand, and talk with the customer.

I'm not trying to discourage you from trying these products, but remember that you have to be a savvy professional about any of the products listed in this book. Do your homework before selecting and installing any alternative products. Not only do the manufacturers have to guarantee their products, but you have to guarantee them as well. Callbacks are unpleasant and unprofitable, so choose your products wisely.
