Steep Slope

For most of us the roof is an afterthought — at least until it starts to leak. In addition to keeping the house dry, the roof contributes greatly to the look of the house, so when building a new house, adding on, or re-roofing, it is advantageous to consider all options carefully. When it comes to roof remodeling, there are a number of areas homeowners need to be aware of—from selecting a contractor to the actual start of work of the roof remodeling.

How do I find a professional roofing contractor for my roof remodeling?

Not surprisingly, there are a number of pitfalls to which homeowners can fall victim, including evaluating and hiring a contractor without a personal interview, judging estimates on low price only, selecting products without comparison shopping, and not understanding reroofing basics. We suggest reading our brochure Choosing a Professional Roofer which outlines what questions to ask in evaluating a roofing contractor. You’ll find that being prepared and knowing what to expect when reroofing work begins will help ensure your ultimate satisfaction with your new roof.

Selecting a product

There are several areas to look at when choosing a roofing shingle. To begin, you need to measure your roof. Shingles are priced per square; a square is defined as 100 square feet. Asphalt shingles, which consumers use the most, can cost from $50 to $150 per square. Keep in mind that these costs don't always include the expense of removing the old roof or the labor involved in a professional installation.

The manufacturer’s warranty can range from 20 years to lifetime. The length of the warranty is an indicator of performance and value. The contractors’ guarantee is usually for one to five years on the average. It is also important to determine the contractor’s intent to stand behind his workmanship and to service a valid complaint in a reasonable time period.

Some roof slopes can limit the choice of shingles that can be used. The slope of the roof is measured by the rise versus the run, or the number of inches vertically by the number of feet horizontally. Your roofing contractor will determine your roof slope and guide you to what type of shingle will be best for your roof.

Other factors to consider in roof remodeling

Although you will be hiring a professional roofing contractor to reroof your home, you should familiarize yourself with certain aspects of the reroofing process. There are various conditions about your roof that may limit your product choices or affect the cost of your roofing job. Here’s a list of questions and answers that are relevant to the reroofing process.

1.) Do I need to obtain a permit to install a new roof on my home?

Some local ordinances require permits be obtained prior to the start of roofing work in both new and some re roofing jobs, depending on the locale. If a permit is required, discuss with your contractor who will obtain it and how it will be obtained.

2.) Is it always necessary to tear off existing shingles before re roofing? If they are torn off, who is responsible for the disposal of the old shingles?

There are two options available for re roofing installations. One would be to tear off the old roof before applying the new one (tear off). The second would be to lay new shingles over the existing roof (lay over). While the second choice is the less expensive of the two options, it is not necessarily always the best choice.


There are advantages to tearing off the old roof before installing a new one. For example:

If there are any defects in the roof deck, they will be revealed when the roof is torn off. These defects should be repaired before applying the new roof.

If condensation problems exist in the attic, they too will be revealed when the roof is torn off. Properly designed attic ventilation can then be installed in order to help eliminate such problems.

When the old roof is torn off, waterproofing shingle underlayment can be installed before applying the new roof. This will help protect against leaks created by cyclical ice damage and wind-driven rain.


Tearing off the old roof and starting with a clean deck before re roofing may result in a smoother finished roof system.

Although there is added cost to these advantages, each lessens the likelihood that the validity of the manufacturer’s shingle warranty will be impaired. If the old roof is torn off, your contractor should be responsible for the cleanup and disposal of the old shingles, but make sure your contract states this clearly.

3.) Why is it said that a roof should breathe? How can you determine if the roof is properly ventilated?

When contractors say a roof should breathe, they are usually referring to the ventilation system beneath the roof deck. Most shingle warranties require ventilation. An effective ventilation system will help:


Reduce attic heat buildup

Reduce attic moisture and condensation

Prevent weather infiltration, i.e., drifting snow, wind-driven rain

Prevent ice dam build up


4.) What function does shingle underlayment serve?

Some local building codes and UL standards require that a shingle underlayment (also known as roofing felt) be installed. Also, some manufacturers offer a special water proofing underlayment product (such as CertainTeed’s Winter Guard) which prevents leaks caused by water backup from ice dams—a common condition in many winter snow areas. Protection against ice dams can be obtained by using a waterproofing shingle underlayment at the eaves or lower edges of the roof, in addition to installing adequate ventilation and proper insulation in the attic floor.

A. Asphalt Roofing Systems... It's no secret asphalt looks great on your roof. But asphalt roofing looks even better when you stack it up against the competition! Metal, tile, slate, and wood. None of these materials can match the wide array of benefits only asphalt roofing provides. Whether it's superb colors and beautiful styles you're looking for, or unparalleled durability and performance, the bottom line is you simply won't find all these features in a single material... unless it's asphalt.

B. Cool Roof Coatings... Traditional dark roofs absorb UV rays from the sun and can get surface temperatures up to 160 degrees or higher on a hot day. Underneath, the building heats up, causing the cooling system to work harder and become less efficient. The use of white membranes or coatings has been proven to reduce this effect. The Cool Roof Rating Council (CRRC) measures cool roofs on two aspects: reflectivity and emissivity. They combine to form an overall measure, the Solar Reflective Index (SRI), with cool roofing systems having a positive effect on SRI.

C. Daylighting. . . Interior lighting makes up 33% of a business’ energy costs. But a daylighting system—skylights or light pipes integrated with an energy efficient lighting retrofit/upgrade—can cut down on or even eliminate the need for electric lights during daylight hours, saving thousands on energy costs and earning additional LEED points.


It takes skilled roofing professionals to perform a daylight system installation and to ensure the roof penetrations are properly sealed. If not installed by an expert, your roof may not remain watertight or its warranty could become voided.

Naples Roofing partners with leading manufacturers of daylighting equipment. Together, we ensure that your roof remains secure and you get the most efficient system possible.

In addition to energy savings, daylighting systems are proven to improve productivity in a range of facilities—from improving test scores in schools, increasing sales in retail environments and improved productivity in manufacturing environments.


The roofing and daylighting experts at Naples Roofing provide consultation, system design, installation and ongoing maintenance to help you get the most out of your investment and keep your roof durable and effective.

Benefits of Daylighting

Reduce energy costs – Cut down or even eliminate the need for electric lights during the day.
