How Does The Roofing Process Work?

If your roof is looking a little shabby you're probably considering getting a new one. It can seem overwhelming but when you break down the process it will give you a better understanding of how it works. A roof system is designed to shed water and protect your home. It takes the right materials and quality workmanship to build a roof that is durable and leak proof.

The process starts with a deck made of plywood, sheathing or 1x6 boards. Any wood that is not sound must be removed and replaced before you begin. Next comes asphalt backed plastic membrane that stops leaks at the eaves followed by asphalt paper, the drip edge, shingles and hip and ridge caps. All of these combined protect your roof from water.

Budget Estimate

Whether you hire a contractor or do it yourself, you first want to measure the roof and estimate the materials. To calculate the roof area, divide the total area into rectangles and squares. You can add another 10% to hire a roofer to install a simple roof and 15% for roofs that have hips and valleys. Shingles are sold by the square which is 100 square feet. 80 shingles will cover one square. You'll also need 4 nails per shingle, more for high wind areas which are sold by the pound. Asphalt roofing paper and eaves membrane are sold by the roll and measured in lineal feet. Valleys typically require 16 inch wide flashing, while dormers and sidewall junctions use 6x6 or 8x8 inch square of step flashing per course of shingles. Extra shingles need to be added for hip and ridge caps along with drip edge and ridge vent. Minus labor this gives you a good idea of what your roof will cost.


Once the deck is well fastened, you'll need to prep for roofing. Shingles will be placed in layers to overlap and keep the water out. The drip edge is nailed along the perimeter of the roof first. Next apply an ice and water barrier membrane to overlap the drip edge. The asphalt roofing paper then covers the whole deck followed by metal flashing in the valleys followed by the shingles. Finally caps for the hips and ridges made with folded pieces of shingles are applied.

For a clean look, layout your courses before you begin to shingle. Use a chalk line to mark straight lines for your courses all the way up the roof. Measure one shingle's width up the roof at each gable end the snap a line to join them and proceed up the roof, snapping lines every 5 inches. This allows you to set the top edge of each shingle to the line as you go up the roof and maintain a 5-inch shingle reveal all the way. Vertical lines spaced every 3 or 6 feet also help you to keep your tabs lined up. Start your first course with the shingle edge flush with the drip edge. As you step your courses up the roof, follow the chalk lines to make sure you are maintaining a nice, straight pattern.

Ensuring Performance

There are several details that impact the look and performance of your roof. Shingling the valleys properly and providing adequate flashing and water shedding detail is a must. Depending on where you live and how much rain or snow precipitates, side walls may need higher flashing or extra membrane protection. Chimneys, vents and skylights must be flashed and counterflashed to keep water out. Shingle courses must be cut on an angle along roof hips. Ridges and hips must be capped to prevent water from entering where 2 courses or adjacent roof angles meet. Adding ridge vents allows the roof to breathe in warmer climates. Local codes will help you to know how much roof venting you need.

A qualified professional roofer may be the way to go if you don't have the extra time to do it yourself. This will speed up the completion time if you're a novice since there is no learning curve for them. Experience can help you make sure your roof is done in a timely manner and that it meets high performance standards to protect your home from water damage.

What Determines The Cost Of A Roofing Project?

You know it's time to replace your roof but maybe you're not sure if it will break the bank or not. The best approach to finding out is to calculate the cost before you decide. Multiple factors will impact the bottom line. Figure out how much of the roof needs replacing first. Maybe it's more feasible to focus on the most worn out or damaged areas. Also, how hard is it to access your roof area? What are typical roof costs for your area? Once you know the answer to these questions you can narrow down the cost.

Generally to estimate cost, you multiply the square footage of the roof by the cost per square foot of your roof type. Also price out the materials you want to use. There are more eco-friendly options to choose from now which may cost a little more up front but save you loads of energy in the long run. After you've identified the type of roof you want make sure to discuss this information with your contractor to negotiate the complexity of the job prior to determining the final price. Follow these additional steps to arrive at an estimated cost for the job:

1) Identify the area of the roof to be replaced. Typically the full roof is half again the size of your home so if you have a 1,500 square foot home you can assume the roof is about 2,250 square feet.

2) Determine the pitch of your roof. The steeper the roof, the more expensive the replacement since the contractor will need to use special equipment to access the roof.

3) Will your roofing contractor remove your current roof? If so, calculate the extra labor costs associated with the process and disposal of the existing materials.

4) Price out different options of materials until you are ready to choose the one you want. Discuss the pros and cons of these options with a professional. If it's something like a terra cotta tiling you may need to figure in extra costs to hire a specialty expert.

Once you've come up with a ballpark number, then you can decide what you most need in a roof and then what special needs you are willing to spend more money on if your budget allows.

What Are The Differences Between Commercial and Residential Roofs?

Commercial and residential roofs are not created equal. It's important to understand the key differences between the two to ensure the most feasible option for a building. The area or region in which the building resides plays a large part in the process of roofing. Some of the differences in commercial and residential roofing may call for distinctive mitigation measures related to region-specific perils. Because a commercial roof is a major investment, it is recommended that business owners work with experienced contractors to ensure the designer and building owner are aware of all appropriate perils and utilize cost-effective mitigation techniques.

There is a wider variety of materials available for commercial buildings. The choice of materials may depend on occupancy, cost, slope of the roof and typical weather conditions in the area where the building is located. Commercial roofs are commonly flat or low slope and larger than residential roofs. Flat roofs frequently are unable to be repaired and sometimes require replacement of a significant portion of the roof in order to maintain the integrity of the materials and installation process. Regular inspection and maintenance is highly recommended.

To add to the complexity of a commercial roof, it requires a more specialized design to address snow, ice and equipment. A specialized roofing contractor is required to install, maintain and repair a commercial roof as well. Often extra manpower, special tools and equipment may be required to complete a commercial project.
