Effective Roofing Technique

Roofing techniques are not only useful for those who actually put on the roof but also those whose houses are being outfitted with roofs. Outfitters who put this on can sometimes short a homeowner if they think the home owner is not as knowledgeable as they are when it comes to it. There are several layers to a roof and it is important to know these layers in order to have an inkling of how it provides protection to a home. The following common technique is applicable for both new and old roofs and starts with the lowermost layer from the top of the roof in description.


This is the initial layer that basically separates the ceiling from the other roofing layers. In some cases, the sheathing may actually be the ceiling. In other cases, they may be sheets of wood that are attached to the rafters of any roof. For houses with attics, these can be seen in the rafters. These need not be made up of sheets of wood or sheets of plywood; these days, many different materials are used for the sheathing.


This layer of the roofing technique is a necessity which is emphasized by the state law. Usually roofer’s felt is used for this layer but there are various materials available for this as well depending on the needs and preferences of the home owner or the building contractor. The underlayment gives some form of protection for the house against the different elements that may besiege the home that are first met by the roof.

The Roof

The last layer that is usually placed is the roof itself. The home owner also has various styles and materials to choose from for this layer. Metal sheets now come in various patterns and thickness. Some mimic classic patterns such as shingles, while others are more true to the metal roof pattern of bumps or indentations. These are actually quite inexpensive when compared to the other materials used for roofing. The problem with this variety is that they easily rust and may dent, warp or deform when branches fall on them, or if exposed to extreme elements, like hail, snow, and the like.

Asphalt or concrete surfaces may be sturdier than metal but they are also prone to leaks when they are not placed properly. The contractor needs to be familiar with this type of material and have people who are adept at the application. These may be heavier than other varieties and may need a sturdier base to bear the weight. The contractor should be able to see if the house has enough mass to bear the additional weight if it is a reroofing project.

Other materials such as slate and wood are basically the same as asphalt and concrete in terms of application. These need to be placed properly to make them last longer. Wood is prone to plants or moss growth due to its organic composition. These need to be cleared as soon as possible to avoid damage to the wood shingles or the wood slats.

New Innovations in Eco-Friendly Roofing

Increasingly, families across the country are turning to environmentally friendly techniques when re-roofing their homes. Although these methods are typically more expensive that traditional options, that hasn’t stopped them from dramatically going up in popularity. Two of the most popular techniques right now are known as solar roofing and green roofing.

Here are discussed some of the eco-friendly techniques homeowners are using on new projects.

Solar Roofing

Solar roofing is actually something that can easily be done by a lot of homeowners. What many people don’t initially realize, though, that is that there are two kinds of solar roofing techniques.

The first technique people are talking about is a system where the solar panel itself is actually a part of your roof. So there is no roof and solar panel-it is all in one. Unfortunately, the cost of this roofing option is astronomical and cost-prohibitive for most people. The reason it is so expensive is because the system itself is quite intricate, and should something happen to the panel or your roof then the entire system would need to be replaced. So, few people can afford this option at the current time.

Instead, the option that many people are going with is a method of attaching solar panels directly to your current roof. This is the much cheaper option, and it is really done all the time in many parts of the country. When homeowners are looking to get this done, they should be contacting both a solar panel installation company and a traditional roofing contractor. These two companies will then work with each other to devise the right plan for your home based on its size, location, and currently roofing material.

Whether or not these solar panels are cost effective, meanwhile, is another issue. In general, installing solar panels on your roof is not going to be a cost effective option, simply because of the added expenses in terms of maintenance and repair costs. So the solar panels most people install on their homes are not going to pay for themselves anytime soon. However, most people aren’t getting these for purely economical reasons, so that isn’t the only determining factor.

Green Roofing

Another environmentally friendly roofing technique, which is actually more common these days than solar panels, is called green roofing. Green roofing is when people who have flat roofs turn their roofs into a massive planter by growing plant life up there.

As a roofer, you would install certain membranes that encourage plant life to grow, then place the soil and plant multiple layers of trees, grass, and other materials. The soil should be able to hold a variety of natural things thanks to the membranes. Additionally, this is a system that can dramatically increase the insulation on a person’s home-thereby saving money on heating and cooling costs.

Not only on a personal level, but on a global level as well, these homes with green roofs can benefit society. Green roofs can reduce the heat island effect in cities across the county because, from above, they simply look like natural habitats or fields. So the chemical properties of traditional roofs that tend to heat cities and speed global warming are not present in homes with these green, natural roofs.

Unfortunately, few roofing contractors do these types of green roofs at the present time. A select few companies in each large metropolitan city offer these services. However, they are becoming more and more common as green roofs increase in popularity.

Overall, these environmentally friendly roofing systems are growing in popularity each year. While they are certainly not for every homeowner or business owner, thousands of people are highly satisfied with their green roofing systems-and that is a number that is growing all the time.

Flat Roof Construction – The Various Techniques You Can Choose From

Okay, you have decided to play your part in reducing the carbon footprint and preventing global warming. You have chosen to have a large solar panel constructed on your roof so you can make use of solar energy for various lighting and heating purposes. This would not be possible if your house has a sloping roof. Opting for a flat roof construction has a number of benefits, one of which is that it helps you set up a solar panel to harness the natural source of energy.

There are a number of techniques that you can choose from. Let us take a quick look at three of the most preferred techniques which are being used by various people all over the world.

Membrane Roofing

If you are looking for long lasting roofs that are water resistant as well, then membrane roofs is the best choice. This flat roof construction is put up using multiple polyvinyl chloride sheets. The thickness of each sheet used in this construction varied from 30mm to 60mm. You need not install a separate moisture resistant barrier on the roof prior to installing membrane roofing. You can place these membranes directly on the roof along with insulation that can offer thermal resistance. Once the membranes are installed, they are bonded together. You can either use a special sealer that helps the sheets chemically bond with each other or you can heat the seams so they melt into each other, thus holding them in place.

Built up Roofing

Built up roofing is the oldest roofing technique which is the most preferred technique in the United States. Moisture barriers are installed over the roof prior to proceeding with built up roofing. Alternating layers of waterproofing elements and bitumen are installed over the moisture barrier. It is the number of layers that determines the quality of the roofing. More the number of layers, better is the quality of the roofing.

Spray Foam Roofs

This is the flat construction roofing that uses foam made of polyurethane in order to provide a protective covering to the roof. Rigid sheets of foam insulation are fastened to the roof. The next step of this technique is to mix a foam solution and apply it to the roof with the help of a spray gun. In order to facilitate proper drainage, the thickness of the spray foam roof varies across the entire surface. An elastomeric coating helps hold the spray foam roof firmly in place. It also helps prevent fire accidents and provide water resistance.
