There are two basic methods of pitched roof construction;
- A ‘cut roof‘ – this is the traditional method of cutting the timber on site and building up the roof using rafters, ridge boards, joists and purlins etc – the exact details being determined by the size of roof, size of timbers etc.
- A ‘truss roof‘ – using factory made trusses which are delivered to site complete and just erected.
Current day building regulations require detailed calculation of the stresses, timber size etc used in roof construction, so factory made trusses are becoming the standard practice where all this can be worked out on a computer.
A cut roof
In simple terms this type of roof consists of rafters and joists. The joists prevent the outward spread of the rafters/walls, and conveniently give support for the ceiling below.
The size of rafter timbers will depend upon their length from the wall plate to the ridge, the type of roof covering and whether purlins are incorporated in the roof. It is more economical to keep the cross section of the rafters down, however where an open roof space is needed, larger rafters will be necessary. Typical rafter spacing is 400mm (16 inches), closer spacing will allow small section rafters and batten, that are fixed to the rafters to locate/fix the slates or tiles, to be used. The wider the gap between the rafters, the thicker the rafter and lath timbers need to be.
Rafters are nailed to a wall plate at the top of each supporting walls, these are normally 100x75mm (4×3 inches) timber embedded on cement mortar on top of the inner skin of a cavity wall, or the inner part of a solid wall. The wall plate timbers along the top of each wall should be joined with a half lap joint where they meet.
Each rafter has a small triangular section (referred to as ‘birdsmouth joints’) cut out of them to allow them to fit neatly over the wall plate. The top of the rafter is cut at an angle and nailed to the ridge board, typically 175mmx32mm (7×21/2 inch) mounted vertically.
Purlins, and the associated struts, are used to give some additional support for the rafters. The purlins run at right angles to the rafters, the associated struts are positioned under every forth (or so) rafter to attach to a joist above a supporting wall below.
Hangers, in conjunction with a longitudinal binder running at right angles to the joists, are used to help hold the ceiling up. Each hanger is nailed between the every fourth (or so) rafters and the joist below. The larger the joists size, the less likely there will be a need for hangers.
Collars, ridge collars and/or collars further down the rafters, are sometimes used to provide additional binding between the rafters on both sides of the roof. Where used, they are usually fixed to an occasional pair of rafters along the roof.
No part of a timber roof should ever be cut, modified, remove or the covering of the roof changed (i.e. replacing a slate roof covering by a concrete tile covering) without consulting a structural engineer.
A truss roof
A truss roof is made up of a number of factory made frames (or trusses) each of which which combine the joist, rafter and struts. The illustration to the right shows a typical truss for a simple Duo ridge roof.
Each modern roof truss is designed and made for a particular position in the roof structure and is made up of butt jointed timber lengths typically nailed together using plate fastenings – no type of timber joint being used. Historically truss timbers have been bolted together, or mortise and tenoned and then pegged.
As each truss is designed to form part of the complete roof structure, they should never be cut, modified or their use changed (i.e. replacing a slate roof covering by a concrete tile covering) without consulting a structural engineer.

If you’d rather enjoy the benefits of a cool roof without the addition of new surface materials or coatings, consider a roof mist cooling system. Also called an evaporative cooling system, a roof misting system lowers surface temperatures by spraying an extremely small amount of water across your Wilmington roof, allowing the water to cool the roof as it evaporates. This one of several green roofing options for keeping your roof cool and increasing the energy efficiency of your home. Discuss a full list of options with your Wilmington roofing contractor.
At its lowest-tech, a roof misting system can be little more than a garden hose set to the “mist” setting and aimed across your Wilmington roof. (The same method will also quickly and effectively cool your stone patio or wooden deck on a hot day.) Of course, more sophisticated roof mist cooling systems are much more practical for applications such as Wilmington office buildings and industrial space, as well as for regular residential use. Using sensors to measure roof temperature and moisture, these systems can lower rooftop temperatures by as much as 40 to 60 degrees Fahrenheit (4.4 to 15.5 degrees Celsius) on a hot summer day, while consuming less than one pint (473 mililiters) of water per square foot per day [source: Abernathy]

When you are ready to embark on a roof replacement for your Brunswick County home you should always prepare a list of questions to ask your Brunswick County roofing contractor before your scheduled appointments. There are many different styles of roofing materials, so you should take some time, and look online for the roofing type you want on your home.
What Are The Questions To Ask The Roofing Contractor?
- What Type Of Roofing Materials Do You Sell?
- What Type Of Insurance Do You Have?
- Do You Have Any References?
- How Many People Will Be On The Crew?
- How Long Have You Been In Business?
- How Long Will This Roof Installation Take?
- What Is Your Workmanship Guarantee?
- Does My Home Need Additional Ventilation?
What Are The Different Roofing Types?
There are several roofing materials from asphalt roofing, steel or metal roofing, ceramic roofing, and single ply rubber roofing. Most Brunswick County homes have either asphalt or metal roofing panels as the roofing products, and on the flat roofs like dormers single ply rubber is also used. In tropical or different regions ceramic or terracotta roofing materials which can be used. All of these products are great for waterproofing, and are very easy to find information about online.
What Roofing Materials Are Best?
In different parts of the country, roofing materials will change because of weather conditions. In Maine people use a lot of steel roofs because of the heavy snow fall. In Florida the choice of roofing is tile because of the heat, and asphalt shingles are used all over the country. There are also special asphalt roofing shingles for high winds along the coast, and flat line wind storms like in North Dakota and surrounding areas.
What Insurance Is Required For Roofers?
As you can understand, roofing is a very dangerous job, and not all liability insurance is the same. Roofing liability insurance is usually about 200 percent more than basic carpenter liability insurance, and excludes roofing completely. I have seen many insurance binders over the years from roofer who has only purchased basic carpenter type liability insurance, and when a problem occurs the homeowner will not be protected or covered under this type of policy. As a Brunswick County homeowner, you need to have the insurance company send you a copy in the mail with your name on the binder, and make sure that the policy includes roofing.
The next insurance that your Brunswick County roofing contractor should have is workman’s compensation insurance, and this is where you could lose your home if someone is killed or seriously injured. In most homeowners insurance policy’s it is clearly stated, that anyone you hire to perform work on said property must have workman’s compensation insurance. And you are responsible to make sure that they have this workman’s compensation insurance before you hire them to start the work on your home.
What Should I Need For Ventilation?
The reason a home should have ventilation is to remove the moisture from the home. Prove fact is that each person in the home permeates about 3 gallons of water a day. From showers, to cooking, and breathing water vapor is created and need to be able to leave the property. One of the largest reasons is to allow the attic to breath, and remove all the excess heat from the attic. Roofing manufactures want the attic to be the same temperature as the outside at all times. This adds life to the roofing materials but also helps you save money on your heating, and cooling cost.
How Many Estimates Should I Get?
You should get at least 3 roofing estimate from reputable Brunswick County roofing contractors to ensure the size of the roof, and compare the roofing materials, and pricing. Caution, do not only make your decision on the price, and you as the home owner must assume some of the responsibility if you insist the contractor lowers his price in which he cannot possibly by the materials, and supply the necessary labor to complete the job correctly. To do the job right the roofing contractor will need to pay for the materials and insurance then hire qualified installers to effectively complete the roofing work. Plus the roofing contractor will need to pay for his tools, equipment, and his vehicles plus additional over-head to manage the job correctly.

Like many systems in your Brunswick County home, no one thinks about the roof until something goes wrong. Usually, the first sign of roof issues is a stain on the ceiling. Believe it or not, that is a good thing. Think of it like the check engine light in you car telling you that there is something that needs to be addressed.
In other cases, the water follows the path of least resistance, showing little or no staining until there is a sudden blooming of mold on the walls.
Irrespective, once you know you have a roof problem, you have three way to address it; your Brunswick County roofing contractor can perform a roofing inspection to determine which option is appropriate for your roof.
- Repair the roof
- Restore the roof
- Replace the roof
Repair the roof- This is your least costly alternative. Unless the entire roof is failing, most leaks can be traced back to a point of origin. Depending on the size of the leak and the amount of damage, there are multiple ways in which to make a repair that range from invisible to ugly. A repair is an identifiable point of water intrusion that can be fixed. This does not guarantee that your roof will stop leaking, just that a single point won’t. Keep in mind that in some cases shingles will have to be replaced and it is next to impossible to match new shingles with the ones on your Brunswick County roof that have been exposed to the elements for years.
Restore the roof- Some roofs not only have leaks but the shingles are losing the aggregate (sandy stuff) that protects the body of the shingle. This type of roof should be replaced but sometimes you need time to acquire the funds for a roof replacement. With modern sealants the entire surface of the roof can be protected from further degradation. A roof restoration can extend the life of an older roof from 1-5 years and is less than ½ the cost of a roof replacement. It is not always possible to restore a roof and each one must be addressed on a case by case basis but when it can be done it gives the roof a sheen and a much newer appearance.
Replace the roof- Most expensive but most effective. This involves stripping the entire Brunswick County roof, nailing the roof deck to current code and installing a heavy felt and dimensional shingles. This should also include a wind mitigation inspection that will lower you insurance costs. Installed and vented correctly, a new roof will protect your structure for years to come.
Your business and personal objectives will define your choice but you should have as many options available as possible.
The same choices apply for flat or sloped roofs.
Not only does your roof act as a deterrent to moisture intrusion, it is also an important element in regulating the interior temperature and comfort of your Brunswick County home. A roof with the proper elements can save you thousands on energy bills as well as extend it’s own life.

Top 5 metal roofing myths for your reading pleasure!
It is truly fascinating how many people are clueless when it comes to the basic understanding of metal roofing. Not too long ago, I myself had the old rusty barn roof image in my mind. But now, after having been involved with metal roofing for 6 years I have developed a true appreciation for this roofing technology, and I would like to share some of the insights with you.
After reading these tips you will gain a better understanding, and appreciation of metal roofing technology.
Myth 1: Metal roof has a higher risk of getting struck by a lightning. Reality; No, metal roofing does not increase the chances of your Brunswick County home getting struck by a lightning. In fact, if your house does get struck, a metal roof will help to dissipate the charge, and because metal is a non combustible material, your roof will not catch fire.
Myth 2: Metal roof makes a lot of noise when it rains.
Reality; You are probably thinking about that old cheap metal roof over the barn that used to sound like a machine gun burst when it is raining… Modern metal roofing is usually installed over a plywood, solid sheathing, or over your existing Brunswick County roof. It will make no more noise than a regular asphalt shingle roof. Oftentimes a metal roof will be quieter than a non metal roof, and will shield the noise from rain and bad weather.
Myth 3: Metal roofing costs a lot of money.
Reality; It may seem like it does, but it really does not! You may be surprised, but metal roofing will actually costs less than the asphalt shingle roof if you stay in your Brunswick County home long enough. Not only will it increase the value of your house, but it will also help you save money on cooling costs. Metal roofing can result in up to 50% savings in energy costs during summer months. And finally, a metal roof may well be the last roof you will ever have to install on your house. Ever! Provided you get a quality installation from a qualified Brunswick County roofing contractor.
Myth 4: Metal Roof is susceptible to rust.
Reality; Modern metal roofing is built to last for decades. Steel metal roofing has a metal coating protection layer made with zinc or aluminum, which is bonded to the steel and then painted with a high quality paint designed to withstand the toughest abuse from bad weather, and provide the desirable color and looks that Brunswick County homeowners want.
Myth 5: Metal Roof is susceptible to dents.
Reality; Modern metal roofs are built to withstand years of abuse from severe weather such as hail, extreme winds, and snow. Hail will not dent a metal roof, and extremely high winds are not a threat either, as many modern metal roofing systems are rated for 120mph winds. In fact, metal roofs perform extremely well in the hurricane. It is not unusual to see the metal roof with no damage, next to naked regular roofs that have lost all their shingles and plywood in hurricane.
Bonus Myth: You cannot walk on metal roof without damaging it.
Reality; While you should definitely take all the necessary precautions before venturing out for a walk on your Brunswick County roof, metal roofs are completely walkable. I would recommend using running shoes because they will provide good traction for your feet when on the roof. Avoid walking on your roof when its raining, as you could easily slip and fall. Rule of thumb is to stay of the roof whenever its surface is wet. Contact your Brunswick County roofing contractor for special techniques on how to walk on the metal roof they have installed.

Owning a Wilmington home comes with its own maintenance list. Some jobs are small and others are ones that we would rather do without. Rain gutter cleaning is one of those chores that is required, but does not rank high on the fun meter.
A home’s gutter system is an intricate network that keeps the foundation safe and intact. Without it there is a myriad of complications that can arise – all of which can lead to costly repairs. That’s why it is vitally important to insure that the gutter system is free of debris.
It is necessary to keep the gutters free of leaves at least once a year. Late winter or early spring is the best time since you have accumulated all of the leaves from fall. You will certainly want to clean your gutters before the rains start in Wilmington. Try to clean them out any earlier than the last drop of leaves and you will just have to repeat the process. If you happen to have a lot of trees over or next to your Wilmington home, it may be necessary to clean them out twice per year.
To properly complete the rain gutter cleaning task, you will need a tall ladder, an old broom or mop handle and some basic tools. A hand broom, similar to one for brushing out a fireplace, will be useful for brushing the leaves together. Use the broom or mop handle to push debris down the gutters towards the bottom. You may have to take a hose with a strong spray nozzle and use the water in a jet stream to finish pushing them all the way down. You should be able to tell when they are clear by looking down inside and seeing daylight from the bottom hole.
Alternatively you could use the scoop method of lifting leaves and debris out of your system. Try pushing it all to one spot with the broom handle or water jet and then use a simple trowel to lift out the leaves. Depending upon the size of your gutters, a small hand spade may do the trick. One benefit of this method is being able to toss the debris and leaves into a catch-all that you can easily move to your compost bin or Wilmington garden as mulch. However, you will have to be careful not to damage your gutters.
The tools are for minor repairs that you find during your rain gutter cleaning efforts. There will undoubtedly be some loose connections here and there that you can tighten. Better to do it while you are up there than to have to make another trip. While doing your rain gutter cleaning do some inspection of the gutters for shingle debris. If there are a lot of flakes that resemble small, black gravel from the shingles then you may want to have your Wilmington roofing contractor come out to inspect your roof as well.

Here is the scenario that many Brunswick County homeowners have experienced: The roof is leaking; it’s been on for 12 years and this isn’t the first time you’ve dealt with it leaking. The question going through your head is: Should I repair or replace my roof?
There are several points to consider when trying to make this decision, and keep in mind that no two roofs are the same. So while there are general guidelines you can follow to help you decide, keep in mind that you know your roof the best and you know whether there are other considerations that you should keep in mind. your Brunswick County roofing contractor can also advise on whether a roof repair or roof replacement is your best alternative,
Special Considerations:
o If more then 30 percent of the entire roof is damaged, or if there is extensive moisture damage to either the existing roofing layer or the structural deck, you should consider replacing the entire roof.
o If your roof damage occurred as a result of a storm such as a tornado or hurricane, then you should certainly consider replacing the entire roof. In these situations, there are is often damage that you cannot see and it’s important to go ahead and replace the roof. Safety for you and your family is the most important factor.
o Is there a pre- existing condition on your roof that would make it beneficial to go with a full roof replacement?
Consider replacement if:
o You think your roof has a faulty design
o Improper material was used while constructing the roof
o There were past problems with mold or algae growth
Factors to consider:
o Interior Walls- Two sure signs of major need for roof repair are if the walls and ceilings in your Brunswick County home have moisture marks and if the paint on your walls and ceilings are peeling.
o Torn or Missing Shingles- Torn or missing shingles could be caused by many variables from heavy sun to tree branches being improperly removed from the roof. Sometimes torn or missing shingles are a sign of a simple roof repair but there are times that it is the clue that there are more serious roof issues. It’s always important to consult with a skilled Brunswick County roofing contractor who can help you determine the severity of the problem.
o Roof Layers- If you have more than 3 layers on your roof and are again experiencing problems then it’s time to replace.
o Roof Age- If you have an asphalt shingled roof of good quality material and installation than it should last between 15-20 years. If your roof is over 12 years and experiencing roof leaks associated with other roofing problems then you should seriously consider replacement.

Looking for a way to reduce your energy consumption in your home or business? Consider solar (photovoltaic) shingles. A relatively new green product, photovoltaic shingles are electricity-generating solar shingles that can be an excellent option for both new construction and homes in need of a roof replacement or upgrade.
St. James solar shingles give a home or business the ability to independently generate electricity directly from the sun when needed, reducing your energy bill in the process.
Solar photovoltaic shingles are solar cells designed to look like conventional asphalt shingles. There are several varieties of St. James solar shingles currently available on the market.
- There are shingle-sized solid panels that replace current shingles in a row. In this sense, they will look similar to the current shingles on your roof.
- There are also photovoltaic shingles that are more solid design characteristics. These tend to contain a number of silicon solar cells and look more like traditional shingles.
- Finally, there are newer systems of St. James solar shingles. They use thin film solar cell technologies and are similar to regular shingles in terms of both size and flexibility.
How Photovoltaic Shingles Work
Adding photovoltaic shingles to your roof can be completed in a similar process as getting a new roof. Both solar panels and a roof can be installed at the same time when photovoltaic cells are integrated into the roofs construction, which saves time and Installation costs.
Photovoltaic cells convert energy from light into electricity. Therefore, these cells create electricity by absorbing photons and releasing electrons. The more St. James solar shingles that are linked together in the system, the greater capacity they have to produce more energy.
On average, each shingle can produce up to 50 watts of electricity. This adds up to a considerable amount of energy generation if your whole roof was covered with these shingles.
Once in place, the sun’s rays act as a bonding agent between the shingles and help to form a weather resistant seal on the roof that can withstand poor weather and high winds.
Benefits of Photovoltaic Shingles
Home-owners may be drawn to St. James solar shingles because of the many benefits this roofing system can provide:
They are aesthetically pleasing
Solar shingled roofs have a dark purplish-blue color, and just as good as a normal roof.
A Fully integrated shingle roof
These systems are architecturally great and exceptionally durable. They are wind and water proof with no support structures or systems needed.
A lower electric bill
Why pay for the electricity when you can generate it yourself.
Protects the environment
St. James Solar shingles provide pollution-free power
A Great investment
Since St. James solar shingles will save you so much on your electricity bill, the return on the investment is great. They will also help increase the current value of your home.
Potential Tax rebates
Installing St. James solar shingles is not only a great choice for the environment; you may be eligible for a tax rebate.
