Shining The Spotlight On Roofing

Roofing is a vital element of building homes because most properties require something to provide shelter. Inevitably, roofing has advanced over time and, in particular, during the past twenty years. With the increased number of homes being constructed, more roofing options have become available. This satisfies both functional and aesthetic requirements. It’s incredible to see the number of choices homeowners have with regards to roofing. Here are some of the main types to be aware of:

Built-up Roofs

Undoubtedly, built-up roofs are regarded as a traditional roofing option. Devised more than 100 years ago, this roof type has stood the test of time — so it is a popular choice with many property builders. A built-up roof is not without its flaws because it can present some notable restrictions; however, many people who opt for this type are happy with their decision.

Typically, built-up roofs are used in high footfall areas and when the roof could suffer mechanical abuse. The membranes on these roofs are stronger and thicker than many other roof types. Both gravel surfacing and multiple layers are included. Due to this option’s popularity, it is normally simple to find Cincinnati roofers who can install and fix a built-up roof in most cities.

The primary drawback with a built-up roof is its inflexible nature. The roof might get damaged because of thermal or structural movement. Long buildings would require extra roofing support to stop contraction from harming the roof. Stretching because of warm temperatures or compression because of cool temperatures might also wear out a built-up roof. Maintenance is required if these issues are evident in a specific area.

A Modified Bitumen Roof

These types of roofs offer similar benefits and drawbacks as built-up roofs. Nonetheless, one distinct benefit of modified bitumen roofs is that they perform considerably better when cold. This roof type is designed to turn flexible if the temperature drops. It can withstand changes to the temperature better than built-up roofs.

Modified bitumen roofs come in a couple of types – the rubber-based models (SBS and SEBS) and the models based on plastic (APP). Typically, plastic-based membranes are fitted using torches, whereas the rubber membranes are fitted using hot asphalt or cold adhesives. The majority of these roofs have granulated surfaces already. This means that they weigh less than a built-up roof with a gravel surface. Besides, modified bitumen roofs might be used as cap sheets for older built-up roofs. This makes the roof tougher and more flexible.

A Single Ply Roofing System

As the name implies, a single-ply roof consists of one layer made from elastic or plastic material.Because there is just a single layer, this kind ofroofing is dense. Single-ply roofs are available in two categories: thermoplastic membranes, which have seams that are welded with a solvent or heat; and thermoset membranes, which have seams sealed with adhesives. The three kinds of single-ply attachments are loose laid, fully adhered, and ballasted. Thanks to their lightweight properties, single ply roofs are good for recovering. Also, they are reasonably affordable.Some single-ply roofs are sensitive to specific substances, so take care when selecting from different types of single-ply. PVC and EPDM-based materials might be harmed if exposed to jet fuel, cooking grease or oil. If emissions of this nature are prevalent in the neighborhood.

Metallic Roofs

Metallic roofs are no longer restricted to flimsy sliding panels that are fitted insecurely, then nailed or screwed onto a frame. These days, there are metallic roofs with concealed clips that are secure. These clips can be contracted or expanded. Possibly the most vital consideration, when selecting a metallic roof, is its lifespan: metal will not deteriorate, even after exposure to severe weather conditions. Some metallic roofs might have fifty year warranties. The drawback with metal, though, is the increased likelihood of leaks in comparison to other types of roofs. Leaks are a common occurrence, if metal is installed incorrectly.

10 Common Misconceptions About Roof Repairs

To be honest, the home’s roof is not highly thought of unless a major need develops. This is not a good way of thinking, let alone maintaining the home that you have come to love. Not only is a home’s roof an essential piece of your home, but it also requires upkeep.

With that, we’ve contacted local roofers to get a list of 10 common misconceptions about roof repairs that you need to be aware of.

01. No Leak, No Problem

A lot of times, when a leak occurs, they seem like they suddenly appear. However, when a problem develops and it is unknown, it can grow as time goes on, which can then create a leak. To alleviate any risk, your roof should undergo regular inspection. An inspection will point out all issues that may occur based on the roof’s current condition prior to any possible deterioration.

02. Layering Old Shingles with New Shingles is Fine

Although it is cost-effective, layering shingles on top of each other will hide any unseen issues underneath like rot and moss. Both of these are able to lead to a leak or prevent an attic from obtaining proper airflow.

03. Waiting to Replace Flashing

A roof’s flashing is necessary to shield the roof from water exposure and causing problems. A high percentage of leaks take place where flashing is. This is why your flashing needs to always be in a “like new” state. If you notice issues with the flashing, then replacing it must be immediate, regardless of if other areas are fine. Having an inspection of the flashing should happen at least yearly.

04. Increased Insulation Doesn’t Hurt

Having proper insulation will determine how well your roof functions. Of course, too little insulation is not good, but going overboard with it could also create concerns. When you go overboard with insulation, it may impede airflow coming in through the eaves and arches. Too much insulation will also prevent moisture from escaping and allows rotting and mold to develop.

05. There’s No Difference in Shingle Type

Many times a contractor will say that there is no real difference in shingle type. If you were told this, then you should not work with them. There are many types of shingles available on the market, which contain a different amount of quality.

Shingles are now designed to last longer than their predecessors due to the improvement of manufacturing methods.

Shingles now have a mix of fiberglass and lamination, which allows them to have a life-span of more than 55 years and are able to resist gale-force wind.

06. Identical Repair is Determined by Climate

Roof repair is not identified based on the climate that you live in because the various material used will also be different. If you live in a hot, dry climate, then your roof will experience damage that is nowhere near the type that you would see if the climate was colder or wetter. So, this will call for a different repair.

07. Self-Repair is Possible

Even though you may consider yourself to be a great handyman, repairing your roof yourself is not always a good thing to consider. There are a few reasons why including these:

• The roof repair is conducted improperly

• Possible safety concerns

• Current warranty will become void

08. All Roofing Contractors are the Same if Emergencies Arise

If an emergency happens to your roof, then you will need to ensure that the roofing contractor is perfect for the job. The last thing you want to do is pick the wrong one who is least experienced. Besides that, a contractor that is not certified as a roofer will cause your warranty to void due to the workmanship being below the warrantee’s requirement.

Other than this, it is important to be suspicious of any roofing contractor appearing unannounced shortly after a damaging storm hits. It is important to only work with roofers who are licensed, certified, and experienced so that you know that they will use products that are of the highest quality. Check out here for more information.

09. Installing a Metal Roof Prevents Ice, Dams, and Keeps Your Home Warm

Just because you have a metal roof, that does not make it more capable of stopping ice buildup and dams. Having appropriate ventilation and airflow is what actually puts a halt to any ice dam from forming, not the metal roof.

Keeping your home warm is also determined by the insulation and not the roof. In fact, it is no more and no less warm whether your roof is metal or shingle.

10. Every Repair is not Determined by Location

One thing to keep in mind is that there is no single style when it comes to roof repair. It is not an easy task when a repair is needed, and it involves more than knowing what material to use. This means all building codes need to be known as well as followed by the contractor.

To ensure that your roof repairs stay within code, then you are better off having a local roofing contractor conduct the repairs. They will be accustomed to the codes involved with the repair and can offer suggestions based on what works best for the area.

Selecting the Right Roofing For Your Building

Whether you want to choose a roof for a new building or you want to replace an aged one, there are many factors you will have to consider. Selecting the right roofing solution might not be easy because the roof that works for one building might be the worst choice for a different structure. The reason for this is that even if buildings might look similar, they might not be exactly alike. Because there are so many options on the market, you must know how to make the ideal choice for a particular building. There are several questions that you will need to ask before you make the ultimate decision.

1. What is this building’s mission statement?

Before you contact a roofing manufacturer or contractor, the first issue you need to consider is what you want to use the building for (the business’s mission statement).

Whether you are operating on the premises or you are actually building a new structure, make sure that the roofing solution you choose will deliver when it comes to your expectations. Usually, the type of building determines the appropriate roofing system.

Make sure that you know everything there is to know about the building. For instance, does the business have the intention to keep that building as an asset, and if so for roughly how many years? Is the company looking to expand its operations sometime in the future, or even change operations? How many occupants are there now, and how many are likely to be there in the future? You will also need to take into account factors such as maintenance and insulation requirements.

Generally, the starting point should be focusing on what the structure will be used for. For instance, a spec building will require a basic roof. However, special use structures like airline reservation centers will require a completely different roofing system.

2. What physical and other fundamentals affect the roofing choice?

Next, you need to assess the actual building. In this case, consider where the building is located as well as the surrounding area. Also look into things such as weather trends, building codes and the landscape.

The physical elements of the structure are also important. These include height, age, shape, design and size. You will also have to look at the building materials utilized to build the structure, as well as the place where the HVAC and fire protection systems are located.

In cases where you want to replace the roof, look at the characteristics of the roof area first. The characteristics include the roof’s shape, deck construction, size, slope, rooftop access, protrusions, edge detailing, as well as the current roofing structure.

3. What flexible-membrane roofing choices are there?

According to the SPRI, an organization representing suppliers of sheet membrane and other mechanisms to the roofing sector, there are three main classes of membranes which are thermoplastics, modified bitumens and thermosets.

Thermosets are made using rubber polymers. The popular type is the EPDM, commonly known as rubber roofing. This kind is made in such a way that it can endure the harsh effects of sunlight, as well as chemicals typically found on the roof.

Thermoplastics on the other hand, are made using plastic polymers. The most common type is the PVC. When plasticizers are added to the PVC they become more flexible. There is also the Hypalon thermoplastic which, although it starts as a thermoplastic, after some time it eventually curves and turns into a thermoset. A third type of thermoplastic is known as the thermoplastic polyolefin (TPO). It is basically a combination of PVC and EPDM.

The modified bitumens combine the formula and other benefits of flexible membranes with traditional installation methods used in roofing.

4. What is the perfect kind of membrane and attachment system for the building?

There are a number of factors which can help to determine the right roofing system for a specific building. Such factors include costs, wind exposure, aesthetics, height and expected roof traffic. The building’s attributes will also determine the attachment system. For instance, a ballasted roof could be the ideal choice in the vent that the roof deck can carry the weight. However, that choice might not be the best one if the roof’s slope is more than 2 inches per foot.

5. Does all the roofing material brought to the work site have the UL label?

Make certain that the roofing material which gets delivered has the Underwriter’s Laboratories label. These laboratories are responsible for testing all the materials used to make the roofing systems. Also ensure that the roof assembly which you opt for also has that label.
So, you have the responsibility of ensuring that the materials that you get will have gone through the necessary testing procedures. Avoid products that look similar to the original ones which have been adequately tested; what you want is a guaranteed product. Also make sure that the membrane has been tested together with the insulation.

6. Do you need a wind uplift rating?

Wind can cause a lot of damage to the roof, which can also cost you a lot of money to fix. This makes the uplift rating necessary. The American Society of Civil Engineers Standard 7-95 can help you to figure out the wind zone of a particular building.

7. How much does the finished system add to the overall weight of the roof structure?

It is important to have information about the load-bearing measurements of the roof deck before opting for a reroofing option. You want to be certain that you pick the correct flexible membrane. If it’s a new building, you can save on structural steel by going for a flexible membrane system which is a bit on the lighter side.

8. What are the skills and financial strengths of the roofing contractor you want?

You should choose a roofing contractor who has the requisite skills and experience. Over the last ten years, we have seen a lot of changes when it comes to roofing materials and installation techniques. Therefore, the contractor should have knowledge of the various kinds of roofing systems available. That way, he will be in a better position to give you the best advice, taking into account your budget.

One of the questions that you need to ask the contractor is whether his business is a member of an industry association; local, state, regional or national. You want to go for a contractor who is part of an industry association because of the added advantage of him having knowledge about the latest developments in the sector.

Because roofing systems are different, the way they are installed also varies. Make sure that you choose a contractor who has the requisite qualifications and training to install your roof. He must be up to date on current developments.

9. What is warranted and who provides the warranty?

Generally, there are two types of roofing warranties. There is what is called the contractor’s warranty which will cover workmanship. Then there is the manufacturer’s warranty and it will cover mostly the building materials; but some cover more items as well. Although the warranty provided by the manufacturer can cover other items, you will not be entirely protected if the roofing system has not been installed correctly.

10. After you have installed the roof, which services and educational programs are available afterwards for the facilities management team?

Manufacturers and associations such as the SPRI usually offer seminars to management teams. Such seminars help the teams to know more about commercial roofing systems; the various types available, as well as installation and maintenance requirements.
