Understanding Roofing Estimates and Roofing Proposals

Understanding Roofing Estimates and Roofing Proposals

When it comes to getting a roof installed or getting regular roofing maintenance it is important to know the difference between estimates and proposals. The two are frequently confused because there are similarities, but there are key differences you need to know when it comes to the work you need to be done.

Understanding Roofing Estimates and Roofing Proposals


Estimates include the types of materials that will be needed for a particular project. It also includes the scheduled time for the project, cleanup, and the contractor’s liabilities and any relevant warranty information for the roof and materials. Estimates also include how the roof is to be paid for and if there could be any possible add on costs. Any potential add-ons will be explained in the estimate in full. There are some contractors that will try to use the estimates as a means of getting you to agree to and sign a contract, by acting as if it is a formal proposal. This is not what estimates are supposed to be used for. Estimates help you evaluate which roofer you may want to work with based on pricing, materials, and warranty information. A professional and trustworthy contractor will give an estimate to provide the specific details and costs that will likely be involved in your roofing project s you can make an informed decision.


A roofing proposal sets the cost for a project that the contractor and building owner are bound to, like a contract. Most roofers will have set costs for materials and labor and will provide these costs in full, so you know exactly what to expect. They also give a detailed breakdown for each part of the project, including any additional costs. Proposals give a final price that cannot be exceeded regardless of what happens during the project. If the proposal numbers are not one that you like, then you do not enter into a contract with the roofer. Be sure to discuss every aspect of cost with the roofer upfront so you will be aware of exactly what you will be charged for. You will want to know exactly what you are signing and what you are agreeing to.

Not all proposals are the same and they differ by project, contractor, and consumer demand. Some proposals will also be lengthy while others are much shorter. Beware of proposals that are too short because they should contain details and critical information. Shorter proposals may be missing important and critical details. Your roofing is an investment, so collect your estimates to make an informed decision. Then, discuss a detailed proposal with your contractor before entering any contract so that everyone is on the same page.

TPO vs. Modified Bitumen: What to Choose?


The two most commonly used roofing systems in commercial properties are TPO and modified bitumen. Modified bitumen roofing has been around since the 1970s and TPO developed later in the 1990s but they both are ideal for all types of weather and have advantages and disadvantages.

TPO vs. Modified Bitumen: What to Choose?

Modified Bitumen Roofing

Modified bitumen systems are practical and lower in cost than other commercial roofing options. Bitumen was an upgrade from traditional systems and offered enhanced longevity and flexibility, but many contractors have stopped offering these systems due to a number of disadvantages that were recently discovered. Modified bitumen roofing was designed to improve the original version by adding substances like APP (atactic polypropylene). This made sure that the newer systems were resistant to UV light, oxidation, cracking, and blistering. Unfortunately, some manufacturers do not use enough APP to save money and this means the modified bitumen roofing doesn’t stand up to newer challenges as well as expected. The granulated surface of these systems was also added to provide additional UV resistance, but makes it more difficult to identify cracks and leaks in the surface. These roofs also come with a serious fire hazard if there are any open flames nearby during installation.

TPO Roofing

Thermoplastic Polyolefin (TPO) roofing is the more modern choice in large-scale roofing and is installed typically in one of three ways; ballasted, mechanically fastened, and fully adhered. It has become popular because of the numerous benefits for building owners.
The single-ply membrane is tear resistant, UV resistant, and resistant to chemical and grease spills. They are also fully recyclable which is popular with today’s more eco-friendly society. There are also no plasticizers in the insulation which adds to it’s “green” image and appeal. You can also pick from an assortment of colors to match your building or opt for the traditional and energy-saving white. If the current roof is in good condition, you can apply TPO over existing metal or bitumen roofing. You save money and time because you don’t have to tear off and dispose of the old roofing. TPO is also reheatable and has a smooth and easy-to-clean surface as compared to the granules of bitumen roofing. TPO membranes are much thicker material which protects your roof from falling debris and tears.
You must always ensure that your roofing system is installed correctly as most of the problems detected with TPO systems have to do with poor installation. With quality and an experienced roofer that installs the system and welds the seams correctly, you can be assured that your TPO roofing will be more effective and will last longer than expected.

Whichever roofing material you decide to go with, we have the expertise and resources to get your new commercial roofing installed with quality and efficiency. TPO is the preferred option but we understand that sometimes traditional materials are great too. We are here to answer any of your concerns regarding your next roofing project and find the best fit for your roof.

13 Reasons Why Rooftops Are The Best

(A-One) 13 Reasons Why Rooftops Are The Best


1.Those views. Standing on a rooftop means you can see for actual miles.

2. Height gains. Especially important for short people who don’t know what it’s like to see over the heads of others…


3. Loads of cool space-saving stuff happens on rooftops in big, built up cities because there’s nowhere left on ground level. We’re talking vegetable gardens, beekeeping, and most importantly, bars.

4. You can probably see your house or workplace and it’ll make you feel like you’re in some super mega realistic Google Map.

5. Sunsets and sunrises will never look better than from the top of a roof.


6. If you have to climb a load of stairs to get up there, there’ll be some kind of view-based reward and you can tell yourself that you don’t have to go to the gym for another week.

7. The greatest movie scenes were filmed on the top of roofs; just look at Mary Poppins’ chimney sweep dance, King Kong’s accidental hostage situation and The Hangover’s pre-s@#$-hitting-the-fan Jager shots.


8. Extra special rooftops have extra special things on them, like tennis courts and movie theaters.


9. They’re the perfect spot for first dates because if you run out of chat, you can just spout on about the views until they tell you to shut up/kiss you to make you stop/run away.

10. It’s like being given a telescope over the city. You’ll spot buildings you want to visit, green spaces you want to roll around in and other rooftops you want to love life from.

11. The higher you are, the more cool points you’ll earn. “We had to climb one flight of stairs” wows no-one, but five is impressive.

12. The Beatles played their last ever gig on the rooftop of Apple headquarters in London in 1969.


13. Some rooftops have yoga classes on them which is the most zen thing ever.

What Kind Of Contractor Do You Need?

(A-One) What Kind of Contractor do You Need

There are a number of contractors out there, so there are a few things you should know before hiring one for your next project. It is important to find a reliable and licensed contractor to avoid financial risk and problems or damage to your roofing, which may come with unlicensed and unprofessional workers.

What Kind of Contractor do You Need?

In the state of California, any contractor that performs work on a project expected to value more than $500 for combined labor and materials must have a valid and current license from CSLB. You are advised to call and verify licenses for any worker you are considering.

Unlicensed Workers

Unlicensed workers pose a serious risk to your safety and your finances. Should a worker be injured while on your property and they are uninsured and unlicensed, you will take the hit financially. The majority of unlicensed workers also perform work at a lower level of quality which can lead to serious damage and expenses. In the end, it is not worth saving a few dollars by opting for an unlicensed roofer, because you risk paying so much more if anything goes wrong. When you carefully plan your project in advance, it is easier to identify and hire the appropriate contractor. You need to clearly define what you need done before deciding who is the best for the job. You typically get to choose between a general and specialty contractor and understanding the difference is important to your decision.

General Contractors

General contractors oversee projects and coordinate specific licensed subcontractors for any particular job. Specialty contractors, on the other hand, are hired to perform a single job. When you need a roofing project completed, you will hire a specialty roofing contractor to ensure you get someone that knows the industry best. General contractors can also contract for specialty work, but they must hold a valid license for that specific type of work. The only exception to this is when the project has more than two types of work involved. In this case, a general contractor will oversee the combined efforts of the project. The general contractor can hire subcontractors that have specialties based on the work that is needed.

Final Thoughts

There are many contractors out there to help you with your various installation projects. Understanding the difference between general and specialty contractors can help make the decision and hiring process smoother, and you can get the best possible work for your project.

What To Look for In Your Roofing Estimate?

(A-One) What To Look for In Your Roofing Estimate

Roofing estimates are not contracts and do not lock you into any deals with a contractor. These estimates are usually different and not universal in any way, which can be confusing. Some of them lack important information and others hide details that you need to know. Understanding what a roofing estimate should include will help you to make an informed decision.

What to Look for in Your Roofing Estimate?

To choose a reliable commercial roofing contractor and avoid any financial upset or budgetary issues, your roofing bid or estimate should have the following items:

  • Costs: Estimates need to spell out the projected overall cost of the job as well as give a breakdown of all expenses like materials, labor, and permits. There are some contractors that will omit some costs out so they can give you a low estimate and win your business. These unmentioned costs find their way onto the final bill and you end up going over your budget. If the estimate is inconsistent with the contract, then your prospective roofer has either made a mistake or tried taking you for a ride.
  • Products: Whether the project involves repairs, replacement, or new installation, the estimate should specifically say which materials will be used. It should also say what types of warranties will be included by the roofer.
  • Responsibilities: Your estimate should give you an idea about the services for which you’re going to pay. Many contractors will automatically add the fees for cleanup and debris disposal into the equation too. Manage your expectations when it comes to possible extra charges, as many roofers will charge extra for additional requests.
  • Start and Completion Dates: Bids are chiefly used for budgeting, but they can be helpful in scheduling, too. A good estimate will provide realistic roof replacement and repair project timelines, assuming there are no unexpected surprises during work.
  • Payment Terms: A reliable estimate explains how much the project will cost and how you can pay the bill. The contract will provide a more in-depth explanation, but the estimate should offer at least a brief description of how the proposed payment term works.

Entrust your roofing project to us and we will happily answer any questions about the estimate and the project at hand. We have many years in roofing and a reliable reputation. Contact us today to discuss your needs, get a free estimate, and get the best for your roof and wallet.

The History Of Roofing

(A-One) The History Of Roofing

As long as mankind has needed housing, they have needed roofing. Shelters are not very good without roofing. Caves initially provided shelter but the damp dark environment was not the most comfortable, so alternative shelter was sought. As far back as 40,000 BC, mammoth skins were used as a roofing material, which marked the beginning of the history of roofing.

The History of Roofing

Natural materials like sod or animal hide served as the best options for roofing materials. Materials like these have been used for roofing longer than more common trends like tiles have been around. China was the first country to use glass tile roofing almost 5000 years ago and today much of the architecture used still employs that same style. While the more modern materials used today are more popular, the original glass tiles are still used for special buildings like palaces and temples. Around this same time in history, Greece was using flat ceramic tiles. Similar tiles or shingles were created by the Romans and brought to England in 100 BC and these tiles were commonly used in roofing for wealthier areas all across Europe.

Since straw huts were designed, thatched roofing has been a key part of architectural roofing design. Ancient nomadic tribes would use wood bundles for roofing after it became difficult to find animal hides. The concept of thatching became popular and was used through the coming ages on many buildings because of its effectiveness. Thatched roofing remained a low-cost option, even as roofing continued to develop. Over the last 200 years, more modern materials have been developed and are used more commonly for roofing projects. Materials will continue to be designed to be more economically friendly as energy conservation continues to be more popular. Roofing today is for more than just protection and designs now incorporate ways to save money and stay aesthetically pleasing.

Roofing started with stretched animal hides over poles and stones and since then, major advances have been made. Protection and shelter is the main purpose of all roofing and materials were found and developed according to what was available. As we move towards the future, more innovative and technologically-advanced materials will be discovered, taking roofing into the next century.

5 Unexpected Places You Need Safety Railing

(A-One) 5 Unexpected Places You Need Safety Railing

Having safety railings in place makes sense for a number of areas; scaffolding, working at the edge of a roof or on a tall piece of equipment or building. There are also several places where you need safety railings that you might not realize. Specifically, there are five common situations where you should consider having safety railings before you work.

5 Unexpected Places You Need Safety Railing

  • Roof-to-Roof Drops: Many roofs are not single level and any changes in roof elevation can be a potential fall hazard. We typically think safety railing for the edge of the building perimeter, but forget about the significant elevation changes within the perimeter that also need safety and protection against falls.
  • Skylights: These give a false sense of security because there is no visible opening to alert you of a hazard. Most people do not know the true weight capacity of skylights which means they underestimate their strength and mistakenly stand on them.
  • Roof Hatches: Most people think that roof hatches are safe so long as they are closed, so safety railings are not installed. However, when people are working on the roof, the hatch is often left open to allow easy access back inside and you end up with is a serious falling hazard. A safety railing will prevent accidental falls if someone is not paying attention and serves as a handhold to provide balance as workers ascend and descend.
  • Wall Mounted Ladders: Ladders are typically placed near the edges of buildings and accidents can happen while waiting to use the ladder or during a climb. Workers are at risk of falling any time they use a ladder, so safety railing at the side of each ladder is the best way to protect from hazardous falls.
  • Parapets: Many people believe that parapets provide fall protection, but this all depends on their size. If you have a parapet over 21 inches you will also need to have safety railing too. Parapets should also be a minimum of 39 inches high to be considered appropriate for fall protection.

Safety comes first when working on a roof and often there are dangers lurking that we are not aware of. Take time to evaluate the situation and environment and identify potential hazards, even when they seem to be in the most unlikely places. Any dangerous fall can be prevented with the installation of safety railing, so identify the danger areas and get a roofing expert to have safety railings installed wherever they are needed.

Covering Rooftop Equipment with Roof Screens

(A-One Roofing) Covering Rooftop Equipment with Roof Screens

It is not uncommon for buildings to have equipment on the roof. The roof is a great place to keep bulky equipment as it is out of the way and for the most part, out of sight. Depending on where you stand though, the equipment can look very unsightly. Big, bulky units can detract from the appeal and appearance of your building, especially if any investors happen to be in the area. As important as it is to find space for your equipment, it is equally important to remember that the appearance of your building matters to partners, business prospects, and customers. Your brand and reputation could be at stake. Ventilation, heating, and electrical equipment are necessary components of a building, but this doesn’t mean they have to be out n the open for all to see. Investing in roof screens allows you to protect your brand and mage, by effectively hiding the bulky and unsightly equipment that your building needs.

What Screens Can Help You Hide?

Having roof screens can hide equipment from sight, thus protecting the appeal of your building and brand. There is a lot of equipment that can be hidden with the installation of a quality roof screen.

  • HVAC units – These are typically bulky and lined up in rows, but are necessary for climate and temperature management for the building interior.
  • Roof Exhaust Ventilation Fans – These are needed to pull dirty air from the building and allow fresh air inside. Bigger buildings have more of these and the more you have the uglier the roof looks.
  • Cooling Towers – These extract unwanted heat from various places to reduce the temperature of the water. These are prone to rust which makes them very unsightly.
  • Ducts and Pipework – Always associated with HVAC units and other roofing equipment, you can often see ducts and pipes from ground level.
  • Service Walkways – Often used on flat roofing and are necessary for accessing roof equipment. While functional, these are not great to look at especially when located near the edges of the building.
  • Platforms – Many forms of equipment come with platforms to raise them from the roof surface. The framework and equipment are more visible because of this and when they also have guardrails, they are even more distracting.
  • Solar Panels – As green energy becomes more popular, many buildings invest in solar panels. While the panels are not ugly and offer a unique look, the supports, frames, and electrical connections are not pleasant to look at.
  • Communication systems – Antennas, cellular communication units, and satellite dishes are necessary for communication but do nothing for the building look. You may not be able to hide a tall antenna, but a screen will definitely cover the bulky equipment at the base.

The equipment discussed above is required for the efficient functioning of any commercial or industrial building, but it can take away from the appearance and potentially your brand. Investing in roof screens will help to protect your image as it keeps the bulky units from sight. They can also serve as additional protection from adverse weather. Screen designs and materials vary so you can choose what suits your building and brand best. You can even add your company logo to the screens too. Call us today to discuss your screen options and we will make sure your roof looks its best without costing your reputation.

How To Cool Your Flat Roof?



Flat roofing is one of the most popular and efficient roofing options available, but they have one major drawback. Flat roofing is more prone to trapping heat than other roofing systems and this causes your building to be warmer and your energy costs higher. Manufacturers, however, have developed a number of solutions you can use to keep your flat roof cool all year round.

How To Keep Your Flat Roof Cool?

Roof Coating

Specialized roof coatings have been developed that will reduce heat absorption. Any of the materials below will help reflect up to 90 percent of the sun’s heat and light away so you can save on energy.

  • PVC sheathing: PVC sheathing is great for structurally-sound buildings. When applied to the entire surface, the heat-welded seams will keep water out while the smooth surface prevents wind damage. PVC sheathing is reliable for close to 15 years and can effectively withstand all weather conditions.
  • Elastomeric paint: The elastomeric polymer in this paint expands and contracts along with the material is applied to. When the bright white version is used, you will increase reflectivity and reduce heat absorption, so your building stays cooler and you can save on energy consumption.
  • Asbestos film: Low-sloping asbestos film shields can be erected over your roof to help increase reflectivity. These shields prevent heat absorption s your roof and building stay cooler. Just be sure to erect the shield so it does not catch prevailing winds and blow away.
  • Solar Photovoltaic panels: These thin panels are ideal for reflecting away the sun’s light and heat and they also store energy for future use. When used along with a PVC laminate roofing system, you can get the most efficient energy consumption for your building.

Other Cooling Options

  • Foam insulation: If you get a chance to replace your ceiling, then you should consider installing a layer of foam insulation under your roofing is ideal. This effectively regulates heat absorption and temperature, keeping your building warm or cool depending on the season.
  • Windcatchers: Windcatchers helps to direct cool air downwards. Their dome-shape and vertical weather vanes rotate with even the smallest breeze, forcing cool air down to the vents of the building. No need to worry about the weather when it turns cold, because there is a vent seal to keep cold air out.


Each of the solutions discussed above can effectively help you to reduce energy use and keep your building cool. Reducing heat absorption and keeping energy use to a minimum saves you money and keeps your roofing system in better condition for longer. We will work with you to get the right cooling option in place for you, so you can run your building more efficiently tomorrow.

How To Make Sure Your Roof Is Safe For Roof Repair?

how to keep roof safe for roofers

The roofing industry is responsible for almost 30 deaths out of 100,000 workers each year, making roofing repairs the 6th most dangerous job in the country. This is almost double the amount of deaths caused in the construction industry, so more attention has been given lately to ensuring workplace safety for roofing contractors. Reliable and professional contractors ensure that their roofing practices follow strict safety protocol. Workers are valuable and their safety is a top priority. It is important for you to schedule regular maintenance and inspection of your roofing to do your part in keeping roofers safe. The more you can do to help maintain your roof regularly, the less risk involved for roofing contractors.

Staying Safe During Roof Repair

With leaks being the top complaint in the industry, your need to identify and repair a leak right away is necessary. Leaks can be easily avoided by having a contractor regularly inspect your roofing, and if water does find a way through, you need to get the leak repaired immediately. This helps to avoid further damage to your building and a riskier roof for contractors to be on. Water that is allowed to get into the building can damage ceilings as well as structures. Materials such as ceiling tiles can become loosened, so they fall and damage equipment as well as cause injuries to workers within the building. In addition to this, water that seeps through can drip onto surfaces, increasing the risk that people will slip and fall.

The presence of water in the walls also promotes mold growth, especially on wood and gypsum drywall. The smallest patch of mold can release resilient spores that can easily spread to other surfaces within the building, causing extended damage. Mold is not only harmful to building structures but it can be dangerous to human health as well. There are two important factors you need to be aware of before repairing your roof. Firstly, the decking is an integral part of your roofing system, so if it is faulty in any way, you need to have it repaired or replaced. Without sturdy decking the roof will not last long. A roof with a short lifespan costs value to the building and costs you more money in the end. Ensuring you have solid decking is the best way to ensure the longevity and quality of your roof.

The second thing to remember is that waterproof materials are essential. You want to ensure that the roofing contractor you choose has a comprehensible waterproofing plan that includes effective means of preventing pools and leaks. The main cause of leaks is poor roofing, but this is avoidable if your roofer designs effective means of diverting water flow away from your property. Safety and quality are very important in the roofing industry. It is important that you hire a qualified roofing contractor to ensure your roof stays in optimal condition. A safe and reliable roof will protect your building and provides a safer working environment for contractors.
