General Information

We don’t “guesstimate” your estimate – we offer professional and accurate estimates along with fair and equal pricing.

Contractor John Cadwell’s home is designed with a hip roof and has Architectural 30 year Shingles installed on it.

Affordable Roofing by John Cadwell, Inc offers up to 15 years Limited Workmanship Warranties. Unlike most of our competition we provide a Written Workmanship Warranty. See warranty for details.

All Shingle, Metal, Tile, Modified and Restoration roofing systems come with Manufacture Warranties which varies. View a listing of several manufacture warranties on our Warranty page to compare. We understand that there are several types of roofing materials, however, we do not offer certain roofing materials to customers, because in our 2 Decades of roofing in Florida and hearing responses from our customers and dealing with manufactures we do not recommend certain products that have had, in our opinion, poor customer and contractor responses from the manufacturer. Our interest is always the customer not our own special interest.

Roofs all need maintenance just like a car. Small isolate problems can cause your roof to have a shorter life span. Regular inspections can add to the life of your roof. Problems left undetected or ignored will over time cause extensive and expensive repairs or even replacement. Gutters need to be cleaned out at least twice a year. Caulking all windows, doors and other openings yearly is also a key part of maintenance.

All roof systems are susceptible to deterioration brought on by chemical and physical stresses that represent the normal aging process. As this deterioration occurs, small isolated problems such as leaks and loose shingles can not only accelerate the aging process, but also create a situation where your roof will fail. If left undetected, these small problems can escalate over time until the damage is more extensive, and expensive to correct.

We do not recommend painting your roof; however, roof waterproof coating systems may be applied to most roofs

A few local government agencies and private companies have started recycle programs for used shingles. The shingles can be recycled into road paving material and other materials. We do recycle roofing shingles if your jobsite is located with an area that offers it. Check out our Recycling page for more information.

Roofs that have slopes of 4:12 or less are considered to be low slope roofs.  (4:12 means a vertical rise of 4 inches for every 12 inch horizontal run, or 18.4°). Never apply asphalt shingles to slopes that are below 2:12 (9.5°).  Shingles applied on low slopes do not last as long as shingles on steeper roof pitches, due to the increased exposure to sunlight and other weather conditions.  Generally, laminated/architectural shingles are better suited to steep roofs, and do not offer aesthetic benefits when applied on low slopes.

Although the roof design may be beautiful it does not mean it is functional. Troublesome and costly roofing problems are often the result of faulty initial design of the roof system. Water should always flow easily away from the roofing system. All downspouts should be diverted away from all roofs. Standing/Ponding water for any amount of time will without doubt cause damage. Make sure that your roof is always designed properly.

Installing a Roof

Replacing a roof is a labor-intensive project. It could take anywhere from 1 day to 2 or more weeks depending on the size of the roof and the amount of damage. Like many construction trades, roofing is substantially affected by the weather. Poor weather conditions could delay a project or prevent crews from finishing a job already in progress.

Yes, but we only offer our Limited Workmanship Warranty to the work we performed not including Tied-In areas. If you are interested in a whole roof Workmanship Warranty a Roof Certification will need to be performed at a additional charge. Ask us for details.

The condition of the existing roof determines whether you can add another layer of roofing materials. Relaying is not recommended for roofs with existing shingles that are curling, moss covered or splitting. The contractor should inspect the roof for sagging or rotting decking, which indicates problems requiring more than a simple addition of new roofing materials.

The type of shingles for the new roof must be of the same material as the original roof. When placed over heavyweight shingles, lightweight shingles reveal all the ridges and lines from the original roof. Metal Roof-overs may also be an option.

The Uniform Building Code states that only two layers of roofing material will be allowed on any residence, so there can only be 1 layer of existing roof. It is typically better to remove and replace the roof, this will allow any existing sheathing damaged to be exposed and corrected whereas a Roof-over does not permit this.

Most solar panels are bolted or mounted onto the roof and will have to be removed by a licensed professional. The size and complexity of the panels will determine the cost of proper removal and re-installation. Removing solar panels ensures that the new roof will be installed correctly. While most roofing companies have owners remove the panels and then just leave them down for the owners to arrange to have them reinstalled, we offer an all-inclusive package and handle your removal and set up for you.

As a rule, the vibrations from removal or installation of roofing materials may cause items to shift or fall from the walls and shelves. You may opt to cover anything in the attic with plastic or a sheet as it will get dusty. Make sure the driveway and surrounding areas are clear so the crews have space to move materials and collect debris. To minimize risks, park on the side of the road instead of on the driveway.  Any items that may be shaken loose should be removed until the roof is completed.

Depending on the type of product requested, our estimates on average take approximately 45 min.

The answer depends on many factors. Costs will vary depending upon the material chosen, type of ventilation necessary, and the costs of permitting in your area. Roof-Overs – laying a new roof over an existing roof, often costs less than a full tear-off. Mitigating factors, such as the presence of dry-rot, asbestos, or lead-based paint, will also increase costs.

Almost anytime is a good time to install a roof. As long as the temperature is above freezing and there is little chance of snow or rain, a roof can be installed. We work all year long and take extra precautions to ensure that the house stays watertight during poor weather. Some phases of construction can even be performed in the rain, but it’s best to avoid inclement weather.

Missing and damaged shingles or tiles will cause leaks that will cause your plywood or wood to rot and end up with major problems. If water gets inside your house, it may destroy your drywall and personal belongings. So if you see your shingles damaged, missing, they are experiencing leaks of any sort, or any unleveling on your roof, avoid disastrous damage and insurmountable costs and get your roof taken care of today.

The key to a roof system’s effectiveness is complete protection. When shingles are missing or torn off, a roof structure and home or building interior are vulnerable to water damage and rot. Missing or loose shingles should be replaced as soon as possible.

Signs of bad roofs are damaged or missing shingles, experiencing leaks of any sort or any unleveling to your roof that you may notice. If you notice any blistering or peeling of paint, stains on wall or ceilings, a decay of sheathing siding or stucco may also be signs of the need for a roof replacement.

When shingles are old and worn out, they curl, split and lose their waterproofing effectiveness. Weakened shingles are easily blown off, torn or lifted by wind gusts. The end result is structural rot and interior damage. A deteriorated roof system only gets worse with time-it should be replaced as soon as possible.

Many apparent roof leaks are usually flashing leaks. Without good, tight flashings around chimneys, vents, skylights and wall/roof junctions, water can enter a home or building and cause damage to walls, ceilings, insulation and electrical systems. Flashings should be checked as part of a biannual roof inspection and gutter cleaning.

Roof Environment

Traffic on a roof can cause damage. Although Christmas lights are very attractive, we never recommend putting them on your roof, it is important to keep the roof clear of all types of items. If you notice a problem with your roof we recommend you to call a professional Roofing Contractor do not attempt to take care of it yourself

A/C units and other kinds of equipment that cause a vibration on roofs may result in the premature failure of roofing systems. All equipment should be maintained on a regular basis.

Tree branches touching a roof will scratch and gouge roofing materials when the branches are blown by the wind. Falling branches from overhanging trees can damage, or even puncture, shingles and other roofing materials. Leaves on a roof system’s surface retain moisture and cause rot, and leaves in the gutters block drainage. Moss can grow on moist wood shingles and shakes and algae also can grow in shaded, damp areas. Once it grows, moss or algae holds even more moisture to a roof system’s surface, causing rot and deterioration in addition to a greenish-black stain. In addition, moss roots also can work their way into a wood deck and structure. Trees and shrubs should be trimmed away from homes and buildings to eliminate damp, shaded areas, and gutters should be kept clean to ensure good drainage.

Once water gets underneath shingles, shakes or other roofing materials, it can work it’s way to the roof deck and cause the roof structure to rot. Extra moisture encourages mildew, mold and rot elsewhere in a house. Condensation can result from the build-up of relatively warm, moisture-laden air. Moisture in a poorly ventilated attic promotes decay of wood sheathing and rafters, possibly destroying a roof structure. Sufficient attic ventilation can be achieved by installing larger or additional vents and will help alleviate problems because the attic air temperature will be closer to the outside air temperature. High winds can lift shingles’ edges (or other roofing materials) and force water and debris underneath them. Extremely high winds can cause extensive damage.

Ultraviolet rays and heat can cause roofing materials to become dry and brittle and to deteriorate over time. Areas of the greatest concerns would be on the south and west side of the building where deterioration can occur faster.

Unfortunately, roofs are not maintenance free and should be blown off and inspected at least once a year. On homes with valleys, where two roof planes meet at a downward sloping angle, debris may become impacted which could lead to water damage. Tile roofs may require more frequent maintenance as leaves and debris can get stuck underneath the tiles. Routine maintenance can be anything from keeping drains and gutters clean to cutting back tree branches. Some roofs that have shading may show signs of algae which should be removed by a roofing professional not a pressure washing company.

Gutters should be cleaned at least once in the spring and once in the fall. Failing to clean out gutters could cause water to back up into the roof system and create dry-rot, interior damage, or mold. When cleaning gutters, make sure to flush downspouts. Clogged downspouts could cause water to back up into the house.

The constant, year-round movement of air across the attic is a process that can improve home comfort, reduce damage to the roof structure and help keep a roofing warranty valid. Every time stale, overheated air is vented out of the home, and fresh air is pulled in to replace it, you have an “air exchange.” The process of air exchange is more than a breeze moving through the home. It’s a process that provides a steady, high volume of air movement. It’s a system of components, all sized and positioned to create a balanced flow of intake and exhaust air moving though the attic.

Roofing, like any other material, will deteriorate with time. A new roof can last between 15 and 50 years depending on the roofing material and how well it’s maintained. Choosing the right contractor will also contribute to the length your roof will last. Experienced contractors will make fewer mistakes than novice roofers. Some companies may cut corners and deliver an inferior product in order to keep their costs down. Many owners neglect their roofs and fail to maintain them properly because they are unaware that their roof needs maintenance or because they think it will cost too much. Any one of these factors could shorten the life of your roof.

With over 20 years of providing roofs to businesses and residents of Florida, and with thousands of successful, watertight roof installations, and the best written labor warranty in the industry Affordable Roofing will only do closed valleys, also known as weaved valleys for shingles and open valleys for metal roofs and tile roofs. How your roofing company installs a roof valley can define their roofing skills and really show there experience and knowledge and at Affordable Roofing we will not do your roof valley with the other inferior valley options.

The short answer is YES. However, owners are responsible for making sure materials meet the required standard and are approved for use in Florida according to their local County or City Building Department. Don’t be surprised to find out that not all materials sold or delivered in Florida are approved for use in Florida. This was especially apparent during the Hurricanes of 2004. Materials were shipped into Florida that were tested for use in Snow states, not Hurricane states like Florida. Different roof coverings have different ratings.  If you require a review of your products or a breakdown list of what you will need we will provide this for an additional charge. Contact Affordable Roofing for more details.

Poor ventilation causes roofing materials to wear out prematurely. Heat builds up under the roofs surface causing shingles to crack and curl up from the outside. Inside, heat builds up in the attic, which increase utility bills and bakes the roof from the inside. Without proper ventilation, moisture can also build up to create mold and mildew. Eave vents suck cool air into the attic while ridge-vent or off ridge-vents exhausts it through the roof plane creating a vacuum that constantly circulates air. These products offer an inexpensive way to extend the life of a roof and keep utility costs down.

A skylight is a structure that allows light on the roof to travel to the interior of a building. Skylights are particularly useful in spaces that do not receive much natural daylight; for example, walk-in-robes, hallways and rooms next to patios or verandas.

Drip edge, aka eaves edge metal, is used for water shedding at the eaves and rakes and for preventing wood materials from rotting. It is important that the drip edge is made of a corrosive-resitant material that extends back from the roof edges and bends downward over them.

Affordable Roofing by John Cadwell, Inc agrees with the and supports the current building code standards that nails are the preferred method of fastening asphalt shingles and screws for metal and tile roofs. A minimum of 6 fasteners for shingles and __ for metal and tile.

There may be some tax advantages with using ENERGY STAR™ approved shingles in some areas; check with your local, federal or state government.

Architectural shingles are a type of shingle that appears or tends to look like a wood or shake shingle. It is a composite material, like a normal 3 tab, but its design and how it lays makes it a more durable shingle with a longer warranty.
