Your Homes Existing Architecture May Affect Your Flat Roofing Replacement
If youve looked at all the alternatives and determine that a roofing conversion is really the best option for your home, its time to start planning your homes new architectural design. There are a couple of different ways to go about a conversion. You can install a shallow pitched roof over your existing flat roof, add a trussed ranch-style roof to convert to cathedral walls, or even build a new floor and install the pitched roof above that.
Either way, your homes existing design may interfere or affect the changes you can make. For instance, if youre not building a new floor into your home, your design may be limited if the existing ceiling joists arent arranged correctly. That means you may have to tear out the ceilings below the roof as well.
An architect or structural engineer should be able to provide advice on whats possible in your homeand what additional changes youll need to make before you can get your dream roof.

Flashings are weatherproofing barriers comprised of thin pieces of metal that cover the area where the roof surface meets an opposing surface, like a chimney or parapet wall. Flashings are essential for preventing water leaks in especially vulnerable areas.

Before bombarding the top of your home with a full outdoor renovation, make sure that you consider the weight of heavier objects, as these are likely to create depressions or ponding in the roof over time.

What Materials Are Good To Use On Flat Roofs
There are several types of roofing materials that are good for flat roofs. Some are primarily used for commercial roofing, and others are used for residential and commercial roofing.
Here are some common flat roof materials:
- TPO Stands for Thermoplastic Polyolefin it is made of polypropylene and ethylene-propylene rubber. It is white, which makes it a heat reflective roof that is energy efficient. This type of roof system is used on both commercial and residential roofs.
- PVC Membrane Is made from two layers of PVC roof material, then a polyester added in between the layers for reinforcement. PVC is generally more flexible than TPO. However, TPO is a little more weather resistant than PVC. Both are great to use on residential and commercial roofing systems.
- EPDM Rubber Is made of ethylene and propylene which are derived from oil and natural gas. EPDM Rubber is a very durable roof system that can last over 50 years. The downside to EPDM rubber is that it doesnt look as nice as the TPO or PVC Membrane.
- Modified Bitumen Given in its name Bitumen we know that its an asphalt product. It is can be a cold-applied or hot-applied system. It has a similar disadvantage to EPDM Rubber because its black it absorbs more heat than the white TPO and PVC systems.
Complete Flat Roof Installation

How To Determine Roof Pitch
You will also need to know the desired pitch of the roof. Pitch is the slope or angle from the wall plate to the roof ridge line. Pitch can vary a great deal, from a shallow slope up to a very steep pitch. Pitch for a gable roof, the most common, is generally 1/4 or 1/3 which is equal to 1/4 or 1/3 the total span of the building, not counting any overhang. Pitch also has its own denotation, determined by the rise in inches in 12 inches. For instance a 4/12 pitch denotes a roof rising 4 inches for each 12 inches. Having the correct pitch is important. In many instances, a certain pitch may be necessary or even required by local codes. Pitch is determined by snow loads, other weather factors and the covering to be applied to the roof. For those in the northern parts of the country, an 8 in 12 pitch, or more, is commonly used to keep excessive snow loads off the roof. Those in the southern climates may utilize lower pitches. The minimum pitch, however, that can be used with many roofing materials such as asphalt shingles or corrugated metal is 3 in 12 . For lower pitches, a built-up or continuous roll roofing must be applied to keep the roof waterproof.
Pitch is the amount of angle or slope the roof has. This is denoted two ways, a 1/3 or 1/4 pitch in fractions, and a 6/12 pitch in inches, which means the roof rises 6 inches for each 12 inches of run. A framing square is traditionally used for laying out the roof and determining pitch.

Why Flat Roofing Materials Are Different Than Pitched Roofing Materials
Pitched roofs have a physical advantage over flat roofs in their ability to let rainfall cascade down into gutters for drainage to the ground. Therefore, pitched roofing materials like asphalt shingles are engineered to ensure water flows well over the surface. Flat roof shingles tend to do more harm than good when it comes to protection from the elements. Water tends to seep between each shingle and can penetrate your roof membrane.
While flat roof systems are more affordable from the outset, they can be more expensive over the life of your building. Leaks are harder to diagnose and repair in a flat roof, especially on pebble roofs where you cant actually see the roof structure.
Until recently, flat roofs have had to be installed in multiple layers to protect against moisture damage and water leakage. Flat roofing materials have improved drastically over the past several decades to provide better waterproofing. Below, we review the best new roof material options for different types of flat roofs.
Pros And Cons Of Flat Roofing

The Advantages Of Flat Roofing
There are many people who prefer a flat roofing system over shingles or a tile roofing system. Here are several benefits of choosing a flat roof for your home.
Fill Depression With Wet Patch
Water will pool and potentially leak in depressions, so they must be raised to the level of the surrounding roof deck. Use the putty knife and wet patch to fill in the depression. Proceed immediately to the next step to avoid the patch from drying up on you.
Apply wet patch in temperatures greater than 0° F and less than 120° F. Though most wet patch repair products can be applied to wet surfaces, dry surfaces usually yield the best results.
