Fort Worth Roofing: Article About Roofing Techniques
A low- or shallowly sloped roof is one that has a slope measuring less than or equal to 3 to 12. These roofing styles are popular on many types of homes in the southwestern areas of the United States, such as adobe homes, Spanish Mission styles, and others. While this construction method is economical and faster than building a moderate to steeply pitched roof, there is an increased risk of roof leaks. Experienced Fort Worth roofing experts can use several different techniques to protect low-sloped roofs from water intrusion.
Most shallow-sloped roofing systems have an extra layer or two applied to them on top of the wooden decking before any shingles or tiles are attached. These waterproofing layers are used to cover all of the roof's wooden surfaces to protect the wood from moisture and to facilitate drainage. Many of these products and techniques also help the fasteners to stay in place so that shingles and tiles do not easily blow off.
A backed bituminous membrane is one of the most popular protection systems for a roof with a low slope. This material is self-adhesive and installs quickly. The roofers cut it to size, with an overlap of 1 to 2 inches between strips of the material. All of the roof's surfaces, including the valleys and the ridge, must be covered with this protective material.

The membrane is non-perforated and can perform in sub-freezing conditions. It is a favorite material for roofers who frequently deal with ice dam situations.
Another innovative product available to roofers for low-slope roof applications is a liquid epoxy coating. This material goes onto the roof's sheathing like paint and then cures for a period of 5 to 12 hours, depending on the manufacturer's specifications. When the epoxy cures, it creates a watertight seal with the wood. Epoxy sealant can also be used on metal surfaces. Felt can be attached on top of the epoxy and then the roof can be shingled.
Asphalt lapping cement is another important product that is used to help seal up roofs with a minimal slope. The cement is applied to the first course of shingles as a way to enhance their bond with the sheathing. The cement bonds and seals up any gaps between the shingle and roofing felt where water could intrude. It can be used on the entire roof, but is usually just limited to the first course, as the lowest part of the roof is where the greatest amount of water drains.
