Residential Roofing

    • Roof structure

    The roof structure is the frame for the roof. Think of it as the bone structure of your body. Depending on the structure of your home, it’s either made of rafters, trusses, or beams and defines the shape of the roof. There are many types of roof structures, gable end, hip, mansard, dormered, and gambrel to name a few. Most residential roofs in this area are made of wood lumber (as opposed to steel used on commercial projects). The floorplan of a home and the final roof covering determine the roof’s structure. For instance, a house with concrete tiles is different than one with asphalt shingles because the roof structure must support the extra weight. Also, it is the roof structure that determines what the slope of the roof will be.

    • Roof sheathing

    When you drive by a home under construction and see bare sheets of flat material on top of the house, that’s the roof sheathing. It sits on top of the roofing structure and is secured directly to it. The most common material used is oriented strand board (OSB) because it’s lightweight, affordable, and available. Plywood is also used but mainly for roofs that will hold more weight, such as concrete tiles. Older homes (1900 and older) usually have skip sheathing. Skip-sheeting, or spaced sheathing, is just as it sounds: sheathing with gaps between. Traditionally, skip-sheathing consists of 1-inch by 4-inch boards nailed to the rafters with gaps between the boards. Spacing between boards is optimal for wood shakes but cannot support asphalt composite shingles. By RI Building Code, this sort of roof must be re-sheathed with plywood to support the new system.

    • Roof flashing

    In a perfect roofing world, every roof would have a small slope without any obstructions. But that’s not the case. Roofs have joints and structures like chimneys and ventilation. Flashing is what’s used to protect the roof around these areas. Its main job is to keep water from entering. Most flashing is a thin strip of material, generally metal. It’s placed in the valleys and around protrusions so water can be deflected and run off the roof. The roofing company typically decides the exact type of flashing. Appliances such as boots (around pipes) vents, chimney re-leading, and step and valley metal are all features of flashing.

    • Roof ventilation

    Your roof ventilation system is critical. When done correctly, it extends the life of the roof, reduces energy bills, and lowers indoor temperatures. There are two parts to roof vents – the exhaust function and intake vents. Many roof vents are installed underneath the roof covering at the roof ridge and roof edges, so you don’t even see them from the street level. When designed well and working correctly, the ventilation system allows hot air to leave the roof area while cool air enters.

    • Roof covering

    The top layer of the roofing system is your roof covering. Looking around, it’s not surprising asphalt shingles are the most popular roof covering in the United States because of their cost, fire protection, ease of installation, and durability.

    Cornerstone, with its years of experience, is well equipped to meet all of your roofing needs.

Commercial Roofing

Commercial Roofing is a process that utilizes material that is used to cover and seal the roofs of the commercial structures so as to insulate (R factor) and protect them.

The commercial roofing system conserves energy by reducing the consumption of internal energy. The materials used in these systems must be installed by a commercial roofer, registered with the RI Contractors Board. If your business is eco-friendly, then you can explore the possibilities for saving money and increasing sustainability with a solar roofing consultation with our partner, SunWatt Solar.™ Popular commercial roofing is by and large flat roofing. There are several flat roofing options such as TPO, EPDM, and PVC. All these flat roofing systems are economical to put up and are also durable. The life span of commercial roofing is easily 40 years or more if properly maintained.

A commercial roof typically has a flat slope (0/12 to 2/12) that is unlike anything seen in residential roofing (with the exception of porches and extensions). The best commercial roofing products are perhaps the Carlisleā„¢ or Mulehideā„¢ roofing materials. The membrane of such a ply is highly reflective with a white membrane that saves a lot of energy. Colors for the TPO are also available but limited. Properly installed is also leakproof with no maintenance. TPO roofing also resists the high winds because it is mechanically installed on your roof.

If the roof is built properly and is maintained well, then the longevity of the commercial roofing is huge, whether the roofing is for commercial or residential purposes. There are also some other advantages of the Commercial Roofing, like easier maintenance, lower temperatures within the building, and a lower load of cooling and heating on the HVAC systems.
