While it is more invasive and expensive than restoration, a residential roof replacment may be more of an initial investment, but can save money in maintenance expenses in the future. Depending on the age of the respective roof system, Keystone Contracting Group, Inc. will present a myriad of residential roof replacement solutions that meet our client's budget, mitigate disruptions to their daily operations, and afford a long-term roofing investment. Keystone Contracting Group even starts off any concerned homeowner with a free roof inspection to begin their journey to a safe and beautiful roof.
Our team at Keystone Contracting believes it's important for our customers, and any homeowners at that, to know the anatomy of their roofs; this idea is to, not only, know when your roof might be in need of a roof replacement, but to also have a first-hand idea of what our team guides you through in the roofing process, as we maintain full transparency with the homeowners.
A few roof system components to be aware of on all steep-slope roof systems (i.e roofs with slopes of 3/12 pitch or more) have five basic components:
- Roof covering: shingles, tile, slate or metal and underlayments that protect the sheathing from weather.
- Sheathing: boards or sheet material that are fastened to roof rafters to cover a house or building.
- Roof structure: rafters and trusses constructed to support the sheathing.
- Flashing: sheet metal or other material installed into a roof system's various joints and valleys to prevent water seepage.
Drainage: a roof system's design features, such as shape, slope and layout that affects its ability to shed water.
Choosing a Roof System
There are a number of things to consider when selecting a new roof system. Of course, cost and durability head the list, but aesthetics and architectural style are important, too. The right roof system for your home or building is one that balances these five considerations.
A roof system's performance is affected by numerous factors. Knowing about the following will help you make informed roof system buying decisions.
- Sun: Heat and ultraviolet rays cause roofing materials to deteriorate over time. Deterioration can occur faster on sides facing west or south.
- Rain: When water gets underneath shingles, shakes or other roofing materials, it can work its way to the roof deck and cause the roof structure to rot. Extra moisture encourages mildew and rot elsewhere in a house, including walls, ceilings, insulation and electrical systems.
- Wind: High winds can lift shingles' edges (or other roofing materials) and force water and debris underneath them. Extremely high winds can cause extensive damage.
- SnowandIce: Melting snow often refreezes at a roof's overhang where the surface is cooler, forming an ice dam. This blocks proper drainage into the gutter. Water backs up under the shingles (or other roofing materials) and seeps into the interior. During the early melt stages, gutters and downspouts can be the first to fill with ice and be damaged beyond repair or even torn off a house or building.
- Condensation: Condensation can result from the buildup 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.
- Moss and algae: Moss can grow on moist wood shingles and shakes. Once it grows, moss holds even more moisture to a roof system's surface, causing rot. In addition, moss roots also can work their way into a wood deck and structure. Algae also grows in damp, shaded areas on wood or asphalt shingle roof systems. Besides creating a black-green stain, algae can retain moisture, causing rot and deterioration. Trees and bushes should be trimmed away from homes and buildings to eliminate damp, shaded areas, and gutters should be kept clean to ensure good drainage.
- Trees and Leaves: 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.
- Missing or Torn Shingles: 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. The problem is likely to spread - nearby shingles also are ripped easily or blown away. Missing or torn shingles should be replaced as soon as possible.
- Shingle Deterioration: When shingles are old and worn out, they curl, split and lose their waterproofing effectiveness. Weakened shingles easily are 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.
- Flashing Deterioration: Many apparent roof leaks really are 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.
