Your roof is a series of components that work together. We can tell you as much or as little as you want to know about roofing components. Our experience helps us know how to protect your home from accidental damage during remodeling. We thoroughly inspect your roof including flashing chimney, soil stacks, other roof penetrations, deck, and attic. We check existing ventilation for proper circulation. This is important because improper ventilation will damage your shingles and can invalidate your manufacturer’s warranty and cause problems with humidity and mold. We apply additional waterproofing underlayment to the wood deck if needed due to conditions of ice damming, wind-driven rain, or collected or flowing water.

Expert Installation
Shingles are applied according to manufacturer’s specifications with proper fastening techniques. That means four fasteners for each shingle – six in high wind areas. Fasteners penetrate 3/4″ into the deck.
Before & After Inspection
We supervise the job during all phases of work and inspect it completely when finished. We’re not finished until we thoroughly clean up your roof and around your house, remove all surplus material and leave your yard in the same shape than when we started the project.
When to consider re-roofing?
We only use quality name brand roofing materials with proper UL fire and wind resistance ratings
A leak(s), of course, is the most obvious clue that your roof needs some attention. Leaks can be caused by a variety of reasons, including ice dams, shingle blow-off or improperly installed or deteriorated flashing. Don’t just look for a drip coming from the ceiling, though. Signs of moisture also include discolored spots on the wall, loose wallpaper, peeling paint on the ceiling or a damp smell in a hallway or room.
Even if you’re not experiencing specific problems, you might decide to re-roof your home. Maybe a neighbor’s re-roofing job has impressed you, or maybe you’re simply trying to give your house a face-lift. When CertainTeed introduced laminated shingles in the 1960s, we ushered in the concept of roofing as a design element versus protection only. Add a dimensional look to your roof through the use of layering, shadow lines or intricate blends of colors. Or, achieve the look of natural slate or wood shakes.
If your roof shingles are falling apart or missing in this area, it’s a definite sign you need a new roof. Valleys are one of the most important areas of your roof. Snow and rain flow through valleys and into gutters. If the valley is compromised, you could be susceptible to roof leaks.
Repeated exposure to ice dams can damage your home permanently. Build-ups of ice and snow at the eaves, ice dams are formed when escaping attic heat melts snow at the ridge or peak of the roof. The meltwater seeps down the roof under the snow and refreezes at the eaves, which are colder. Some of the trapped water can seep through the roof, damaging shingles, the roof deck, even your home’s interior.
Shingles that are curled or buckling is a good sign that you may need a new roof. Look at the slopes of your home that get direct sunlight and if you notice the shingles are curling and losing granules, it could mean the shingles are past their life expectancy. There could also be a possibility that the roof is defective
Look in your gutters to see whether they are loaded up with shingle granules. Roofs tend to lose more granules toward the end of their life cycle. Inconsistant or darker color on some parts of the roof is another sign the granules have worn away.
