OUR RESIDENTIAL ROOFING SERVICES
Grennan Construction has proven to be a leader within the residential roofing company industry, serving with integrity while offering a range of residential roofing and siding services that meet your needs.
PREMIUM SHINGLED ROOFING
When a roof can account for as much as 40% of the average home’s exterior, many factors weigh into the choice of materials. Some surfaces are more beautiful than others. Some offer greater resilience or endurance. Some are more affordable. But the one roofing surface which offers all those attributes in balance is the asphalt shingle.
Now accounting for about 80% of the residential roof surfacing in the United States, asphalt shingles are measured against a variety of standards that evaluate fire and wind resistance, tear strength, and other key performance indicators.
Asphalt shingles have a glass fiber reinforcing mat manufactured to the shape of the shingle. This mat is then coated with asphalt which contains mineral fillers. The glass fiber mat is not waterproof by itself. Its purpose is for reinforcement. What makes the glass fiber shingle waterproof is the asphalt. However, the asphalt itself will not stick to the mat. For this reason, “fillers” are used. The fillers in the asphalt cling to the glass fibers in the mat. The asphalt then encapsulates the glass fibers, fills all of the little holes and voids in the mat rendering it waterproof. After this cools a bit, adhesive asphalt is used to cover the mat and the ceramic granules are then embedded.
Grennan Construction is proud to install shingles from only the highest-quality manufacturers – such as CertainTeed, GAF and Owens Corning. When your roof is on the line – only the best will do.
PROTECT YOUR HOME
The ceramic granules are there for two reasons. The primary reason is to protect the shingles from the sun. The sun’s UV rays are very damaging to asphalt and cause it to deteriorate prematurely. This is one of the reasons that gravel is used on built-up roofs. The second and more obvious reason for the granules is aesthetics. Asphalt shingles are available in a wide variety of colors to match almost any facade or landscape.

When is it time to get a new roof?
Here are some of the tell-tale signs that it is time to call Grennan Construction to talk about new residential roofing:
Leakage in attic after wind-driven rain
Possible causes: Leaky or inadequate shingle underlayment or deteriorated flashing
Leakage in attic after ice build-up
Possible causes: Inadequate shingle underlayment or inadequate attic ventilation
Blistering and/or peeling of interior and/or exterior paint
Possible causes: Excessive temperature or high humidity due to inadequate attic ventilation
Stains on interior ceilings and walls or mold and mildew growth
Possible causes: Inadequate or faulty shingle underlayment allowing leakage or inadequate attic ventilation
Proper attic ventilation is crucial to a long-lasting roof system. Poor attic ventilation can ruin your insulation, destroy your shingles, and raise your energy bills!
Most people think replacing their residential roof is simply replacing shingles. However, we want our customers to know better! Today, effective residential roofing relies on advanced material technology and an integrated systems approach to protect your biggest asset – your home.
Decay of roof shingles, sheathing, and/or siding
Possible cause: Inadequate attic ventilation
Missing, cracked or curled shingles
Possible cause: Shingles have reached the end of their useful life
Dark, “dirty-looking” areas on your roof
Possible causes: Environmental pollutants; vegetation, fungus or algae; loss of granules due to age of shingles
Excessive energy costs
Possible cause: Insufficient attic ventilationIn. In warm weather, inadequate ventilation will trap hot air in the attic, causing air conditioning systems to work harder, or leaving your home’s interior hotter and less comfortable. In both hot and cold weather, insufficient attic ventilation may cause moisture in the attic to become trapped and condense on the rafters. This condensed moisture can drip down onto the insulation and reduce its effectiveness. Excessive energy costs can result.
