Q. Can a new roof be installed on my home during the winter?
A. Yes, Accurate Roofing can install a new roof during the winter, even when you have snow or ice on your roof. Our roofing crew will shovel and sweep the roof to clear and prepare it before proceeding with our normal roofing installation process.
If you are in an area prone to high winds, we will manually tar the shingles down as cold weather slows the sealing process. If your home is in a more sheltered area where the wind is minimal, we will allow the shingles to seal by themselves, which can take a couple of months.
At accurate Roofing, we 6-nail our shingles all year round to achieve the maximum wind warranty. IKO now offers a new type of shingle that comes in 7 unique colours, and has a reinforced mesh nailing strip for maximum wind resistance during storms. These IKO “Dynasty” shingles only cost an additional $1.10 more per bundle for a hurricane resistant shingle. The average residential roofing project requires about 45 bundles, therefore for an extra $50 you get hurricane resistant shingles in your choice of 7 unique colors.
Q. How will I know when my roof needs to be replaced?
A. You can use binoculars to check the state of your roofing without risking any injuries. Some things to look for are dark or black areas where granules have worn off over time, curling around the edges and tips of the shingles, and cracks in the asphalt mat which ice can infiltrate and expand, causing them to widen each year. You can also look in your attic for pinhole light spots around venting and other penetrations.
Q. Why do roofers use tar paper or synthetic underlays?
A. Tar paper is installed over the roof sheathing to prevent sap from the wood from absorbing into the shingles and breaking down the asphalt mat on the shingle. In addition, tar paper adds an extra layer of water resistant protection for your home if a shingle were to blow off in a storm.
Most roofing companies apply a synthetic underlay because it goes on faster and is easier to work with. However, tar paper is intended for use above cathedral ceilings when there is no air space, and synthetic underlays should be used over roofs with air space.
Q. How much ventilation is required for my roof?
A. Ventilation is an essential component of your roofing system. Roof venting allows the heat build-up in your attic to escape in the summer. During the winter months, venting helps keep your attic at a consistent temperature, preventing condensation on your roof sheathing that can lead to mold, mildew, and rot over time. A standard roof requires a minimum of 1 square foot of ridge venting and soffit for every 300 square feet of attic space. Following these guidelines accurately is essential for warranty purposes. Failing to follow these rules could void the warranty on your shingles. Accurate Roofing can offer optimal alternatives for ridge vent ventilation using materials which actually exceed the industry standards.
Q. What causes frost to form on my roof sheathing / nails?
Frost forming on your roof sheathing or nails is caused by an insulation or ventilation problem. This issue can usually be resolved by air-sealing any light fixture boxes in the attic and vents and increasing inadequate attic insulation to at least R-40. We actually recommend insulation be a minimum R-50 for proper ventilation. Your bathroom and kitchen fans should be used as often as needed to lower moisture levels in your home. If your Truro area home needs more insulation or ventilation, please give us a call- we offer ventilation services and blown-in insulation.
Q. How can I prevent ice dams from occurring?
A. Ice dams are caused by lack of insulation and poor ventilation. Heat from inside your home rises into the attic without insulation to stop it, causing the snow on the roof to melt. This melted snow runs down the roof to the overhang and freezes in cold weather, building up and creating a dam. The water will then accumulate against the built up ice, creating a pool. When the depth of this water exceeds 2 inches, it will back up behind and under the shingles and into your home. Ice dams can also be caused by extreme temperature fluctuations over a very short time period.
Q. What kind of roofing warranty do you offer?
There is a Limited Lifetime manufacturer’s warranty on metal roofing, and 10 - 25 years on other roofing products. We offer a 10 year workmanship warranty on our installation. If a shingle were to blow off or a leak to occur, we will come back and repair it free of charge.
Some manufacturer’s warranties and installation warranties vary depending on the products used and the slope of the roof they are installed on. Contact us for more details on our warranties.
Q. What are heating cables?
A. Heating cables can be an inexpensive fix for ice dam problems, as well as in situations when the weather fluctuates between high and low temperatures over a short period of time. Heating cables create channels to direct water into the gutters rather than pooling behind an ice dam. They also prevent water from melted ice from flowing over your gutter onto your sidewalk, where it can re-freeze and cause a safety hazard. Proper roofing ventilation should eliminate most risks of ice dams, however we do offer maintenance services as well.
Q. Do you do chimney work?
A. Accurate Roofing does offer chimney repair and maintenance services, including new lead flashing, brick replacement, re-pointing, installing new flues, and pouring a new chimney cap with an expansion joint.
Unlike most other roofing companies, we apply lead supplement to prolong the life of the lead and prevent staining on your new roof.
Q. Can new roof sheathing be installed over top of barn boards?
A. Installing shingles directly over barn boards or ship lap is never recommended. These boards are rough cut lumber, usually installed on homes 50-100 years old, and tend to be different sizes and thicknesses. Installing shingles over barn boards can cause stress marks in the shingles where the gaps and different thicknesses of boards occur. This can cause premature wear and shingle failure. We recommend installing new sheathing over the boards to give an even, uniform surface for installation of the shingles. Installation over tight tung and groove boards shouldn't cause any issues if they are in good condition.
Q. Does your company install skylights?
A. Yes, we offer several different skylight options. We suggest "sun tunnels" instead of skylights on larger sloped roofs where the attic roof is high up. Sun tunnels are less material and labor intensive than skylights, and look great on steep roofs. Skylights require framing, insulating, drywalling, air sealing, and a vapor barrier.
Q. My attic needs insulation, can you take care of that as well?
A. Yes, Accurate Roofing provides professional blown-in insulation services in addition to roofing in the Truro region. Our expert team will also ensure any attic vents and light fixtures are air tight. The minimum insulation standard for attics is R-40 but we highly recommend at least R-50 for energy efficiency.
Q. How often should I get my roof inspected?
A. Your roof may require work if any of the following apply to you:
If you answered yes to any of these questions, it’s time to call Accurate Roofing. Don't put it off until it's too late- once water penetrates your roof deck and finds its way inside, the cost to repair any damages can triple.
