Do I need a new roof?

                        There are many indicators that suggest you may need a new roof.                    
   
Shingle Roofs:   A persistent leak, mold, curling shingles, granuales in the gutter and near the leader on the ground, and flashing pulling away from the structure may indicate your roof system is failing or coming towards the end of its useful life. 


Commercial/Flat Roofs: Persistent leaks, mold, flashing pulling away from the perimeter, or near air conditioning and other penetrations on the roof, flashing that is lifting, splitting or cracking, seams are opening, or membrane deterioration where the coating is wearing away are all indicators your flat roof should be replaced.

Should I be concerned about curling shingles?

                        Curling shingles indicate that the oils  in the shinlge are starting to evaporate and the shingle is shrinking.  This shrinking may begin to expose the vulnerable plywood underneath. Continuous water exposeure can then deteriorate the wood decking causing a leak.

How much will a new roof cost?

                       The cost of a new roof is dependent on factors like the total labor, materials, amount of layers of old roof removal, and repairs to the underlying structure. Cheaper isn’t always better. When in doubt about the cost of a quality roofer, remember the motto "If you think it's expensive hiring a good roofer, try hiring a bad one." Please call to learn more about your options and how Nassau Roofers can effectively solve your roofing problem.                 

Can I place a new roof over my old one?

                       Installing a new shingle roof on top of the old one isn’t recommended. You may save money in the short run (because you don't have to pay for the labor and debris removal), but it will cost you more in the long run.  This os because not only will the life expectancy of your new roof be greatly reduced, you may spend more on energy costs. As a matter of fact, the life expectancy of your roof can be reduced by half and in most cases your warranty with the maunfaturer may not be honored.  Here’s why: The second roof layer causes your roof to lose air flow which causes the shingles to overheat and your home to retain a greater amount of heat, causing your air conditioning system to work harder.                      
   
           Please note:           New York State Building Code states a third roof can not be installed due to weight loads.                


Flat roofs have greater success with overlayment.  A core sample will typically be taken to indicate how many layers currently exist and whether the roof can bear an additional layer.       

How much insurance should my contractor have?

                       Your roofing contractor should have a $2-5 million liability policy and Worker’s Compensation for anyone that steps onto your roof. Beware, general contrators and smaller roofing contractors will save money by not carrying enough insurance. Their prices may be cheaper upfront, but if an injury occurs, your homeowner’s policy will have to cover the costs! If you don’t have enough coverage you can lose your home or business because you hired a contractor without sufficient insurance coverage.

How long should my roof last?

                        There is a large range of quality of workmanship and products in the roofing industry.
Poorly installed roofs can last as little as 10 years.
However, when you hire a ROOFING professional such as Nassau Roofers, our professional installers are fully skilled in every aspect of the materials, systems and process required so you can experience the greatest life expectancy for your roof.  We are confident this  will be the last time you need to worry about replacing your roof as we install LIFETIME WARRANTY shingles properly.    
           

Should I be concerned with granules in the gutter?

                        Asphalt shingles are covered with granules to reflect water and light to protect your home or business. Your asphalt shingles experience erosion from water, UV light and heat. UV light and heat dries the shingles out; water wears away at the granules, some of which have been loosened by heat and light. When granuales are consistently lost and you can begin to see them in your gutter or near the ground by your leader, your roof is deteriorating.       

I am considering having both roofing and siding installed. Which should I do first?

                       Your roof should be installed first. It is important to protect your home or business from the top down. 

What types of warranties are available?

                        In roofing, there are two types of warranties or guarantees, labor and material or material only. Labor and material warranty coverage is what you should look for. Labor and material warranties will cover your roof much better than just a material warranty only.  Nassau Roofers has been in business for over 40-years and offers very competitive labor guarantees.  Nassau Roofers will be your first point of contact should you have any trouble with your new roof.                   

What’s the difference between a contractor’s guarantee and a manufacturer’s warranty?

                        A Contractor’s Guarantee is good for only as long as the roofing contractor is in business. BEWARE of "fly by night" contractors.
Always ask how long the company has been in the roofing business. If the company goes out of business there’s no one to honor the guarantee, a very common problem as roofing is a high turnover industry.  Nassau Roofers is a 2nd generation, family-owner business since 1978, so we expect to be in business for MANY years to come!
   
     A Manufacturer’s Warranty is a joint agreement between the contractor and the manufacturer and Nassau Roofers offers shingles with various warranty lengths.  Please ask if you have questions regarding specific Manufacturer Warranties.    
              

How do I process a warranty claim?

                        Always contact Nassau Roofers first. The roofing contractor should act as the liaison between you and the manufacturer. A Manufacturer’s Warranty is a joint agreement between the contractor and the manufacturer for the first years of roof’s life depending on the type of roof put on. The contractor is responsible for any repairs during the initial guarantee period. After that time, the manufacturer is responsible for warranty issues that may arise.                                     

Should I be concerned if my roof has blisters?

                        A blistering roof should be evaluated as soon as possible. Blisters are usually caused by trapped moisture or a material defect in the asphalt shingle.                     

What is Ice Damming?

                       As snow melts and refreezes it begins to form an “ice dam” at the edge, or eave of a roof.  This stops further snow melt from draining properly into the gutters or other drainage system.  The warmth of the house, then causses the snow and ice to melt and back up under shingles near the ice dam, possibly causing a leak. This can also cause damage to your gutters.        

Do you need adequate Attic Venting?

                       Proper, adequate ventillation is iportant in your attic for a number of reasons.
Shingle manufacturers require attic ventilation in order for you to receive a manufacturer’s warranty.  In addition, building codes require it for the safety of your family and occupants.  Also, proper ventilation will allow your roof to “breathe”, cooling your home and extending the life of your roof.                     

What building codes impact my roof?

                        There are a few building codes that can affect your roof. Some of the more important are the number of layers (no more than 2 layers allowed), the thermal value for commercial buildings (must be rated R20), and the amount of insulation (at least 3 ¼ inches).                
   
     If you have concerns whether you're building’s roof is up to code, call Nassau Roofers at your earliest convenience for a consultation.          
         

What Causes Leaks?

                       The most common casues of roof leaks  are penetrations in the roof, such as: chimneys, vents, skylights, flashing, air conditioning units, etc. Usually this is due to errors in installation or materials wearing away with age. We make sure all areas of penetration are installed and water-proofed correctly. Flashing details are something expert roofers do very well, whereas novices or general contractor may not be proficient at flashing these penetrations on your roof.

Nassau Roofers is very good at identifying a leak and repairing it, because we are experts at spoting and solving these types of leaks.  

      Other times, leaks occur due to improper installation of shingles (shingles nailed too high or not enough nails).  Nassau Roofers  can also help to solve these types of leaks before you may be ready to replace your roof completely.


What will void my warranty?

                        Unauthorized penetration work (anything that penetrates the roof without the knowledge and assistance of the original roofing contractor; added vents, air conditioning units, solar panel installation etc.) and any materials stored on the roof. Please contact us if you have any questions concerning your warranty.                    

What are the benefits of roof maintenance?

                        It’s a large investment to replace a roof. Residential roofs can run between $4,000-20,000 plus depending on the size and materials. A commercial roof can easily be hundreds of thousands of dollars.                    
   
     A Residential Roof doesn’t usually require a lot of maintenance, and most can be done by the homeowner. Seasonally, removing debris from gutters is the usually all that is required. However, if you’re concerned about the condition of your roof, call Nassau Roofers for an inspection.
   
     A Commercial Roof will greatly benefit from annual inspections and maintenance. This will prolong the life of your roof investment because problems can be caught before they get worse.  In addition,  you may potentially avoid costly leaks that may damage the infrastructure, electrical equipment, furniture, and flooring—not to mention liability claims if a customer or occupant slips and falls.                    
   
     Maintenance visit includes checking to see if all the flashing details are in good condition, the drains are clear, any unwanted vegetation is removed, unwanted materials are removed (like balls, sticks, bottles), and the roof surface is not deteriorating.                      
   
     Please contact Nassau Roofers directly to discuss Commercial Warranty Plans as costs depend on square footage and the accessibility of the building.
