Our Top 8 Roofing FAQ's

In honor of National Roofing Week we are pleased to share with you our most frequently asked questions from homeowners who have received consultations. If you have a question that is not covered here, leave it in our comments section below and a trained specialist will address it!

Q: How do I know when my roof has failed?

A: The following may indicate that your roof needs replacing:

    • Missing, cracked or curling shingles
    • Blistering or peeling paint
    • Shingle, sheathing or siding decay
    • Leakage in the attic after heavy rains
    • Stains on interior walls or ceilings
    • Rotten fascia or soffit
    • Chimney leaks

Q: How long will it take to complete my roof?

A:   On average, it takes one to two days. The exceptions are roofs that are larger than average, roofs that need extensive structural repairs, or roofs that require specialty materials.

  • We arrive on each job site with the manpower, expertise and materials to complete the job in a timely manner. However we will never compromise quality to complete a job more quickly.
  • Commercial roofs do not have an average time frame due to many varying and complex requirements for commercial buildings. We’ll give you an expected time frame for completion as part of our written proposal. 

Q: How much does a new roof cost?

A: The cost of your roof will depend on its size, shape, slope and the type of material you choose to install. Different roofing materials provide different levels of protection and service life.

Q: I received several estimates to replace my asphalt shingle roof system and the prices vary greatly.

A: If one estimate seems much lower than the others and it sounds too good to be true, it probably is. Many fly-by-night contractors' below-cost bids seem attractive, but these contractors often are uninsured and perform substandard work. If an estimate is confusing, ask the contractor to break down the estimate into items/terms you can understand.

Q: My contractor is offering a one-year warranty on my asphalt shingle roof system-is that the industry standard?

A: Before answering the question, a clarification needs to be made about the different warranties you will come across during your roofing project:


  • First, there will be the asphalt shingle manufacturer's warranty. In general, this warranty covers defects in the manufacture of the shingle. The period of coverage can range from 20 years to a lifetime. Once the project is complete, be sure the contractor provides you with a certificate for your records. 
  • Second, the roofing contractor will provide you with a warranty on his workmanship. Typically, this will cover installation and related issues. The warranty should contain what items are covered and what will void them. Many contractors offer one year or two years of coverage; however, there is no industry standard.

Q: How do I choose the right roofing company?

A: The right roofing company will be experienced, committed to quality, and have a trail of happy clients across the area. A quality contractor will always meet building codes and requirements and have strict standards for installers to adhere to. Make sure to get a detailed quote and research reviews & ratings from prior customers.

Q: Can I do roofing work myself?

A: Roofing work is generally not a DIY project. Professional roofing contractors are trained and benefit from years of experience to safely & effectively repair or replace your roof. An untrained homeowner can actually harm a roof with improper roofing techniques and could even harm themselves if the right tools & safety equipment are not used.

Simple maintenance tasks like inspecting a roof during the spring to look for broken or crack shingles & cleaning out gutters filled with debris are suitable for most homeowners but should still be done with care. Most DIY roofing projects end in additional costs & headaches for the homeowner, so they are best left to trained & experienced professional.

 Q.) How long will my roof system last?

A: Modern roofing systems are constructed to provide approximately 20 years of useful service life. A few types of roofs, mainly clay tile, slate, and copper, can actually last longer if regularly maintained. The life of your roof system will be determined by environmental conditions, proper installation & design, material quality, and adequate maintenance and repairs. Roofing material warranties can vary greatly so take a look at a manufacturer’s warranty programs before you decide.
