When Choosing a Roofing Contractor & Roof Shingle or Covering Material be sure to consider

Photo: PJ Exteriors, Poughkeepsie, New York, a roofing and building exterior repair company, replacing a leaky EPDM roof in 2022. Photo by the editors.

The old roof was torn off along with its layer of insulating board; any sections of damaged plywood roof sheathing were replaced and the roof cavity inspected for wet insulation or hidden mold contamination before the job continued.

Some of these same workers had installed the EPDM roof on another wing of this building (lower right in this photo) twenty tears before, back in 2002. That roof was still in good condition twenty years later.

• Workmanship:
  
  the best assurance that your new roof will not leak and that it will have a long life is to select a quality shingle product and to be certain that the shingles are installed absolutely correctly - good workmanship is what makes a roof shed water.
  
  

• Shingle or other roof material quality:
  
  we would not hesitate to buy a good quality shingle product from any of the current roofing shingle manufacturers, including GAF, but
  
  
• Shingle installation standards:
  
  we would want to be sure that my installer applied them according to the best practices in the industry since otherwise any warranty will be voided anyway.
  
  The principal sources of asphalt shingle roofing installation standards are the National Roofing Contractors Association (NRCA's Roofing and Waterproofing Manual), and the Asphalt Roofing Manufacturer's Association (ARMA). There are also ASTM standards for roofing products.
  
  
• Roofing contractor reputation and experience:
  
  before hiring ANY roofing contractor, we would check with the local better business bureau and would ask for references from local customers of the contractor.
  
  
• Supervision during the roof shingle installation:
  
  we would want to be darn sure that the people actually doing the work are trained or at least supervised, continually, every day all day on the job, by a trained, experienced, roofing contractor.
  
  Too many roofing companies have a salesman or prime contractor who sells the job but sends untrained workers to put on the roof with minimal or no actual supervision.
  
  
• Maintain your roof:
  
  with your roofing contractor, discuss regular roof inspections, the condition of your under-roof or attic ventilation, and what special problem spots may be on your roof, and what to do about them.
  

STEP 1: How to Find a Roofer - Beginning a search for a roofing contractor

This means finding a roofing contractor who knows good roofing practices, roof flashing details, how to handle problem spots on building roofs, and alternative roof covering products: shingle types, grades, colors, low slope roofing, flat roofing materials, etc.

A competent roofer will provide you with sound advice on products, reasonable explanation of procedures, and, most importantly, solid results - no leaks, and a durable roof. It's difficult to determine the capabilities and reliability of a contractor.

For specific roofing types there are usually specialty industry & trade associations that can provide referrals to those roofing companies with suitable training and expertise, such as the following:

Any home improvement is a complex combination of elements, the success of which depends on the quality of materials, installation and overall construction.

There are many ways to start your search for the contractor who meets your individual needs. Referrals are obviously the best source for names of credible companies. Ask friends and family members who they have used in the past.

• Contact your local Chamber of Commerce about contractors who are active in the community.
• The Better Business Bureau, state and local licensing authorities, local trade associations and your local yellow page directory are also excellent sources of information.
• Local suppliers of building products often can point you to roofers in your area.

Readers should also see ROOFING CONTRACTOR CERTIFICATIONS for a simple basic outline of the key ingredients to a good roofing job and a long lasting roof.

STEP 2: How to Choose a Roofer: Meeting and Evaluating Potential Roofing Contractors

After you have compiled a list of possible contractors, take time to evaluate each one carefully. A professional contractor will be happy to provide any information you may require.

Many homeowners have been mystified by the seeming lack of interest and response from the contractors they call. To get a contractor to respond to your call, tell him you are shopping around, but are only interviewing three contractors, not ten.

A contractor is shopping for good jobs that will make a fair profit and bring future referrals . Many contractors have had experiences with unreasonable or dishonest homeowners. Therefore, they look for warning signs of customer problems during the initial job interview.

Set up a meeting to discuss your needs and their qualifications, and be sure to pay close attention to the attitude of the company representative. Good contractors take pride in their work and will be enthusiastic about the possibility of helping you with your problems.

If you feel confident that the contractor is truly interested in your project, ask for the company's vital statistics-specific business information which will help you make your final decision.

• Business Name and Address:
  
  A good, professional contractor will provide the telephone number. These are essential when checking on the company's previous business dealings.
• Experience:
  
  The training and experience of a contractor, as well as the age of his or her company, will help you determine their ability to successfully complete your project.
• Licensing/Bonding:
  
  Some states or provinces (Canada) require special licensing for contractors.
• Ask for business license numbers and information on the company which bonds the contractor.
  
  Then check with local authorities to see that the company compiles with regulations.
• Insurance Coverage:
  
  A contractor should carry worker's compensation and general liability insurance. Request the name and address of the insurance carrier, along with a copy of the company's insurance certificate.
  
  Beware of low bids which are a result of incomplete insurance coverage and workman's compensation.
• Professional References:
  
  Your contractor's past can help determine your future.
• Ask for credit references:
  
  References and a list of completed projects including the names and telephone numbers of previous clients.
• Company Philosophy:
  
  Discuss application techniques and workmanship guarantees.
• Does the contractor stand behind his work ?

Roof Repair Estimates vs Roof Inspection

Question: what is the difference between a roof inspection and a roof estimate?

One question: what is the difference between a roof inspection and a roof estimate. Do roof inspectors eventually do the work or are they totally independent?

Thank you the wonderful information regarding slate roofing.

(SLATE ROOF INSPECTION & REPAIR - home )

My family and I are assessing whether to buy a lovely 1812 Federal style house. Somewhere in 1860 they built an additional floor and a slate mansard roof. The house is located in Ossining, NY and the owners have never really replaced the slate roofing except for the very occasional slate here and there.

So for the most part the roof hasn't been touched or had any major work since 1860.

The attic has some signs of water damage, and the flooring and walls look like they have had severe issues with contracting and expanding so there is warping on the floors and severe cracks on the ceilings and window casings. Could you guys recommend a roofing expert/ inspector for a roof of this style and age near Ossining, NY?

OPINION: The difference between a roof repair estimate and a roof condition inspection depends on who does the inspection.

Home inspectors, professional roof inspectors, and roof inspectors who work for insurance settlements are not people who would do the repair work.

However there are also roofing contractors who will perform a paid roof inspection. It's typical for the contractor to offer that if you hire them they will credit the inspection cost against the cost of the repair

Obviously you want to avoid conflicting interests. For that reason, some professions such as home inspections actually prohibit the inspector from doing the work that the inspector said was needed. At least that was the professional standard of the model National inspection Association, ASHI, the American Society of home inspectors.

Not all home inspectors are equally qualified to perform roof inspections. In particular roof inspection for your roof needs to be by someone who has depth of experience in slate Roofing. Otherwise you're likely to get crazy advice.

When states begin to license home inspectors, so many contractors who wanted to be licensed objected to the ethical constraint that most states omitted requiring the avoidance of conflict of interest. So it's something you want to watch with care.

We can't make a specific contractor referral, both to avoid conflicts of interest and because more simply I don't have one. Even when I've found a good slate roof contractor, the work quality of what that contractor may provide later to someone else may vary a lot depending on the crew, supervision, and maybe other factors.

What we can do is discuss, when you have 2 or more bids, what you're being told and what prices are being offered. Often we can suggest questions to ask that help steer away from trouble.

BE SURE to use a contractor who specializes in slate. An asphalt roofer may bid the job and ruin the roof or make other mistakes.

If the roof really dates from 1860 there are plenty of questions to ask about the condition of slates, underlayment, slate fasteners, flashings on the roof, roof sheathing, roof framing. Don't let an idiot walk on the roof; inspect from attic, ground, and ladder at roof edges.

I like the tip that you gave to choose a roofing contractor who is experienced. My wife and I have been talking about finding a contractor to help us if we decide to replace our old shingles, and it would be important for us to know that we could find a trustworthy contractor.

If we decide to find a contractor, I will be sure to check their experience level beforehand.

After being left with a severely leaking roof by a shoddy contractor, my attorney warned me NEVER to sign a roofing contract with an arbitration clause. Cross out the clause, initial it, then sign....if the roofer will not accept this, get another roofer.

On 2017-03-31 by Kyle Winters & Cindy Tesler:

Thanks for the tip to make sure your shingles are being installed properly according to the best practices in the industry.

You also said that these principals come from the National Roofing Contractors Association. I think it's important to choose a roofer that has an online gallery of their other works so that you can get a better idea of what your finished roof will look like.

I like all of the things you list as important to look for in any roofing contractor. In particular, I like that you recommend finding a roofer with insurance coverage. After all, working on roofs is quite dangerous, so you want to make sure they're covered in case there is an accident.

We are looking at having our roof replaced simply because it is quite old and has some leaks.

Hopefully, a new roof will help improve energy efficiency in our home as well. It's definitely important to find a roofing contractor that you can trust. As you said, looking at their professional references is a good indicator of how they will perform according to past performance. Thanks for sharing!

My roof is in desperate need of repairs. A reputable contractor is important, and I agree that you should check a contractor in regards to the BBB. Something else to do is to get a roofing company that is affordable for you, so that you don't spend more than you have.

I need to get a new roof on my house and love the idea of setting up roof inspections so that your roof can stay in top condition.

I agree that you want to find a roofer that has a good reputation and has references. I'll have to make sure to follow your advice to help me get a good professional roofer.

It makes sense that the business you choose should have a lot of experience. That way you can be sure they know what they're doing and hopefully won't damage anything. My husband needs to find a roofing contractor, so I will make sure to have him ask about experience.
