What Should I Consider When Hiring a Maryland Licensed & Insured Roofer?

Don't hire an amateur for roofing repair, maintenance or installation. Insist on seeing evidence of Maryland Home Improvement Commission (MHIC) license. You can check license data at Maryland DLLR.Various municipalities and counties in Maryland also require roofing contractors to be licensed.

  • In order to get an accurate estimate, make sure proposals are broken down into separate line items.

  • For roof replacement, important items include type of roof covering, manufacturer and color, type of underlayment, replacement of existing roof, underlay and ventilation and flashing if applicable.

  • Does the estimate include cost of pulling permit?

  • Who pays if there is damage to landscape or other parts of the property?

  • Insist on approximate start and completion dates.

  • What specifically does the warranty cover?

  • Who will be in charge of the project?

  • How many workers will your roofer use?


  • Once you have established the specs for your roof replacement or roof repair, have qualified contractors bid on the same specs. The cheapest contractor isnt always the best value. Check references.

    My Roof is Leaking - Reroof, Re-cover, Patch or New Roof?

    A professional Maryland Roofing Contractor will advise you on whether it makes sense to just patch the roof, re-cover the roof also called reroof - or replace the roofing system.

  • Patching is usually appropriate if the roofing system is mostly intact.

  • Reroof is sometimes an option but if there has already been a reroof, many building code requirements will forbid a second reroof.


  • Discuss the options with a qualified and insured Maryland Roofing Contractor.

    Pros and Cons of the 6 Basic Types of Roofing Material in Maryland

    1. Asphalt Shingles are the least expensive per square (a square is 100 square feet.)

    2. Wood Shingles and shakes cost a little more and typically have longer life spans. If not treated with fire retardant treatment, wood shingles and shakes have Class C fire ratings or no fire rating.

    3. Clay Tiles are typically more expensive per roofing per square than Asphalt or Wood Shingles but even more durable and heavier.

    4. Various types of Slate Roofing are often the most expensive and most durable alternative. Projected life spans run as high as 100 years. Not only is slate roofing material more expensive but application requires greater skill and costs more.

    5. Metal roofs run a range of prices. Life spans also range depending on variables. Aluminum, coated steels and copper roofs are becoming more popular. Metal roofs are very light an advantage.

    6. Concrete shingles and other roof products made from concrete like concrete panels and lightweight tiles are expensive but have long life span.

    Why Should I Hire Only a Licensed & Insured Maryland Roofing Contractor?

    Damage or injury caused by a non-licensed roofer can result in denial of coverage. And roof installation, maintenance and repair are dangerous. OSHA reports that 115,000 injuries occur due to falls in construction each year. Workers Compensation due to these falls runs about $718 million. Roofing Contractors bear the brunt of many of those injuries. Make sure not to hire an uninsured Maryland roofer you dont want to be liable.
