We had Tom Jannace Roofing install a new roof over 18 years ago. The roof had been problem free until recently when we noticed a small water leak coming from our sky lights. We called Tom and he was so polite, accommodating, and he actually remembered us. He repaired the leek and gave us an incredibly fair price for the new repair. If you are looking for a roofing company with old school values and quality combined with a professional and kind attitude look no further.i would give 10 stars if I could!

Why Do You Need a New Roof?
Whether it’s age related wear, storm damage, rising energy bills or fading curb appeal, your roof’s condition directly affects your home’s safety, comfort and value. Explore these four core reasons to invest in a new roof before minor issues turn into major headaches.
Your roof is the crown of your home don’t let it drag down aesthetics or resale. Spot these issues:
- Faded, mismatched or stained shingles dull colors scream “aged.”
- Outdated style: Homebuyers notice when the roof no longer fits the era.
- Visible wear and tear broken lines or missing pieces erode buyer confidence.
- Clashing rooflines: An unkempt silhouette distracts from your home’s best features.
- Sagging areas or dips: Structural weakness shows through and signals aging from beneath.
- Moss or algae streak: Organic buildup hints at poor ventilation and long-term neglect.
In minutes, heavy winds and hail can shatter your roof’s integrity. Look out for:
- Ripped shingles: Watch for debris in your yard after a storm.
- Exposed underlayment: Visible felt means water can seep in fast.
- Cracked flashing: Vulnerable spots around vents or chimneys.
- Hairline fractures: Often hidden in valleys and joints.
- Gutter overflow: Backed up gutters can push water under your roofline, causing rot and leaks.
- Loose nails or fasteners: Lifted shingles leave open paths for wind-driven rain and future damage.
- Water stains on ceilings: Leaks from storm damage often show up as brown spots inside your home.
A worn roof silently drains your HVAC budget. Key warning signs:
- Blocked or missing vents: Trapped attic heat forces your AC to work overtime, spiking your energy bills during hot months.
- Insulation gaps under shingles: Cold air escapes in winter while summer heat seeps in, making your HVAC work twice as hard.
- Cracked decking or underlayment: Creases and tears in the base layer let conditioned air slip out through the roof.
- Uneven upstairs temperatures: If one room’s freezing and another’s hot, your roof may be the problem.
- Light peeking through the attic: Even small openings mean big losses in insulation and air control.
Your roof is the first thing buyers and neighbors notice.
- Cracked, curling or missing shingles are a clear sign your roof’s first line of defense is failing and needs attention
- Granule erosion leaves your shingles exposed, causing faster wear and weakening the roof over time
- Sagging or springy decking underfoot can indicate hidden wood rot or long term moisture damage beneath the surface
- Hairline leaks may seem minor but can lead to costly structural repairs if ignored
- Faded or discolored shingles dull your home’s appearance and reduce its visual appeal from the street

If I could give more than 5 stars, I would. Tom and his crew did a full roof replacement for us. His pricing was fair, his communication was excellent, and their workmanship was very professional. He was even able to improve our attic ventilation and correct a previous framing issue we had. The roof looks great and we could not be more satisfied with whole experience. Highly recommended!
