November in Maryland means dropping temperatures, frost-covered mornings, and the first threat of ice dams. Your roof faces its toughest season — and a small weakness now can become a major leak by January. At Home Pro Contractors, we help homeowners across Baltimore, Waldorf, Calvert County, St. Mary’s, Frederick, and all of Maryland prepare their roofs to keep the cold out and your family warm.
🔥 Pro Tip: A well-insulated, ventilated roof can reduce heating costs by up to 20% this winter.
How Maryland’s November Weather Affects Your Roof
- Frost & Ice Formation – Nighttime temps below 32°F cause shingles to contract, cracking seals.
- Ice Dams – Snow melts during the day, refreezes at night, and backs water under shingles.
- Wind Gusts (20–40 mph) – Loosen flashing and lift shingles in exposed areas like Dunkirk, Lusby, Leonardtown.
- High Humidity + Cold – Trapped attic moisture leads to mold and wood rot.

FAQ – Winter Roofing in Maryland
What causes ice dams on Maryland roofs?
Poor attic insulation causes heat to melt snow, which refreezes at the colder roof edge, forming a dam that traps water.
How much does ice dam prevention cost?
Ice & water shield: $1,200–$2,800. Heat cables: $600–$1,500. Full prevention package: $2,500–$5,000.
Can I install heat cables myself?
Not recommended. Improper installation risks fire or roof damage. We use UL-listed, self-regulating systems.
Do you offer emergency winter repairs?
Yes – 24/7 tarping and leak stops in Baltimore, Waldorf, Calvert, and all MD counties.
Will a new roof lower my heating bill?
Yes – proper insulation + ventilation reduces heat loss by 15–20%.
Are you licensed in all Maryland counties?
Yes – MHIC #116004 covers statewide residential and commercial work.
