  • What can I do about mildew on my roof?

    • Most home improvement stores sell a mildew cleaner that can be applied to your roof with a sprayer. Mildew cleaners shouldn’t damage your roof in any way.

  • How often should I clean my gutters?

    • Gutters should be cleaned at least once in the summer and twice in the fall.

  • Can heavy snow damage my roof?

    • Yes! It is important to keep heavy snow off your eavesdrops and cleared out of your ridge vents.​​​​

  • How long does it take to replace a roof?

    • Replacing a roof, whether on a commercial or residential building, is a labor-intensive project and, but most residential roofs only take one day. The time involved is substantially affected by the weather, as well. Wind, snow, rain, or even just the threat of one of these and will slow the process considerably.

    • For built-up roofs, removing and replacing the roof will probably proceed at a rate of approximately 1,500 square feet per day. For single-ply roofs, the rate is closer to 2,000 to 4,000 square feet per day. Careful planning and close project management can reduce some of the delays caused by bad weather.

  • Can I replace missing and damaged tiles or shingles without calling a roofing contractor?

    • It is always recommended that you use a professional, but in case of an emergency, it is possible for you to replace the shingle or broken tile yourself. (See how below.)

Composition Shingle Replacement:​

  • For composition shingles, roofing cement can be used to repair torn or curled shingles. Stabilize repaired shingles with nails or a heavy board until the cement has dried.To replace a composition, carefully lift the shingle above the missing shingle, then trim and place the new shingle underneath so that it doesn’t catch on any edges (it may be necessary to remove excess staples or nails). Carefully nail the new shingle into place.

Wood Shingles or Shakes Replacement:

  • For wood shingles, repairs are best done with an aluminum piece that can be slid under the shingle. This should protect the exposed area, while not being visible from below.

  • To replace a wood shingle requires a special tool, a shingle ripper, to slip under the shingle and hook and cut the nail. The nail can also be cut with a hacksaw, but is difficult to do. Slip the new shingle into position, but leave it ¼ inch longer than the other shingles. Then nail it into place right below the end of the overlapping shingle above. Finally, with a block of wood against the shingle butt, drive it up the last ¼ inch to bend the nails under the shingle above.

Tile Replacement:

  • To replace a tile, remove all of the broken pieces, then gently lift the tiles and slide the new tile into place until it hooks over the batten.

  • What is an ice dam?

    • Ice dams occur when snow melts near the ridgelines of warm roofs (roofs without adequate ventilation). As the water runs down the roof to the overhang, it cools and freezes. If the snow continues this melt and freeze process, an ice dam can form that can seep under the shingles, through the decking and into the house. This, of course, can cause serious roof leaks–even in freezing temperatures.

    • The best prevention to ice dams is a well-ventilated (cool) roof. Additional protection for your roof can be applied with an impermeable ice and water membrane. The membrane is installed on top of the decking, under the roofing material.

    • Temporary prevention of ice dams can also be done through the use of electric cables along the eaves of the roof (where the dams usually form). However, new ice dams can form above the cables and still cause extensive damage. Another emergency solution to ice dams is to fill a sock or nylon with calcium chloride. Lay the stocking vertically across the ice dam. The calcium chloride will melt the ice and release the water so that it can drain outside, and not inside your home.

Insurance Work FAQ’s

  • How long will the process take?

    • The entire roofing process should take between 1 and 2 days. This includes everything from tear off to final finish inspection.

  • Do I need to get an estimate before contacting my insurance company?

    • The insurance company dictates the price of the project. Regardless of the initial estimate amount, the insurance company will only pay out what it deems the cost of the project to be.

  • What if the insurance company’s coverage is less than my estimate? Will I have to pay the difference out of pocket?

    • The homeowner would only have to pay additional money if: 1) they wanted work done that the insurance company was not covering 2) If they wanted to upgrade to a product more expensive than what the insurance was covering.

  • Do I need to be home when the work is done?

    • No. As a matter of fact, many people plan to leave the property so they don’t have to deal with the “racket” or see the emotional process of demolition.

  • Will your crews clean up?

    • Yes. Or professional crews will work to keep your property clean during the project and after work is complete, the property is inspected and any loose debris and nails are removed.


  • Will my premiums go up if I file an insurance claim?

    • Premiums only go up based on zip code, so yes, premiums are going to go up after time from the number of claims in a zip code. Hail and wind claims are considered “acts of God” and people are not individually effected
