How do I know if I need a new roof?
The following are things that may indicate that your roof needs replacing:

  • Missing, cracked or curling shingles
  • Shingle, sheathing or siding decay

How long does it take to replace a roof?
The time required to replace a roof depends on the size, type and difficulty of the roof and can take anywhere from a few days to more than a week. The time involved is substantially affected by the weather as well as the number of inspections required by the city.  Before we begin each job we advise the client on how long we expect the job to last.

What happens if it rains on the day you're scheduled to work on my home?
The work is rescheduled for the next business day on which there is no rain. We pay close attention to weather forecasts and do not do any tear-offs on any day that has a chance of rain.

Can I apply new shingles over existing shingles?
Yes. You can apply new shingles over existing shingles, but it depends on the condition of the roof and city ordinance. If the roof has one layer of shingles that are laying flat and the deck is in good condition, the existing shingles typically do not have to be removed. Check with local officials to make sure that building codes are being followed.

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 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.

  • 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.
