We had an excellent experience with Hoffman Weber for roof repair after a hail storm last summer. Our insurance company wanted to only do half of the roof but they provided the information needed to get the whole roof replaced. Our salesperson Alex Roeller even offered to help us move our deck furniture if we needed. That was above and beyond his job. Jane at customer service was so good at working with us as we worked with the insurance company to get our full reimbursement. The work was excellent and done in a timely way. Some of our neighbors still do not have their work done as now we are into winter. I highly recommend Hoffman Weber!

How are asphalt shingles rated for wind and impact resistance?

Traditional 3-tab shingles typically are rated to withstand 60-70 MPH wind. Four-tab architectural shingles usually are rated for 110 MPH wind. High-Wind shingles can withstand 130 MPH winds.

What could shorten or extend the life of an asphalt shingle roof?

Inadequate attic ventilation or excess moisture can deteriorate roof sheathing and shingles from below. Overhanging trees that drop debris and slow drying can lead to moss and mold that can deteriorate roofing. Walking on a roof in extremely hot or cold weather can damage shingles.

For maximum lifespan of an asphalt roof, keep the attic cool. Avoid walking on the roof on extremely hot days to avoid scuffing the surface. Remove debris and treat to aid drying and discourage mold growth.

Is it okay to install a new layer of asphalt shingles over an existing one?

It is best to remove old shingles before installing new ones. This enables inspection of the roof deck for rot, replacement of the ice and water membrane at the eaves and valleys, reduces weight on the roof structure, and ensures the new shingles lay flat.

If my home has older skylights, should they be replaced while re-roofing?

Skylights, especially those made with plastic, fail and leak over time. Skylights should be carefully inspected for failed seals, cracks, wood rot and faulting flashing before re-roofing and replaced if they are to last as long as the new roof.

Is roofing felt (tar paper) required under roofing shingles?

Roofing felt is required under asphalt shingle roofs.

Where must ice and water membrane be installed?

Ice and water membrane should be installed at valleys eaves and along gently sloped roofs. At eaves, it should be installed from the edge of the roof to 2-feet beyond the interior wall.

Is drip edge flashing required? What purpose does it serve?

Drip edge flashing helps to move water away from the roof and the trim boards below.

Is it better to finish a roof valley with metal or with shingles?

Either valley method is code approved. Because of the volume of water that flows down valleys from the opposite planes, a smooth metal valley flashing with a centerline ridge is most efficiency is durable. Water and ice membrane is installed so it extends 24-in. to both sides of the valley.

Which is better, a continuous ridge vent or a series of square vents?

Either type of vent is acceptable as long as they are paired with balanced soffit vents.

If I am considering installing or replacing gutters should they be installed before, during or after re-roofing?

Depending on how existing gutters are installed, they may need to be removed before re-roofing. New gutters are best installed after a new roof is installed. This prevents the gutters from becoming damaged while removing the old roof and installing the new one. Depending on the condition of the fascia board behind the gutters, the fascia may need to be replaced to ensure a solid mounting surface and effective weatherproofing.
