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.
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.
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.
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.
Roofing felt is required under asphalt shingle roofs.
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.
Drip edge flashing helps to move water away from the roof and the trim boards below.
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.
Either type of vent is acceptable as long as they are paired with balanced soffit vents.
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.
