ROOFING 101

2.EAVE PROTECTION

Considerable damage can be caused to the roof deck, along the eaves, when ice builds up during winter freeze/thaw cycle. Felt paper or waterproofing membrane is used on the deck to protect the deck from water penetration.

3.DRIP EDGE

Drip edge is a metal flashing, which is installed along the edge of the roof deck at the eaves. Its purpose is to divert water into the eaves and protect the wood deck from rot.

4.FELT UNDERLAYMENT

Felt underlayment is installed on the roof deck, under the new shingles, to shed water that is driven under the shingles. It is a second line of defense. Asphalt Shingles are intended to shed water not to seal the roof.

5.VALLEY TREATMENT 

The valleys on your roof are the most critical areas of the roof. The need extra protection. They can be metal or closed with an ice and water shield under the shingles.

6.FLASHING CHIMNEYS & DORMERS

7.VENTILATION

Air venting is very important and often overlooked.

8.PREMIUM SHINGLES

Shingle warranties are based on the weight of the shingles per 100 sq.ft.of coverage. We suggest a minimum of 233lb per sq. weight shingle for a premium roof.
