Roof replacement

How to know that you need a new roof

Leaking – If you have a two story house and you find yellow water marks on your second floor ceiling or on your one story house ceiling it means your roof is not doing its job and needs to be fixed!

Shingles cupping or curling – (asphalt shingles) This can only be explained with a picture (see photo at right). Again, water can get under the shingles and cause leaks, material deterioration or mold.

Attic inspection – Inspecting the attic is a great way to learn about your roof. You do not want to see any light peeking through or discoloration on the rafters.

Types of roofing

There are many kinds of roofing that you can choose from. A little information first: a "square" in roofing terminology is a 10-foot by 10-foot section of roof. Roofers determine this by calculation, and always add a certain percentage for cutting and replacement. The type you pick is based on your personal tastes, house style, and climate.
