Q. How much does a new roof cost?
A. There is no definitive answer. Before an estimate can be made, considerations include type of materials, measurements, and the pitch of the roof. You may only need a repair to your existing roof.
Q. How do I know if I need a new roof?
A. Roofs usually last 20 to 30 years, unless special materials and installation techniques were used. Replacement is usually indicated if shingles are blistered, torn missing and/or splitting. If the roof is leaking, it may only need a repair to a specific area of the roof.
Q. I just had construction done and want to install the roof underlayment. What if it rains on this material?
A. This won’t matter as long as you install shingles in the very near future. If you are using standard tar paper and it gets rained on, you will notice some buckle.
Q. What is gravel stop and metal edge strip? What is its function?
A. The primary function of gravel stops and metal roof edge strips is to close off the edges of the roof to prevent wind damage or blow-offs. Another important function of gravel stops is to prevent the loss of aggregate surfacing near the edge of the roof.
The principal problems with gravel stops and metal edge strips are leakage through open or broken joints between metal pieces, and splitting of the stripping felts at metal edges. For these reasons, gravel stops and metals edge strips should be raised out the water line whenever possible by using raised wood nailers and tapered edge strips. The use of interior drainage is preferred. However, where water must drain over the metal edge, scupper cutouts are preferable to continuous edge drainage.
