Frequently Asked Questions
- Is it OK to cover an existing layer of shingles with a new layer on my home?
Even though many building codes says it's acceptable, we advise that you don't do it.
Why? Underneath shingles is a layer of wood sheathing, usually plywood. Sheathing can rot because of leaks, inadequate attic ventilation or just age. The best way to protect this critical layer is to strip away the old shingles
- Are all asphalt shingles the same?
Today's laminated and fiberglass-reinforced products are better than ever. Shingles are rated for durability. Some are warranted to last 50 years. We are certified by GAF Master Elite Roofing to offer limited lifetime warranties on their products.
- When does flashing need to be replaced?
Flashing, the metal material designed to divert water away from vents, pipes and other roof openings, can lie in place for years and protect your roof. As a rule, flashing should be checked every six months to make sure it is doing its job properly by protecting a perfectly sound roof. And should be changed when the roof is replaced, (never reuse metal flashing). Simply look for dried caulking or sealant, cracked or broken flashing pieces and damaged shingles in contact with the flashing.
- Does attic insulation save energy and help roof performance?
Adding more than the required installation can block ventilation openings at the soffits and eaves and might trap moisture. By having proper insulation you will eliminate moisture buildup and maintain steady attic temperatures in both cold and warm seasons.
Signs of inadequate ventilation are ice-damming, mold on the underside of the sheathing and excessive frost accumulation on the roof deck or in the attic.
- Are gutters separate from roofing system?
Roofs are designed to divert water from the structure. The gutters are the final piece of the process. They prevent water from dripping down exterior walls and move it from the foundation. It's why many roofing installations can include new gutters and downspouts.
