How long should a roof last?

Like any building component, roofs degrade at different rates depending on a large number of factors: the quality of original construction, the level of abuse, the level of maintenance, appropriateness of design, etc. So how long should a roof last? We have seen poorly designed and installed roofs go as few as seven to ten years before they failed, and we have seen old asphalt roofs that were over 30 years old. Most building owners, roofing contractors, and designers feel 25 years is an acceptable service life for today’s products. Read More

What is a 3-TAB shingle? An architectural (or dimensional) shingle? A designer shingle?

3-TAB shingles are the least expensive and most simple. They are single layer and give the roof a flat look.

Architectural shingles have an attractive appearance with a dimensional, more textured effect. They are heavier and thicker than 3-tab shingles, promoting longer life and extended durability.

There are a countless number of designer styles of shingles. Although these shingles may be a little more expensive, they also have increased value, beauty, protection, and longevity, and a more unusual and elaborate designs. Read More

How will I know when it’s time to replace my roof?

There are a few ways to determine if it’s time to replace your roofing system.
Age: Roofing systems generally last around 2 decades. If your roof is approaching 20 years of age, it’s near the end of its useful life.

Leaks: If you see evidence of water leaking inside to your home, it probably has been leaking for quite a while. Water can damage rafters, plywood sheathing, ceilings, walls and more. Extensive structural damage can create a huge problem for homeowners. It’s often cheaper and less involved to simply replace the roof before it begins to leak.

Appearance: Shingles that have begun to curl, break, or warp are a good indication that it’s time for a reroofing service. Read More

How Can I Find the Exact Location of a Leak?

Leaks can be tough to spot because water wants to find the path of least resistance and can travel for a while before finally showing up through your ceiling.
