A new roof is a costly investment with practical and aesthetic implications – the roof is your home’s most important protection against rain, snow and natures elements. The roof can also significantly impact the appeal of your home in the eyes of potential buyers.

This guide will help you make an informed decision when it comes to re-roofing (adding a new layer of roofing to the existing roof) or removing and replacing the old roof.
Seven Signs You Need a New Roof
Here are the indicators that your roof should be re-shingled or replaced to maintain your home’s defense against the elements:
Shingles are visibly worn: Are there so many of the colored granules gone that your roof looks like it has bald spots? While the shingles might still be keeping moisture out, a lack of reflective granules allows excess heat into your home, raising the temperature inside your house and increasing your air conditioning costs. Furthermore, once exposed, the underlying asphalt will soon dry out and crack, and then your roof will be susceptible to leaks.
Shingles are cupped and curled:
Curled-up old shingles
This issue looks bad, but more importantly, it means wind-driven moisture can easily get under the shingles and into your roof deck where it might cause leaks and rot.
Shingles are cracked: The cracked areas aren’t keeping moisture off the deck, and the risk of leaks goes way up.
Your neighbors are getting new roofs: This is more than “keeping up with the Joneses.” When homes built about the same time as yours are being re-roofed, your roof is probably about due.
You’ve experienced multiple leaks: Your roof is an entire structure, not just the shingles. Deck paper, flashing, moisture barrier in valleys, starter shingles, vent stack boots and other components are part of an entire roofing system. As the roof ages and several of its components or locations fail, the roof should be replaced.
The roof has experienced major damage:

If more than about 35% of your roof is going to need repair due to wind or hail, especially if it’s already 12+ years old, the cost-effective decision might be to replace it all.
Repair is costlier on a per square foot basis because it is more time-consuming to integrate new shingles into a roof “here and there” than to install them over the entire roof. Plus, a mix of old shingles and new just won’t look very good.
Your roof looks bad: Cosmetics and aesthetics do matter to homeowners and potential buyers. If your roof is worn, has algae staining that won’t clean up or has patches of moss on it, boosting its appearance with a new layer of shingles will make a very nice difference.

If none of these reasons to get a new roof apply, then you’re probably done here! If you’re not sure about your roof’s condition, hiring a home inspector or roofing contractor to inspect it can be a preventative measure before a roof failure and the extensive and expensive damage it can cause.

Types of Roofing Materials
The most common roofing options presented below cover more than 95 percent of all residential roofs in the United States, so unless you’ve got something unusual in mind like BiPV solar tiles – oh, wait, we’ve included those – or a vegetative green roof, the options you’re considering are likely discussed below.
More than 75 percent of all single-family homes in the US are roofed with asphalt shingles, though that number is slowly shrinking thanks to the more energy-efficient and durable metal roofing.
Asphalt (composition) shingles dominate the market because they are affordable, offer a variety of attractive options, and do a good job protecting homes from the nature’s elements.
There are two main types of asphalt shingles:
Fiberglass shingles start with a fiberglass mesh mat that is covered in asphalt and topped with granules that provide color and reflect some of the sunlight. Shingles made with fiberglass are lightweight and resist tearing.
Organic asphalt shingles begin with paper, often recycled, that is saturated in asphalt and covered with granules. The shingles are heavier and harder to work with than fiberglass, but they generally offer better stability in high winds. Although you can still see them on many roofs, organic shingles have been mostly phased out or discontinued over the course of last decade. Why? Manufactures have stopped making organic shingles due to their tendency to dry out, become less-waterproof and more prone to excess moisture absorption.
Pros and Cons of Asphalt Shingles
The reasons to choose asphalt shingles are:
Fiberglass shingles offer good fire protection
Look good on most any style home
Shingles are often the most affordable roofing option, especially in good/better ranges
The best asphalt shingles are a 30-year roof solution installed on homes located in moderate climates
The cheapest 3-tab shingles are an affordable way to dress up a home before putting on the market
Broad selection of colors and styles including affordable three-tab and architectural shingles that mimic shakes and slate
CertainTeed’s large selection of available asphalt shingle products includes the most luxury roofing shingle lines of any brand, plus the mid-grade architectural or dimensional shingles, and the basic 3-tab or strip shingles.
CertainTeed’s Grand Manor and Presidential Shake products are prime examples of Premium roofing shingles that have enhanced depth and differentiated appearance.
CertainTeed’s Landmark PRO roofing shingles are an example of a traditional architectural shingle designed to appear fuller and more dimensional compared to the flattish-looking 3-tab shingle. Dimensional shingles are also thicker and heavier than the basic 3-tab strip shingles.
Did you know? CertainTeed is a heavyweight brand – literally. Its shingles contain more asphalt than most.
CertainTeed shingles, even the 3-tab strip shingles, weigh 200-plus pounds per square. Most weigh 250-480lbs per square. More weight means better durability (and impact resistance).
Other brands’ shingles weigh 160-280lbs per roofing square.
But what about the price? It’s not a secret that all, CertainTeed is the most expensive brand overall. It sometimes denies warranty claims, though that’s a common complaint about all shingle brands.
Are CertainTeed Shingles Your Best Shingle Option?
Anyone researching shingles will find a lot of praise for CertainTeed roofing, along with a few horror stories.
This in-depth review provides unbiased information to help you make a well-educated buying decision.
