The best roofing underlayment depends on your roof's material and local climate. Generally, synthetic underlayment (like Owens Corning ProArmor or GAF FeltBuster) is the top choice for overall durability, walkability, and tear resistance. For vulnerable areas like valleys and eaves, self-adhered ice and water shields are essential.
Types of Roof Underlayment
The market offers three primary types: felt, rubberized asphalt, and synthetic. Each type has distinct characteristics and benefits: Felt Underlayment: This traditional option, also known as tar paper, is typically made from an organic or fiberglass base saturated with asphalt.
Flat or Low-Slope Roofs: Use 5/8-inch or 3/4-inch CDX or T&G plywood to handle pooling water and heavier roof loads. Steep-Pitched Roofs (Residential): 1/2-inch CDX or OSB works well with standard rafter spacing (16″ on center).
The 25% Rule in roofing serves as a guideline for both homeowners and contractors when planning roofing projects. Basically, it means that if more than 25% of your roof's surface needs repairs, it's often wiser to contemplate a full replacement rather than patchwork.
Generally, the late fall and winter months can be the most cost-effective times to schedule a roof replacement. This is typically the slow season for roofing contractors, and as business wanes, you might find that they are more willing to negotiate on price.
What damages the roof the most? Sun exposure, poor maintenance, and severe weather like hailstorms and strong winds do the most damage.
For a 2,000 square foot home with asphalt shingles, the installation typically takes 2-3 days, while the entire process from planning to completion usually spans 2-3 weeks.
Neutral and timeless roof colors like black, charcoal, gray, and brown consistently deliver the highest return on investment. These classic shades have universal appeal, seamlessly match nearly all architectural styles, and attract the widest pool of potential buyers.
To tell if a roofer is lying, watch out for high-pressure sales, suspiciously low bids, and demands for large upfront cash payments. Honest roofers provide clear, detailed contracts and verifiable credentials. Always check their local license, avoid signing contingency agreements before fully committing, and get a second opinion.
The best shingle brand depends on your priorities, but industry leaders consistently highlight CertainTeed, GAF, and Owens Corning for their longevity, warranties, and nationwide availability. For cutting-edge materials and eco-conscious options, Malarkey Roofing Products is highly recommended.
The butt seams of the plywood sheets should be staggered between courses for strength. So with each course, we alternate between using a full 4×8 sheet and a 4×4 half-sheet for the first piece.
Treated plywood generally lasts between 10 to 30 years outside, depending on its exposure, the type of treatment (e.g., above-ground vs. ground-contact), and how well it is maintained. Fully exposed sheets without maintenance may only last 5 to 10 years.
For most residential roofs, the standard minimum thickness for OSB (Oriented Strand Board) is 𝟕/𝟏𝟔 inch. However, depending on your truss spacing and local weather conditions, 𝟏/𝟐 inch or 𝟓/𝟖 inch is heavily recommended for better structural stability and resistance to sagging.
When Underlayment is Not Necessary for Laminate Flooring
A good quality underlayment resists water fairly well. The thicker and stiffer it is, the better and longer it can protect against the weather. There are many reasons an underlayment could fail including: Poor quality - Underlayment made with subpar materials can't keep water out effectively.
Yes, roof underlayment should go over the ridge. It is standard practice to run the underlayment up and over the peak of the roof, overlapping both adjacent roof planes by at least 444 to 666 inches. This ensures a continuous, shingle-lapped barrier against water intrusion at the highest point of the roof.
What Should You Not Say to a Contractor?
The national average cost to replace a 1,200 sq. ft. roof is $5,700 to $12,000, with most homeowners spending around $8,400 on architectural shingles installed on a cross gable roof. This project's low cost is $3,600 for 3-tab shingles installed on a gable roof.
Factors that decrease property value the most fall into three main categories: location issues, structural damage, and poor neighborhood conditions. These factors can collectively slash a property’s value by 5% to 30% or more.
Light-colored roofs, such as light gray, beige, white, or soft earth tones, make a house look larger and more expansive. These lighter shades prevent the roof from appearing heavy or overpowering, helping the structure appear taller and more inviting. They also reflect sunlight, offering increased energy efficiency.
If your roof is newer and made of durable materials, like metal or slate, your homeowners policy may cost less than if you have an older roof — which may be more susceptible to damage and a risk for homeowners insurance companies. In some cases, your insurer may inspect your roof before issuing a policy.
