Choosing the right shingles is one of the most consequential decisions a homeowner makes, and in High Point, the local climate adds extra stakes to that choice. If you are planning a roof project and want to understand what materials will hold up best, this guide covers what you need to know before any work begins.

Shingles are the most visible part of a roof, but they are also the first line of defense against rain, wind, heat, and hail. In the Piedmont region, that means enduring humid summers, intense UV exposure, occasional ice and freeze-thaw cycles in winter, and the remnants of coastal storms that push through the area each fall. A shingle that performs adequately in a milder climate may fail prematurely here.
Understanding the differences between shingle types, how they are rated, and what supporting components they require will help you ask better questions, evaluate contractor proposals more confidently, and avoid being oversold or undersold on materials.
The two most common asphalt shingle types homeowners encounter are 3-tab shingles and architectural shingles, also called dimensional or laminate shingles. They look similar in photos but differ significantly in construction, weight, durability, and cost.
3-tab shingles are a single-layer product cut to produce three uniform tabs along the bottom edge. They are thinner, lighter, and less expensive than architectural shingles. Their flat, uniform appearance was the standard in residential roofing for decades, but they have largely been replaced in newer construction. Most 3-tab shingles carry wind ratings of 60 to 70 mph and lifespans in the 20 to 25 year range under good conditions.
Architectural shingles are a laminated, two-layer product. The added thickness creates a dimensional, textured appearance that mimics the look of wood shake or slate. More importantly, the extra material adds weight, structural integrity, and resistance to wind and impact. Wind warranties on architectural shingles typically range from 110 to 130 mph, and realistic lifespans run from 25 to 40 years depending on the product line, installation quality, and ventilation beneath the roof deck.
For most High Point homes, architectural shingles represent the better long-term value. The price difference over 3-tab is modest relative to the labor cost of a full roof project, and the performance gap is meaningful given local weather patterns.
Shingle packaging and product sheets reference two rating systems that matter in storm-prone areas.
The UL 2218 standard tests shingles by dropping steel balls of increasing size from a set height and measuring the result. Products are rated Class 1 through Class 4, with Class 4 being the highest. Class 3 and Class 4 shingles use polymer-modified asphalt, sometimes called rubberized asphalt, which allows the material to absorb impact rather than crack or puncture. In hail-prone regions, Class 3 or Class 4 rated shingles are worth the additional cost and may qualify for a discount on homeowners insurance premiums. Check with your insurer before selecting materials.
Wind ratings describe the sustained wind speed a shingle is designed to withstand without lifting or losing seal. Standard architectural shingles carry ratings around 110 mph. Premium lines are rated to 130 mph. These ratings assume proper installation with the correct number of fasteners, correct fastener placement, and a starter strip at all eaves and rakes. Even a high-rated shingle will fail early if installed incorrectly.
Manufacturers publish warranty terms ranging from 25 years to lifetime coverage, but warranty length and actual service life are not the same thing. Warranty terms often involve prorated coverage after a certain period, and they require specific installation conditions to remain valid.
Realistic service life depends on several factors:
A well-installed architectural shingle roof in High Point, properly ventilated and maintained, should realistically perform for 25 to 35 years. Premium impact-resistant products can extend that range.
Shingles are not a waterproof membrane on their own. They are designed to shed water, not stop it entirely. Underlayment is the layer installed directly on the roof deck beneath the shingles, and it serves as a secondary water barrier if shingles are lifted, cracked, or missing.
Traditional 15 lb and 30 lb felt underlayment has been used for decades. It is functional and affordable but can wrinkle during installation, absorbs moisture, and degrades faster than synthetic alternatives.
Synthetic underlayments are lighter, stronger, more tear-resistant, and better at repelling moisture than felt. They are easier to install flat, which reduces wrinkle-related issues, and they hold up better during the window between deck preparation and shingle installation. Most quality installations today use synthetic underlayment as the baseline choice.
Ice and water shield is a self-adhering, fully waterproof membrane applied at vulnerable areas: eaves, valleys, around skylights, and along rakes in colder climates. In High Point, ice damming is less common than in northern states, but applying ice and water shield at the eaves and in all valleys is still considered best practice and provides meaningful protection during heavy rain events.
Proper attic ventilation is one of the most important and most frequently neglected elements of a residential roofing system. Without adequate airflow, heat and moisture accumulate in the attic space and attack the roof from below.
In summer, an unventilated attic can reach temperatures exceeding 150 degrees Fahrenheit. That sustained heat accelerates the breakdown of shingle adhesives, causes the roof deck to dry and warp, and significantly increases cooling costs inside the home. In cooler months, warm interior air rising into a cold attic condenses into moisture, which can cause deck rot, mold growth, and insulation degradation.
A balanced ventilation system pairs intake vents, typically located at the soffits, with exhaust vents at or near the ridge. Air enters at the low point and exits at the high point, creating continuous airflow across the underside of the deck. Ridge vents combined with continuous soffit venting are generally considered the most effective passive system for residential roofs.
If you are evaluating shingle options and your current attic ventilation is inadequate, addressing ventilation at the same time as the shingle work is the right approach. Installing premium shingles over a poorly ventilated deck is counterproductive.
The black streaking visible on many roofs in the High Point area is caused by Gloeocapsa magma, a type of algae that feeds on limestone filler used in asphalt shingles. It does not immediately damage shingles structurally, but it degrades the granule surface over time, reduces reflectivity, and significantly affects curb appeal and perceived home value.
Most manufacturers now offer algae-resistant shingles that incorporate copper or zinc granules into the surface coating. These shingles are labeled with an AR designation and carry algae-resistance warranties, typically 10 to 25 years depending on the product. In a humid climate like the Piedmont, specifying algae-resistant shingles is a straightforward decision that costs very little extra at the time of installation.
Homeowners do not always know when shingles have crossed from aging normally into active failure. Some warning signs are visible from the ground. Others require a closer look from a professional inspection.
When you are reviewing contractor proposals, shingle selection can seem overwhelming. Here is a straightforward framework for evaluating your options.
Under normal conditions with proper installation and adequate ventilation, architectural asphalt shingles typically last between 25 and 35 years in the Piedmont region. Premium impact-resistant products can extend that range. 3-tab shingles tend to reach the end of their functional life around 20 to 25 years.
High Point does experience hail events, particularly from spring and summer thunderstorm activity. Class 3 or Class 4 impact-resistant shingles offer meaningful protection against this type of damage and may reduce insurance premiums. Whether they are necessary depends on your risk tolerance and insurance situation. They are worth discussing with both a roofing professional and your insurance provider before making a final decision.
A manufacturer warranty covers defects in the shingle product itself. A workmanship warranty, offered by the installing contractor, covers issues caused by installation errors. Both matter. A shingle can fail because of poor installation rather than a material defect, and in that case only the workmanship warranty applies. Always confirm what each covers and for how long.
In some cases, a second layer of shingles can be installed over an existing layer without a full tear-off, which reduces labor and disposal costs. However, this approach has limitations. It adds weight to the structure, makes it harder to inspect the deck, and eliminates the opportunity to address ventilation or deck damage issues. Most professional recommendations favor a full tear-off for a roof that is being replaced rather than repaired.
Isolated damage affecting a small area can often be addressed with targeted repairs. When deterioration is widespread across the roof surface, when the shingles are approaching or past their expected service life, or when the deck shows structural concerns, a full replacement is typically the more cost-effective path. A professional inspection is the most reliable way to make that determination.
Understanding shingle types, ratings, and system components puts you in a much better position to make a confident decision.
