Roofing cement is a versatile sealant used to repair leaks, secure flashing, and seal seams on asphalt and low-slope roofs. When working on a project, homeowners often turn to Ace Hardware for reliable roofing products, including a variety of roofing cements and associated sealants. This guide walks through what roofing cement is, the options available at Ace Hardware, proper application techniques, safety tips, and buying considerations to help Americans choose the right product for their repair needs.
What Is Roofing Cement And How It Works
Roofing cement is a thick, asphalt-based sealant designed to imperviously seal roof seams, patch small holes, and bond materials like shingles, flashing, and metal gutters. It remains pliable after application, allowing for expansion and contraction with temperature changes. The material creates a waterproof barrier that minimizes wind-driven leaks and helps extend the life of aging roofing components. It is commonly used in low-slope roofs, flat roofs, and repair scenarios where traditional asphalt shingles require a flexible sealant rather than rigid cement.
Types Of Roofing Cement Available At Ace Hardware
Ace Hardware stocks several roofing cement formulations designed for different climates and repair needs. Common options include:
- All-Weather Asphalt Roofing Cement: A versatile, weather-resistant option suitable for year-round use. It bonds shingles and seals seams against wind uplift and rain intrusion.
- Fiber-Reinforced Roofing Cement: Contains reinforcing fibers for added strength in high-stress areas such as parapets, chimneys, and flashing joints.
- Flashing And Roof Patch Cements: Special blends designed for flashing repairs, gutters, and small punctures along seams and valleys.
- Primer-Ready Formulations: Some products allow for quick adhesion without a separate primer, ideal for small repairs and emergency fixes.
In addition to roofing cements, Ace Hardware often offers sealants and mastics that complement roofing cement, such as elastomeric coatings, roof caulks, and metal flashing sealants. Choosing the right formulation depends on roof type, climate, and the repair’s scope.
When To Use Roofing Cement
Roofing cement is best suited for:
- Sealing loose shingles around edges and corners where nails are missing or damaged.
- Patch repairs for punctures, cracks, or small holes in low-slope roofs or built-up roofs.
- Sealing around flashing, vent pipes, and chimneys to prevent water intrusion.
- Temporary emergency repairs when weather prevents a quicker, more durable fix.
Note that roofing cement is typically a temporary solution for significant damage or high-traffic roof areas. For large leaks, structural issues, or steep-slope roofing, a professional assessment and more permanent materials may be required.
How To Apply Roofing Cement
Effective application improves sealing and longevity. Follow these steps for a typical patch or seam repair:
- Clean the area to remove dirt, dust, and loose debris. A wire brush or stiff broom helps.
- Apply a liberal bead of roofing cement along seams, around flashing, and over the patched area.
- Press shingles or flashing into the cement and smooth with a putty knife or trowel to create a tight bond.
- For patches, cover the patched area with a thin film of cement and embed a patch material if prescribed by product directions.
- Wipe away excess material to prevent staining or staining on the roof surface.
- Allow to cure according to product instructions, typically avoiding heavy loads or rain for the recommended period.
Temperature matters: apply during moderate temperatures and avoid extremely cold or hot conditions to ensure proper adhesion and curing. Always read the product label for specific drying times and primer requirements.
How To Choose The Right Roofing Cement
Key considerations when selecting a product at Ace Hardware:
- Roof Type: Low-slope or flat roofs benefit from flexible, all-weather formulas. Shingle roofs often work with standard asphalt cement for small repairs.
- Climate: Regions with frequent rain, snow, or freeze-thaw cycles require more weather-resistant blends and proper curing characteristics.
- Repair Scope: Minor patches may use standard roofing cement, while flashing or heavy-load zones benefit from fiber-reinforced formulas.
- Cure Time: Some products cure quickly, enabling faster repairs; others cure slower but offer longer-term flexibility.
- Compatibility: Ensure the cement adheres well to asphalt shingles, metal flashing, or tar paper, depending on the repair.
Always consult Ace Hardware staff for product recommendations based on local climate and roof composition. Reading customer reviews and product datasheets can also guide selection.
Storage, Handling, And Safety
Proper storage preserves performance. Store roofing cement in a cool, dry place away from direct sunlight and heat sources. Keep containers tightly closed and upright to prevent leakage. Use gloves and eye protection during application to avoid skin and eye contact. Ventilate well when using solvent-based cements, and wipe up spills promptly to prevent slips or stains on surfaces. Dispose of empty containers per local regulations and product guidelines.
Brand Options At Ace Hardware
Ace Hardware carries a range of trusted brands alongside its own store-brand options. When choosing a brand, consider availability, price, and the specific formulation. Popular brands often found at Ace include:
- Henry and other established asphalt cement brands with proven performance for roof repairs.
- Ace Hardware Store Brand mastics and cement products that deliver reliable adhesion for common residential repairs.

Buying Tips And Practical Tips For DIY Roof Repairs
To maximize results and minimize rework, consider these practical tips:
- Prepare a small area test if an unfamiliar formula is used to verify adhesion and cure time before full-scale application.
- Combine roofing cement with compatible sealants for larger joints and seams to extend durability.
- Keep a basic repair kit on hand: putty knife, gloves, brushes, and a damp cloth for quick cleanup.
- Store extra cement in a sealed container to avoid drying out; label with the date of purchase for freshness.
- Document repairs for future maintenance planning and to guide inspections by roofing professionals.
