How to Repair Asphalt Flat Roof?

Your asphalt flat roof has been holding up well over the years, but recently, you’ve noticed a few issues—maybe some cracks, pooling water, or even a leak. Don’t panic! While these problems might seem daunting, with the right approach and a little know-how, you can repair your asphalt flat roof and keep it in top shape for years to come. Whether you’re a DIY enthusiast or simply want to understand the process before hiring a pro, this guide will walk you through the steps of how to repair an asphalt flat roof.

Understanding Asphalt Flat Roofs

First things first, let’s get familiar with what we’re working with. Asphalt flat roofs are popular for their durability, cost-effectiveness, and ease of installation. Unlike sloped roofs, flat roofs have a slight pitch, typically about 1-10 degrees, to allow water to drain. However, they can still be prone to issues like water pooling, which can lead to damage over time. Asphalt, often modified with materials like rubber or plastic to increase flexibility and durability, is used as the waterproofing layer on flat roofs. Over time, the sun’s UV rays, weather conditions, and general wear and tear can cause this layer to degrade, leading to cracks, blisters, or leaks. That’s where roof repair comes into play.

Identify the Problem Areas

Before diving into repairs, you need to know what you’re dealing with. Start by thoroughly inspecting your roof for any signs of damage. Here’s what to look for:

Cracks and Blisters: Asphalt can crack over time, especially if it’s been exposed to extreme weather conditions. Blisters, which are bubbles of trapped air or moisture under the asphalt, can also form and eventually lead to cracks.
Pooling Water: Flat roofs are notorious for poor drainage. If you notice areas where water tends to pool after rain, this could indicate a problem with the roof’s pitch or drainage system.
Leaks: Water stains on your ceiling are a clear sign of a leak. Trace the leak to its source on the roof, as it may not be directly above the visible damage.
Loose or Missing Gravel: If your roof has a gravel layer, check for areas where the gravel has worn away, exposing the asphalt below.

Clean the Roof Surface

Once you’ve identified the problem areas, it’s time to clean the roof. Dirt, debris, and old, loose material can prevent the repair materials from adhering properly. Here’s how to clean your roof:

Remove Debris: Use a broom or blower to clear leaves, branches, and any other debris from the roof surface.
Clean the Surface: For a thorough clean, use a pressure washer on a low setting to remove dirt and old roofing material. Be careful not to damage the asphalt or cause further issues.
Dry the Roof: Make sure the roof is completely dry before proceeding with repairs. Any remaining moisture can compromise the effectiveness of your repairs.

Repair Small Cracks and Blisters

For small cracks and blisters, you can use a simple patching method. Here’s how:

Cut Open Blisters: If you find any blisters, carefully cut them open with a utility knife. Be sure to make a small X-shaped cut, allowing the trapped air or moisture to escape. Press the blister flat.
Apply Roofing Cement: Use a trowel to apply roofing cement under the flap you created with your X-cut. Press the flap down and cover it with more roofing cement, smoothing it out with the trowel.
Reinforce with Fabric: For added durability, apply a layer of fiberglass roofing mesh over the cement. Cover the mesh with another layer of roofing cement and smooth it out.
Seal Cracks: For small cracks, apply roofing cement directly into the crack using a trowel or putty knife. Be sure to fill the crack completely and smooth the surface.

Address Larger Damage

If your roof has larger areas of damage, like extensive cracking or large sections of worn asphalt, you may need to replace portions of the roofing material. Here’s how:

Cut Out Damaged Areas: Using a utility knife, cut out the damaged section of the asphalt roofing. Be sure to cut at least 2 inches beyond the visible damage to ensure you’re removing all compromised material.
Prepare the Surface: Clean and dry the exposed area thoroughly, ensuring there’s no moisture or debris.
Install a New Patch: Cut a piece of asphalt roofing material to fit the area you removed. It should overlap the existing roofing by at least 2 inches on all sides. Apply roofing cement to the exposed area and press the new patch into place.
Seal the Edges: Apply roofing cement around the edges of the patch to seal it completely. For added protection, cover the patch with fiberglass mesh and another layer of roofing cement.

Prevent Future Damage

Repairing your asphalt flat roof is only part of the battle. To ensure your roof stays in good condition and to prevent future issues, consider the following maintenance tips:

Regular Inspections: Inspect your roof at least twice a year, preferably in the spring and fall. Look for signs of damage and address them promptly.
Keep It Clean: Regularly clean your roof to remove debris that could trap moisture and cause damage. Pay special attention to gutters and drains, ensuring they’re clear and functioning properly.
Improve Drainage: If you notice pooling water, consider installing additional drainage systems or adjusting the pitch of your roof. This might involve professional help but will save you from more costly repairs in the long run.
Apply a Roof Coating: Consider applying a reflective roof coating to your asphalt flat roof. These coatings can protect the asphalt from UV damage, reduce heat absorption, and extend the life of your roof.

When to Call a Professional

While many roof repairs can be tackled by a confident DIYer, there are times when it’s best to call in the pros, especially when it comes to roof repair Newmarket. If you’re dealing with extensive damage or if you’re unsure about the condition of your roof, a professional roofing contractor can provide expert advice and repair services. A professional can also perform a comprehensive inspection, identifying potential problems that might not be visible to the untrained eye. Plus, they have access to specialized tools and materials that can make the repair process more effective and long-lasting.
