Types of Roofs We Seal

We provide roof sealing services for many types of roofs, suited to different building needs. Each roof requires specific materials and techniques to ensure lasting protection and proper coverage.

Residential Roof Sealing

We seal residential roofs made from materials like asphalt shingles, tiles, metal, and wood. Our process helps protect homes from water leaks, mold, and weather damage.

We use sealants that match the roof’s material to keep it flexible and strong. With regular sealing, homeowners can extend the life of their roofs and avoid costly repairs. Our team inspects the roof surface to fix small cracks or loose sections before applying the sealant for best results.

Commercial Roof Sealing

Commercial roofs tend to be larger and may use materials like built-up roofing, single-ply membranes, or modified bitumen. We tailor our sealing methods to fit these materials and the roof’s unique structure.

Our sealing work creates a waterproof barrier that prevents leaks and damage from harsh weather, UV rays, and foot traffic. Maintaining these roofs extends their lifespan and reduces maintenance costs for businesses. We also follow safety standards to protect workers and the building during the sealing process.

Sloped and Flat Roofs

Sloped roofs usually have better drainage, so sealing focuses on joints, edges, and fasteners to stop leaks. Flat roofs need a thorough seal over the whole surface to prevent standing water.

We use high-quality coatings suited for each roof type:

• For sloped roofs, flexible sealants that adjust to roof movement.
• For flat roofs, thick, waterproof membranes.

Each sealing technique improves durability and resists damage caused by weather and temperature changes.

Our Roof Sealing Process

We focus on careful steps to ensure your roof is sealed properly. This includes checking the roof’s condition, cleaning and prepping the surface, applying the sealant using the right technique, and making sure everything meets quality standards.

1. Roof Inspection and Assessment

First, we inspect your roof thoroughly. We look for any damage like cracks, loose shingles, or old sealant that needs to be removed. This helps us understand what repairs are needed before sealing. We check how the roof is draining water and identify areas prone to leaks. This step is key because sealing over damaged parts won’t fix existing problems. Our team also notes roof material type to choose the best sealant.

2. Surface Preparation

Preparing the roof surface is vital for strong adhesion. We start by cleaning dirt, debris, and old coatings using power washing or hand tools, depending on roof condition. Next, we repair small cracks or holes with roofing cement or patches. We ensure the surface is dry and smooth before sealing, as moisture or rough spots reduce sealant effectiveness.

3. Application

We apply sealant using brushes, rollers, or sprayers, based on roof type and slope. For flat roofs, spraying provides even coverage quickly. Steeper roofs may need brushing for control. Our team applies multiple layers for durability, letting each layer dry completely before the next. We use only certified sealants suited to withstand local weather, protecting the roof against rain, UV rays, and temperature changes.

4. Final Quality Check

After sealing, we inspect the entire roof to ensure full coverage and proper thickness. We look for missed spots, bubbles, or uneven areas that need touch-ups. We test water drainage to confirm no pooling occurs post-sealing. Finally, we provide you with maintenance advice to keep the roof in good condition and extend the seal’s lifespan.

Signs You Need Roof Sealing

When a roof starts showing signs of wear, it can lead to bigger problems if left untreated. We pay attention to water leaks, visible damage, and how old the roof is to decide when sealing is necessary. These are clear signs that require prompt action.

Water Leaks and Staining

Water leaks inside the house are a red flag. If we see water spots or stains on ceilings or walls, it usually means moisture is getting through the roof. These stains often appear as dark patches or rings.

Leaks can also cause mold or mildew, which damage the structure and can affect indoor air quality. Roof sealing prevents water from penetrating weak spots, stopping leaks before they cause more damage.

Checking the attic for wet insulation or damp wood helps spot leaks early. If we find any, roof sealing is one of the best ways to fix the issue and avoid costly repairs.

Visible Roof Damage



Cracks, blisters, or peeling on the roof surface show that the protective layer is failing. We look closely at shingles, tiles, or roofing membranes for such damage.

Damaged areas allow water and debris in, which speeds up roof deterioration. Loose or missing shingles are also signs that sealing and repair are needed.

Regular inspections help us find these problems early. Sealing these spots restores protection and extends the roof’s life by keeping it sealed against the elements.

Age-Related Wear



Roofs naturally wear out over time. As a roof ages, the materials dry out, crack, or lose flexibility. When a roof nears 10-15 years or more, its chance of leaks and damage increases.

We assess how much wear the roof has from sun exposure, weather, and use. Roof sealing adds a protective layer that slows down the aging process.

Applying sealants can save money by avoiding early replacement. It’s a smart step to keep an older roof functional and safe for longer.
