Roofing Contractors Near Me

If you’re not confident in your ability to perform a thorough inspection or lack the necessary equipment, consider hiring professional roofing contractors near you. Experienced contractors have the knowledge and expertise to identify and address roofing issues effectively.

Visual Inspection

Start with a visual inspection of the entire roof surface. Look for signs of damage, wear, or any visible abnormalities. Pay attention to the following:

Roof Membrane: Examine the roofing membrane for cracks, blistering, or punctures. These issues can lead to water infiltration.

Flashing: Check the flashing around roof penetrations like vents, skylights, and HVAC units. Loose or damaged flashing can cause leaks.

Drainage Systems: Ensure that water flows away from the roof surface efficiently. Proper drainage prevents ponding water, which can lead to leaks and structural damage.

Interior Inspection

Inspect the interior of your building for signs of roof damage or leaks. Common indicators include water stains on ceilings or walls, mold growth, and musty odors. Address these issues promptly to prevent further damage.

Roofing Ventilation

Proper roofing ventilation is a critical aspect of maintaining your commercial roof’s longevity and performance. Inadequate ventilation can lead to moisture buildup in the attic or roof space, which can cause various problems, including:

Roof Deck Damage: Moisture can damage the roof deck, compromising its structural integrity.

Mold and Mildew Growth: Excess moisture can lead to mold and mildew growth in the attic or insulation, posing health risks and further structural damage.

Energy Efficiency: Poor ventilation can result in higher energy bills, as it can cause temperature imbalances in your building.

Roofing Material Damage: Moisture can deteriorate roofing materials, reducing their lifespan.

To ensure adequate roofing ventilation:

Inspect Ventilation Systems: Check that roof vents, soffit vents, and exhaust fans are in good condition and free from blockages.

Address Insulation Issues: Proper insulation can help regulate temperature and moisture in the attic space. Ensure insulation is installed correctly and is in good condition.

Consult a Professional: If you’re unsure about your roof’s ventilation, consult with a roofing contractor or HVAC specialist. They can assess your system’s adequacy and make recommendations for improvements.

Roofing Safety

Safety should always be a top priority during a roof inspection. Commercial roofs can be hazardous environments, and taking appropriate safety precautions is crucial.

Personal Protective Equipment (PPE)

Wearing the right PPE is essential to protect yourself during a roof inspection. Ensure you have the following items:

Hard Hat: Protects your head from falling objects.

Safety Harness: Provides fall protection and should be worn if you’re working near roof edges or openings.

Non-Slip Footwear: Choose shoes with good traction to prevent slips and falls.

Gloves: Protect your hands while handling roofing materials or equipment.

Safety Glasses: Shield your eyes from debris or potential hazards.

Weather Conditions

Consider the weather conditions when planning your roof inspection. Avoid inspecting the roof during adverse weather, such as rain, snow, or strong winds, as these conditions can increase the risk of accidents.

Fall Protection

If your roof has potential fall hazards, such as unprotected edges, openings, or skylights, use appropriate fall protection equipment, such as guardrails, safety nets, or personal fall arrest systems.

Ladder Safety

If you need to access the roof using a ladder, follow ladder safety guidelines:

Ensure the ladder is in good condition and set on stable ground.

Maintain three points of contact while climbing (two hands and one foot or two feet and one hand).

Extend the ladder at least three feet above the roof edge for safe access.

Secure the ladder to prevent slipping or tipping.

Training and Certification

If you or your team are conducting roof inspections, ensure that you have proper training in roof safety and fall protection. Certification and ongoing education are essential for maintaining safety standards.

Working with a Spotter

Having a spotter on the ground can provide an extra layer of safety during roof inspections. They can help monitor your movement and alert you to potential hazards.

Emergency Plan

Establish an emergency plan before starting any roof work. Ensure everyone on the roof knows how to contact emergency services, and have a first aid kit readily available.

Common Roofing Issues to Look For

Now that you’ve covered the basics of safety and general inspection, let’s delve into common roofing issues you should be on the lookout for during your inspection.


Water infiltration is one of the most common roofing issues. Signs of leaks include water stains on ceilings, walls, or insulation, as well as damp spots or visible water in the attic or on the roof deck. When inspecting for leaks:

Check for Damaged Membrane: Inspect the roofing membrane for cracks, tears, or punctures that may allow water to penetrate.

Examine Flashing: Loose or damaged flashing around roof penetrations can be a source of leaks.

Inspect Roof Penetrations: Make sure that any roof penetrations, such as vents and pipes, are properly sealed and not leaking.

Check Roof Drains: Ensure that roof drains are clear and functioning correctly to prevent water from ponding on the roof.

Ponding Water

Ponding water occurs when water accumulates on the roof’s surface and doesn’t drain properly. It can lead to structural damage and leaks. Look for areas where water tends to collect and address the underlying drainage issues.

Roof Material Damage

Inspect the condition of your roofing materials, whether they are shingles, single-ply membrane, or another type. Look for signs of:

Cracking or Splitting: These can weaken the roof and lead to leaks.

Blisters or Bubbles: Indicate trapped moisture beneath the roofing material.

Curling or Buckling: May result from age or improper installation.

Missing or Loose Shingles or Tiles: These should be replaced promptly to prevent water infiltration.

Flashing Issues

Flashing is used to seal roof penetrations and prevent water from entering. Inspect flashing around vents, chimneys, skylights, and other penetrations for signs of damage or deterioration.

Roof Penetrations

Ensure that all roof penetrations are sealed correctly to prevent leaks. Check for gaps, loose seals, or damaged vent pipes and address them promptly.

Hail and Storm Damage

If your area is prone to severe weather, inspect the roof for hail or storm damage. Look for dents, cracks, or dislodged roofing materials. Document any damage for insurance purposes.

Poorly Maintained Roofing Equipment

Equipment installed on the roof, such as HVAC units or solar panels, can cause damage if not properly maintained. Ensure that these items are securely anchored, and any rooftop equipment is in good working order.

Vegetation and Debris

Regularly remove vegetation, leaves, branches, and debris from the roof surface. Accumulated organic matter can trap moisture and promote deterioration.

Roofing Ventilation

As mentioned earlier, inadequate roofing ventilation can lead to various problems. During your inspection, pay attention to:

Blocked Vents: Ensure that roof vents and exhaust fans are not obstructed.

Insulation Issues: Check the condition and placement of insulation to prevent moisture buildup.

Moisture Signs: Look for signs of excess moisture, such as rust on metal components or mold growth in the attic.

Roof Vent Maintenance: Maintain and clean ventilation components as needed to ensure they function correctly.
