5 Essential Tips For Garage Roof Repairs

All year long, your garage roof shields your cars and other stored things from outside elements. However, weather, aging, or poor installation can all cause damage over time, just like any other exterior component of your home. Ignoring required maintenance can result in expensive damage and compromise structural integrity. 

In this blog post, we will take a look at five crucial garage roof repair tips to keep your garage in the best condition possible. 

Top 5 Tips For Garage Roof Repair

#1. Comprehensive Inspections

> Exterior Roof Inspection

The first step in any garage roof repair should always be a thorough assessment of the roof’s external components, which involves:

1. Shingles and Materials:

Begin with a close check of roof shingles or materials. Look for cracks, breaks, or missing granules. Damaged shingles compromise both appearance and protection, so note any for repair or replacement.

2. Roof Flashing:

Inspect flashing around chimneys, vents, etc., ensuring it’s sealed and intact. Flashing guards against water infiltration, so any issues should be promptly fixed to prevent leaks.

3. Gutters and Downspouts:

Check gutters and downspouts for clogs, damage, or improper drainage. Debris can cause improper water flow, roof damage, or leaks.

4. Structural Integrity:

Look for signs of sagging or uneven areas, indicating possible structural issues. Maintaining structural integrity is vital for stability and longevity, so investigate and repair any concerns promptly.

> Interior Attic Inspection

It is equally important to assess the interior roof components in addition to the external assessment.

1. Water Damage:

Look for signs of water damage like stains, mold, or rot in the loft or ceiling space. These can indicate roof leaks needing immediate attention to prevent further damage to the roof structure and garage interior. Prompt identification and repair of water damage can help preserve the roof’s integrity.

2. Insulation and Ventilation:

Check the insulation, if any, and roof ventilation to ensure proper airflow and prevent moisture buildup. Good insulation and ventilation regulate temperature and humidity, reducing condensation and mold growth risks. Maintaining these aspects contributes to the overall health of the roof and garage structure.

3. Roof Framing:

Examine roof framing components (rafters, trusses) for damage or deterioration. Roof framing provides crucial structural support and weight distribution. Address any issues promptly to maintain structural integrity and ensure the roof’s longevity.

#2. Address Common Signs of Garage Roof Damage Promptly

> Water Stains and Leaks:

Water Stains and Leaks

Brown or yellow discolorations on the ceiling or walls indicate water penetration, often caused by damaged shingles, cracks, or improper flashing.

> Damaged Shingles:

Curled, cracked, or missing shingles compromise roof protection, allowing water infiltration. Regular inspection and timely repair prevent more serious issues.

> Sagging Sections:

A sagging or uneven roofline suggests structural issues, potentially from water damage or poor construction. Immediate professional inspection and repair are necessary to prevent collapse.

> Granule Loss:

Accumulated granules in gutters signal aging shingles losing their protective coating. This vulnerability requires repair or replacement to extend the roof’s lifespan.

> Cracks in the Roofing Material:

Cracks in roofing material allow water infiltration, leading to leaks and structural damage. Regular inspections catch and fix cracks before they worsen.

> Algae or Moss Growth:

Algae or Moss Growth

Algae or moss growth indicates excess moisture, accelerating roof deterioration. Cleaning and treatment can prevent further damage.

> Visible Roof Decking Damage:

Visible damage to the roof decking suggests a compromised structure. To maintain roof integrity, professional assessment and repair are necessary.

> Gutter Issues:

Clogged, sagging, or detached gutters indicate roof problems. Regular maintenance prevents water infiltration and identifies issues early.

> Age of the Roof:

Roofs typically last 20-30 years. Approaching or exceeding this lifespan may necessitate repair or replacement for continued protection.

#3. Choose the Right Materials

> Metal Roofing Panels: 

Metal Roofing Panels

Galvanized steel, a premier option for garage roofs, offers exceptional durability and resistance to corrosion and rust. Available in various colors and profiles, it provides versatility and customizable designs that blend well with property aesthetics. With minimal upkeep and easy installation, it reflects heat, helping to regulate temperatures. Its lifespan exceeds 30 years, making it a dependable choice for garage roofs.

> EPDM Roofing Membrane: 

EPDM Roofing

EPDM (ethylene propylene diene monomer) is known for its resilience against weathering and UV rays, ensuring prolonged protection for flat garage roofs. With a lifespan of up to 50 years, it’s cost-effective and requires minimal maintenance. However, proper sealing and installation are necessary for its longevity.

> Asphalt Shingles:

Asphalt shingles are a timeless and cost-efficient option for garage roofs. Durable, easy to install, and available in various hues and designs, they ensure aesthetic consistency when matched with the main house’s roof.

> Modified Bitumen:

Modified bitumen offers a wallet-friendly solution for flat roofs, providing a waterproof and protective layer for the garage. They are relatively easy to install and replace, making them practical for homeowners who prioritize low maintenance. Though not as resilient as some counterparts, they offer satisfactory protection at a reduced cost.

#4. Budget For Garage Roof Repairs

Assess the Damage

  • Initial Inspection: Start by visually examining your garage roof for visible signs of damage, such as missing shingles, leaks, or sagging areas. This will help you understand the repair needs.
  • Professional Evaluation: Seek a professional roofing contractor for a thorough assessment. They can identify hidden issues and provide a detailed report on necessary repairs and costs.

Set a Budget

  • Research Costs: Determine the average cost of garage roof repairs in your area, considering materials, the extent of damage, and labor.
  • Get Multiple Quotes: Obtain quotes from different contractors to compare prices and services offered, ensuring a fair and competitive price.
  • Budget Buffer: Allocate 10-20% of your budget for a contingency fund to cover unexpected expenses during the repair process.

Choose Materials

  • Quality vs. Cost: Balance quality and cost, considering long-term benefits like durability and reduced maintenance expenses.

Explore Financing Options

  • Homeowners Insurance Coverage: Homeowners insurance might cover garage roof repair or replacement for sudden accidents or natural events like storms. But it might not cover wear and tear or neglect, especially for older roofs over 20 years.
  • Manufacturer and Contractor Warranties: Manufacturer warranties cover roof materials, while contractor warranties cover the workmanship, ensuring accountability for any issues with the roof.
  • Extended Manufacturers’ Warranty: Extended manufacturer warranties, lasting up to 50 years, offer more comprehensive coverage for material and installation defects. They often require specific conditions and work done by certified contractors.

Most importantly, schedule routine inspections to catch issues early and extend the lifespan of your garage roof.

#5. Hire A Professional

While some small garage roof repairs are feasible as a DIY project, there are instances in which hiring a qualified and skilled roofing contractor is preferable. It’s best to get professional assistance if the damage is severe, the roof is in bad shape, or you don’t know how to make repairs correctly. A trustworthy roofing contractor can complete the project safely and effectively, guarantee that the work is done correctly, and offer warranties on their labor.

Garage Roof Repair Cost

The cost of repairs varies depending on the type of repair and the materials needed, especially if you’re choosing professional assistance for your garage roof repair. In most cases, garage roof repairs cost from $200 to $1,000, possibly even more if structural work or specific materials are needed. Minor repairs could only cost about $150, but major repairs could cost up to $10,000, depending on the location and extent of the damage.
