Ways to Save Money on Garage Roof Replacement

Replacing your garage roof can be costly, but there are ways to get it done affordably if you’re willing to put in some effort.

• The easiest way to save is to use asphalt shingles instead of more expensive materials like slate or metal roofing. Asphalt shingles cost around £50/m2 installed.
• Consider using lighter-coloured shingles since they reflect heat and can last 5-10 years longer than dark shingles.
• Install roofing felt beneath the shingles for an extra weather barrier. It only adds around £10/m2 but helps prevent leaks.
• If your garage framing is in good shape, you may be able to install new shingles over the existing ones. This saves on the labour costs of tearing off the old roof.
• Carefully inspect and repair any sagging roof decking before re-roofing. This prevents expensive structural issues down the road.
• Always get multiple quotes and ask about any potential discounts for bundled services or paying in cash. Many roofers offer deals to win your business.
• Consider DIYing the tear-off and disposal if you’re physically able. This can reduce labour fees by 20-30%.

With smart planning and cost-cutting measures, you can get a quality garage roof replacement done affordably. Protecting your investment is worth the effort.

Should You Repair or Replace Your Garage Roof?

Determining whether to repair or replace your garage roof can be tricky. Here are some tips to decide which option is best for you:

• Inspect the roof carefully. If more than 20% of the roof is damaged or worn, replacement may be the better option. Repairs on badly damaged roofs often fail quickly.
• Consider the roof’s age. If it is nearing the end of its lifespan (20 years for asphalt shingles), a replacement can avoid issues down the road. Roof repairs on an ageing roof are temporary.
• Evaluate the condition of the roof decking/framing. Sagging or rotted decking will lead to future leaks no matter how well you repair the surface. Replacement provides an opportunity to correct structural issues.
• Compare costs of repair vs. replacement. The price difference may be smaller than expected, especially if you need extensive repairs. Replacing now can save you money long-term.
• Think about convenience. Replacing the roof completely avoids multiple repair episodes and potential future leaks. However, repairs require less time and disruption.
• Assess the roof’s current leak situation. Numerous leaks may mean the roof has reached the end of its service life. Repairs would likely be temporary.
• Consider any upgrades in roofing materials. Replacement allows you to install a longer-lasting roof with better durability and even improve aesthetics.

Carefully weighing these factors will help you make a replacement decision for your garage roof. Protecting your investment is key.

Getting Quotes for Garage Roof Replacement

Getting quotes from multiple roofing contractors is important when considering a garage roof replacement. Here are some key questions to ask:

1. Are you licensed and insured? A contractor should carry liability and workers’ comp insurance and be licensed if required in your state.
2. Will you provide a detailed written estimate? Get quotes in writing listing materials, labour, timeline, warranty, and cost breakdown.
3. What materials do you recommend? The type of shingles or metal used can impact durability and cost.
4. Will you handle the permit and inspection? Make sure the contractor will arrange for any required building permits and pass inspections.
5. How long will the project take? Get an estimated start date and project duration.
6. Can you provide references from recent jobs? Reputable contractors should be able to provide local references.
7. Do you offer a workmanship warranty? Good roofers will guarantee their materials and labour for a certain number of years.

Asking the right questions upfront ensures you get accurate, comparable quotes from qualified professionals.
