Top 5 Factors that Determine the Cost of Roof Repair

Your home’s roof is one of the most essential components of its structural integrity. Not only must it be sturdy and strong enough to withstand a vast array of environmental elements, but most importantly, it must protect you and your family from weather, including the heat, cold, rain, sleet, snow, wind and more.

Over time though, those environmental factors eventually wear down — even on the strongest of roofs. Buckling, missing or curling shingles signal 

your roof is in disrepair and needs either a repair or replacement.

A deteriorating or weakened roof can open up your home to other risk factors that threaten its structural integrity. These include:

How Much Does It Cost to Repair a Roof?

While every roof and state of disrepair situation is different, there are some common factors that determine roof repair cost. They include:

1. Type of Roof

Roofing material costs can vary substantially based on the type of roof, and some rooftops require more labor and material. While asphalt shingles may be your least expensive material, slate shingles may be more costly.

2. Slope, Shape, and Pitch

Factors such as slope and pitch affect the cost of a roof repair. When the roof is very steep, for example, the roofing professional needs to spend special attention, materials and time to ensure it is done correctly. A very steep roof also requires extra safety measures to ensure all workers are safe. These measures increase the roof’s repair time, and therefore the cost.

If your roof has a unique shape, it may make repairs more challenging and time-consuming, adding to the cost. Another related aspect is if you have difficult-to-access roof. If your home is tightly clustered or wedged in between to homes, or surrounded by trees, it can take more equipment and time to access the roof as the crew must haul materials and equipment up and down.

3. Roof Size

The size of your roofing repair job will essentially be one of the largest factors that impact your roof leak repair cost, roof shingle repair cost, flat roof repair cost, or other. Because roofing materials are typically sold “by the piece”, rather than by the square foot, a larger roof will require more pieces, and will cost more. If your repair and roof size is extensive, it may be more cost-effective to opt for a roof replacement.

4. Skylights and Chimneys

Unique rooftop elements, such as skylights and chimneys, can increase the cost of a roofing repair job. Wherever there is a skylight or chimney, the roofer needs to work around them meticulously 

and add sealing materials, which could increase the labor and materials costs. These areas, where structures join together, are more prone to leaks if not installed correctly and lead to a future roo

f leak repair cost.

5. Needed Permits

Depending on the extent of your roofing repair project, you might need a permit, and the price of the repair can vary. Be sure to ask your roofing contractor if a permit is needed. In many locations, a permit is only needed for a roof replacement, not a roof repair.

What is mildew growth and how does it affect my roof?

Mildew growth is the spread of mould that grows on surfaces such as; wooden, fabrics, and wallpapers and even on leaves. Mildew growth can severely damage your roof. Mildew growth may not only cause bad odour but also discolour your roof

How does my roof’s slope or pitch impact repair costs?

The slope of your roof generally determines repair costs. The first reason is that a steeper slope (> 6.12 pitch) is not climbable. As such, your repairs company may ask for a little bit more since the staging, labour, and safety required is greater than would be required for a flat roof. Additionally, the pitch determines the underlayment system and hence the cost of the whole roofing repair job. An underlayment on a steeper slope would be costlier than repairing one on a flat roof.

My house has a chimney, will that affect the cost of roof repairs?

A chimney is definitely one of the factors that determine the cost of a roofing repair job. Chimney and the skyline are components of the roofing system that need to be looked at during a repairs and maintenance job. For example, your chimney may require replacement and this will definitely make the repair job costlier
