Re-roofs
Commercial, Industrial and Institutional Roof Replacement in Cambridge and Southwestern Ontario
A sturdy roof protects your business from the elements. It has to withstand strong winds, heavy downpours, snow and ice accumulation. Whether it’s a repair or a new installation, your roof must be properly maintained to protect your investment. Commercial, industrial and institutional roofs can suffer from multiple roofing problems.
Roof replacement is a crucial investment in maintaining the structural integrity and safety of any business property. Over time, weather exposure, aging materials, and wear and tear can compromise a roof’s performance. At Grand Valley Roofing & Coatings Inc we aim to provide roof replacement services in Cambridge and entire Southwestern Ontario, ensuring that your property remains protected and durable for years to come.
Does Your Commercial/ Industrial/Institutional Roof Need Repair or Replacement?
We can also help you decide whether you need a complete roof replacement or just roofing repair solutions depending on the current condition of your roof. If the roof damage is minimal, fixing leaks and replacing cracked or damaged membranes will suffice, and we can repair the roof. However, if the damage is significant, we may suggest replacing it completely.
Water leaks can also damage the roof decking. Further problems indicating a repair or re-roofing may be necessary could include one or more of the following:
-
Lack of roof maintenance.
-
Failure to correct minor problems.
-
Flashing and drain problems.
-
Failure of roof perimeters, e.g., gravel stops.
-
Poor design choices.
-
Weathering and wind damage.
-
Water damage and pooling.
-
Missing gravel, cracked roof membrane, and/or adhesive bubbling through the membrane.

Reasons You May Need a Roof Replacement
Various factors can indicate the need for a roof replacement:
Lack of Roof Maintenance
Roof maintenance is often forgotten or ignored until a leak appears or your insurance company lets you know that your roof needs replacing. Some owners believe roofs last as long as the manufacturer says they are designed for, and when it gets close to that time, you should check your roof to see if it needs replacing. Others know that, in reality, it is a roof maintenance plan that allows the roof to last as long as it is designed to. In addition, roofers know that weather and building location can impact the roof's life and that inspections are the key to the longevity of your roof. Lack of roof inspections and maintenance can equal early roof replacement and create additional expenses for owners.
Failure to Correct Minor Problems
The biggest cause of premature roof failure is the inability to locate and correct minor problems; the lower the roof slope, the greater the impact. Insufficient ventilation can markedly decrease the life of the roof. Also, ventilation will not solve the problem of water leaking into the attic or building.
Failure in Gravel Stops
The heat on the roof expands and contracts the metal, and before long, the bonding membrane develops cracks and/or separates from the base material, where leaking occurs. While easy to repair, these problems are often overlooked. Yearly inspections can spot this problem.
Weathering & Wind Damage
The type of roofing material dictates the product's life; the less organic the material, the longer the life. Hail, air pollution, and a salt-laden atmosphere can damage roofs. The most significant factor in prolonging a roof's life is adequate fastening of the roofing material to the deck and perimeter. High winds loosen the roofing materials, and no roof can withstand extreme winds and flying debris.
Water Damage & Pooling
Out of sight, out of mind. Often, the first indicator of a roof issue is water damage. This is particularly true for flat roofs, where it is easy to forget to check drains or to clean off plant residue and garbage from the roof when it is not easily seen.
Water collecting on a roof can magnify UV rays and decrease the roof's life, particularly for BUR and bituminous-based roofs. Root-top units without proper drainage can compound the problem.
Flashing and Drain Problems
The function of flashing is to provide a watertight connection between the roof and projections. Many early roof leaks result from flashing problems, and prompt repair will extend the roof's life. Roof drains remove water as quickly as possible and should be inspected frequently for blockages.
Poor Design Choices
This slope-to-flat roof transition will fail prematurely due to the material's expansion and contraction at the change in deck direction, causing membrane splits. In addition, incompatible roof materials, poor drainage, sagging structures, and roof-on-roof designs can all contribute to premature roof failure.
Missing Gravel, Cracked Roof Membrane and/or Adhesive Bubbling Through the Membrane
Over time, wind, rain, and snow can reduce the amount and effectiveness of gravel on roofs. With less protection, the membrane can dry out faster, causing cracking and blistering. This allows air to get trapped under the membrane, heated by the sun and stretched permanently. The adhesive can begin to release and leak through the membrane. Now, water can penetrate and cause leaking.

It takes a great deal of design to create proper drainage.
