The roof is more vulnerable to everyday wear and tear because it’s exposed to the elements all year round. That’s why it’s important to assess the overall condition of the roof regularly to protect the entire structure from water damage.

Wayward tree branches, rain, snow, sleet and harsh winds can damage even the most durable roof. Inspecting the roof from the inside and out helps to determine if it requires repair or replacement. In today’s post, we are listing down tips to help you decide if your roof requires repair or a complete overhaul:

How to Check for Damage

To check for damage, see if the roof deck is uneven or saggy. Check if the structural components of the roof – including the insulation and waterproofing layer – is damaged or intact.

Other glaring damages include water leaks, dark spots, and fungal growth. If the shingles are blistering, curling, buckling, rotting or missing, then the roof needs extensive repair.

Scan the roof for signs of wear, missing shingles, and damage especially around the vents, pipes, and chimney. Check the gutters for shingle granules. Shingle granules, which look like grains of sand, are a sign of extensive roof damage.  Finally, look for evidence of decay, moisture, and mold.

When to Repair the Roof

After completing an assessment of the roof, see if patching is enough to resolve the problem. Ideally, you want to prioritize on leaky or rotting parts of the roof. Damaged roof caused by branches or wind can be patched up quickly. Just remove the damaged shingles and slide new ones in place. But be sure to replace the roofing material underneath the damaged shingles too.

Always use shingles in the same color as the rest of the roof. Mismatched shingles don’t just look unattractive from afar, it will also decrease the overall value of your home. If you intend to sell your home in the next decade, we strongly recommend a partial or complete replacement.

When to Replace the Roof

Old Roof

Generally, roofs will last about 20 to 25 years. If the roof is older than 20 there’s a huge chance that you need to replace the entire roof.

Curled, Buckled Shingles

If the shingles show extensive damage such as curling, buckling or rotting, it’s a sign that the material has exceeded its life expectancy. If the shingles are breaking down and losing granules then you have to replace the roof with a new one.

Damaged Roof Valleys

Roof valleys are the weakest part of a roof. Snow or rain flow through the valleys and into the gutter. If the valley is weak, it could lead to water damage. If the shingles are missing or breaking apart in the roof valleys, then you need to replace the entire roof.

Chimney Flashing

If the old chimney flashing is made up of tar or cement, then it will only take several years to see signs of extensive damage. And if the flashing is damaged, you’d have to replace the old roof. We recommend replacing the flashing with durable, water-tight fitting such as a metal flashing system.

Daylight Permeation

Go to the attic to see if daylight is permeating from the roof. Check for moisture in the insulation too. If daylight is passing through the roof, you need to replace the entire roof.
