Frequently Asked Questions

Have questions about roof inspections, roof leaks, asphalt shingles, or metal roofing? Here are clear answers from a local roofing contractor team serving the San Jose area and nearby communities.

Do I really need to check my roof?+

Your safety and confidence in getting up on your roof is critical. A full inspection is going to require that you go up and take a look. Do not hesitate to get a roofing contractor to do your inspection for you.

There are some things you can do from the ground or inside. It will not constitute a real inspection, but it can help you gauge how urgent it is to call your roofer.

How many types of asphalt shingles are there?+

There are two types of asphalt shingles:

  • Organic - composed of an organic felt (usually paper) saturated with asphalt.
  • Fiberglass - has a layer of fiberglass embedded in it.

Both are good roofing products. Fiberglass is more commonly used because it is less expensive. Organic shingles are heavier, which can make them a good choice for climates with high winds.

What can I check for without getting on the roof?+

First, visually inspect the roof from outside from the best angle you can find. Look for obvious issues like debris or missing shingles.

You can also go into the attic and look for these telltale signs of roof problems:

  • Visible daylight through the roof or around chimneys or vents.
  • Dark stains that might indicate leakage.
  • Evidence of insects, mold, or mildew.
If you see any of those, call TRIO Roofer with a sense of urgency.
What do I look for when I am on the roof?+

Overall, you are looking for damage or anything that could become a potential leak:

  • Debris - Leaves and branches can collect water and weaken your roof. Clean affected areas.
  • Open gaps - Check around vents, chimneys, and plumbing boots. Repair openings and inspect below for water damage.
  • Missing shingles - Bare spots can lead to water seeping into your attic.
  • Shingles lifting - Lifting shingles often turn into missing shingles.
  • Mold and moss - Moss can indicate drainage or moisture issues that should be addressed.
  • Gutters - Clear debris and make sure gutters are securely attached.
If you see any of those, call TRIO Roofer with a sense of urgency.
Isn’t metal roofing expensive?+

In absolute dollars, a metal roof costs more than asphalt, about the same as cedar shake or tile, but less than slate. Considering durability, metal is one of the best long-term roofing values.

What would happen if iron nails were used to secure sheets of copper roof?+

They would corrode rapidly due to electrolytic action between the iron and copper. Galvanized nails can be even worse. Copper (or possibly brass) nails are typically needed for that job.

How do you trace leaks in a roofing system?+

The actual source of a roof leak can be located far away from where the water drip or damp stains appear. Start by checking roof areas exposed to prevailing winds.

On flat roofs, check for ponding (puddles of water sitting on the roof surface). Flat and low-pitched roofs covered in mineral felt, asphalt, GRP (fiberglass), EPDM, or rubber sheeting can be prone to leaking at joints and at junctions where the roof meets walls or parapets.

How do you repair roof leaks in a flat roof?+

For flat and low-pitched roofs, the approach may depend on urgency and weather conditions.

Repairs using sheet materials: Traditional flat roofing surfaces (mineral felt and bitumen) may be replaced using the same materials. Disposal of old roofing felts and bituminous coatings can incur significant costs due to environmental charges.

Permanent repairs: Low-pitched and flat roofs, balconies, and walkways can often be repaired economically with liquid membranes that provide a seamless, flexible coating with strong adhesion and UV resistance.

On pitched roofs, broken or displaced tiles or slates are often the cause of leakages.

Are metal roofs noisy?+

No. It is a common misconception.

How long will metal roofs last?+

Typically 40-60 years, with some lasting well beyond that.

Do metal roofs attract lightning?+

Lightning seeks the shortest route to the ground, usually the highest point regardless of material. A metal roof can help dissipate the charge.

Can you walk on the roof?+

As long as you follow all safety precautions, just like you would on an asphalt roof.

How heavy is metal roofing?+

Metal roofing is considered a lightweight material, about 50% lighter than asphalt.

Does my old roof need to be taken off to install a metal roof?+

Not necessarily. It depends. Many installers install over an asphalt roof, while others prefer stripping down to the sheathing to ensure a good substrate.

I’m concerned a metal roof won’t match my home or neighborhood style. What can I do?+

There are many metal roof styles and colors to meet your needs. We can show you how metal roofing can add value to your home while improving energy efficiency.
