Frequently asked questions

Questions about asphalt shingles.

How long do asphalt shingles last in Maryland?+

Many asphalt shingle roofs last approximately 15 to 30 years. Actual service life depends on material quality, installation, ventilation, exposure, maintenance, and roof design.

Can damaged asphalt shingles be repaired?+

Sometimes. Repairability depends on the roof’s age, brittleness, surrounding condition, seal strength, damage extent, and whether compatible replacement shingles are available.

Does granule loss mean the roof must be replaced?+

Not automatically. Some granule loss is normal, but widespread bare spots, exposed fiberglass, uneven wear, or accelerated deterioration should be evaluated.

Should asphalt shingles be inspected after strong wind?+

Yes. Wind can lift tabs, break seals, crease shingles, expose fasteners, or remove materials even when the roof looks mostly intact from the ground.
